FOR THE PLUMBER

Water Inlet
Air Cooled Models: The recommended water
supply is clean, cold water. Use 3/8" O.D. copper
tubing, connect to the 3/8" male flare 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: A separate 3/8" O.D.
copper line is recommended, with a separate hand
valve to control it. It is connected to a 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.

DRAIN DRAIN
Drains
Air Cooled Models: There is one 3/4" FPT drain
at the back of the cabinet, the drain line is of the
gravity type, and 1/4 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 3/4" rigid tubing.
Water Cooled Models : In addition to the above
mentioned drain, a separate condenser drain must
be installed. Connect it to the 1/2" condenser
drain connection at the back of the cabinet.
Storage Bin : A separate gravity type drain needs
to be run, similar to the air cooled drain. Insulation
of this drain line is recommended.
