CU50
Service Manual
Specifications
This ice machine is designed to be used in a
controlled environment. It can be used in a wide
variety of environmental conditions and under
limited conditions (see user manual), outdoors, but
there are limits. Use outside of the listed limitations
is misuse and will void the warranty.
Air temperature limits:
The ice machine will operate adequately within the
limits, but functions best in temperatures between
70 and 80 degrees F.
• Minimum – 50 degrees F. (10°C)
• Maximum – 100 degrees F. (38°C)
Water temperature limits:
• Minimum – 40 degrees F. (4.5°C)
• Maximum – 100 degrees F. (38°C)
Water pressure limits:
• Minimum – 20 psi (1.4 bar)
• Maximum – 80 psi (5.5 bar)
Because the ice machine is making a food product,
the water supply to the ice machine must be
potable, or fit for human consumption.
Electrical
• 115 volt, 60 Hz. Plug into dedicated 15 amp
circuit.
• Power consumption: 275 - 400 Watts. Varies
during Freeze and Harvest cycles.
Voltage limits:
• Minimum - 104 volts
• Maximum – 126 volts
Models: There are two models, all air cooled:
• CU50PA-1 – Pump model
• CU50GA-1 – Gravity drain model
Options:
Kickplate Extension: In some situations the leg
levelers will be extended enough to become visible.
A kit to extend the kickplate over the legs is KKPF.
Cabinet Stability: In some free standing
installations it may be prudent to add a bracket that
secures the back of the cabinet to a wall. That kit
number is KATB.
Drain Conversion:
A gravity drain model can be converted to a drain
pump model by installing a drain pump kit. The
drain pump kit consists of a drain pump, wiring
harness and associated tubing. The kit number is
A39462-021.
Warranty Information
Warranty information is supplied separately from
this manual. Refer to it for coverage. In general, the
warranty covers defects in materials or workmanship
and does not cover corrections of installation errors
or maintenance.
