See Fig. 9
IMPORTANT
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. Do not run the icemaker
until the proper water pressure is reached.
• The icemaker must 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 supply inlet is 1/2" female pipe thread (FPT).
• A water supply line shut-off valve and drain valve should be installed. A minimum of
1/2" OD copper tubing is recommended for the water supply lines.
• Water supply pressure should be a minimum of 10 PSIG and a maximum of 113 PSIG. If
the pressure exceeds 113 PSIG, the use of a pressure reducing valve is required.
• The minimum recommended drain line is 3/4" OD hard pipe.
• Icemaker drain outlet is 3/4" FPT. Condensation drain outlet is a 5/8" OD stainless tube.
The icemaker and condensate drain line(s) must be run separately from the dispenser
unit/storage bin unit drain line.
• 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 required for proper flow.
• 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 pipes from the icemaker,
the condensation drain, the dispenser unit/storage bin and the floor drain. See Fig. 9.
