7. WATER SUPPLY AND DRAIN CONNECTIONS
- with Storage Bin See Fig. 9
- with Dispenser Unit See Fig. 10
IMPORTANT
To prevent damage to the pump assembly, do not operate the icemaker when
the water supply is OFF, or if the pressure is below 14.5 PSIG. 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 models, two water supply inlets are provided.
One is for the icemaker, and the other 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 14.5 PSIG and a maximum of 145 PSIG.
If the pressure exceeds 145 PSIG, the use of a pressure reducing valve is required.
• Drain outlet for icemaker water is 3/4" FPT. The drain for condensation is a 5/8" OD tube.
The icemaker drain and the condensation drain piping connections must be made sepa-
rately from the bin drain.
• 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.
• 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.
