Section 1

To the Installer

These machines are designed for indoor use only.

DO NOT

install the machine in an area where

a water jet could be used. Failure to follow this

instruction may result in serious electrical shock.

Water Connections

(Water Cooled Units Only)

An adequate cold water supply must be provided with

a hand shut-off valve. On the underside rear of the

base pan, two 3/8” I.P.S. (for single head units) or two

1/2” I.P.S. (for double head units) water connections

for inlet and outlet have been provided for easy

hook-up. 1/2” inside diameter water lines should be

connected to the machine. (Flexible lines are

recommended, if local codes permit.) Depending on

local water conditions, it may be advisable to install a

water strainer to prevent foreign substances from

clogging the automatic water valve. There will be only

one water “in” and one water “out” connection for both

single head and double head units. DO NOT install a

hand shut-off valve on the water “out” line! Water

should always flow in this order: first, through the

automatic water valve; second, through the

condenser; and third, through the outlet fitting to an

open trap drain.

Air Cooled Units

The model 702 requires a minimum of 6” (152 mm) of

clearance around both sides of the freezer. Install the

deflector on the right side of the unit, and place the

back of the unit against the wall to prevent recirculation

of warm air. The models 741 and 772 require a

minimum of 3” (76 mm) of clearance around all sides.

Install the deflector provided. Failure to allow adequate

clearance can reduce the refrigeration capacity of the

freezers and possibly cause permanent damage to the

compressors.

Electrical Connections

Each freezer requires one power supply for each data

label. Check the data label on the freezer for fuse, wire

ampacity and electrical specifications. Refer to the

wiring diagram provided inside of the electrical box, for

proper power connections.

In the United States, this equipment is intended to be

installed in accordance with the National Electrical

Code (NEC), ANSI/NFPA 70--1987. The purpose of

the NEC code is the practical safeguarding of persons

and property from hazards arising from the use of

electricity. This code contains provisions considered

necessary for safety. Compliance therewith and

proper maintenance will result in an installation

essentially free from hazard!

In all other areas of the world, equipment should be

installed in accordance with the existing local codes.

Please contact your local authorities.

Stationary appliances which are not equipped with a

power cord and a plug or other device to disconnect

the appliance from the power source must have an

all--pole disconnecting device with a contact gap of at

least 3 mm installed in the external installation.

CAUTION: This machine must be properly

grounded! Failure to do so can result in severe

personal injury from electrical shock!
