For personal safety this unit must

 

be properly grounded.

 Installation

Ϯ

Selecting a Location 

Choose a location for the refrigerator/freezer that will provide a 

clearance  of 4 in. at the top, 8 in. at the rear and 3 in. at each 

side.

Appropriate electrical power must be available. Locate the 

refrigerator/freezer within eight feet of the power outlet so that 

no extension cord is required. Attach the refrigerator/freezer to 

the facility’s electrical supply as directed by the 

National Electrical code Article 440.

 Figure 3. NEMA Plugs and Receptacles

Leveling the Unit 

The refrigerator/freezer must be level in order to provide 

adequate condensate drainage as well as proper door 

alignment and operation. The refrigerator

/freezer

 should be in 

its final operating location and set so that it is firmly positioned 

on the floor. 

Locate the two front leveling legs taped among the packing 

materials. Screw these legs into the front holes on the bottom 

of the freezer. The back of the 

refrigerator/freezer 

rests on two 

fixed supports. Adjust the front legs enough to lift the cabinet 

up off of the floor. Place a leveling tool on top of the 

refrigerator/

freezer first side to side, then front to back. Turn leg 

counter clockwise to raise a corner. 

Wiring 

General purpose units use 15 or 20 amp power cords. They are 

rated for 115 volts, AC, 60 Hz. Do not use extension cords, and 

always use a three prong grounded wall outlet. Figure 

3

 shows 

standard NE service cord plugs and wall outlets used for 

our

 

refrigerators and freezers.
