CONFORM TO ALL APPLICABLE CODES
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.
Note: Back flow prevention for the potable water
supply is provided by the air gap between the float
valve orifice and the water reservoir overflow.
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.
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.
