See Fig. 9

CAUTION

To prevent damage to 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.

• Water supply inlet is 1/2" female pipe thread (FPT).

Note: On water-cooled model, two 1/2" 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 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 condensation drain line(s) must be run separately from the storage bin/dispenser unit drain line.

Note: Water-cooled model also has a 3/8" FPT condenser drain outlet. Drain line must be run separately.

•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 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, the condensation drain, the storage bin/dispenser unit, and the water-cooled condenser (if applicable) 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.

•Water-Cooled Model Only: In some areas, a back flow preventer may be required in the cooling water circuit.
