Each ice maker and each ice bin must enter the drain stack through separate connections.
Models equipped with a liquid condenser that does not recirculate coolant must have a drain for each condenser that enters the drain stack through separate connections
The drain hose or pipe will remain a constant diameter from the machine to the drain
o
The building drain must be able to accommodate all the drain water from the ice
machine operation.
Individual drains will not be directly connected to a common manifold, drain or standpipe. If
individual drains are to be discharged into a common manifold, drain or standpipe, a minimum 38mm (1.5”) air gap must be provided at each connection. This is to prevent any backflow of drain water into the ice maker or ice bin.
Drain lines will be installed with a minimum drop of 1” per 3’ run (2.5cm per meter run).
The temperatures of the water supply fall between 45°F (7°C) and 90°F(32°C)
The water supply must be potable, not laden with sediment and have free chlorine levels no
greater than 0.2ppm.
A minimum 5 psig (0.034 MPa) dynamic water supply pressure is required for proper
operation of the ice maker water valve. Please note that on liquid cooled ice machines, where the same water supply is used for both condenser cooling and the potable water supply, the demand for condenser coolant may cause the supply pressure to drop. This is most notable at the time of peak load, at the beginning of the freeze cycle. The maximum water supply pressure is 100 psig (0.6 MPa).
All water lines have been purged before connection.
All KOLD-DRAFT models are intended to be installed with a permanent connection to the field
electrical supply. Drop cord connections are not to be used with this equipment. Always be sure the power supply is the same as the ice machine’s electrical specification, which is listed on the serial number tag on the front of the top frame cross member
Each ice maker must be connected to the grid through its own dedicated fuse or HACR type
circuit breaker.
Each ice maker must be connected to a separate protected circuit with no other loads.
Fused disconnects, installed adjacent to each ice maker, are recommended and may be
required by local codes. These components must be supplied by the installer.

DANGER:
Failure to comply with these regulations may cause serious injury or death
Water Treatment:
Electrical service must fall within the voltage tolerances listed below:
Nominal (V) No-Load Maximum
115 (1 Series) 126 104
208-230 (4 and 5 Series) 250 198
230 (7 Series) 250 210
220/380 (8 Series) 420/3 phase 210/1 phase
Breaker or fuse service must be no greater than the maximum rating as specified on the
rating label attached to the back of the machine.
The minimum circuit ampacity listed on the back of the machine does not indicate a typical
running current value. Use the minimum ampacity value for sizing branch circuit conductors up to 26 feet (8 meters) in length. For a conductor length over this length, increase the wire gauge as required by code.
and cause damage to the machine and its surroundings.
Warning:
that the ice making supply water is potable and not laden with sediment. The use of additional water treatment may facilitate or reduce the frequency of the need for cleaning. Please consult your local water conditioning supplier for specific
recommendations.
Note:
Ambient temperatures higher than the maximum specification will result in reduced
capacities and high system pressures in air-cooled models. Temperatures lower than the minimum will cause the machine to malfunction due to an inability to eject the ice from the evaporator. Ambient temperatures less than 60°F (15 °C) may cause the bin thermostat to malfunction.
Clearance must be provided for ventilation and access for service. Ventilation is
especially important for models with air-cooled condensers. Failure to provide adequate clearance may result in reduced capacities and high system pressures.
Ice machine drains and bin drains may be insulated to prevent condensation.
The use of water treatment may increase the intervals between cleaning operations and
the overall machine life.
If a water pressure regulator is used, the recommended setting is 30 to 50 psig (0.2 MPa
to 0.3 MPa) dynamic.
Do not connect the ice machine to a hot water supply line. Insulate the water line from
sources of heat for greater operating efficiency. Supply water temperatures higher than the recommended maximum will cause reduced capacities.
Normal protector size is based on rated voltage and operation at lower than extreme
temperature limits. Branch circuit conductors may be sized to allow increasing the protector value up to the specified maximum. This may avoid nuisance protector opening under harsh operating conditions.
There are no specific requirements for water treatment provided

Additional Pre-install Information for Cooling Tower Applications (L models)
The ice machine does not need to be modified for use with a cooling tower provided the cooling tower is properly designed for the application. Information regarding the amount of heat rejection, as well as the pressure drop through the condenser and liquid valves is required to properly select or design a cooling tower application for an ice machine.
Coolant entering the condenser must not exceed 90°F (32.2°C). Coolant exiting the condenser must not exceed 110°F (43.3°C). Allow for a pressure drop of 7 psi (48 kPa) between the liquid coolant inlet and outlet of the
condenser. The condenser liquid control valve will regulate the flow of coolant through the condenser,
thereby controlling the high side pressure in the ice machine.

ASSEMBLY
Unpacking
Unpacking a KOLD-DRAFT machine can be done by prying off the boards that are holding the cardboard box to the shipping pallet. The box can then be lifted vertically to expose the machine. Tools to complete this job would include a claw hammer or some other form of pry-bar.
Assembly Procedure
1. Remove the ice machine front-cover panel, top-cover panel and side-cover panels from the
ice machine frame.
2. Remove all shipping materials from the ice machine. Cut off the water plate shipping strap.
3. For proper operation the ice machine and ice bin must be on a level surface. If the surface the
ice bin will be installed on is not level use shims or the adjusters on the ice bin legs to bring the machine to level. If shims were used, seal the bin to the floor using a sealant with NSF certification. If there are gaps larger than 1/8” (3mm) install a cove molding around the bottom of the bin to reduce the gap and seal the cove molding to the floor with the approved sealant.
4. Confirm that the following holes are installed in the bin top: a hole corresponding to the ice
drop zone, drain pan outlet, bin level probe and the threaded mounting holes for the supplied bolts at the four corners of the machine. The hole for the drain pan outlet should be 2”(5cm) in diameter to allow sufficient access for the clamp. Drain hoses for drain pan outlets in GT36x, GT56xA, GB56x and the lower halves of GB106x models get directed through the back of the ice bin. Drain hoses for drain pan outlets in GT56xL and the upper halves of GB106x models get directed through pre-cut holes in the back of the ice machine frames. Drain pans should never be allowed to drain directly into the ice bin. After installation, seal around the drain tube where it leaves the machine.
Note: All KOLD-DRAFT bins will have a provision for the drain pan outlet tube to exit the rear of the bin. Ice machines that will be used on bins not manufactured by KOLD-DRAFT will require a drain riser adapter made by KOLD-DRAFT to allow sufficient clearance for the drain pan outlet tube to exit the back of the assembly.
5. Install gasketing on top of bin if not already installed. Gasket material must be positioned so
that it extends to the outside edge of the perimeter of the ice maker chassis when the ice­maker is in place. To apply the gasket, peel away the white backing strip and press firmly in place.
6. Carefully lift the ice machine and position it on the ice storage bin. Securely attach the ice
machine to the ice storage bin with the supplied washers and bolts or other non-corroding hardware if not installed on a KOLD-DRAFT bin. If the ice machine is installed on an installed with an accessory such as a crusher, follow the installation instructions with the other equipment.

7. Make all plumbing and electrical connections to the ice machine and ice storage bin in
accordance with local regulations.
8. Remove the strap securing the bin level probe and install through the bottom of the ice
machine. Ice machines on top of other ice machines or ice crushers should have the bin probe stuck through the bottom of the machine directly above the bin. The hole for the bin probe will be in the same location on all variations of these machines, just to the right of the ice-making compartment or the ice chute in GT56x applications.
9. Install the ice deflectors. Front Deflectors:

INITIAL START PROCEDURE
1. Be sure that the on-off switch is in the “off” position and the ice-clean switch is in the “clean” position.
2. Turn on the power and water supply and check all supply lines for leaks.
3. Make sure all pump and water tank hoses are connected, then pour 1/2 quart (1/2 liter) of clean potable water into the circulation system to lubricate and prime the pump(s).
Note: this can be done by either pouring the water directly onto the evaporator, the evaporator is equipped with drain holes for this purpose and to allow melted frost to drain into the water tank. In tight spaces a funnel and hose can be used to pour water onto the evaporator. Alternatively the water can slowly be poured into the clear control stream box on the front of the water plate or between the evaporator and the top left wall of the water plate.
4. Move the on-off switch to the “on” position and observe the water flowing from the distributor tube filling the water tank. Also, observe that the water pump is circulating water through the system. A momentary sucking cavitation sound is normal at the beginning of the process when the water level is low. The water fill is complete when the water level in the probe tube reaches the high-level probe. Observe that the water valve is de-energized by ensuring water has stopped flowing through the distributor tube. Check that there are no water leaks from the hoses or water tank into the drain pan.
Note: For GB106x models, observe that the water fill difference between the upper and lower water tanks measured from the top of the control stream box is less than ⅛ inch (3 mm) for “C” models and ¼ inch (6 mm) for “HK” models.
5. Pull down on the right side of the water plate, stretching the springs until the water plate switch is disengaged, observe that the pump stops and the actuator motor rotates the cam arms counter-clockwise. Observe that the cam arms continue to turn, opening the water plate fully, dumping the water in the tank. After a moment, the cam arm rotation will reverse and close the water plate. The cam arm rotation will stop when the water plate is fully closed and the water fill process will repeat.
6. Move the ice-clean switch to the “ice” position, the water plate will cycle down and up one more time dumping the water. When this completes the machine will begin to make ice, observe that the compressor and the condenser fan motor, if so equipped, begin to run. If possible with liquid cooled models ensure there is water flow during the ice making cycle.
7. Test the bin level control operation by holding ice against it. Adjust the controller, if required, to shut off the ice machine within 30 seconds of contact between the ice and probe.
8. Make sure that the drain pan, ice deflectors and stacking chute (GB106x models and stacked ice machines only) are properly installed. Replace and secure all the cabinet panels. The front panel gets secured to the machine with the provided stainless steel sheet metal screws.
9. Discard all the ice from the start-up cycles, then clean and sanitize the ice storage bin according to the instructions provided with the bin.
10. Complete and mail the registration certificate to the factory. Leave all instructions with the owner/user.

ICE MACHINE CLEANING PROCEDURE
It is recommended to perform this cleaning procedure at a minimum twice per year.
Note: Use a clean plastic bottle fitted with a stopper or cap that has a pouring tube and a vent to facilitate mixing and pouring of the specified solutions.
1. Mix 3 oz. (500023 ) KD Nickel-Safe Ice Machine Cleaner per gallon of warm water.
2. If the ice machine is operating, wait until the ice falls out of the evaporator, then move the
Ice-Clean Switch to the “Clean” position.
3. Empty the storage bin and turn off any other ice machines on the same bin.
4. After the water fill is complete, turn off the ice machine. While pinching the water level
control tube, remove it from the probe cap. Hold the water level control tube high enough so that the water does not overflow, release the control tube and pour about half the cleaning solution into the top of the probe tube. Pinch the control tube again and reassemble the probe tube to the cap. Pour the remaining cleaning solution into the control stream box.
5. Turn on the ice machine and allow the solution to circulate for 15 minutes then pull down
on the right side of the water plate. This will cause it to open and dump the cleaning solution and then refill with water. Repeat the dump process three times to be sure all the cleaning solution is rinsed out of the machine.
6. Mix a sanitizing solution containing 0.5 ounce (15 mL) 5-1/4% sodium hypochlorite
(household bleach or equivalent) and 1 quart (3.8 Liter) clean water.
7. Using the same process as in step #4, pour half of the sanitizing solution into water level
probe tube and the other half into the control stream box.
8. Allow the solution to circulate for 15 minutes. Pull down on the right side of the water plate,
to cause it to open and dump the sanitizing solution and then refill with water. Repeat this process two times to be sure all the cleaning solution is rinsed out of the machine. If necessary, adjust the water level probes to the proper levels.
9. While the cleaning and sanitizing solutions are circulating, clean and rinse all accessible
parts and surfaces of the ice machine with clean towels and . Mix a cleaning solution containing 8 tablespoons (1/2 cup) (96g) baking soda and 1 Gal. (3.8 Liter) of warm water and a sanitizing solution containing 1 teaspoon (5 mL) 5-1/4% sodium hypochlorite and two quarts (1.9 Liter) of clean water.
10. After cleaning has been completed, move the Ice-Clean Switch to the “Ice” position. Check
the operation of the machine, particularly the water level and subsequent ice cube formation. Adjust the water level probes if needed.

COMPONENTS
Mechanical Components Refrigerant Compressor: Provided to pump refrigerant through the refrigeration system. See
the serial number plate for refrigerant specification and electrical characteristics. Condenser: All air-cooled and liquid-cooled models are provided with a self-contained refrigerant
condenser to remove heat from the refrigeration system. These condensers are designated in the model number as (“A”) air-cooled and (“L”) liquid-cooled. Remote air-cooled condensers are also available for some models. These are designated as (“R”) in the model number. (See the remote air-cooled section of the manual for information on these models.)
Condenser Fan and Motor: Provided with all air-cooled (“A”) models to draw air through the condenser.
Liquid Regulator Valve: Provided with all liquid-cooled (“L”) models to regulate the flow of coolant through the condenser and maintain a specified refrigerant discharge pressure.
Heat Exchanger: Provided to sub-cool the refrigerant, ensuring that the refrigerant is liquid at the inlet of the expansion valve.
Filter Drier: Provided as insurance that all moisture and impurities are removed from the refrigeration system.
Thermostatic Expansion Valve: Maintains the proper flow of refrigerant, through the system, as the load changes during the ice making cycle.
Evaporator: A plated copper evaporator is found in all models. The evaporator provides the five freezing surfaces for ice cube formation.
Defrost Valve: Directs compressor discharge gas to the evaporator, warming it to release the ice cubes during the harvest cycle.
Water Tank: Provided as a sump to hold the water required to make one batch of ice cubes. Water Solenoid Valve: Opens to allow potable water to enter the ice machine and closes when
the water tank is filled to the correct level.
Note: There is a strainer in the water valve inlet, which protects the water valve from particles in the water supply. If the need for cleaning this strainer is frequent, an external water filter should be provided.
Water Plate: Functions as a water manifold with a flat surface and to regulate the web thickness between the cubes. This surface is positioned close to the evaporator and acts to form the sixth side of the ice cubes. The water plate surface has one spray hole for each cell in the evaporator, to provide water to the freezing surfaces. The water plate surface also has two drain holes under each cell, to allow unfrozen water to return to the water tank to be re-circulated. The water plate swings down during the harvest cycle to allow the ice cubes to fall out of the evaporator.
Note: If at any time during the Fill, Freeze, or Circulate cycle the water plate is manually opened the controller will switch to the step 3 of the ice making sequence on page 26.

Caution:
Water Pump: Continuously circulates the water from the water tank, through the water plate
during the ice making cycle. The water pump also operates during the wash cycle to circulate cleaning and sanitizing solution.
Actuator Motor: Rotates the cam arms counter-clockwise, at the beginning of the ice harvest cycle, to lower the water plate, so the ice can fall out of the evaporator. It then rotates clockwise, at the end of the harvest cycle, to close the water plate for the next ice making cycle.
Actuator Motor Capacitor: Installed between the two actuator motor windings, the function of this capacitor is to determine the direction of the rotation of the actuator motor.
Cam Arms: These are attached to the actuator motor output shaft and function initially to separate the water plate from the evaporator and then to support the water plate as it opens fully.
Water Plate Springs: Function as the connection between the cam arms and the water plate. They also act as a safety mechanism, stretching if any ice remains on the water plate surface as it is closing against the evaporator.
Drain Pan: Provided to catch the dreg water at the end of the ice making / cleaning and sanitizing cycles and directs it to the drain.
Ice Deflectors-Front and Rear: Provided to direct the falling ice to the storage bin. Controller: Controls the ice machine utilizing multiple sensors. Provides power directly to many
of the ice machine components, through solid-state relay outputs and indirectly to the compressor and condenser fan motor, if so equipped, by operation of a contactor. The controller also provides status indication of the ice machine and components as well as diagnostics for service personnel.
On-Off Switch: The “On” position provides power to the controller to operate the ice machine. The “Off” position interrupts power to the controller to shut down the ice machine.
Switching the machine “off” does not de-energize circuits, disconnect power before servicing.
Ice-Clean Switch: The “Ice” position signals the controller to provide full operation of the ice machine. The “Clean” position signals the controller to exclude operation of the contactor and thereby the compressor and condenser fan motor if so equipped This position is useful for cleaning the ice machine and for test procedures where operation of the compressor is not required or desired.
Ice Level Probe: Senses when the ice bin is full- Contact between this probe and the ice in the storage bin will signal the controller to shut off the ice machine. When ice is removed from the probe, the ice machine will restart.
Adjustment: While holding ice against the probe tube, turn the adjustment knob on the controller to shut off the ice machine within one minute. A warmer (CCW Bottom blue knob) adjustment will shut off the ice machine sooner. A colder (CW) adjustment will delay shut off.
16
Evaporator Temperature Probe: Senses the temperature of the evaporator. During the defrost cycle, the evaporator must warm sufficiently to release the ice. This probe signals the controller to terminate the defrost cycle, after the ice has fallen out of the evaporator, and start the next ice making cycle.
Note: A secondary function of this probe is to signal the controller to shut off the ice machine if the evaporator should overheat.
Adjustment: Turn the adjustment knob on the controller warmer (CCW Top blue Knob), only if the defrost time is insufficient to drop all the ice from the evaporator, before the water plate begins to close. The defrost time should be increased no more than is required to ensure all the ice has fallen from the evaporator.
Control Stream: This is a small clear box, divided into two sections and located on the front face of the water plate. It is a “safety valve” that ensures evacuation of the water reservoir so that harvest cycles will begin without undue delay. Water flowing into the left section of the box is returned to the water tank and re-circulated through the system. Water flowing into the right section of the box is drained out of the system. The velocity of the stream flowing in the box, during the ice making cycle, is an indicator of the water pressure inside the water plate. This pressure will increase as the ice cubes fill out in the evaporator, covering the drain holes provided for each cell. This pressure increase will cause the stream, normally flowing into the left section of the box, to flow over the partition and into the right section, draining the system of excess water.
Adjustment: Turn the Philips head screw located behind the expansion valve such that the stream of water falls to the left of the control stream box partition, during the early portion of the ice making cycle, before the cubes are full.
Water Level Probe Assembly: This assembly consists of three stainless steel probes which are positioned in a clear water level tube. The water level tube is mounted in front of the water tank and is connected to it by a hose. The water level in the tank is visible in the tube. The water level probes are positioned in the water level tube. The longest is a reference probe and the tip of this probe is at the bottom of the tube. The next longest probe is the “LOW PROBE.” When the water level is low enough to separate from the tip of this probe, the controller is signaled to start the harvest cycle. The shortest probe is the “HIGH PROBE.” When the water level touches the tip of this probe during the water fill, the controller will de-energize the water inlet valve.
Adjustment: The reference probe should be adjusted all the way down. The “Low Probe” should be adjusted so the tip is approximately .60” (15 mm) from the bottom of the probe tube. The “High Probe” determines how much water is taken into the system at the beginning of a cycle. It is adjusted as required by the size of the cube (“C” or “HK”) and the desired fullness (dimple size) of each cube. Typically all cubes should have a small dimple at the end of the freeze cycle. Lack of a dimple in the cubes is an indicator that the water tank level is too high at the start of the cycle.
Note: Making cubes without a dimple will reduce ice machine capacity and may damage the water plate surface in extreme cases. If the control stream is draining water for more than 15 seconds, at the end of the ice making cycle, the water level in the tank is too high. Lower the high probe or raise the low probe slightly, until proper operation is evident.

Plate Up Switch: This switch is actuated by the water plate and informs the controller about the position of the plate—fully up or not fully up. If this switch is not actuated when the water plate closes, because ice is remaining on the water plate surface, the actuator motor will reverse and reopen the water plate. This will continue until the surface is clear.
Adjustment: The switch should be actuated when the front cam arm is between the 10 o’clock and 11 o’clock positions. The switch is closed when the “plate up” LED is lit. Adjust the actuation point by adjusting the height of the white actuation screw on the water plate.
Note: Do not bend the switch lever to make this adjustment. Arms Up Switch: This switch acts to limit the clockwise rotation of the actuator motor. It informs
the controller when the cam arms are in the “12 o’clock” position (water plate up), so the actuator motor can be de-energized.
Adjustment: The switch operator, which is attached to the output shaft of the actuator motor, can be rotated on the shaft and fixed in place with a set screw. When adjusted properly, the cam arm will stop in the “12 o’clock” position. The motor stops when the flat spot on the switch operator allows the switch lever to drop down.
Note: The front water plate spring must be on the left side of the cam hub when the water plate is fully closed (cam arm in the 12 o’clock position).
Arms Down Switch: This switch acts to limit the counter-clockwise rotation of the actuator motor. It informs the controller when the cam arms are in the “7 o’clock” position (water plate down), so the actuator motor can be de-energized.
Adjustment: The switch operator, which is attached to the output shaft of the actuator motor, can be rotated on the shaft and fixed in place with a set screw. When adjusted properly, the cam arm will stop in the “7 o’clock” position. The motor stops when the flat spot on the switch operator allows the switch lever to drop down. Do not allow under-travel or over-travel so that the water plate is not in the most fully-open position (critical with HK models)
Contactor: Provided with all models to carry the compressor load. On self-contained and remote air-cooled models, the condenser fan motor is also connected to the contactor. The contactor coil is rated for line voltage and the contacts are rated for definite purpose applications (FLA and LRA).
High Pressure Cutoff: A manual reset pressure switch is provided, which will open the circuit to the contactor coil if the discharge pressure should reach 435 psig (2.38 MPa gauge).
GB106x Series Unique Components Stacking Chute: Provided to direct the ice, from the upper ice making section, down through the
lower ice making section of these machines. Ice Deflectors-Upper Front and Rear: Provided to direct the falling ice, from the upper ice
making section, to the stacking chute.

Stacked Jumpers:
Under normal operation all machines will have a jumper across the left pins. If this jumper is
removed the water valve will stay energized to thoroughly rinse the water plate during the water plate lowering, harvest and water plate rising cycles. Note: The machine will need reset for the controller to acknowledge this change.
The right jumper is used to tell the controller when it is being used on a dual evaporator
machine (GB1064 models only). This is set at the factory and should never be removed.
Programming Port: Used by service technicians to alter or update the controllers software. Water Level Sensor: Port for water level sensor probes. Evaporator Temperature Adjustment: To increase the temperature of the evaporator at which
the water plate closes, turn this dial counterclockwise. To decrease, turn the dial clockwise. The operator can adjust the harvest termination temperature between 35 and 60F.
Note: After adjustment the controller must be reset.
Reset Button: Reboots the controller. Temperature Sensor Port: For evaporator and bin temperature sensor probes.

Description of Each Process
The following sequence begins with the cuber as shipped from the factory with the water plate(s) closed and ready to begin a normal ice making cycle.
Fill: The water solenoid valve will be energized only until the water level reaches the high water level probe, and the water pump will run when the water plate is closed.
REV 1.70

WATER PUMP( WATER VALVE OFF ) AND THEN REFILL TO HIGH PROBE.

Freeze: Once the water fill cycle has been completed, the water solenoid valve will remain de-
energized until the following harvest cycle. The water level in the liquid level probe tube lowers as the water is frozen, but no additional water will be introduced during the freeze cycle. The control stream runs continuously during the freeze cycle with the water returning to the water tank through the hole which can be seen through the control stream box to the left of the dam in the box. The control stream is a "safety valve" to insure the ability to initiate harvest rather than an ice quality control, and it should never need to go over the dam for more than 15 seconds before harvest begins.
Note: No water, other than condensation, should drip or run to the drain pan from the
60 Series Service Manual.rev.1.2012

control stream or from the water tank during the freeze cycle. The water level in the liquid level probe tube must get below the level of the low water level probe initiate the harvest cycle. If there is an excess of water in the water tank, the water pump outlet pressure increases when the evaporator cells are full, and the control stream rises and flows over the dam to the drain pan to evacuate the liquid level control tube.
Lower: When the water level in the liquid level probe tube is below the low water level probe the controller senses the absence of continuity between the probes. Power is applied to the defrost valve coil allowing hot gas to circulate through the evaporator. The evaporator begins to defrost, and the water plate begins to open immediately. When the cam arms down switch is activated the water plate will stop.
Harvest: As long as the evaporator remains cold, the water plate(s) remain in the open position with the water solenoid valve de-energized. The defrost valve remains energized, and the evaporator(s) become warm enough to release the ice which drops by gravity into the ice storage area.
Raise: After the ice is out and the evaporator(s) warm to the reset temperature required by the controller the actuator motor(s) will be energized to close the water plate(s) The water solenoid valve will be energized to begin the water fill for the next ice-making cycle, the defrost valve will be de-energized, and the evaporator will begin to cool.
Ice Bin Full: When the level of ice reaches the bin probe, the ice maker stops automatically, and it remains off until the bin probe warms up when the ice level is lowered.
Note: in remote condenser models (r), the compressor continues to run after bin control shutdown until the low-side is pumped down to the setting of the pumpdown controller. This pressure should be between 5 and 10 psig and must never be vacuum.
Cleaning Mode: All of the cuber's operational components except refrigeration are able to function with the make ice/clean switch in the clean position. Simply placing this switch in the cleaning position does not complete the cleaning and sanitizing of the cuber. Instructions pertaining to the cleaning of a machine can be found on page 11 of this manual.
Note: The frequency of the need for cleaning is determined by the supply water characteristics. The cuber should be cleaned no less frequently than once each 6 months, and it may require more frequent cleaning. The requirement for sanitizing frequency may be contained in local health code regulations.
Water Plate Closure Problems: If the plate up switch is not properly actuated, due to mis­adjustment, weak springs, or an obstruction to the water plate travel, such as ice which did not slide off of the plate, the actuator motor will immediately reverse and re-open the water plate.
Shutdown-High Pressure: All models are provided with a high pressure cutoff which interrupts power only to the compressor, and to the condenser fan motor if so equipped, when the high-side pressure rises to the cutoff setting. The high pressure cutoff requires manual resetting to restore power in all models. When this happens in air and remote cooled models be sure there is sufficient airflow, a clean condenser, and a properly functioning fan motor. In liquid cooled models make sure the liquid regulator valve is adjusted properly and that there is sufficient flow of coolant.

START METHODS
Ice Making Mode Start Up
At power up in the ice making mode the electronic control will monitor the following criteria:
If the evaporator temperature is colder than the Harvest Termination temperature at start up the controller will switch to the Lower state.
If there is an obstruction preventing the water plate from closing the Plate Up switch at startup, the controller will switch to the Lower state.
If the water plate is not in the up position at start up and the evaporator temperature is warmer than the Harvest Termination temperature, the controller will switch to the Raise state.
Cleaning Mode Start Up
At power up in the wash mode the electronic control will monitor the following criteria:
If there is an obstruction preventing the water plate from closing the Plate Up switch at startup, the controller will switch to the “Lower” state.
If the water plate is not in the up position at start up, the controller will switch to the “Raise” state.

Never reset a circuit breaker or replace a fuse without checking for a short circuit to ground.
Caution:
COMPRESSOR TEST PROCEDURE
Warning:
Refer all service work to qualified technicians.
Knowledge of proper installation and service procedures is essential to the safe maintenance
of KOLD-DRAFT equipment.
Do not operate equipment that has been damaged.
Always disconnect the power supply before servicing the equipment. Some circuits remain
energized when the ice machine is switched off.
Never operate the ice maker with any covers, panels or other parts removed or not properly
secured.
Never modify the circuitry of KOLD-DRAFT equipment from the original specifications.
Use only genuine KOLD-DRAFT replacement parts.
Use of non-approved parts when servicing KOLD-DRAFT equipment may create a safety
hazard or cause equipment and property damage.
Use of non-approved parts, when servicing KOLD-DRAFT equipment, will void the equipment
warranty.
Disconnect all electrical power before removing the protective terminal cover.
Never energize the system unless the protective terminal cover is securely fastened.
Never energize the system unless the compressor is properly connected to ground.
An open fuse or tripped circuit breaker is an indication of a ground fault. Energizing a compressor with a ground fault may cause terminal pin ejection, which will allow oil and refrigerant to spray out of the system. This oil spray, combined with an electrical spark, can ignite causing harm to personnel and property.
Discharge all capacitors with a 20,000 ohm resister before working with them or removing
them from the ice machine. This must be done to avoid damage to measuring devices and the risk of electrical shock.
Failure to comply with all KOLD-DRAFT service guidelines may cause personal injury, equipment or property damage and voiding of the product warranty.
Note:
When servicing KOLD-DRAFT ice machine refrigeration systems, all work performed must
be consistent with the best refrigeration service practices. These systems must remain clean, dry and properly charged with refrigerant, in order for the ice machine to operate as designed.
See the Remote Air-Cooled Condenser section of the manual for additional service
information related to these ice machines.
All KOLD-DRAFT ice machine models utilize CSR (capacitor start/capacitor run)
compressors. Each model includes a potential start relay, a start capacitor and a run capacitor, in the compressor circuitry, to start and operate these compressors properly and with maximum efficiency. All compressors also include thermal protectors—external on GT36x, GT56x, and GB56x models and internal on GB106x models. This procedure will help diagnose problems with these compressors and all related components.
60 Series Service Manual.rev.1.2012

Test Procedure for a Short Circuit to Ground (Ground Fault)
1. Disconnect all electrical power to the system, making sure all power legs are open.
2. Remove the protective terminal cover. Inspect for evidence of overheating at any connection. Overheating is an indication that a compressor motor problem exists. Disconnect all leads from the terminal pins.
3. Check the compressor for a ground fault using an ohm meter or a high potential ground tester. Connect one lead to the copper suction line and connect the other lead to one of the terminal pins. Repeat this procedure for the two remaining terminal pins. If the instrument indicates any resistance less than 2 mega ohms between any pin and the suction line (compressor housing), a ground fault exists.
4. If a ground fault exists, replace the compressor. Do not reconnect the compressor or re-use any leads or terminal connectors that exhibit signs of overheating.
Test Procedure for Continuity and Proper Resistance
1. If no ground fault has been found, determine if there is an open or short circuited motor winding or if the thermal protector is open.
2. Allow time for the thermal protector to reset. This may take as long as an hour for internal type thermal protectors.
3. For single phase compressors, test the continuity of the start winding by measuring between terminal pins C and S. Test the continuity of the main winding by measuring between terminal pins C and R. If there is no continuity in either winding, replace the compressor.
4. For three phase compressors, test the continuity of the windings by measuring between each pair of terminal pins: 1-2, 2-3 and 1-3. If there is no continuity between any set of terminal pins, replace the compressor.
5. If continuity is found in all motor windings, measure the resistance (ohms) of the windings.
6. For single phase compressors, measure between each pair of terminal pins: C-S, C-R and S-R. The sum of the resistance measured between C-S and C-R should equal the resistance measured between S-R, plus or minus a small deviation. Proper resistance may be confirmed by comparing the measured resistance to the resistance specifications for specific compressor models. If the resistance is not correct, replace the compressor. If the specifications are not found on the ice machine, please contact the factory.
7. For three phase compressors, measure between each pair of terminal pins: 1-2, 2-3 and 1-3. The resistance measured between each pair of pins should always be greater than zero and within 10% of one another. Proper resistance may be confirmed by comparing the measured resistance to the resistance specifications for specific compressor models. If the resistance is not correct, replace the compressor. If the specifications are not found on the ice machine, please contact the factory.
34
Test Procedure for Compressor Electrical Components
1. Testing The Potential Relay:
2. Before testing the relay, be sure it is the one specified for use with the ice machine compressor and the mounting position of the relay is correct.
3. Measure for continuity between terminals 5 and 2—if there is no continuity, replace the relay.
4. Measure for continuity between terminals 2 and 1—if there is no continuity, the contacts are open and the relay must be replaced.
5. The relay may also malfunction if the supply voltage is 10% higher or lower than the rated voltage or if the relay is loosely mounted, allowing it to vibrate or if it is used in conjunction with an incorrect start capacitor.
Testing the Run Capacitor:
1. Before testing the run capacitor, be sure it is the one specified for use with the ice machine compressor.
2. After making sure the capacitor is discharged, disconnect it and test the value with a capacitance meter. If the measured value is more than 10% higher or lower than the rated value, replace the run capacitor.
3. The capacitor may also malfunction if the supply voltage is more than 10% higher than the rated voltage.
Testing the Start Capacitor:
1. Before testing the start capacitor, be sure it is the one specified for use with the ice machine compressor.
2. After making sure the capacitor is discharged, disconnect it and test the value with a capacitance meter. If the measured value less than the rated value or more than 20% higher than the rated value, replace the start capacitor.
3. As an alternative, test the run capacitor by determining if there is continuity across the terminals. Use a meter set to the R x 1 scale. If there is continuity the capacitor is shorted and must be replaced.
4. Another alternative is to set the meter to the R x 100,000 scale. If there is no needle deflection on an analog meter when placing the probes across the capacitor terminals or if infinite resistance is indicated on a digital meter, the capacitor is open and needs to be replaced.
5. The capacitor may also malfunction if the relay contacts are not working properly, or if the capacitor is subjected to prolonged operation of the start cycle, because the start relay is incorrect, the starting load is too high, or the supply voltage is more than 10% lower than the rated voltage.
60 Series Service Manual.rev.1.2012

Additional Service Information
Testing the External Thermal Protector:
After allowing sufficient time for the thermal protector to reset, disconnect it and test for
continuity across the terminals. If there is no continuity, replace the thermal protector.
Disconnect and test the compressor wiring by confirming that there is continuity between relay
terminal 5 and compressor terminal C and also between terminals 2 and S as well as 4 and R.
Replace the potential relay if all other tests do not reveal the problem. A new relay will
eliminate any electrical problems that cannot be determined with the previous testing. If a new relay does not correct the operation, the compressor may have a mechanical problem.
Note: Excessive short cycling may be caused by a faulty thermal protector, but it also may be caused by other malfunctioning system components such as the bin thermostat, Ice-Off-Wash switch, and contactor or high pressure cut-out.

WATER PLATE ALIGNMENT
If the water plate is not aligned with the evaporator, the cubes may appear cloudy or misshapen.
Dimension “A” is not adjustable. If this dimension is out of tolerance, the evaporator or water plate mounting components may be damaged.
Adjustments to dimension “B” can be made by sliding the front and rear hinges along the left edge of the water plate. Lightly tap the hinges as required to align the water plate with the evaporator. Alignment is correct when the space between the evaporator and the water plate is equal in front and in back.
“A” = 1.5” ± 3/32” (38 mm ± 2.5 mm) “B” = 5/16” ± 1/16”(8 mm ± 1.5 mm)
WEB THICKNESS ADJUSTMENT
The web thickness between cubes (the gap between the bottom of the evaporator and the water plate surface) can be adjusted by inserting or removing shims between the support channels and the evaporator support posts or the cam shaft bearing brackets. Loosen the actuator motor mounting screws before inserting or removing shims between the channels and cam shaft bearing brackets. The web thickness specification for both C and HK models is 1/16” (2mm)
38
WATER PLATE UP/DOWN POSITION AND ADJUSTMENT
When the water plate is up (closed), the spring end of the cam arm must be in the 12 o’clock position, with the spring on the left side of the cam arm hub. The arms up switch lever (front) will be down and the arms down switch lever (back) will be up. When the water plate opens, the cam arm turns counter clockwise until the arms down switch operator allows the arms down switch lever to drop. When the water plate is fully down (open), the cam arm should be in the seven o’clock position; the spring should be aligned with the cam arm. When closing again, the cam arm will turn clockwise, until the arms up switch operator allows the arms up switch lever to drop.
The positions of the cam arms, when the water plate is open and closed, may be adjusted by loosening the set screws and rotating the switch operators as required. Baseline positions of the switch operators for the front and back are 11 and 4 o’clock when the water plate is up. When the water plate is down, positions for the front and back switch operators are 6 o’clock and 11 o’clock Note: The front operator is for adjusting the arms up switch and the back operator is for adjusting the arms down switch.
Up Position
If the cam arm in the up position is too far clockwise from 12 o’clock rotate the front switch
operator clockwise to stop the arm’s rotation earlier
If the cam arm in the up position is too far counterclockwise from 12 o’clock rotate the front
switch operator counterclockwise to stop the arm’s rotation later Down Position
If the cam arm in the down position is too far clockwise from 7 o’clock rotate the back switch

ACTUATOR MOTOR ELECTRICAL TESTS
The following tests are for troubleshooting the actuator motor and related circuits: Use an AC voltmeter set for the proper range. Voltages in the tables are measure across the motor reversing capacitor (between the colored motor lead wires.
If there is no ice in the evaporator(s) and the water plate(s) is (are) not fully closed (with the water plate switch(es) pushed up and the “ARMS UP” LED on), the actuator motor(s) and pump(s) should be running. If not, be sure there is power to the motor(s) and also that the motor(s) is(are) not overheated and off due high temperature. Allow the motor to cool down before starting the test procedure.
Always refer to the proper wiring diagram when troubleshooting.
Motor winding resistances at 75˚ F (24˚ C) out of the circuit are as follows: REX 115 volt motors, white to black or yellow, approximately 95 ohms REX 230 volt motors, white to red or yellow, approximately 400 ohms

PROBE TEST PROCEDURE
Water Level Probes:
Water level probes can be tested at any temperature and are good if they exhibit continuity (0 ohms resistance) along the length, between the probe wire and the connector at the controller.
It is advisable to flex the probe at the two connections, while testing for continuity, to eliminate the possibility of an intermittent failure.
Evaporator Temperature and Ice Level Probes:
The evaporator temperature probe and the ice level probe are designed to have a nominal resistance of 5650 ohms at 32° F (0°C). To test the se probes they must be placed in ice water 32°F (0°C) for a minute and then checked for resist ance while the tube is still in the ice water. A probe is considered good if it exhibits a resistance value between 5400 and 5900 ohms at 32° F (0°C). Probes with values outside this range should be replaced.

FOR GB1064 MACHINES BUILT BEFORE 607945
WATER FILL ADJUSTMENT INSTRUCTIONS
Note: This applies only for GB1064 machines with serial numbers before 607945. Machines built after 607945 have an upgraded water valve which equalizes the amount of water in each tank per load.
Since supply pressures vary between the factory and install locations, water fill levels between the top and bottom water tanks will also vary. The water fill difference between the upper and lower water tanks should be less than 1/8 in (3 mm). A dynamic water pressure of 30 psig (0.2 MPa) minimum is required to ensure consistent water fill performance. Before adjusting the water fill levels be sure that the Water Level Probes are properly adjusted and no hoses are kinked. Refer to the Service Manual for the adjustment specifications according to cube size.
To Adjust For Equal Fill:
1. Place the selector in the “CLEAN” mode, switch the Power Switch to “ON”.
2. Pull down on the right side of either water plate, stretching the springs until the actuator motors rotate the cam arms counter-clockwise. Observe that the cam arms continue to turn, opening the water plates fully, dumping the water in the tanks. It may be necessary to turn the power off with the water plates fully open in order to completely drain the water tanks. At this point, the cam arm rotation will reverse and close the water plates. The cam arm rotation will stop when the water plates are fully closed and the water fill will occur. When the fill water reaches the “high-level probe” the water fill valve is de-energized and the water fill stops. A small amount of water will drain back from the water fill tubing to the lower water tank.
3. Compare the water levels in the probe tube and the upper section control stream overflow as seen on the next page to determine if the upper and lower water tanks are filling within the specified maximum difference
4. If the top tank level is lower than the bottom tank level by more than ⅛ inch (3 mm) for “C” models and ¼ inch (6 mm) for “HK” models, squeeze the restrictor clamp to reduce the bottom tank fill rate. If the top tank level is more than ⅛ inch (3 mm) for “C” models and ¼ inch (6 mm) for “HK” models 1/8” higher than the lower tank level, open the restrictor clamp to increase the lower tank fill rate. Small adjustments are recommended. When the adjustment appears to be correct, dump the water by pulling down on a water plate, as above, allow the water tanks to fill again and re-check the levels.

Notes:
The crusher is designed to operate in conjunction with one or two KOLD-DRAFT® ice
makers. Two motor control relay blocks are provided and a relay coil must be installed for each ice maker used. Each relay coil must have a voltage rating matching the voltage of the ice maker, regardless of the crusher motor voltage. T271 crushers are supplied with 115V relays. T274 crushers are supplied with 208-230V relays. The relay coils are installed through the opening in the control box. A third relay is provided for controlling one or two ice makers with the same set of bin thermostats. This relay coil voltage rating is matched to the crusher motor voltage and is provided with the crusher.
A dual safety switch system is employed in the crusher design to break the circuit to the
motor. If either the front panel of the crusher or the front panel of the bottom ice maker is removed, a switch will open the motor circuit. The crusher safety switch is mounted in the crusher control box.
12. Install a grommet in the pre-cut hole in the floor of the ice maker’s compressor compartment directly behind the controller box.
13. Push the safety switch wire assembly (wires with insulated 90 ° flag terminals) and the motor control wire assembly (wires with piggyback terminals) through the grommet into the ice maker
14. Connect the safety switch wires from the crusher to the "Common" and "Normally Open" terminals of the ice maker safety switch (the two outer terminals). (See Wiring Diagram) Note: There are two motor control wire assemblies of different lengths. When using a stacked machine the shorter wire assembly gets connected to the lower ice maker and the longer wire gets connected to the upper ice maker. If the ice maker is not a stacked unit the longer wire is unused
Warning:
The safety switches do not de-energize all circuits in the crusher or circuits in the ice maker. Before cleaning or servicing this equipment disconnect all power supplies.
15. Disconnect the white plug assembly from the ice maker hot gas valve. (If installing a GB1064 ice maker there are two hot gas valves. Use the lower of the two to connect the crusher).

Note:
If two separate ice making machines (for example two GB1064 models stacked) are
installed the bin thermostats of both ice makers will need to be connected to the crusher.
Ensure that the thermostat cable is not routed through the ice chute. Do not run the cable
through the same hole that the safety switch wire assembly and the motor control wire assembly are run through.
Initial Start-Up
1. Ensure all electrical connections were made properly and turn on the electrical service.
Note: There is no on-switch, the machine will run when the ice-maker tells it to.
2. Adjust the bin thermostat to turn off the ice maker before the ice level is above the guard
screen.
3. Adjust the thermostats to shut off the ice maker approximately 1 minute after the ice contacts
the capillary tubes.
Note:
If ice is allowed to collect above the screen it will not clear when the ice below is removed.
This condition will cause ice to pile up in the chute of the crusher and ultimately, damage the ice maker
The use of the bottom guard will reduce the effective volume of the bin
ICE CRUSHER OPERATION
With the crusher knob in the crushed position, ice falling from the ice maker will be directed by the selector plate through the crusher mechanism and deposited into the left side of the bin.
The crusher motor is powered through a relay which is energized by the hot gas valve circuit of the ice maker. The selector knob must be in the crushed position to close a switch and complete the circuit to the motor. Additionally, the front panel safety switches must be depressed (covers on) for motor operation.
With the crusher knob in the "CUBE" position, ice falling from the ice maker will bypass the crusher mechanism and be dumped into the right side of the bin. The crusher motor will not be energized.

ICE CRUSHER CLEANING PROCEDURE
Disconnect or turn off all ice machine and crusher fuses or breakers before cleaning either
machine.
Do not use ammonia solutions or strong detergents in cleaning the crusher.
Never use appliance polishes, finish preservatives or cleaners in areas that could contact ice.
Warning:
Always clean the ice maker first, following the ice maker cleaning instructions.
Remove all ice from the bin before starting the cleaning procedure.
Clean and sanitize storage bin last.
1. Remove ice maker panels, ice chute, deflectors, drain pan, crusher front panel and belt guard.
2. Wash interior with a solution of 2 tablespoons of baking soda per quart of clean warm water, 140°F (60°C) max. The crusher ice hopper can be acc essed from the front and left side of the ice maker. Use a long handled brush to clean inside the hopper, as crusher teeth are sharp and can cause injury.
3. The bottom area of the crusher ice hopper can be accessed from inside the ice bin. Use a long handled brush.
4. Wipe down internal cabinet walls with a cloth soaked in cleaning solution.
5. Rinse with clean tap water.
6. Sanitize all ice contact surfaces with a solution of 1/2 teaspoon 5-1/4% sodium hypochlorite (chlorine bleach) per quart of clean tap water (minimum 100 PPM free chlorine). A spray bottle will facilitate this process.
7. Pour the remaining solution into the crusher chute, slowly, while rotating the cutter wheel by hand turning the pulley.
8. After adjusting and lubricating crusher (See following section), replace all enclosure panels and connect the electrical supply.
9. Exterior surfaces may be cleaned by standard methods suitable to the stainless steel finish.
ADJUSTMENT AND LUBRICATION
1. Oil the crusher motor (if ports are provided) and grease the shaft bearings. (Do not over-lubricate)
2. Check the belt and pulleys for excessive wear. Adjust the belt tension to deflect 5/32 inch with two pounds applied to the center of the span.
3. Tighten any loose set screws, machine screws, nuts and electrical connections.

Remote condenser ambient air temperature: 110°F (43°C) maximum
Try to keep the compressor warmer than the condenser. In most installations, the ice maker
runs enough so that residual motor heat minimizes liquid migration to the crankcase. If the ice maker is in a cool location, or if it will be OFF for extended periods, a crankcase heater should be installed.
Avoid placing the condenser in the exhaust air stream of other equipment or within a distance

equal to the width of the condenser from a wall or another piece of equipment. Stay away from kitchen exhaust fans to prevent grease accumulation on the fins. Use a curb, which extends above the deepest expected pond in the condenser area of the roof.
Installation
1. Unpack the condenser and install the mounting legs.
2. Fasten the condenser to its mounting surface using methods that will satisfy the building codes in your area. The condenser must not be lower than the receiver.
3. The line sets are packed separately, with the quantity and length marked on the carton. Make sure that the lines are correct for your installation.
4. A single circuit condenser installation, which uses one line set, will require a 1-3/4" dia. hole to pass the lines through a ceiling or wall. The lines for a 2 circuit condenser require a 2" dia. hole.
5. Each line set consists of a 3/8" liquid line, and a 1/2" insulated discharge line. Connect the 3/8" line to the lower (liquid) fitting on the condenser, and to the "Refrigerant In" on the ice maker. The 1/2" line connects to the upper (inlet) fitting on the condenser, and the "Refrigerant Out" on the ice maker.
6. Each fitting on the line sets, condenser and ice maker is self-sealing, and should be tightened 1/4 turn more than hand tight. Always use a backup wrench to prevent tubing twist when tightening these fittings.
7. The condenser fan motor requires power supply provisions that comply with all applicable code requirements. The Ice Maker is provided with wire connection pigtails that include an L1 red wire for connection to the fan motor circuit along with L2 and Grounding conductors.
8. The refrigerant lines should be routed inside the building or otherwise mechanically protected wherever possible.
For multiple-circuit installations fan power must be provided separately by a circuit that will not be interrupted so that the fan motor will run continuously.
Remote condenser Ice Maker models from the factory are provided with adequate refrigerant charge to accommodate all acceptable condenser ambient temperatures and up to 50 ft. refrigerant lines. The Ice Maker Nameplate label on the rear of the cabinet indicates the factory charge amount, maximum total charge, and refrigerant type. Ice makers are provided with re­sealable refrigerant line connection couplings.

Minimum Total Charge Required
Note:
The factory charge in dual-evaporator models is 168 oz (10.5 lb) R-404a.
The maximum total system charge for dual-evaporators is 208 oz (13 lb) R-404a.
The basic charge for a dual-evaporator model is 3 lb R-404a.
To determine the total charge, add the following to the basic charge below:
1. For each 10 feet of 3/8” O.D. liquid return tubing add 6 oz of R-404a.
2. For each 10 feet of ½” O.D. compressor discharge line >70o F add ½ oz R-404a.
3. For each 10 feet of ½” O.D. compressor discharge line <70o F add 11 oz R-404a (assume that at least 15’ will be <70o F if not certain).
4. Use the following amounts of R-404a according to the condenser model and the MINIMUM ambient temperature expected at the condenser:

GB1060R models is 10.5 lb.
Do not exceed the specified maximum total system charge.
Interconnecting lines over 50’ are not recommended.
Lines must be pitched upward toward the condenser with no “droops” or traps.
Note: The compressor will start immediately when power is applied, regardless of the “On/Off” or
the "Make Ice/Clean" switch positions, if the low-side pressure is at or above the pump-down controller cut-in setting and the high-pressure cutout is not open. Be sure that the compressor stops when the low-side pressure is between 5 and 15 psig.
