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 flow preventer
(an air gap between the water’s entry point and
the top of the reservoir water), no additional back
flow preventer is needed.
•
Water flow rate into machine is .125 gal/min
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:
Important: connect to potable water supply only.
Open the hand water valve to flush 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 fittings 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
fittings.
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.
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 drain must be vented if there is a long
horizontal run 5 feet or more. All drains are
gravity and must have a minimum fall of 1/4’’ per
foot of horizontal run.
1.
Connect rigid tubing to this fitting 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.
