Maintenance procedures are not covered by the warranty. Descale and sanitize the ice machine every six months for efficient operation. If the ice machine requires more frequent detailing and sanitizing, consult a qualified service company to test the water quality and recommend appropriate water treatment.
DETAILED DESCALING/SANITIZING PROCEDURE This procedure must be performed a minimum of once every six months. • The ice machine and bin must be disassembled descaled and sanitized. • All ice produced during the descaling and sanitizing procedures must be discarded. REMEDIAL CLEANING PROCEDURE • This procedure descales the components in the water flow path, and is used to descale the ice machine between the bi-yearly detailed descaling/sanitizing procedure.
Touchscreen Operation For The Clean Cycle STARTING A CYCLE Pressing the clean button will display a Continue/Abort screen, and a warning that pressing Continue will result in a clean cycle that can last up to 35 minutes. WATER CURTAIN/DAMPER OPERATION DURING THE CLEAN CYCLE The water curtain/damper must remain closed during the clean sequence.
Detailed Descaling/Sanitizing Procedure ,Caution Do not mix Cleaner/Descaler and Sanitizer solutions together. It is a violation of Federal law to use these solutions in a manner inconsistent with their labeling. nWarning Wear rubber gloves and safety goggles (and/or face shield) when handling Ice Machine Cleaner or Sanitizer. Ice machine cleaner/descaler is used to remove lime scale and mineral deposits. Ice machine sanitizer disinfects and removes algae and slime.
Step 1 Open the front door to access the evaporator compartment. Ice must not be on the evaporator during the descaling/sanitize cycle. Follow one of the methods below: • Press the power switch at the end of a harvest cycle after ice falls from the evaporator(s). • Press the power switch and allow the ice to melt. • Use the touchscreen to initiate a manual harvest cycle. Notice Never use anything to force ice from the evaporator. Damage may result. Step 2 Remove all ice from the bin/dispenser.
Step 5 Wait until the cycle is complete, then disconnect power to the ice machine (and dispenser when used). nWarning Disconnect the electric power to the ice machine at the electric service switch box. Step 6 Remove parts for descaling. Please refer to the proper parts removal for your ice machine. Continue with next step when the parts have been removed.
Step 8 Use 1/2 of the descaler/water mixture to clean all components. The solution will foam when it contacts lime scale and mineral deposits; once the foaming stops use a soft-bristle nylon brush, sponge or cloth (NOT a wire brush) to carefully clean the parts. Soak parts for 5 minutes (15 - 20 minutes for heavily scaled parts). Rinse all components with clean water.
Step 12 Replace all removed components. Step 13 Wait 20 minutes. Step 14 Reapply power to the ice machine . Step 15 Press the Clean button and select “Make ice when complete”.

The ice machine will automatically start ice making after the descale cycle is complete (approximately 24 minutes). NOTE: Once the cycle has started it must complete before the ice machine can make ice again.
Removal from Service/Winterization General Special precautions must be taken if the ice machine is to be removed from service for an extended period of time or exposed to ambient temperatures of 32°F (0°C) or below. Notice If water is allowed to remain in the ice machine in freezing temperatures, severe damage to some components could result. Damage of this nature is not covered by the warranty. 1. Turn off the ice machine by pressing the On/Off Button. 2. Turn off the water supply. 3.
Operation Operational Checks GENERAL Manitowoc ice machines are factory-operated and adjusted before shipment. Normally, new installations do not require any adjustment. To ensure proper operation, always follow the Operational Checks: • when starting the ice machine for the first time • after a prolonged out of service period • after cleaning and sanitizing NOTE: Routine adjustments and maintenance procedures are not covered by the warranty.
ICE THICKNESS CHECK The ice thickness probe is factory-set to maintain the ice bridge thickness at 1/8 in. (3 mm). NOTE: Make sure the water curtain/splash shields are in place when performing this check. It prevents water from splashing out of the water trough. Remove the curtain to make an adjustment, then replace immediately after the adjustment is made. 1. Inspect the bridge connecting the cubes. It should be about 1/8 in. (3 mm) thick. 2.
Control Board Timers The control board has the following non-adjustable timers: • The ice machine is locked into the freeze cycle for 6 minutes before a harvest cycle can be initiated. This can be overridden by initiating a manual harvest. Refer to “Manual Harvest” on page 75. • The maximum freeze time is 35 minutes at which time the control board automatically initiates a harvest sequence.
Sequence of Operation QUIETQUBE® MODELS NOTE: The power button must be depressed and the water curtain/ice dampers must be in place on the evaporator before the ice machine will start. INITIAL START-UP OR START-UP AFTER AUTOMATIC SHUT-OFF 1. Water Purge Before the compressor starts, the water pump and water dump solenoid are energized to purge the ice machine of old water. This feature ensures that the ice making cycle starts with fresh water. 2.
FREEZE SEQUENCE 3. Prechill The compressor lowers the temperature of the evaporator(s) before the water pump is energized. The water fill valve will energize and remain on until water completes the water level probe circuit. 4. Freeze The water pump energizes and water flows over the evaporator. After water contacts the water level probe the water fill valve de-energizes. The control board will automatically cycle the water fill valve.
Water Inlet Valve The water inlet valve energized in prechill. After water contacts the low and high water probes the water fill valve de-energizes. Ice builds on the evaporator and the water level drops. When water loses contact with the high water probe, the water fill valve energizes until water contacts the high water probe again. Maximum Fill Time = Prechill fill time + first fill + second fill.
HARVEST SEQUENCE 5. Water Purge The air pump(s) and the harvest valve(s) open at the beginning of the water purge to divert refrigerant gas into the evaporator. The water pump continues to run, and the water dump valve energizes to purge the water in the water trough. CVD Condensing Unit: When the refrigerant pressure is low enough to open the fan cycling pressure control the condenser fan motor stops. 6. Harvest The air pump(s) remain energized and the harvest valve(s) remains open.
AUTOMATIC SHUT-OFF 7. Automatic Shut-Off Ice Machine Section: Shuts off when: • The storage bin is full at the end of a harvest sequence. • The sheet of cubes fails to clear the water curtain and holds it open. • One or both ice dampers are held down. • Bin level probe thermistor senses setpoint (when used). After the water curtain or ice damper are held open for 30 seconds, the ice machine shuts off.

Troubleshooting By Symptom The troubleshooting procedures follow flow charts. There are four symptoms, the symptom that you are experiencing will determine which flow chart to use. The flow chart asks yes and no questions to determine the problem. The flow chart will direct you to a procedure to correct the problem. QuietQube® remote condensing units use separate charts.
RESET TO FACTORY DEFAULTS Before starting troubleshooting procedures, reset the control board to factory defaults to prevent mis-diagnosis. Before resetting to factory defaults do one of the following: A. Copy settings to a usb device and flash settings into the control board when diagnostics are complete. B. Write down any customer settings so they can be re-entered when diagnostics are complete.

DIAGNOSING A CONDENSING UNIT THAT WILL NOT RUN If the ice machine water pump is not energized, refer to “Diagnosing an Ice Machine that Will Not Run.” 1. Verify primary voltage is supplied to the ice machine condensing unit and the fuse/circuit breaker is closed. 2. Verify the high-pressure control is closed. 3. Verify the low-pressure control is closed. 4. Verify voltage is present at terminals 1 & 2 on the compressor time delay relay. 5.
SYMPTOM #2 LOW PRODUCTION, LONG FREEZE CYCLE Ice Machine has a Long Freeze Cycle Ice Formation is Thick or Thin ice fill at Inlet or Outlet of Evaporator or Low Production Information must be verified to eliminate non-refrigeration problems which can cause good refrigeration components to appear defective. Before starting, see “Before Beginning Service” on page 100 for a few questions to ask when talking to the ice machine owner.
Ice Production Check The amount of ice a machine produces directly relates to the operating water and air temperatures. This means a condensing unit with a 70°F (21°C) outdoor ambient temperature and 50°F (10°C) water produces more ice than the same model condensing unit with a 90°F (32°C) outdoor ambient temperature and 70°F (21°C) water. 1. Determine the ice machine operating conditions: Air temp entering condenser: ____° Air temp around ice machine: ____° Water temp entering sump trough: ____° 2.
Weighing the ice is the only 100% accurate check. However, if the ice pattern is normal and the 1/8 in. thickness is maintained, the ice slab weights listed with the 24-Hour Ice Production Charts may be used. 4. Compare the results of step 3 with step 2. Ice production checks that are within 10% of the chart are considered normal. If they match closely, determine if: • Another ice machine is required. • More storage capacity is required.
Installation/Visual Inspection Checklist Inadequate Clearances • Check all clearances on sides, back and top.
Water System Checklist A water-related problem often causes the same symptoms as a refrigeration system component malfunction. Water system problems must be identified and eliminated prior to replacing refrigeration components. Water area (evaporator) is dirty • Clean as needed Water inlet pressure not between 20 and 80 psig (1-5 Bar, 138-552 kPa).
Ice Formation Pattern Evaporator ice formation pattern analysis is helpful in ice machine diagnostics. Analyzing the ice formation pattern alone cannot diagnose an ice machine malfunction. However, when this analysis is used along with Manitowoc’s Freeze Cycle Refrigeration System Operational Analysis Tables, it can help diagnose an ice machine malfunction. Any number of problems can cause improper ice formation.
2. Extremely Thin at Evaporator Outlet There is no ice, or a considerable lack of ice formation, at the outlet of the evaporator. Examples: No ice at all on the outlet half of the evaporator, but ice forms on the inlet half of the evaporator. Or, the ice at the outlet of the evaporator reaches 1/8 in. to initiate a harvest, but the inlet of the evaporator already has 1/2 in. to 1 in. of ice formation. 3.
One Evaporator, Two TXV Models Tubing routing for one evaporator with two TXV’s is different. The evaporator has two inlets and outlets. Fill pattern varies depending on which circuit is affected. Extremely Thin at the Evaporator Outlet will first be visible either 1/4 or 3/4 of the way down the evaporator. Extremely Thin at the Evaporator Inlet will show at the bottom of the evaporator or 1/2 of the way down depending on the circuit affected.
Analyzing Discharge Pressure in the Freeze Cycle 1. Determine the ice machine operating conditions: Air temp. entering condenser ______ Air temp. around ice machine ______ Water temp. entering sump trough ______ 2. Refer to “Cycle Times/24-Hour Ice Production/ Refrigerant Pressure Charts” on page 183 for ice machine being checked. Use the operating conditions determined in step 1 to find the published normal discharge pressures. Freeze Cycle ______ Harvest Cycle ______ 3.
FREEZE CYCLE DISCHARGE PRESSURE HIGH CHECKLIST Improper Installation • Refer to “Installation/Visual Inspection Checklist” on page 103 Air Condenser • Dirty condenser filter • Dirty condenser fins • High inlet air temperature • Condenser discharge air recirculation • Defective “Fan Cycle Control” on page 157) • Defective fan motor • Defective head pressure control valve (Remote) Other • Overcharged • Non-condensible (air) in system • Wrong type of refrigerant • Non-Manitowoc components in s
FREEZE CYCLE DISCHARGE PRESSURE LOW CHECKLIST Improper Installation • Refer to “Installation/Visual Inspection Checklist” on page 103 Condenser • Defective head pressure control valve, won’t bypass page 162 • Defective fan cycle control, stuck closed (page 157) Other • Undercharged • Wrong type of refrigerant • Non-Manitowoc components in system • Liquid line/component restricted 110 Part Number: 000015431 Rev 02 6/20
Analyzing Suction Pressure The suction pressure gradually drops throughout the freeze cycle. The actual suction pressure (and drop rate) changes as the air and water temperature entering the ice machine changes. These variables also determine the freeze cycle times. To analyze and identify the proper suction pressure drop throughout the freeze cycle, compare the published suction pressure to the published freeze cycle time. NOTE: Analyze discharge pressure before analyzing suction pressure.
SUCTION PRESSURE HIGH CHECKLIST Improper Installation • Refer to “Installation/Visual Inspection Checklist” on page 103 Discharge Pressure • Discharge pressure is too high and is affecting suction pressure – refer to ”Analyzing Discharge Pressure in the Freeze Cycle” on page 108 Improper Refrigerant Charge • Overcharged • Wrong type of refrigerant • Non condensible in system Components • Harvest valve leaking • TXV flooding • Defective compressor Other • Non-Manitowoc components in system 112 Part
SUCTION PRESSURE LOW CHECKLIST Improper Installation • Refer to ”Installation/Visual Inspection Checklist” on page 103 Discharge Pressure • Discharge pressure is too low and is affecting low side – refer to “Analyzing Discharge Pressure in the Freeze Cycle” on page 108 Improper Refrigerant Charge • Undercharged • Wrong type of refrigerant Other • Non-Manitowoc components in system • Improper water supply over evaporator – refer to “Water System Checklist” on page 104 • Restricted/plugged liquid line dr
Harvest Valve Analysis Symptoms of a harvest valve remaining partially open during the freeze cycle can be similar to symptoms of either an expansion valve or compressor problem. Use the following procedures to determine if a harvest valve is remaining partially open during the freeze cycle. QUIETQUBE® HARVEST VALVE ANALYSIS The valve can fail in two positions: • Valve will not open in the Harvest cycle. • Valve remains open during the Freeze cycle.
Analyzing Freeze Cycle Suction Line Temperature Suction line temperature alone cannot diagnose an ice machine. However, comparing this temperature during the freeze cycle can help diagnose an ice machine malfunction. The actual temperature of the suction line varies by model, and will change throughout the freeze cycle. This makes documenting the “normal” suction line temperature difficult.
SYMPTOM #3 HARVEST PROBLEMS Normal Ice Cube Melted Out Ice Cube Definition of a harvest problem; At the end of a 7 minute harvest cycle the slab(s) of ice is still contacting the evaporator. The slab of ice may or may not be removable by hand. Harvest problems can be split into two categorizes. • Melted sheet of cubes at the end of the harvest cycle. Ice can be removed rather easily by hand. The back of the cubes are misshapen and melted.
Diagnosing Harvest Issues Follow these steps in order and refer to specific procedures referenced to troubleshoot and diagnose problems. 1. Record the model and serial number of the ice machine and condenser and verify the head section and condensing unit match. 2. Verify the ice formation is normal see page 105 and the bridge thickness is 1/8” at the beginning of the harvest cycle see “Ice Thickness Check” on page 58. 3. Verify power is present at the harvest valve(s) throughout the entire harvest cycle.
5. If the cubes are not melted, confirm the line set outside diameter is correct (see page 33 )the lineset is installed correctly (see page 36) and no kinks exist in the tubing. 6. Record and verify ambient temperature is within guidelines: 118 A. Air temperature entering condenser page 28 B.
7. Refer to chart and record refrigeration operating data. Freeze Data* HP¹ LP² LLT³ HP¹ LP² LLT³ 1 minute after water starts flowing over the evaporator Middle of the freeze cycle End of the freeze cycle Harvest Data* 30 seconds into harvest 2.

CONTROL BOARD RELAY TEST The control board can be set to energize all relays for 3.5 minutes. This allows testing to verify control board relays are closed and line voltage is available for ice machine components - Water pump, dump valve, water inlet valve, harvest valve(s), air compressor(s), contactor/compressor/ fan motor - The fan cycle control must close to energize the fan motor. 1. Press On/Off button to turn off ice machine and navigate in menu to enable all relays.
PROGRAMMING A REPLACEMENT CONTROL BOARD Indigo NXT replacement control boards require the model number to be entered to activate the appropriate look up tables for operation and diagnostic. This can be done two different ways, USB Setup or Manual Setup. USB Setup - Applicable when the control board is operational and has a mechanical issue such as a sticking relay. The asset data is transferred to the replacement control board from the faulty control board.
USB FLASH DRIVE SPECIFICATIONS AND FORMATTING Updating firmware on Indigo NXT model ice machines requires a properly formatted 32 GB or smaller USB flash drive. All USB flash drives must be formatted before use to remove any software programs or files currently on the flash drive. USB Flash Drive Specifications: • USB 2 Version • 32 GB or less capacity • Fat32 File System USB Flash Drive Formatting: Procedure to format a USB flash drive varies with operating system software.
EXPORTING DATA TO A FLASH DRIVE Data can be copied from the control board memory to a flash drive and used to transfer setup and/or cycle data to a replacement control board or to transfer setup information to multiple ice machines. Data may also be requested by service department personnel for analysis or as an aid to troubleshooting. The data files are small and can be attached to an email. Important The flash drive must be formatted before using.
UPGRADING FIRMWARE WITH A FLASH DRIVE Important The flash drive must be formatted before using. All files and software on the flash drive are removed during the formatting process. 1. Drag and drop the files from website or email onto a flash drive, insuring they are not in a folder. 2. Ensure that the ice machine’s power is on. 3. Navigate to USB - Menu / Service / USB. 4. Insert the flash drive into the USB port on the ice machine control board. Do not remove flash drive until update is complete).
MAIN FUSE FUNCTION The control board fuse stops ice machine operation if electrical components fail, causing high amp draw. SPECIFICATIONS The main fuse is 250 Volt, 6.3 amp. nWarning High (line) voltage is applied to the control board (terminals #55 and #56) at all times. Removing the control board fuse or pressing the On/Off button will not remove the power supplied to the control board. CHECK PROCEDURE 1. If control board lights are energized the fuse is good.
BIN SWITCH FUNCTION Movement of the water curtain/ice dampers control bin switch operation. The bin switch has two main functions: 1. Terminating the Harvest cycle and returning the ice machine to the Freeze cycle. This occurs when the bin switch is opened and closed again within 30 seconds during the Harvest cycle. 2. Automatic ice machine shut-off. If the storage bin is full at the end of a Harvest cycle, the sheet of cubes fails to clear the water curtain/ice dampers and holds it open.
Diagnostics SYMPTOMS Bin Switch Fails Open • The ice machine will not start an ice making cycle and the display indicates “Full Bin”. • The ice machine displays “Full Bin Remove Ice” in the clean cycle. Bin Switch Fails Closed • When running a “Long Harvest” alert is displayed and E02 Long Harvest indicated. • May be off on a E02 Long Harvest. • The harvest cycle continues after ice opens and closes the ice damper (harvest cycle is 7 minutes).
DIAGNOSTICS 1. Verify bin switch, curtain/damper and curtain/damper magnet are in place and navigate to inputs. • Menu/Service/Diagnostics/Inputs 2. Open and close the ice damper(s) repeatedly while observing the display and control board lights. A. Curtain switch cycles open/closed - The display indicates open/closed and the control board light energizes/de-energizes - Bin switch is operating normally B.
WATER LEVEL CONTROL CIRCUITRY FUNCTION The water level probe controls the water level by sensing whether water is or is not contacting the water level probe. The water level probe has three sensing probes. Two probes are equal in length and are used to measure conductivity for diagnostics. Factory default settings measure resistance from both long probes to the short probe. SPECIFICATIONS Freeze Cycle Water Level Setting The water level is not adjustable.
PRECHILL & FREEZE CYCLE OPERATION The water inlet valve energizes and de-energizes in conjunction with the water level probe located in the water trough. • The water inlet valve is ON when there is no water in contact with the water level probes. • The water inlet valve turns OFF after water contacts the water level probes for 6 continuous seconds. • The water inlet valve can cycle ON and OFF once in the prechill and up to two times in the freeze cycle.
Diagnostics Important The following occurs when the reverse osmosis (R.O.) option has been enabled and then disabled (i.e. placed back into factory default) and the jumper has not been reset to the 45 second factory default position. A. The higher water level probe sensitivity will remain active see “Reverse Osmosis or Deionized Water Usage” on page 148. B. The control board will generate Water-Level probe faults on every cycle. C. The control board initiates a “Safe-Mode” every other cycle.
3. Disconnect the water level probe wiring harness from the control board and ohm harness and water level probe. Normal readings will show no resistance. White Black Red Short Probe Ohm water Level Probe and Wiring Harness WATER LEVEL PROBE CIRCUIT CHECK AT CONTROL BOARD Wait until prechill cycle starts, then jumper water level probe connections (Red/Black) on the control board. 144 A. Sensing displays and the water stops. Repair wire or replace water level probe. B.
ICE THICKNESS PROBE (INITIATES HARVEST) FUNCTION The ice thickness probe senses ice on the evaporator and signals the control board to start a harvest cycle. SPECIFICATIONS Freeze Time Lock-In Feature The ice machine control system incorporates a 6 minute freeze time lock-in feature. This prevents the ice machine from short cycling in and out of harvest. Maximum Freeze Time The maximum freeze time is 35 minutes at which time the control board automatically initiates a harvest sequence.
Ice Thickness Check The ice thickness probe is factory-set to maintain the ice bridge thickness at 1/8 in. (3 mm). NOTE: Make sure the water curtain/splash shields are in place when performing this check. It prevents water from splashing out of the water trough. Remove the curtain to make an adjustment, then replace immediately after the adjustment is made. Make adjustment only when the ice machine is off to prevent initiating a harvest 1. Inspect the bridge connecting the cubes. It should be about 1/8 in.
Ice Thickness Probe Diagnostics 1. Perform Control Board Self Check and insure the internal ITP circuit passes before proceeding. (Menu/Service/Diagnostics/Control Board/Self Check) • Ice Thickness Circuit: Pass = Continue with step #2. • Ice Thickness Circuit: Fail = Change control board. 2. Remove all ice from the evaporator when present, by initiating a manual harvest in the service menu. 3. Press the power button and turn off the ice machine. 4.
The initial numbers displayed are constantly changing and are less than 3000. With an initial reading of less than 300 and a tap test reading of 3300 or higher indicates a good ice thickness probe and control board. The initial numbers displayed do not change or initial numbers did not increase by 3000 during tap test. • Verify the ice thickness probe connector is properly plugged into the board and the ice thickness probe wiring is correct. If the wiring is incorrect replace the ice thickness probe.
BIN LEVEL PROBE The bin level probe accessory will place the ice machine in a full bin state when ice lowers the temperature to 36° F or less. The touchscreen will display Program Mode On during the full bin state. A lower ice level in dispensers will prevent overfilling or dispense wheel or motor damage. • The bin probe reads actual temperature and must be connected to the T5 terminal on the control board. • The control board recognizes the bin level probe automatically when installed.
Troubleshooting: Refer to normal operation before troubleshooting - The T5 thermistor reading must indicate 36° F or less in the freeze cycle and throughout the harvest cycle to shutoff on full bin at the end of the harvest cycle. View the T5 thermistor temperature on the touch screen (menu/service/diagnostics/temperatures). PROBE SHORTED - TEMPERATURE DISPLAYED IS ABOVE 400° F: A shorted bin level probe wire/thermistor will indicate a temperature higher than 400° F.
THERMISTORS FUNCTION Thermistor resistance values change with temperature. The value supplied to the control board is used to identify temperature at the thermistor location.
Thermistor Matrix Four thermistors are standard on the ice machine. They are labeled T1, T2, T3, T4. Three additional thermistors are available as an option and measure ice bin level, potable water supply temperature and air temperature entering the condenser.
SYMPTOM The alert log indicates a T1, T2, T3, or T4 Fault. CHECK PROCEDURE NOTE: Navigate to Menu/Service/Data/Real Time data/ Time & Temperature NOTE: An open thermistor will display -10°F (-23°C) and a shorted thermistor displays 400°F (204°C). Thermistor Test 1. Disconnect the suspect thermistor from the control board and swap with another thermistor. A. The symptoms move with the thermistor Replace the thermistor. B. The symptom does not change - Perform control board test. Control Board Test 1.

Disconnect/reconnect power to the condensing unit and test for line voltage at terminals 2 & 3.
FAN CYCLE CONTROL FUNCTION Cycles the fan motor on and off to maintain proper operating discharge pressure. The fan cycle control closes on an increase, and opens on a decrease in discharge pressure. SPECIFICATIONS Model CVDF0600 CVDF0900 CVDF1400 CVDF1800 CVDF2100 CVDT1200 Specifications Cut-In (Close) 250 psig ±5 (1723 kPa ±34) (17.23 bar ±.34) 335 psig ±5 2310 kPa ±34 (23.10 bar ±.34) Cut-Out (Open) 200 ±5 (1517 kPa ±34) (15.17 bar ±.34) 275 psig ±5 1896 kPa ±34 (18.96 bar ±.34) CHECK PROCEDURE 1.
HARVEST ASSIST AIR PUMP FUNCTION The air pump helps break the vacuum between the sheet of ice and the evaporator which results in shorter harvest cycles. SPECIFICATIONS 115 Volt or 230 Volt - matches the ice machine voltage. CHECK PROCEDURE 1. The air pump is wired in parallel with the harvest valve - Verify the ice machine is in the harvest cycle and the harvest valve is energized. 2.
COMPRESSOR ELECTRICAL DIAGNOSTICS The compressor does not start or will trip repeatedly on overload. Check Resistance (Ohm) Values NOTE: Compressor windings can have very low ohm values. Use a properly calibrated meter. Perform the resistance test after the compressor cools. The compressor dome should be cool enough to touch (below 120°F/49°C) to assure that the overload is closed and the resistance readings will be accurate. SINGLE PHASE COMPRESSORS 1.
CHECK MOTOR WINDINGS TO GROUND Check continuity between all three terminals and the compressor shell or copper refrigeration line. Scrape metal surface to get good contact. If continuity is present, the compressor windings are grounded and the compressor should be replaced. COMPRESSOR DRAWING LOCKED ROTOR To determine if the compressor is seized, check the amp draw while the compressor is trying to start. The two likely causes of this are a defective starting component or a mechanically seized compressor.
DIAGNOSING START COMPONENTS If the compressor attempts to start, or hums and trips the overload protector, check the start components before replacing the compressor. Capacitor Visual evidence of capacitor failure can include a bulged terminal end or a ruptured membrane. Do not assume a capacitor is good if no visual evidence is present. A good test is to install a known good substitute capacitor. Use a capacitor tester when checking a suspect capacitor.
Refrigeration Components HEAD PRESSURE CONTROL VALVE Manitowoc remote systems require head pressure control valves with special settings. Replace defective head pressure control valves only with “original” Manitowoc replacement parts. Refrigerant Charge Verification The correct amount of refrigerant (name plate charge) is required to operate correctly at all ambient conditions.
Freeze Cycle Operation All Models The head pressure control valve is non adjustable. At ambient temperatures of approximately 70°F (21°C) or above, refrigerant flows through the valve from the condenser to the receiver inlet. At temperatures below this (or at higher temperatures if it is raining), the head pressure control dome’s nitrogen charge closes the condenser port and opens the bypass port from the compressor discharge line.
Diagnostics FREEZE CYCLE - QUIETQUBE® REMOTE CONDENSING UNIT 1. Determine if the coil is clean. 2. Determine the air temperature entering the condenser. 3. Determine if the head pressure is high or low in relationship to the outside temperature. (Refer to the proper “Cycle Times/24-Hour Ice Production/ Refrigerant Pressure Charts” on page 183.) 4. Determine the temperature of the liquid line entering the receiver by feeling it. This line is normally warm; “body temperature.” 5.
Harvest Cycle QUIETQUBE® REMOTE CONDENSING UNIT QuietQube® ice machines may fail in the harvest cycle when the refrigerant charge and ambient temperature create a marginal undercharge of refrigerant. The ice machine may be able to make a full sheet of ice, but fails in the harvest cycle when the receiver runs out of liquid refrigerant. A E02 Long Harvest will result when the ice machine is unable to harvest.
HARVEST CYCLE DIAGNOSTICS QUIETQUBE® REMOTE CONDENSING UNIT The head pressure control valve diverts the compressor discharge gas to the ice machine receiver in the harvest cycle. All refrigerant flow through the condenser in the harvest cycle stops. Symptoms of a head pressure control valve that will not seat 100% closed (completely bypass the condenser) in the harvest cycle are: • Freeze cycle suction and discharge pressure are normal.
Step 3 Details Grasp Here with Hands to Compare Temperatures No Flow R ef w t Flo n a r rige LIQUID LINE FROM CONDENSER HARVEST CYCLE HEAD PRESSURE CONTROL VALVE FAILURE LIST Temperature of the compressor discharge line and liquid line to the ice machine receiver feel the same 30 seconds into the harvest cycle. • The head pressure control valve is functioning correctly. The compressor discharge line is noticeably warmer than the liquid line to the ice machine receiver.
SUCTION ACCUMULATOR OPERATION Liquid refrigerant collects in the suction accumulator during the harvest cycle and is removed during the freeze cycle. The liquid refrigerant is returned to the compressor through a screen and orifice in the suction accumulator J tube. Passing the liquid through the orifice causes a pressure drop; the liquid flashes to a vapor and creates a refrigeration affect. It is normal to see frost on the accumulator, suction line and compressor suction port in the freeze cycle.
Recovery/Evacuation/Charging Procedures QuietQube® Models Do not purge refrigerant to the atmosphere. Capture refrigerant using recovery equipment. Follow the manufacturer’s recommendations. Notice Manitowoc Ice assumes no responsibility for the use of contaminated refrigerant. Damage resulting from the use of contaminated refrigerant is the sole responsibility of the servicing company. Notice Replace the liquid line drier after recovering the refrigerant and before evacuating and recharging.
CONNECTIONS Manifold gauge sets must utilize low loss fittings to comply with U.S. Government rules and regulations. CVD condensing units with reciprocating compressors are manufactured with a check valve in the compressor discharge line. The check valve requires an additional connection on the condensing unit during evacuation or recovery procedures.
RECOVERY/EVACUATION PROCEDURES 1. Press the power button to stop the ice machine and disconnect all power to the ice machine and condensing unit. 2. Install manifold gauges, charging scale, and recovery unit or two-stage vacuum pump. 3. Open high and low side on the manifold gauge set. 4. Perform recovery or evacuation: A. Recovery: Operate the recovery unit as directed by the manufacturer’s instructions. B. Pressure test the system. C. Evacuation prior to recharging: Evacuate to 500 microns.
CHARGING PROCEDURES 1. The ice machine must be off. 2. Close the vacuum pump valve and the low side manifold gauge valve. 3. Open the refrigerant cylinder and add the proper refrigerant charge (shown on nameplate) into the system high side (receiver service valve and discharge line shut-off valve). 4. If the high side does not take the entire charge, close the high side on the manifold gauge set.
System Contamination Clean-Up General This section describes the basic requirements for restoring contaminated systems to reliable service. Notice Routine adjustments and maintenance procedures Manitowoc Ice assumes no responsibility for the use of contaminated refrigerant. Damage resulting from the use of contaminated refrigerant is the sole responsibility of the servicing company.
CONTAMINATION CLEANUP CHART Symptoms/Findings No symptoms or suspicion of contamination Moisture/Air Contamination symptoms Refrigeration system open to atmosphere for longer than 15 minutes Refrigeration test kit and/or acid oil test shows contamination No burnout deposits in open compressor lines Mild Compressor Burnout symptoms Oil appears clean but smells acrid Refrigeration test kit or acid oil test shows harmful acid content No burnout deposits in open compressor lines Severe Compressor Burnout sympt
CLEANUP PROCEDURE Mild System Contamination 1. Replace any failed components. 2. If the compressor is good, change the oil. 3. Replace the liquid line drier. NOTE: If the contamination is from moisture, use heat lamps during evacuation. Position them at the compressor, condenser and evaporator prior to evacuation. Do not position heat lamps too close to plastic components, or they may melt or warp. Important Dry nitrogen is recommended for this procedure. This will prevent refrigerant release. 4.
Severe System Contamination 1. Remove the refrigerant charge. 2. Remove the compressor and inspect the refrigeration lines. If burnout deposits are found, install a new harvest valve and TXV. 3. Wipe away any burnout deposits from suction and discharge lines at compressor. 4. Sweep through the open system with dry nitrogen. Important Refrigerant sweeps are not recommended, as they release refrigerant into the atmosphere. 5. Install a new compressor and new start components. 6.
9. Follow the normal evacuation procedure, except replace the evacuation step with the following: A. Pull vacuum to 1000 microns. Break the vacuum with dry nitrogen and sweep the system. Pressurize to a minimum of 5 psig (35 kPa, .35 bar). B. Change the vacuum pump oil. C. Pull vacuum to 500 microns. Break the vacuum with dry nitrogen and sweep the system. Pressurize to a minimum of 5 psig (35 kPa, .35 bar). D. Change the vacuum pump oil. E. Pull vacuum to 500 microns.
LIQUID LINE FILTER-DRIERS The filter-driers used on Manitowoc ice machines are manufactured to Manitowoc specifications. A Manitowoc drier has dirt-retaining filtration, with fiberglass filters on both the inlet and outlet ends. This is very important because ice machines have a back-flushing action that takes place during every Harvest cycle. The size of the filter-drier is important. The refrigerant charge is critical.
REPLACING PRESSURE CONTROLS WITHOUT REMOVING REFRIGERANT CHARGE This procedure reduces repair time and cost. Use it when any of the following components require replacement, and the refrigeration system is operational and leak-free. • Fan cycle control • High pressure cut-out control • Low Pressure cut-out control • High side service valve • Low side service valve Important This is a required in-warranty repair procedure. 1. Disconnect power to the ice machine. 2.
