E. Water Supply and Drain Connections
See Fig. 2
CAUTION
To prevent damage to equipment, do not operate this 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" female pipe thread (FPT).
Note: On water-cooled model, two water supply inlets are provided. One is the water
supply inlet for icemaking, and the other (1/2" FPT) is for the water-cooled
condenser.
• 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.
Note: Water-cooled model also has a 1/2" FPT condenser drain outlet. Icemaker dump
and condenser drain lines must be run separately.
• Drain lines must have 1/4" fall per foot (2 cm per 1 m) on horizontal runs to get good
flow. A vented tee connection is also required for proper flow.
• Drain lines 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 pipes from the
icemaker and water-cooled condenser (if applicable) 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.
• Water-Cooled Model Only: A back flow preventer may be required in the cooling water
circuit in some areas.
