FOR THE PLUMBER
CONFORM TO ALL APPLICABLE CODES
Water Inlet
Air Cooled Models: Connect to a water supply
that is cold and potable. Use
3
8
" O.D. copper
tubing, and connect to the single
3
8
" male flare at
the back of the cabinet. This connection supplies
water to both ice making systems. 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 single 3
8
" FPT
condenser inlet at the back of the cabinet. This
connection supplies water to both water cooled
condensers. 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
one ¾" FPT gravity drain fitting at the back of the
cabinet (used or both ice making systems). A ¼
inch per foot fall is the minimum pitch for the drain
tubing. There MUST be a vent at the highest point
of the drain line, and the ideal drain receptacle is a
trapped and vented floor drain.
Use only ¾" rigid tubing.
Water Cooled Models: Install a separate drain
tube for the condenser discharge water. There is
one drain for both ice making systems. Connect it
to the ½" FPT condenser drain connection at the
back of the cabinet.
Storage Bin: Connect a separate gravity type
drain tube, similar to the air cooled drain. Insulation
of this drain line is recommended.
