CONFORM TO ALL APPLICABLE CODES
Water Inlet
Air Cooled Models: Use 3 8" O.D. copper tubing to connect cold potable water to the 3 8" male flare fitting at the back of the cabinet. Install a hand valve near the machine to control the water supply. Water Treatment: In most areas, a water filter of some type will be useful. In areas where the water is highly concentrated with minerals the water should be tested by a water treatment specialist, and the recommendations of the specialist regarding filtration and/or treatment should be followed.
Water Cooled Models: Connect a separate 3 8" O.D. copper line, with a separate hand valve, to the 3 8" FPT condenser inlet at the back of the cabinet. The water pressure to all lines must always be above 20 PSIG, and below 80 PSIG.

Drains
Air Cooled Models: Connect a drain tube to the ¾" FPT drain at the back of the cabinet, the drain line is of the gravity type, and ¼ inch per foot fall is an acceptable pitch for the drain tubing. There should be a vent at the highest point of the drain line, and the ideal drain receptacle would be a trapped and vented floor drain.
Use only ¾" rigid tubing.
Water Cooled Models: In addition to the above mentioned drain, a separate condenser drain must be installed. Connect it to the ½" condenser drain connection at the back of the cabinet.
Storage Bin: Install a separate gravity type drain, similar to the air cooled drain. Insulation of this drain line is recommended.
