CAUTION

To prevent damage to equipment, do not operate this icemaker when the water supply is OFF, or if the pressure is below 10 PSIG (0.7 bar). 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 water supply inlets are provided. One is the water supply inlet for icemaking, and the other (1/2" FPT) 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 (0.7 bar) and a maximum of 113 PSIG (7.5 bar). If the pressure exceeds 113 PSIG (7.5 bar), the use of a pressure reducing valve is required.

•Drain outlet for icemaker dump is 3/4" FPT.

Note: Water-cooled model also has a 1/2" FPT condenser drain outlet. Icemaker dump and condenser drain lines 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 and water-cooled condenser (if applicable) 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.

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