CONFORM TO ALL APPLICABLE CODES
Water Inlet
Air Cooled Models: Connect a potable, cold water
supply to the 3/8" male flare at the back of the
cabinet. Install a hand valve near the machine to
control the water supply. 3/8" O.D. copper tubing is
recommended.
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
control it 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: There is one 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.
