Installation
For The Plumber
1. Connect cold potable water to the 3 ⁄
8
" male flare
at the top back of the cabinet. A water filter is
recommended. Flush the water line prior to
connecting to the ice machine.
If water cooled, connect a separate water inlet line
to the water cooled condenser inlet fitting. It should
also have a hand shut off valve.
A loop of copper tubing may be used between the
ice machine and the water supply. This will allow
the ice machine to be pulled out from its installed
location without disconnecting the water line. No
back-flow preventer should be needed in the inlet
potable water line because provision for that is
incorporated in this N.S.F. listed product (the float
seat is above the reservoir wall and cannot siphon).
Drain tube material must be rigid and meet local
code.
Traps in the bin drain line without vents ahead of
them will cause poor draining.
The bin drain must be vented if there is a long
horizontal run (5’ or more). The purge drain
must also be vented. All drains are gravity, and
must have a minimum fall of 1/4" per foot of
horizontal run. The water cooled condenser drain
should not be vented, and is routed separately.
Maintain the air gap required by local code
between the end of the drain tubes and the
building drain receptacle.
Note: Drain tubing should be insulated to prevent
condensation from forming on the tubing.

2. Connect a drain tube to each drain. The drain
tubes from these connections must be run
separately. There are two connections at the
back of the cabinet,
one is the bin drain
and the other is the
purge drain. Both
are
3 ⁄
4
" F.P.T. brass
fittings.
Note: The unit is designed for drain connections
on the outside of the cabinet. To connect the
drains inside would require the removal of the
drain fittings attached to the back panel, and field
fabricated drain tubes routed inside the base of the
unit.
