G. Water Supply and Drain Connections
See Fig. 9
To prevent damage to the pump assembly, do not operate the icemaker when
the water supply is OFF, or if the pressure is below 10 PSIG.
• Water supply inlet is 1/" female pipe thread (FPT).
• A water supply line shut-off valve and drain valve should be installed. A minimum of 1/"
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.
• Drain outlet for icemaker dump is 3/4" FPT. The drain for condensation is a 5/8" OD
pipe. The icemaker drain and the condensate drain piping connections must be made
separately from the bin drain.
• A vented tee connection is required for proper flow.
• The drains must have 1/4" fall per foot 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
 vertical inches should be between the end of the drain pipes and the floor drain. See
Fig. 9.
• The 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.
