CAUTION

To prevent damage to the equipment, do not operate this 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.

•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" nominal copper water 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" nominal hard pipe.

•Drain outlets are 3/4" FPT.

•Drain lines must have 1/4" fall per foot (2 cm per 1 m) on horizontal runs to get a 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 the floor drain.

•This 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.
