•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
oThe 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:
•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.

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.

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 ⅛inch (3 mm) for “C”
models and ¼inch (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.
