• Each ice maker and each ice bin must enter the drain stack through separate connections.
Models equipped with a liquid condenser that does not re circulate 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.
• Electrical service must fall within the voltage tolerances listed below:
Nominal (V)
115 (1 Series)
208-230 (4 and 5 Series)
No-Load Maximum Full-Load Minimum
250 198
230 (7 Series)
220/380 (8 Series)
250
420/3 phase
210
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.
DANGER: Failure to comply with these regulations may cause serious injury or death and cause damage to the machine and its surroundings.
Warning:
Water Treatment: There are no specific requirements for water treatment provided 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.

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 gasket 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 ice-maker 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.
DANGER: It is highly recommended that 2 or more people perform this job, if the machine falls it could cause serious injury or death.
8
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.

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 28.
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 relays, outputs and indirectly to the compressor and condenser fan motor, if so equipped, by operation of the 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.
Caution:
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 or a float type 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 or float 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. The water level probe float type has a HIGH float and LOW float. As of 1/1/17 we will be adding a dual float, left side float is for harvest, right side is for water level. Adjustments stay the same.
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.
The water level probe float type has a HIGH float determines how much water is taken into the system at the beginning of a cycle and LOW float when it is low enough to tip the controller is signaled to start the harvest cycle.
Note: Making cubes without a 1/8 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.
WATER LEVEL ASSEMBLY (FLOAT TYPE) INSTALLATION INSTRUCTIONS
DOCUMENT #307 1054 01
CAUTION! RISK OF PERSONAL INJURY, PROPERTY DAMAGE, EQUIPMENT FAILURE OR FIRE
Refer all maintenance to qualified personnel. Disconnect power before servicing equipment.
Read and understand all instructions before proceeding.
REMOVE OLD WATER LEVEL PROBES, WIRE HARNESSES AND CONNECTORS
Remove the old water level probe assembly, wire harnesses and connectors from the control box all the way to the water level tube on the water plate. Start in the top right corner of the control box. On the PC board, there is a small black connector with black, white and red wires. Un-clip it and remove it thru the hole in the top/back of the control box. Remove all connected wire harnesses & connectors all the way to the water level tube on the water tank. Note which way the wiring is routed, for installation of the new water level probe assembly. You may cut out the wiring & connectors from the old water level probe assembly as needed. All new wire harnesses and connectors will be supplied with the new water level probe assembly.
CONNECT NEW WATER LEVEL PROBE, WIRE HARNESSES AND CONNECTORS
1. In the replacement kit, find the harness with the small black connector on one end. Feed the black connector thru the hole in the control box and plug it into the PC board. The terminals on the other end of the harness will be connected in step 3 below.
2. Place the new probe with the correct float setup (see FLOAT SETUP below) into the water tube and hang it back onto the top edge of the water tank. Run the other end of the probe wire harness thru the machine to near the back of the control box.
3. Connect the terminals on the ends of the black, white & red wires to the terminals on the ends of the black, white & red wires on the harness you installed into the control box in step 1 above, being sure wire colors correspond for each connection.
FLOAT SETUP
In order for the probe switches to correctly work for K CUBE machines the top float must be flipped over so the magnetic strip is on top. The round blue disk above the top float must also be moved down to the empty grove below it. Both the K and C/HK setups are shown in the picture below. The black dots indicate where the magnetic strip is. If you are unsure where the magnetic strip is located, hold the float up to a light source and the magnetic ring will be more easily identified.
FLOAT ADJUSTMENTS
In order for the machines to make a solid cube some adjustments may be needed. If the ice being harvested is too light or does not have the right dimple size to make it solid, the entire probe will need to be raised slightly. This can be done by grabbing the probe at the top and pulling slightly. If the ice is too solid and there is no dimple in the ice cube then the probe needs to be lowered.
Grabbing the probe at the top and pushing it in will lower it. Raise or lower the probe for right ICE CUBE QUALITY Proper adjustment of the control stream and water level probes will produce ice cubes containing a 1/8" to 3/16" dimple.
18
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/magnetic 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/magnetic should be actuated when the front cam arm is between the 10 o’clock and 11 o’clock positions. The switch/magnetic 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).As of 04/16 new AUTOMATIC no need to reset it.

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, 1.8
ICE MODE and CLEAN MODE: WATER WILL NOW HIT HIGH PROBE, THEN TURN ON
WATER PUMP( WATER VALVE OFF ) AND THEN REFILL TO HIGH PROBE.
CHANGED HIGH AND LOW WATER DEBONUNCE
-0.5 –SECOND DELAY NOW APPLIES WHEN RETURNING TO THE FILL STATE
-ENTIRE FILL ROUTINE WILL NOT BE REPEATED IF RETURNING TO THE FILL STATE
FROM THE HI WATER DEBOUNCE STATE,ONLY REFILLING TO THE HI WATER PROBE
-0.5-SECOND DELAY NOW APPLIES WHEN RETURNING TO THE FREEZE ( ICE MODE )
OR CIRULATE ( CLEAN MODE STATE
Freeze: Once the water fill cycle has been completed, the water solenoid valve will remain deenergized 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 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 arm 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 pump down controller.
This pressure should be between 5 and 10 psig and must never be vacuum.
Cleaning Mode: All of the cuber 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.
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.
Caution:
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.
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.

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.
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.

16. Water plate must be aligned with the evaporator per
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)
40
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 operator clockwise to stop the arm’s rotation later
• If the cam arm in the down position is too far counterclockwise from 7 o’clock rotate the back operator counterclockwise to stop the arm’s rotation earlier
Note: Component relationships and/or operation, other than described, indicate component failure, maladjustment or improper reassembly when servicing the ice machine.
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 these probes they must be placed in ice water
32°F (0°C) for a minute and then checked for resistance 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.

• Always securely attach individual machines together.
• Do not install the equipment in wet areas.
• Do not locate the equipment near any heat source, in direct sunlight, in high ambient areas, or without proper clearance for ventilation. Placing equipment in these locations will result in reduced capacities, high system pressures and may cause equipment failure.
Pre-Install Checklist
• 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 crusher must be connected to the grid through its own dedicated fuse or HACR type circuit breaker.
• Each ice crusher 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.
• Electrical service must fall within the voltage tolerances listed below
Nominal (V) No-Load Maximum Full-Load Minimum
115 (1 Series)
208/230 (4 Series) 250 210
• Breaker or fuse rating 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 8 meters (26 feet) in length. For a conductor length over 8 meters, increase the wire gauge as required by code.
DANGER: Failure to comply with these regulations may cause serious injury or death and cause damage to the machine and its surroundings.
Assembly/Installation
1. Position the ice storage bin maintaining the minimum clearances specified in the ice maker instructions.
2. Level the bin with adjusters on its legs, or by shimming if the bin is to be sealed to the floor. If there are gaps between the bin and the floor greater than 1/8 inch, install a cove molding around the bin bottom. Seal the bin (and molding) to the floor with NSF Certified RTV sealant
(Dow-Corning RTV 732 or equivalent).
3. Install gasket 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 crusher chassis when the ice crusher is in place. To apply the gasket, peel away the white backing strip and press firmly in place.
4. Place the crusher on a flat surface. If the floor is a rough or marring surface place a large rag or rubber mat on the floor to the left of the crusher and stand the crusher on its left side.
5. Position the bottom guard so that the right side flange is hung over the ice breaker bar.
6. Install the left side flange over the mounting studs and secure in place with the supplied 1/4-
20 lock nuts.
Note: Use care when positioning the ice crusher on the bin so that the guard is not damaged.
Be sure to check for internal bin components such as deflectors, dividers etc., which may interfere with the guard during installation.
7. Carefully lift the crusher and place onto the bin. Remove the front cover and note the alignment of the mounting holes in the chassis if mounting means are provided on the bin.
Follow the bin installation instructions for securing the crusher to the bin.
Note: The plastic selector knob must be removed before the front cover can be removed on older machines.
8. Insert the straight thermostat holder tube into the rubber grommet located directly behind the crusher motor. Route the crushed ice thermostat capillary tube through the straight thermostat tube holder. Ensure that the capillary tube is slightly protruding from the bottom of the tube holder.
72
Place the cube ice thermostat capillary tube into the bent thermostat tube holder. Ensure that the capillary tube is slightly protruding from the bottom of the tube holder. Mount the tube holder as shown using the supplied hardware. Tighten the clamp screws. The picture below is a view of the right side of the crusher assembly from within the crusher frame. This portion will be above the un-crushed cube side of the bin.
9. Install gasket on top of crusher.
10. Remove the ice maker cabinet panels, lift and position ice maker on top of crusher with gasket and align the mounting holes. Install cap screws, lock washers and nuts.
11. Mount the ice maker safety switch as shown. If not provided, locate and drill two 3/16 inch dia. holes in the ice maker lower front rail. Mount the safety switch support with the #8-32 screws and lock nuts provided.
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).
16. Connect piggyback terminals of the motor control wire assembly to the tabs of the hot gas valve on the ice maker.
17. Reconnect the white plug assembly to the piggyback terminals of the motor control wire assembly as shown below.
18. Locate the bin thermostat of the ice machine and cut the probe off of the end of the cable
19. Route the cable through one of the small holes in the bottom of the ice machine and into the back of the crusher control box
74
20. Pull the cable out through the front of the crusher control box and cut off the cable to a manageable length.
21. Strip the outer cable jacket back about 3”. Then strip the red and black wires back about ¼”.
22. Connect the stripped wires to the left relay as shown.
Upper Ice Maker Thermostat (If Installed)
Lower Ice Maker Thermostat
23. Turn off the breaker or disconnect the fuse that will service the machine.
24. Make all electrical connections to the electrical service in a manner that complies with local code
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.
76
ICE CRUSHER CLEANING PROCEDURE
DANGER:
• 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 accessed 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.

• KOLD-DRAFT reserves the right to disallow any warranty claims which result from the use of non KOLD-DRAFT condensers and/or line sets.
• Read the entire manual before installing, operating or servicing the machine.
Pre-Install Checklist
• 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.
• 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 8 meters (26 feet) in length. For a conductor length over 8 meters, increase the wire gauge as required by code.
• 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.
80
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.
Caution:
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 >70 o
F add ½ oz R-404a.
3. For each 10 feet of ½” O.D. compressor discharge line <70 o
F add 11 oz R-404a (assume that at least 15’ will be <70 o
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:

EXAMPLE: Calculate the minimum total system charge for a GB1060R Ice Maker with an
RC214APV (single-circuit, 2-ton) condenser and 30 feet of interconnecting tubing with -20
o
F minimum condenser ambient temperature. The calculation would be as follows: 3 lb (basic charge) + 16.5 oz (15’ of ½” O.D. discharge line at <70 o
F) + 0.75 oz (15’ of ½” O.D. discharge line at >70 o
F) + 3.5 lb (flooded condenser at -20
o
F) = 121.25 oz (7.6 lb). The factory charge for
GB1060R models is 10.5 lb.
Caution:
• 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.

Installation Information
WARNING:
• Instruct all personnel in the proper use of the equipment.
• Clean up any liquid spills immediately.
• Always install equipment on a stable and level surface.
• All models are intended for indoor use only. Do not install the equipment in unprotected outdoor areas.
• Do not install the equipment in wet areas.
• Do not locate the equipment near any heat source, in direct sunlight, in high ambient areas, or without proper clearance for ventilation. Placing equipment in these locations will result in reduced capacities, high system pressures and may cause equipment failure.
NOTE: Each Kold-Draft ice machine has successfully completed a quality assurance test and has been factory inspected before shipping.
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.
Remove all packaging materials from the ice machine and protective film from the stainless steel surfaces.
Carton Contents
• Kold-Draft SC200 Series Ice Machine
• Warranty card attached to the front of the machine (must be fully completed and returned
to the factory within 15 days of installation to register this product and to initiate warranty
coverage.) NOTE: Failure to return this registration form will void your warranty.
• Installation & Operation Manual. Leave these with the owner/user.
Installation Requirements
• The ice machine must be installed indoors and the location should be free of airborne contaminates including any corrosive elements.
• Ambient air temperatures at the install location must be between 45°F (7°C) and 90°F
(32°C).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 may cause the machine to be unable to eject the ice from the evaporator. Ambient temperatures less than 60°F (15°C) may cause the bin probe to malfunction.
• The machine may be built into a cabinet. Clearance is not required around the top and sides, but must be provided in back for plumbing and electrical connections and in front for free flow of air in and out of the condensing unit compartment.
• Do not install air cooled units in closets or small rooms where the free flow of air to the unit is restricted.
• The location must not be near heat generating equipment.
• The location must not be near anything that can contaminate it or the ice inside.
• The ice machine should be mounted on the legs provided and leveled by screwing the leg adjusters in or out as required. If the legs are not used, shim the bottom of the machine as required to make it level. Seal any gaps at the floor with approved sealant or use cove molding for larger gaps. Make sure the lower front cover remains removable for service.
• The location must be capable of supporting the weight of the ice machine, with a full bin of ice.
Plumbing
• The drain hose or pipe must not be reduced in size from the machine to the drain. The building drain must be able to accommodate all the drain water from the ice machine operation.
90
• 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
1.5” (38mm) air gap must be provided at each connection. This is to prevent any backflow of drain water into the ice maker or ice bin.
NOTE: Installation must provide adequate backflow prevention to comply with applicable federal, state and local codes.
• Drain lines will be installed with a minimum drop of 1/4” per ft. (2.1cm per meter) run. Ice machine drains and bin drains may be insulated to prevent condensation.
• Water supply temperature must be between 45°F (7°C) and 90°F (32°C). 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.
• The water supply must be potable, not laden with sediment, and have free chlorine levels no greater than 0.2ppm. Supplies with higher chlorine levels should be filtered. There are no specific requirements for water treatment, but the use of water conditioning may increase the intervals between cleaning operations and overall machine life. Please consult a local water conditioning supplier for specific recommendations for your area.
• A minimum 20 psig (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).If a water pressure regulator is used the recommended setting is 30 to 50 psig (0.2 MPA to 0.3 MPA) dynamic.
All water lines must be purged before connection to the ice machine
Electrical
WARNING: Failure to comply with these regulations may cause serious injury or death and cause damage to the machine and its surroundings.
CAUTION: Switching the machine “off” does not de-energize all circuits. Always disconnect power before servicing.
• All KOLD-DRAFT models are intended to be installed with a permanent connection to the field electrical supply. See rating plate on the back of the machine for power supply requirements.
• 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.
• Electrical service must fall within the voltage tolerances listed below:

Initial Start Procedure
11. Be sure that the on-off switch is in the “off” position and the ice-clean switch is in the “ice” position.
12. Make sure all water lines and hoses are securely connected, turn on water supply and check for leaks.
13. Move the on-off switch to the “on” position and observe the water plate opening. Any water in the tank will then be drained. The compressor will turn on, the water plate will close and the sump tank will start to fill.
92
14. 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. Check that there are no water leaks from the hoses or water tank into the bin.
15. The machine will begin to make ice.
16. When ice is available, test the bin probe adjustment by holding ice against it. Adjust the controller, if required. Code 90 indicates ice bin full, a cold bin probe will shut down the ice machine right after the next harvest is complete.
17. Replace and secure all the cabinet panels.
18. Discard all the ice from the start-up cycles, then clean and sanitize the ice storage bin according to the instructions provided.
Ice Machine Re-Start
At power up, in the ice making mode, the electronic control will monitor the conditions and operate in the following manner:
If the evaporator temperature is colder than the harvest termination temperature at start up, the water plate will open (lower).
If there is an obstruction preventing the water plate from closing, it will re-open (lower)
If the evaporator temperature is warmer than the harvest termination temperature and the water plate is open, it will close (raise).
Controls and Adjustments
On-Off Switch: Used to turn the ice machine on or off.
CAUTION: Switching the machine “off” does not de-energize all circuits. Always disconnect power before servicing.
Ice-Clean Switch: The “Ice” position signals the controller to provide full operation of the ice machine. The “Clean” position will exclude operation of the compressor and condenser fan motor
(air cooled models) and provide operation required for the cleaning procedure.
Defrost Button: Push this button anytime lowering the water plate and/or forcing the ice machine into the defrost mode is desired. The water plate will remain down for four minutes and then return to normal operation. Pushing the button again, while the plate is down, will immediately return the machine to normal operation.
Float Switch: Closes water inlet valve when water sump is full
Evaporator Probe: Provides evaporator temperature information to the control board to begin and end the defrost cycle. Adjust the left potentiometer on the control board to determine ice cube fullness. Turn CW to extend the freeze time and CCW to shorten it.
NOTE: Ice cubes should never be frozen completely full. A small dimple in each cube indicates a proper adjustment. Making cubes without a dimple will reduce ice machine capacity and may cause damage to the water plate and operating mechanism.
Bin Probe: This probe will sense contact with the ice, when the bin is full and turn off the ice machine. When ice is used and is no longer in contact the probe, it will signal the control to turn on the ice machine. When the ice machine is off due to a full bin, the code 90 indicator will be lit on the control board. Contact with ice should turn off the ice machine within one minute.
If adjustment is required, hold ice against the probe. Turn the right side potentiometer on the control board CCW to shut off the machine within one minute. CW adjustment is required if the ice machine shuts down, as if the bin is full, when ice has not contacted the probe.
Plate-Up Switch: This switch limits the upward travel of the water plate. It opens to de-energize the actuator motor, by way of an operator when its shaft is in the full up (closed) position.
This switch also provides a way for the controller to determine that the plate is blocked. When the plate is closing, the controller provides a time limit for this switch to open. If the time limit is exceeded, the controller will reopen the water plate to clear it. This will repeat until the surface is clear.
Plate-Down Switch: This switch limits the downward travel of the water plate. It opens to deenergize the actuator motor, by way of an operator when its shaft is in the full down (open) position.
Sequence of Operation
The following tables describe the general states and sequence of operation for the ice machine models in ice-making mode with an additional table depicting the status when the ice bin is full and the cleaning mode. The charts provide information about the inputs to the controller and the corresponding AC outputs associated with each part of the ice making cycle.

Sequence of Operation
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 until the water level switch indicates that the sump is full. The water pump will run as the water is filling the sump, If the water plate is open, it will close before the pump starts. The water solenoid valve will remain de-energized until the following cycle starts. No additional water will be introduced during the freeze cycle.
Freeze: The freeze cycle begins as the sump is filling with water. The water level in the sump will drop as the ice cubes are formed.
Lower: When the evaporator outlet reaches the set temperature point the machine will go into harvest. The water plate begins to open and the defrost valve is energized to allow hot gas to circulate through the evaporator. The evaporator warms to begin the ice harvest. The dump valve is also open at this time, to drain the remaining mineral laden water from the sump. When fully open, the water plate will stop.
Harvest: The evaporator continues to warm until the ice falls out onto the water plate and into the ice bin. When the evaporator reaches a pre-set temperature, indicating that all the ice has dropped out, the defrost valve is de-energized and the water plate begins to close.
Raise: The water solenoid valve will be energized, as the water plate closes, to begin filling the sump for the next ice-making cycle. When fully closed, the water plate will stop and the water pump will be energized. The evaporator cools and begins to remove heat from the water to make the next batch of ice.
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.
Cleaning Mode: All of the 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 12 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 water plate is not able to close due to ice remaining on the water plate surface, the plate will reopen until it is clear.
Shutdown-High Pressure: All models are provided with a high pressure cutoff, which interrupts power 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 will automatically reset, restoring power when the pressure drops. When this happens it is important to determine the cause of the high pressure and correct.
Maintenance and Service Information
Ice Machine Cleaning Procedure
96
It is recommended to perform this cleaning procedure a minimum of twice per year.
1. While the ice machine is operating, wait until the ice falls out of the evaporator and the water plate fully returns to the up position. Turn the machine off and empty the storage bin. Move the Ice-Clean Switch to the “Clean” position and turn the ice machine on.
2. While the water plate is filling pour 3 fl. oz. (90 ML) of Kold-Draft nickel-safe ice machine cleaner (Kold-Draft part no. 500023) into the water sump though the opening along its front edge.
3. The cleaning solution will circulate for 20 minutes and then drain. The sump will fill again, with the water circulating and then drain. This will repeat 3 more times, to be sure all the cleaning solution is rinsed out of the machine and then stop. When this process is complete, turn the machine off.
4. Mix a sanitizing solution containing 0.5 ounce (15 ML) 5-1/4% sodium hypochlorite (household bleach or equivalent) and 1 gallon (3.8 liter) warm clean water.
5. Pour the sanitizing solution into the sump. Leaving the Ice-Clean Switch in the “Clean” position turn the machine on.
6. The sanitizing solution will circulate for 20 minutes and then drain. The sump will fill again, with the water circulating and then drain. This will repeat 2 more times, to be sure all the sanitizing solution is rinsed out of the machine and then stop.
7. While these solutions are circulating in the ice machine, clean and sanitize all accessible surfaces of the ice machine and bin. Mix a cleaning solution as follows: 8 tablespoons (1/2 cup) (96g) baking soda and 1 gallon (3.8 liter) of warm clean water. Mix a sanitizing solution as follows: 2 teaspoon (10 ML) 5-1/4% sodium hypochlorite and 1 gallon (3.8 liter) of warm clean water. Use clean towels to apply these solutions and rinse well when done.
8. After all cleaning, sanitizing and rinsing has been completed turn the machine off. Move the
Ice-Clean Switch to the “Ice” position. Check for proper operation of the machine and dispose of the first batch of ice.
Cleaning Mode Start Up
At power up in the wash mode the electronic control will monitor the following criteria:
If the water plate is not in the full up (closed) position at start up, the controller will close the plate.
If there is ice on the surface of the water plate, preventing it from closing, the controller will reopen the plate to clear it.
Storage and Winterization
Clean and sanitize the ice machine.
Disconnect the electric power supply.
Disconnect water and drain lines.
Remove and empty the water sump.
Open water valve and dump valve and blow compressed air through all lines.
