Installation

Note: The building drain inlet must be lower than
the drain outlets at the back of the ice machine.
The water supply must have a hand shut off valve
accessible when the unit is installed.
For the Plumber
1. Connect cold potable water to the 3/8" FPT inlet
water fitting, located below the upper back panel.
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 water. No back flow preventer is
required in the potable water line. This is provided by
the sump inlet, which is above the sump water level
which then cannot be siphoned.
2. Connect a drain tube to the drain fitting. Drain
tubes for a water cooled machine should 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 feet or more. All drains are
gravity and must have a minimum fall of 1/4'' per
foot of horizontal run.
3. Maintain the air gap required by local code
between the end of the drain to, and the building
drain receptacle.
• Drain tubing should be insulated to prevent
condensation from forming on the tubing.
4. 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.
Water Cooled and Recirculating Systems Note
Water cooled equipment may be connected to a
closed loop recirculating system. See the pressure
limits on page 2.
The included water regulating valve will vary the
amount of coolant needed to maintain a constant
discharge pressure. Higher coolant temperatures
will result in increased coolant flow to maintain the
discharge pressure set point.
For the Electrician
This is a cord-connected unit and must be on a
separate single phase power supply. Check the name
plate for the correct voltage. The maximum fuse size
for this circuit should be 15 A, per the nameplate use
fuses or HACR circuit breaker.
Follow all local codes. This unit must be
grounded. Do not use extension cords and
do not disable or bypass the ground pin on
electrical plug.
Note: Electrical outlets can become worn and the
connection can then be erratic. Have it replaced if it is
loose.
After utility connections
1. Level the cabinet, use the leg levelers on the end
of the legs to adjust to cabinet height. Legs should
have been installed when the unit was unpacked.
2. Wash the bin and hood. If desired, the interior of
the bin could be sanitized.
3. Locate the scoop, wash it and have it available for
use when needed.
