All models require an adequate potable water
supply and a gravity drain. The recommendations
for tubing are:
•
Water supply to be
3
8
" OD.
•
Drain to be
3
4
" OD.
Note: When replacing a prior ice machine, do not
take a short cut and reuse the old inlet and drain
system. INSTALL A NEW SYSTEM.
Supply:
Air cooled models have 1 water supply connection,
a
3
8
" male flare at the back of the cabinet. Connect
to cold potable water that has adequate pressure.
Note: Using water supply tubing smaller than
3
8
"
will cause severe operational issues.
Water Filters:
The water filters must flow at least
2.7 GPM
or they
will cause severe operational issues. Check with
the filter manufacturer. When replacing a prior ice
machine, do NOT assume that the water flow
capacity of the filter will be adequate.
All Drain Tubing Material must be RIGID.
Flexible tubing will eventually cause a restricted
drain.
Drain:
Air cooled models have 1 gravity drain connection,
a
3
4
" FPT fitting at the back of the cabinet. Use only
RIGID TUBING. Flexible tubing may be easily
kinked or become cracked.
The drain tube must be vented at the back of the
cabinet. Use an 18" high vent.
The ice storage bin will have a drain out the back or
base, depending upon the model.
The drain for the ice machine and the ice storage
bin must be SEPARATE or the ice machine’s drain
water may run into the bin and MELT THE ICE.
Insulation is recommended for the ice machine
reservoir and bin drains.
