ICE CUBER INSTALLATION
Warning:
• Do not operate equipment that has been damaged.
• Refer all maintenance to qualified personnel.
• 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.
• Always securely attach individual component sections together. (Bins, Bagging Machines,
Dispensers, Crushers, Ice Machines etc.
• 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. When receiving the unit please inspect it for physical
damage. If damage is found:
1. Have carrier note the damage on the bill of lading.
2. File a damage claim report with the carrier immediately.
3. Call Kold-Draft with your claim number to arrange replacement or repair.

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

• 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.
