UNPACKING

1. Uncrate machine and/or bin by removing the staples from around the bottom of cardboard crate and
lift off.

Series 322 Ice Cube Machine Installation Instructions

LEVELING

If legs are used, adjust the leveling legs of the storage bin until the unit is level and all four (4) legs are in
sold contact with the floor. Leveling is very important to obtain proper draining and to maintain the proper
level in the water pump pan of the ice cuber.

Note: If the bin is to be installed flush to the floor, the bin must be sealed to floor with an approved mastic
such as Dow R.T.V. #732, 734, or G.E. #102, 108. This is an N.S.F. requirement and is the responsibility
of the installer.

UNIT LOCATION

1. Allow at least a minimum of six inches at the rear and side of the ice machine for proper air RHP
circulation.

2. This unit has been designed to be installed in an indoor location which is clean and which can be
adequately ventilated. The air and water temperatures should never exceed 100°F or fall below
50°F. (Temperatures above 100°F will cut the ice making capacity below an economical level.
Temperatures below 50°F will cause a malfunction of thermostatic sensors.)

3. The unit should be located where air circulation is not restricted. The unit should not be located
near a kitchen grill. Air which contains grease vapors will deposit grease on the condenser. The
condenser should always be kept clean.

UNIT SET-UP

1. Take off front panel of machine and remove hardware bag and service manual envelope.

2. Mount the ice maker to the top of the ice storage bin or adapter in the proper position over the ice
drop opening. The ice maker must then be sealed both on the outside and the inside bottom edges
with an approved N.S.F. mastic such as Dow R.T.V. #732, 734, or G.E. R.T.V. #102, 108. This is an
N.S.F. requirement and the responsibility of the installer.

3. Remove shipping tape from evaporator curtains.

MAKE ELECTRICAL POWER SUPPLY CONNECTION

Requirements: 115V/60 Hz 1 ph., 230V/60 Hz. 1 ph., or 220V/50 Hz. 1 ph when used.

Refer to serial plate for minimum circuit ampacity and maximum time delay fuse size.

All wiring must conform to national and local electrical codes.

MAKE PLUMBING CONNECTIONS

Water supply – (install per local codes) (see Figure 4).

The water inlet connection to the unit is a 3/8” male flare connection located at the rear of the ice
machine.

Warning - If the water pressure exceeds 50 pounds, a water pressure regulator should be

installed in the water inlet line between the water shut-off valve and the strainer.

Install a reducer fitting on the shut-off valve to accommodate the water stainer, which is supplied with
each ice machine and MUST be used. This is very important for cleaning. Connect either 3/8” or 1/2”
copper tubing between the water inlet fitting of the ice machine and the water strainer.

For water cooled units

Two water inlet connections are provided. One is for the ice making (evaporator) section which is located
on the back of the machine and is a 3/8” flared connection. The other is for the water cooled condenser.
