7. Water Supply and Drain Connections
See Fig. 7
• External filters or strainers may be required depending on the water quality.
• 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 3/8"
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 icemaking is 3/4" FPT. The icemaker drain piping connections must be
made separately from the bin drain piping connections.
• 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
2 vertical inches should be between the end of the drain pipe from the icemaker or the ice
bin and the floor drain.
• A plumbing permit and services of a licensed plumber may be required in some areas.
