FOR THE PLUMBER
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.
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 are two 3/4"
FPT drains at the back of the cabinet.
Drain lines are 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 each 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 drains, a separate
condenser drain must be installed.
Connect it to the 1/2" condenser drain
connection at the back of the cabinet.
