Installation
For The Plumber
1. Connect cold potable water to the 3/8" male
flare at the 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 tube
from the inlet water valve has an air break in it, is
above the reservoir wall and cannot siphon).
2. Connect a drain tube to each drain. The drain
tubes from these connections must be run
separately. There are two connections, one is the
bin drain and the other is the reservoir drain. The
reservoir drain is a 3/4" F.P.T. brass fitting.
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 reservoir drain
must be vented and not connected to the bin drain.
All drains are gravity, and must have a minimum
fall of 1/4" per foot of horizontal run. The water
cooled condenser drain is not 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.
