Installation: Water and Drain
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.
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 is required 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 water level and cannot
siphon).
2. Connect a drain tube the drain fitting. If water
cooled, the drain tubes must be run separately.
The bin drain fitting is 3/4" FPT, and it is plastic. Do
not overheat..
· 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). All drains are
gravity, and must have a minimum fall of 1/4"
per foot of horizontal run.
· Maintain the air gap required by local code
between the end of the drain tubes and the
building drain receptacle.
· Drain tubing should be insulated to prevent
condensation from forming on the tubing.
3. Water cooled models have a separate 3/8" FPT
fitting for condenser water inlet. Do not filter water
to this connection. The condenser drain is 1/2"
FPT and does not need a vent.
