If water-cooled, are inlet and drain connections to condenser correct to prevent “water hammer”? Are drain lines separate and vented? Is there 6I clearance on all sides and top for proper air circulation? Does the water curtain move freely, and does the float valve shut off incoming water to the water pan? START-UP AND CHECK OUT 1.
OWNER -OPERATOR The installation is not complete until you are sure the owner-operator understands the cuber operation and his or her responsibility of preventative maintenance. Does the owner-operator know: 1. Location of electrical disconnect switch and water shut-off valves? 2. How to start and/or shut down the product, clean and sanitize it? 3. Bin full operation and reset operation of high pressure cutout (water-cooled and remote products only)? 4. How to clean the condenser and fan blade? 5.
Power Switch SANITIZING PROCEDURES NOTE: To be performed only after cleaning the ice machine: 1. Add 1/4 ounce (7.08 g) sodium hypochlorite solution (common liquid laundry bleach) to the water pan and allow the pump to circulate the solution for 5 minutes. You may also use a commercial sanitizer such as Calgon Ice Machine Sanitizer following the directions on the product label. 2. Turn the Cuber power switch off and depress and hold the dump switch to drain the water pan. 3.
4. You have the option of selecting dump cycle intervals of: S every cycle; (Standard setting from factory) S every 3rd cycle; S every 5th cycle; S every 7th cycle. Remember, the higher the mineral content in the water supply the more often it will be required to dump the water and/or clean the product if proper water treatment is not used. DĆ13 YL RH Evap.

ADJUSTING BRIDGE THICKNESS TOP ROW 3/8I - 5/8I DIMPLE CENTER 1/8I BRIDGE For optimum ice production and maximum cube separation, the ice connecting the individual cubes should be a minimum of 1/8I (.32cm) thick at the center area of the ice waffle. BRIDGE 1/8I (0.32 cm) It is normal for the ice slab to be slightly thicker at the bottom and taper off in a slight wedge pattern at the top. The top row of cubes must have a complete pattern of ice on all four sides and the back wall.

CIRCUIT BOARD DIAGNOSTIC PROCEDURE Turn the power switch to the “ON” position. The D-5 red LED (error indicator) will be illuminated for 2 seconds. After the D-5 red LED goes out, short across the bottom two terminals of the Test Plug with a jumper wire or a pocket screwdriver and then remove the jumper. The circuit board is now in the test mode. One of these two conditions will exist: S If the Ice Thickness Potentiometer is within the factory setting the D-5, red LED will flash continiously.
RESTORING ICE THICKNESS POTENTIOMETER TO FACTORY SETTING 1. Turn cuber power switch to the OFF (center) position. 2. Unplug the proximity switch(es) and the thermistor(s) from the circuit board. 3. Turn the cuber power switch to the ON position. The red LED D-5 will illuminate for 2 seconds and then go out. 4. Short across the bottom 2 pins of the Test Plug using a wire jumper or a pocket screwdriver. Immediately remove the jumper.
COMPONENT FUNCTION (CIRCUIT BOARD ETC.) TEST PLUG Board manufactures check point. DO NOT ATTEMPT ANY VOLTAGE CHECKS AT THESE PINS. SENSORS Condenser sensor (WHITE) and suction line sensor (BROWN) are thermistors rated 1k ohm at room temperature. S Condenser sensor signals the circuit board for fan cycling and also serves as the high temperature safety shut down. The red “Error LED” will flash on and off every second, during high temperature safety shut down. Product is functionally shut down.
VOLTAGE SELECTOR SWITCH 1. Selector bar in center position, switch is open. Product is inoperative. 2. Selector bar in down position, selection is for 115 VAC. 3. Selector bar in up position, selection is for 230 VAC. STACKING CABLE When stacking the “I” series cuber the connecting cable (connecting the two (2) circuit boards) will allow: the bottom Unit to shut off on the full bin signal (or any error code), the top Unit will then finish the cycle it is in and shut down.
2. 3. 4. 5. Water supply to the product is correct and flow over the evaporator is correct. Cuber refrigerant charge is correct. TXV sensing bulb is properly located and secured to the suction line and correctly insulated. Hot gas valve(s) are not leaking and/or seeping through. Starving TXV - Product Symptoms 1. Suction pressure lower than normal for the operating conditions. 2. Ice production lower than normal and/or none. 3. Ice pattern on evaporator (if any) thin at top and thick at bottom.
SERVICE STEM VALVES When closing the service stem valves to remove your gauge and manifold set always close the high side stem valve first. Following this procedure will allow the system to “PULL” the refrigerant vapor from your manifold set to reduce refrigerant loss. When the pressure has been reduced, close the low side stem valve.
Check for supply voltage from circuit board, lead connections to contactor coil, and ohms value of coil. * (3) if the product is 3 phase Note: See compressor run-on condition check procedure on page 31. COMPRESSOR & STARTING COMPONENT CHECK-OUT PROCEDURE When compressors fail to start or run properly, it is normally the external electrical supply or the compressor start components that are defective – the overload protector, start and/or run capacitor, relay, circuit board, safety controls, etc. 1.
2. To check the compressor motor for accidental ground, perform a continuity check between terminals C, R and S to the compressor shell or a copper line of the refrigeration system (do not use a painted surface). Continuity present, the compressor windings are grounded and the compressor must be replaced. If the compressor starts, but trips repeatedly on the overload protector, remember that the overload is both temperature and current activated.
A good vacuum is not always easy to measure, however the goal is to have less then 1% non-condensible vapors in the system at the completion of the evacuation. Basic guidelines with a good pump would be to evacuate a selfcontained product 30 to 45 minutes and a remote product no less than 60 minutes. The system should be evacuated to approximately 200/250 microns. Then perform a 5 minute holding test. You may expect a low grade loss of the vacuum as normal.
Chemical analysis is the key requirement to the definition of “Reclaim”. Regardless of the purity levels reached by a re-processing method, the refrigerant is not “reclaimed” unless it has been chemically analyzed and meets ARI Standard. HIGH PRESSURE SAFETY SWITCH All water-cooled and remote products contain a high pressure safety cut-out switch. The function of this switch is to shut down the cuber should excessive pressure develop in the high side of the refrigeration system.

INSTALLATION INSTRUCTIONS REMOTE CONDENSERS 1/4-20 SCREW UNIT LEG BRACE LEG 1. Follow the standard installation instructions supplied with cuber. Do not hook cuber into the power source until the remote condenser and line set installation is complete. 2. Assembly of remote condenser (see drawing): A. Assemble legs to base panel. Install leg supports on legs. B. Locate the remote condenser in a well–ventilated area on the roof away from other refrigeration equipment’s condenser discharge air flow. C.
F. NOTE: The condenser fan may cycle off during the harvest cycle – this would be normal. Installing an IMI Cornelius remote cuber with other than an IMI Cornelius remote condenser and line set may be reason to void the cuber warranty. LIQUID REFRIGERANT LINE DISCHARGE LINE CORRECT 4. Each condenser and cuber is connected with two (2) *pre-charged lines. A. The pre-charged lines are ordered separately from the condenser to suit each individual application. B.
REMOTE CONDENSER LOCATION 1. Physical Line-Set Length: 55 Ft. Maximum [16.764 meters] The ice machine compressor must have the proper oil return. Line-set rises, drop, or horizontal runs greater than the maximum distance allowed will exceed the compressor start-up and pumping design limits, and will result in poor oil return to the compressor. Line-Set Rise: 35 Ft. Maximum [10.66 meters] Line-Set Drop: 15 Ft. Maximum [4.57 meters] 2. Calculated Line-Set Distance: 100 Ft. [30.
COMBINATION OF DROP(S) WITH HORIZONTAL H D AIR FLOW c. d. Insert measured horizontal distance into formula. No calculation is necessary. (6 ft.) [1.828 meters]. Add the calculated rise, calculated drop, and horizontal distance together to get the total calculated distance (25.5 + 52.8 + 6) equals 84.3 ft. [25.694 meters]. If 100 ft. [30.48 meters] total calculated distance is exceeded, the condenser must be moved to a new location which permits proper equipment operation.
E. Check all fittings for leaks. 5. Final Installation: A. Remove grill from the right-hand side panel of cuber. B. Turn service port on receiver tank to open position releasing refrigerant to the balance of the system. C. Leak check line-set connections at cuber and condenser. D. Replace grill. E. Connect cuber to power source. F. Make sure electrical connections follow all local and national codes. 6. Start Up: A. Use standard procedures from cuber installation instructions. B.

HEAD PRESSURE CONTROL [HEADMASTER] receiver receiver discharge discharge condenser condenser above 70°F normal below 70°F by-pass The Cornelius “I” series remote systems use an Alco Head Pressure Control, normally referred to as a headmaster. This control is mounted in the remote condenser with a fan cycling control switch. Using both these controls gives the system positive operation under a wide range of condensing temperatures.
REMOTE SYSTEM EVACUATION/RE-CHARGE All field repairs to the sealed system must start with a total discharge of the system following the requirements of the Clean Air Act of July, 1992. Proper evacuation of the total remote system will require a three (3) point hook-up of your manifold and hose set, (see drawing): Point #1 - Cuber receiver outlet valve Point #2 - Cuber high side service valve Point #3 - Cuber low side service valve Evacuation: 1.
