DRAINS
•Separate drains must be provided for each evaporator section of each ice maker and ice bin. An
additional condenser drain is required for any liquid cooled ice maker, when the condenser coolant
will not be re-circulated.
•The size of the drain tubing must never be reduced along its length.
•Make sure that the building drain system can accommodate all the drain water from the ice
machine operation.
•Individual drains must never 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 or
back-siphonage of drain water into the ice maker or ice bin.
•Drain lines must be installed with a minimum drop of 2.5 cm per meter run (.3 inch drop per foot
run).
•Ice machine and bin drains may be insulated to prevent condensation.
COOLING TOWER APPLICATION
•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 design
a cooling tower application for an ice machine.
•Coolant entering the condenser must not exceed 32.2°C (90°F).
•Coolant exiting the condenser must not exceed 43.3°C (110°F).

4"
" ""
"
•Allow for a minimum pressure drop of 48 kPa (7 psig) 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.
POTABLE WATER SUPPLY
There are no specific requirements for water treatment provided that the water is potable, not laden with
sediment and does not exhibit residual chlorine level greater than 0.2 ppm. The use of water treatment,
however, may increase the intervals between cleaning operations. Do not connect the ice machine to a hot
water supply line. Insulate the water line from sources of heat or to prevent condensation.
NOTE - Purge all water supply lines before connecting them to the ice machine.
CAUTION
HIGH RESIDUAL CHLORINE (MORE THAN 0.2 PPM) CAN CAUSE CORROSION OF ICE MAKER
COMPONENTS AND EVEN THE 300 SERIES STAINLESS STEEL FRAME AND SKIN PANELS. HIGH
CHLORINE LEVELS MUST BE REDUCED, IN THE ICE MAKER WATER SUPPLY, TO PROTECT
THE EQUIPMENT AND PRESERVE THE PRODUCT WARRANTY.
Please contact your local water conditioning expert for recommendations, about your specific
water supply, or consult the factory.
A minimum 0.2 MPa (30 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.
•Minimum water temperature 7°C (45°F) Maximum water temperature 32°C (90°F)
•Water temperatures higher than the recommended maximum will cause reduced capacity.
•Minimum water pressure 0.2 MPa (30 psig) Maximum water pressure 0.6 MPa (100 psig)
•If a water pressure regulator is used, the recommended setting is 0.2 MPa to 0.3 MPa (30 to 50
psig) dynamic.
WARNING
ALL KOLD-DRAFT MODELS ARE INTENDED TO BE INSTALLED WITH A PERMANENT
CONNECTION TO THE FIELD ELECTRICAL SUPPLY. DROP CORD CONNECTIONS SHOULD
NEVER BE USED WITH THIS EQUIPMENT.
ALWAYS BE SURE THE POWER SUPPLY IS THE SAME AS THE ICE MACHINE
SPECIFICATION. SEE THE ICE MACHINE ELECRICAL PLATE.
BRANCH CIRCUIT PROTECTION
PROPER PROTECTION MUST BE PROVIDED BY THE USE OF FUSES OR HACR TYPE CIRCUIT
BREAKERS. EACH ICE MAKER MUST BE CONNECTED TO A SEPARATE PROTECTED

="
" ""
"
CIRCUIT WITH NO OTHER LOADS. A FUSED DISCONNECT PROVIDED BY THE INSTALLER
AND INSTALLED ADJACENT TO EACH ICE MAKER IS RECOMMENDED AND MAY BE
REQUIRED BY LOCAL CODES.
Minimum ampacity does not indicate typical running current value. Refer to the equipment
electrical plate. Use the minimum ampacity value for sizing branch circuit conductors up to 8 meters
(26 feet) in length. For conductor length over 8 meters, increase the wire gauge as required.
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.

ASSEMBLY
•Remove the ice machine front-cover panel, top-cover panel and side-cover panels from the ice
machine frame.
•The ice storage bin surface must be level. Use minimum 150 mm (6”) ice storage bin leg
adjusters, or seal the bin directly to the floor using shims as required. Use an NSF certified
sealant to seal the bin to the floor. If there are gaps larger than 3 mm (1/8”) install a cove
molding around the bottom of the bin.
•If not provided, an opening must be cut in the bin top corresponding to the ice drop zone. Holes
are provided in the ice machine frame for the purpose of attaching the ice machine to the ice
storage bin. Use the fasteners provided or other suitable non-corroding fasteners for this purpose.
•Apply gasket material to the ice storage bin top. The gasket material must be
positioned at the outside edge of the ice machine frame.
•Carefully lift the ice machine and position it on the ice storage bin. Attach the ice machine
to the ice storage bin.
•Make all plumbing and electrical connections to the ice machine and ice storage bin.
•Remove all shipping materials from the ice machine including the water plate shipping strap.
•Install the bin level probe, into the ice storage bin. See the following images.
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 the there is no dimple for 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.

START-UP
•Be sure that the on-off switch is in the “OFF” position and the make ice-clean selector switch is in
the “CLEAN” position.
•Turn on the water supply and the electrical power and check all supply lines for leaks.
•Make sure all pump and water tank hoses are connected, then pour .5 liter of clean potable
water into the circulation system(s) to lubricate the pump seal.
•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. The water fill is complete when the top float is up against the ring. Observe that the water
valve is de-energized at this time and there are no water leaks from the hoses or water tank into the
drain pan.
•Pull down on the right side of the water plate, stretching the springs until 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. At this point, 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.
•Move the ice-clean switch to the “ICE” position and observe that the compressor and the fan
motor (air cooled only) begin to run. The refrigeration system operation should be checked and
adjusted during the first few cycles.
•Test the bin level control operation by holding ice against the probe. The ice maker should
read code 90 on the control board within 30 seconds then shut off after the cycle ends.
•All adjustments and Service should be referred to a qualified technician who has the
proper Service Manual.
•Make sure that the drain pan, ice deflectors and stacking chute (GB1060 models and stacked ice
machines only) are properly installed. Replace and secure all the cabinet panels.
•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.
•Complete and mail the registration certificate to the factory. Leave all instructions with the
owner/user.
•NOTE- Emphasize all cautionary information to prevent personal injury, property and/or
