4. Water Supply and Drain Connections
See Fig. 1
CAUTION
To prevent damage to the equipment, do not operate the icemaker when the
water supply is OFF, or if the pressure is below 10 PSIG (0.7 bar). Do not
run the icemaker until the proper water pressure is reached.
• Water supply inlet is 1/2" FPT.
Note: On water-cooled model, two water supply inlets are provided. One is the ice
making water inlet, and the other (1/2" FPT) is the cooling water inlet.
• A water supply line shut-off valve and drain valve should be installed. A minimum of 3/8"
OD copper tubing is recommended for the water supply lines.
• Water supply pressure should be a minimum of 10 PSIG (0.7 bar) and a maximum of 113
PSIG (7.5 bar). If the pressure exceeds 113 PSIG (7.5 bar), the use of a pressure reducing
valve is required.
• Drain outlet for icemaker dump is 3/4" FPT. The bin drain is 3/4" FPT. The icemaker drain
and the condenser drain piping connections must be made separately from the bin drain.
Note: On water-cooled model, a 1/2" FPT is provided for the condenser drain outlet.
• The drains must have 1/4" fall per foot (2 cm. per meter) on horizontal runs to get a good
flow.
• The drains should not be piped directly to the sewer system. An air gap of a minimum of
2 vertical inches ( 5 cm.) should be between the end of the drain pipe from the icemaker
or the ice bin and the floor drain.
• This icemaker should be installed in accordance with applicable national, state and local
regulations.
• A plumbing permit and services of a licensed plumber may be required in some areas.
• In some areas, a back flow preventer may be required in the cooling water circuit.
