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. Connect 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:
Connect a
rigid
drain tube to
the
3
4
" FPT drain fitting at the back of the cabinet.
The drain is a gravity type, and ¼ inch per foot fall
is the minimum 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
: Connect a separate drain
line to the
1
2
" condenser drain connection at the
back of the cabinet. Do not vent this drain.
Storage Bin
: Connect a
separate
gravity type
drain to the ice storage bin drain. Vent this drain if
there is a long horizontal run from the bin to the
floor drain. Insulation of this drain line is
recommended.
