Connect the water supply
Plumbing information:
• The water supply connection is at the back panel. It
is a 5’ (1.5 meter) 1/4 inch (6.35 mm) OD plastic tube.
• A hand actuated valve within site of the machine is
required to isolate the unit when it’s being serviced.
• The machine has a built-in back ow preventer (an
air gap between the end of the water inlet hose and
the top of the reservoir water), no additional back ow
preventer is needed.
• Water ow rate into machine is .25 GPM / .94 LPM.
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 ush
water through the connection point before
connecting to the ice machine.
1. Cut cable ties securing hose and power cord to
unit.
2. Connect to cold, potable water using the
necessary adapters for the 1/4 inch OD plastic
tube.
• If using compression ttings they require a ferrule or
sleeve and insert.
• A female 3/8 compression adapter x 1/4 OD
compression allows connection to a typical 3/8 OD
compression angle valve.
• Another connection method is by quick connect
ttings.
Note: Do not use a piercing-type saddle valve to
connect to the building’s water supply. Valves of
that type restrict water ow and clog easily.
Connect the drain
The drain connection is at the back panel. The tting
size is ¾ FPT.
1. Connect rigid tubing to this tting and vent it at the
machine, use an 8 inch or 200 mm vertical tube
for the vent.
2. Slope drain tubing 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.
3. Insulate the drain tubing to reduce condensation
and is recommended for environments that have
high humidity.
Due to the potential for leaks, condensate pumps are
not recommended.
