•
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.
•
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.
