Specifications

This ice machine is designed to be used indoors, 

in a controlled environment, and under limited 

conditions (see page 1), outdoors. It can be used 

in a wide variety of environmental conditions, 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. (10ºC)
•  Maximum – 100 degrees F. (38ºC)

Water temperature limits:

•  Minimum – 40 degrees F. (4.5ºC)
•  Maximum – 100 degrees F. (38ºC)

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.

Other:

Indoor use and kickplate: You may remove the 

stainless steel kickplate cover from the unit when 

installed indoors. Leave the plastic kickplate on the 

unit.

Note:The stainless steel kickplate cover must 

remain on the unit when the unit is installed 

outdoors.

Electrical voltage limits:

•  Minimum – 104 volts
•  Maximum – 126 volts

Models

•  CU50GA-1A - gravity drain
•  CU50PA-1A - pump drain

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 part number is 

A39462-021

.
