All models require an adequate potable water
supply, a condenser water supply and a gravity
drain. The recommendations for tubing are:
•
Potable water supply to be
3
8
" OD.
•
Condenser water supply to be ½" OD.
•
Reservoir drain to be
3
4
" OD and vented
•
Condenser drain to be ½” OD, non vented
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:
All models have 1 potable 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.
The water cooled condenser requires an additional
supply line.
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. Filtering the
condenser water supply is not recommended.
All Drain Tubing Material must be RIGID.
Flexible tubing will eventually kink and cause a
restricted drain.
Drain:
Connect a
3
4
" drain tube to the reservoir drain
fitting at the back of the cabinet. Use only RIGID
TUBING. Flexible tubing may be easily kinked or
become cracked.
The reservoir drain tube must be vented at the
back of the cabinet. Use an 18" high vent.
Connect a ½” drain tube to the condenser drain at
the back of the cabinet. Do not vent this drain.
The ice storage bin will have a drain out the back
or base, depending upon the model.
The drains 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.
