LINE SET INSTALLATION A universal line set adapter kit, part number OS-QUICK, is available if you need to field engineer your line set. Both lines should be insulated separately the entire length of run. The refrigerant charge for a new unit is distributed between the unit head and the URC condenser. The line set has a minimal holding charge of 15 to 30 psig refrigerant vapor. If you need to field engineer your line set or shorten/ lengthen a precharged line set you can do so by following these steps: 1.
SYSTEM CHARGE - R-404A The ice machine head and URC condenser are shipped with enough refrigerant charge for up to 66 feet of line set length. The maximum line set length is 100 equivalent feet from the head to the condenser. For applications longer than 66 ft. up to the maximum 100 ft. Length, additional refrigerant must be added. For units utilizing 1/4" L.L. and 3/8" D.L., the line size should be increased to 3/8"L.L. and 1/2"D.L. for the entire length of the run. Add 16.5 ounces plus 0.4 oz.

“E” Control Board Functions An instruction label explaining the “E” board features is included somewhere on the unit. You should find it either on the control box cover, on the inside of the front panel, or under the top panel. A stick on label is also included with the service replacement board. If you are replacing an “E” board, be sure to place the new label over the original label.
ATTENTION ! THIS UNIT HAS A CONTROL PRODUCTS IMPROVED “E” CONTROL BOARD INSTALLED. HOSHIZAKI PART NUMBER 2A1410-01. The improved “E” board includes LED lights and audible alarm safeties. The red LED indicates proper control voltage and will remain on unless a control voltage problem occurs. At startup a 5 second delay occurs while the board conducts an internal timer check. A short beep occurs when the power switch is turned “ON” or “OFF”.
MANUAL RESET SAFETIES: The Alpine control board has one manual reset safety. It is the 127°F high evaporator temperature safety. There is no indication that the Alpine board is off on this safety. You will only notice that the unit will restart in the 1 minute fill cycle when the power switch is shut OFF and Back ON. This is the only way to reset this safety. If this occurs check for a hot gas circuit or valve problem, a headmaster stuck in bypass, hot water entering the unit, or a shorted thermistor.

HEAD PRESSURE CONTROLS WATER-COOLED An adjustable (Pressure Modulated) water-regulating valve is installed on the water-cooled condenser outlet. A # V46 Johnson Controls Penn valve is used. A label on the valve housing identifies the Penn valve. PENN VALVE Adjust: CW - for lower pressure and outlet water temperature with higher water flow. CCW – for higher pressure and outlet water pressure with lower water flow. CONDENSER OUTLET WATER TEMPERATURE RANGE.
REMOTE HEAD PRESSURE CONTROL All remote condenser units utilize a condensing pressure regulating (CPR/Headmaster) valve to maintain head pressure in low ambient conditions. You will find a Sporland LAC-4 210 psig. valve mounted in the condenser of all R-404A remote units with the exception of the KM-2400SRF3. The KM2400SRF3 model uses a Sporland LAC-5 210 psig valve which is mounted in the unit head. D R The symptoms of a bad headmaster are similar to an undercharged unit.

bracket. When installing, make sure the bracket points downward so that the cubes will easily fall away from the bin control bulb. ___ When replacing a thermostatic bin control, check the operation by holding ice against the thermostatic bulb with the control switch in the wash position. The pump should stop within 6 to 10 seconds. Adjustment up to 30~45 seconds could be acceptable depending on the application. Adjust the control “CCW” for a faster shut down.
a) When the control paddle is hanging in the normal position, the resistance at the red K4 connector will be 7.9 K ohms and the unit will start. BIN EMPTY Priximity switch closed. Mechanical control in the normal position supplies 7.9 K ohms at red K4 connector to start unit. b) When the unit is held to the right, the resistance at the K4 red connector will be 15.
inch of the sensor. It also connects to the K4 red connector on the control board and has the same operating sequence as the mechanicam bin control. The capacitive proximity control has 4 components including a sensor, bin control relay, 24VDC power supply and resistor harness. This resistor harness is slightly different from the harness used for the mechanical control. It will supply either 15.8 K ohms or 5.6 K ohms to the red K4 connector to control the unit.
HOSHIZAKI KM CUBER SEQUENCE OF OPERATION THE STEPS IN THE SEQUENCE ARE AS FOLLOWS: NOTE: When power is supplied to the “E” Control board, a 5 second delay occurs at start-up. 1. 1 Minute Fill Cycle The unit always starts in the 1 minute fill cycle. When power is applied to the unit the water valve is energized and the fill period begins. After 1 minute the board checks for a closed float switch. If the float switch is closed the harvest cycle begins.
4. Harvest Pump Out When the float switch opens and signals the completion of the freeze cycle, the harvest cycle begins. The hot gas valve opens and the compressor continues to run. The drain timer starts counting the 10/20 second pump out. The water pump stops for 2 seconds and reverses, taking water from the bottom of the sump and forcing pressure against the check valve seat allowing water to go through the check valve and down the drain.
12/01/02 12/20/03 2/20/03
KM CHECK OUT PROCEDURE The following is a detailed explanation of the KM 10 Minute Check Out procedure. The 10 minute check out procedure is basically a sequence check which can be used at unit start-up or for system diagnosis. Using this check out procedure will allow you to diagnose electrical system and component failures in approximately 10 minutes under normal operating conditions of 70°F or warmer air and 50°F or warmer water temperatures.
not starting freeze cycle, check defrost completion timer adjustment, thermistor for open circuit, discharge line temperature, C efficiency, and if HGV is fully open. C) Freeze cycle – C remains energized, PM, (LV on RS model), and FM energize…WV & HGV de-energize. Unit is held in freeze by 5 minute short cycle protection timer. After 5 minutes freeze cycle operation to transferred to FS for freeze termination. During first 5 minutes of freeze, confirm that evaporator temperature drops.
RESERVOIR FLUSH SYSTEM A displacement device ( cap or assembly ) is positioned over the top of the overflow stand pipe. This device allows sediment to be pulled from the bottom of the reservoir and flush down the drain when overflow occurs. Water should always overflow the stand pipe for a short period towards the end of harvest to allow this flushing action. To extend this flushing action, adjust dip switches 1 & 2 for longer harvest.
The service switch also has three positions, “DRAINCIRCULATE-WASH”. With the control switch in SERVICE and the service switch in DRAIN, the pump starts and drain valve solenoid opens to automatically drain the reservoir. In the CIRCULATE position, the pump motor circulates cleaner to the outside of the evaporator. In WASH, the cleaning solenoid energizes and the pump circulates cleaner to the inside and outside of the evaporator.
12/01/02 2/20/03 4A2817-01 If fuse blows, look for shorted component before replacing.
COMPONENT CHECKS: 1.FLOAT SWITCH: Check out the float switch with an ohm meter. When the float is up, the switch is closed. When the float is down, the switch is open. STICKING FLOAT SWITCH: It is important to remember that the float switch is in the water circuit and is susceptible to scale buildup. This can cause the float to stick either up or down. If the float switch is sticking, it should be cleaned thoroughly with ice machine cleaner and checked for proper operation.
UNIVERSAL REPLACEMENT FLOAT SWITCH: There are two styles of KM float switches. One has no hole in the outside pipe and one has a hole in the outside pipe. Float switch number 4A0886-02 can be used as a universal replacement on any KM unit. Simply seal off the small hole in the outside tube with silicone or a seal cap from 3/8” refrigeration tubing if it is not needed. CONNECTOR BOOT: The float switch boot will sometimes collect scale deposits since it is in a low area of the water circuit.
Note: The Thermistor must be mounted using a heat sink compound to assure good heat transfer and accurate sensing. Use Hoshizaki Part Number 4AO68301 or equivalent. (Radio Shack #276-1372 or GE Electronics #10-8108, ect.) 3. CONTROL BOARD: The electronic control board maintains the sequence of operation. There are 3 input connections to the board. 1. The Float switch connects to the control board through the black K5 connector. 2. The thermistor connects to the control board through the white K3 connector.
2. Turn the control switch to ICE and check for proper control voltage. If the Red LED is ON, the control voltage is good. If the Red LED is OFF, check the control transformer circuit. See checking control transformer. 3. Next, check the 115 volt input at the 10-pin connector. Check the brown wire at pin #10 to a white neutral wire for 115 volts. (Always choose a white neutral wire to establish a good neutral connection when checking voltages.) A jumper also feeds 115 volts into pin # 7.
4. BIN CONTROL: Checkout for the bin control will vary depending on the model and control that is used. a) THERMOSTATIC BIN CONTROL: The thermostatic bulb is mounted in the ice drop area to sense the ice buildup. To adjust the bin control, hold ice against the bulb while the unit is operating. You will find it easier to place the control switch to the wash position to check the bin control operation. It is easy to hear the pump motor stop when the bin control opens.
closes a magnetic proximity switch. The control is connected to the red K5 connector on the control board through a resistor harness. As the proximity switch opens or closes, the resistance will change to signal the control board to start up or shut down. The control board will only respond to this change in resistance during the first 5 minutes of each freeze cycle. Note: Dip switch # 7 must be in the ON position for this control.
CHECKOUT: To check the operation of this control follow the same check out procedure as with the mechanical control. Instead of moving a paddle, you will place your hand within 1/2~1 inch of the sensor end. With the control switch in ICE, you should hear the bin control relay switch when you move your hand away from the sensor end and back again. Check the resistance supplied at the Red K4 connector as you move your hand back and forth at the sensor end.
The sensor has two LED lamps that light to show that power is supplied. Since the voltage is DC, the sensor is polarity sensitive. The sensor has four wires. The orange wire is capped off and not used. The black wire connects to the coil of relay X7. The brown wire is the positive lead and connects to terminal J2-1 on the power supply. The blue wire is the negative lead and connects to terminal J22. If these wires are crossed, the sensor will not shut the unit down.
6. KM PUMP MOTOR ASSEMBLY: The KM pump assembly has a dual winding PSC motor with an internal overload. The motor has a cast housing and sealed stainless steel roller bearings. No lubrication is required for these roller bearings. If the pump motor fails, always repalce the pump motor capacitor. If other failures occur, the front end of the pump assembly is rebuildable. The mechanical seal is the most common failure part and can be replaced.

7. INLET WATER VALVE: Hoshizaki uses inlet water valve solenoid to fill the reservoir for ice making. This constant duty solenoid valve is very reliable however, in areas of hard water and high levels of chlorine, the diaphragm is susceptible to failure. Water quality is constantly changing and local municipalities are now adding higher levels of chlorine, chloramine, and chlorine dioxides to the water. These agents can damage rubber parts and effect the diaphragm life.
Because of the different flow rates, it is important to use the correct OEM water valve when servicing a Hoshizaki ice maker. Use the following chart to identify the correct valve, diaphragm or inlet screen.
Diagnosing water problems. Many common water related problems will cause cubes to look unnatural. Looking at the ice in the bin will point you towards the problem area. Study these shapes and causes to help you diagnose water related problems. 1. Normal cube, No problem. Average cube size 1/2” thick x 1 1/8” wide x 1 1/2” high. 2. Larger than normal cube with heavy saddled edges. Note: Normal cube may have slight saddled edge.
3. Bridging or ice strips a) Bridging that occurs on all ribs of all evaporator plates is the result of excessive water in the reservoir. This is caused by the inlet water valve leaking by. Check for a plugged bleed port in the water valve diaphragm or a defective water valve. b) May be the result of # 2. c) Bridging can occur on a few ribs if some of the holes in the water distribution tubes are plugged.
4. Melt away of back of cube a) This can occur if the evaporator plate is scaled up. De-scaling is required. b) Insufficient water flow during harvest can also cause the flat side of the cube to melt away. Check for a plugged inlet water valve screen, plugged external filter, low water pressure, or a small water line size. EITHER OR BOTH OF THESE ITEMS CAN CAUSE THIS SYMPTOM. 5. Small cube (Size will depend on how much water is in the reservoir.) a) b) c) 6.

PREVENTATIVE MAINTENENCE: Perventative Maintenance is the key to long equipment life and maximum efficiency. Hoshizaki recommends preforming the following maintenance steps at least annually. The PM frequency will depend on the local water quality and operating conditions. PREVENTATIVE MAINTENANCE STEPS: 1. Clean the removable air filter. Hoshizaki air-cooled units include a front accessible, cleanable air filter. This filter collects dirt, dust, and grease can be cleaned with warm soapy water.
CLEANING/SANITIZING PROCEDURE A label which details the step by step cleaning/sanitizing procedure is located on the inside front panel of the ice machine. These instructions are also provided in the Instruction Manual shipped with each unit. Follow these instructions to conduct a thorough cleaning and sanitizing of the water system. Annual cleanings are recommended. More frequent cleanings may be required in bad water areas.

12/01/02 12/20/03 2/20/03 MECHANICAL BIN CONTOL OPERATION: The mechanical bin control is included on some modelsproduced in 2002. The mechanical assembly is located in the ice drop zone area . When the actuator paddle is in the normal (Bin Empty) position, the bin control proximity switch will close. 1. When the switch contacts close, 7.6 K Ohms of resistance is supplied to the K4 board connector.
12/01/02 12/20/03 2/20/03 24 VDC CAPACITIVE PROXIMITY BIN CONTROL: (Used on KM-1300NRF/H only) The capacitive bin control requires DC voltage to operate. It has a seperate 24VDC power supply and switches a control relay to supply resistance to the K4 connector. The relay contacts isolates the 24VDC from the control board which switches by resistance. 1. When the bin is empty, the resistance at K4 is 5.6 K Ohms. 2. When ice is within 1/2 to 1 inch of the sensor end, the resistance at K4 is 15.

FLAKER/DCM INSTALLATION - GENERAL As always, you should follow the installation instructions that are provided in the instruction manual supplied with the unit. You will also find a yellow instruction sheet attached to the top of a new unit. This sheet highlights the installation steps. Three things are critical for a proper F/ DCM installation: 1. The water temperature should fall within the 45° F to 90° F range.
INTERNAL AUGER DESIGN Hoshizaki Flakers and DCM’s use an internal auger system to provide high quality crisp flakes and cubelet ice. The evaporator cylinder and auger are made of anti-magnetic stainless steel. This higher quality stainless steel elimnates pitting caused by harmful minerals in the water. This maintains a smooth surface to reduce ristriction to ice flow providing consistant production and quality. The picture below is a generic breakdown of the F/DCM evaporator assembly.
COMPONENT TECHNICAL DATA CONTROL TRANSFORMER Hoshizaki Flaker units include a 24 volt control transformer. This transformer has a 115 volt primary and 24 volt secondary and is protected by a 1Amp control fuse. (The DCM has a dual output secondary of 10.5/24V) The 24 volt secondary supplies power to the solid state timer board, relay coils, inlet water valve and flush timer circuit. The flush valve will be either 24 volts AC or DC, depending on the model.
F-1000M GEAR MOTOR CHECKOUT NORMAL AMPERAGE: The amperage for the F-1000M gear motor should be 0.6~1.0 amps with no load and 1.0~1.4 amps when making ice. Answer the following questions to discover the possible cause for your failure: 1. Is Ambient Temperature above 45 degrees F. 2. Does the unit have the Wrong Extruding Head. Check the Extruder Type. Is it a Flaker or Cubelet style. (The cubelet style head will have smaller openings for the ice to extrude.) 3. Does the unit have the Wrong Cutter.
Although it is common practice to install a larger fuse during service diagnosis, you should not leave a larger fuse in the unit when you leave the site. This could cause a serious unit failure. 3. MISWIRING Is gear motor wired correctly and wire connections tight. Check the wiring diagram for the proper wiring. 4. BIN CONTROL SWITCH DOES NOT OPERATE Check the bin control operation. A bad or miswired bin control can cause ice to back up in the spout and chute and cause higher gear motor amperage.
and clean the cylinder wall with a Scotchbrite pad & cleaner. The extruding head surface may also have heavy scale and can be cleaned with Scotchbrite & cleaner as well. AUGER BEARINGS: Bearing Type: Sleeve/Alignment, Bearing Material: Poly/Carbon The bearings are pressed into the top extruding head and lower brass housing. A repress program is available through the local Hoshizaki Distributor for undamaged extruding heads and housings. The bearings should always be replaced as a set.
AUGER INSPECTION / BEARING REPLACEMENT A visual inspection of the auger bearing shaft surface is also recommended annually in poor water areas. The steps for this inspection is as follows: Note: Clean the evaporator prior to removing the auger. This will loosen scale around the extruding head and allow for easier removal. (1) Follow steps 1 through 5 of the bearing inspection procedure above. (2) Remove the (metric) Allen head cap screws that secure the extruding head in place.
and off of the housing. Holding the evaporator up, re-tighten the belly band. This will hold the evaporator up so that you can remove the housing. (8) Remove the bolts that secure the housing to the gear motor assembly and remove the brass housing. The mechanical seal ceramic disk and boot are pressed into the top of the housing. Remove these parts before you exchange the bearings. The extruding head and brass housing will be exchanged for a repressed set at your local distributor.
is included in the motor windings. Both will work in conjunction with the protect relay to shut the unit down. 4. Voltage protect relay: This relay will shut the unit off in case of a voltage surge and automatically restart the unit when the voltage is correct. 5. High pressure switch: All Hoshizaki ice machines include an automatic reset high pressure safety switch to shut down the unit in case of high head pressures. 6. Fuse protection: A lamp buss-type fuse is utilized in the control circuit.
the switch shaft can cause the floats to stick. This will effect the unit operation. In this case, the float switch should be cleaned and checked. The float switch is held in place on the top cover by a twist lock bracket. To remove it, twist the switch flange and lift. Soak the switch assembly in ice machine cleaner. While it is not necessary to do so, some technicians remove the floats from the shaft during cleaning. If you remove them, note that the blue float is on top.
FLAKER WATER FILL SYSTEM The reservoir in a Hoshizaki auger type ice maker feeds water by gravity flow to the evaporator cylinder. The level of water in the reservoir is maintained by the operation of the dual float switch. The dual float switch assembly is made up of two reed switches inside of a sealed shaft. The reed switch contacts are operated by individual magnets attached inside of the two separate floats.
FLAKER TIMER BOARD The solid state timer board used in Hoshizaki Flakers is a simple electronic sequence timer. In order for the board to sequence, certain circuits must be closed. In order to diagnose a bad timer board, it is necessary to check these circuits to assure they are operating properly. If you are trouble-shooting a timer, the first thing you should check is the in coming control voltage. All Hoshizaki flakers have a 24 volt control transformer.
Flaker Sequence of Operation The Hoshizaki Flaker utilizes a solid state sequence timer board to switch the components on and off as needed. The sequence is as follows: With proper voltage and water supplied to the Flaker and the flush and ice switch is in the ice position, power is supplied to the inlet water valve. The unit will not start unless the reservoir is full and both floats on the dual float switch are closed (in the up position). The operation is then turned over to the bin control.
12/01/02 12/20/03 2/20/03
FLAKER PERIODIC FLUSH Beginning with the F-450M and larger flakers, a periodic flush cycle is included. A 12 hour timer will cycle the unit down and open the flush valve which allows the complete water system to drain. The unit will remain off for 20 minutes which allows any ice remaining in the evaporator to melt and flush the evaporator walls and mechanical seal out. The inlet water valve is not energized during this flush period. The unit will automatically restart after 20 minutes on the flush timer.
