Connect the water supply
Plumbing information:
•
The water supply connection is at the back panel,
50 Hz models have a single 3/4 gas BNF inlet water
connection and a connecting hose is supplied.
Note: New connecting hose is supplied do not re-
use old hose set.
•
A hand actuated valve within site of the machine is
required to isolate the unit when being serviced.
• The machine has a built-in back flow preventer
(an air gap between the end of the water inlet hose
and the top of the water), no additional back flow
preventer is needed.
Units that are built into a cabinet:
Include a loop or coil of tubing between the water
supply and the connection on the ice machine. When
the machine is pushed back into the cabinet the
tubing will coil and not kink.
Connection Information:
WARNING: connect to potable water supply only.
Important: Open the hand water valve to flush
water through the tubing before connecting to the
ice machine.
230 volt models: Connect cold potable water to the
3/4 gas fitting on the unit using the supplied hose.
Note: Do not use a piercing-type saddle valve to
connect to the building’s water supply. Valves of
that type restrict water flow and clog easily.
Connect the drain
The drain connection is at the back panel. The fitting
size is ¾ FPT. Connect rigid tubing to this fitting and
vent it at the machine, use an 8 inch or 200 mm
vertical tube for the vent.
Drain tubing must slope down from the ice machine
to the building drain and the slope must be at least ¼
inch per foot or 20 mm per meter. Insulating the drain
tubing will reduce condensation and is recommended
for environments that have high humidity. Due to
the potential for leaks, condensate pumps are not
recommended.
