FOR THE PLUMBER

CONFORM TO ALL APPLICABLE CODES

Water Inlet

Air Cooled Models: Use

3

" O.D. copper tubing to

connect cold potable water to the

3

" 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

"

O.D. copper line, with a separate hand valve, to
the

3

" 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.
