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.

O.D. copper line, with a separate hand valve, to
the " FPT condenser inlet at the back of the

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
