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'' male
flare behind the lower 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 reservoir seat, which is above the reservoir water
level and 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.
• 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.
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 is1/2'' FPT and does not
need a vent.
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.
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.
