CABINET LOCATION:

 An air space of at least 1” (2.5 cm) must be maintained on all sides of the freezer. 

Do not locate the freezer in a warm unventilated room exceeding 86ºF (30ºC) and 55%RH; do not place 

freezer in direct sunlight; do not place freezer under or near heat range or heating vent. 

 

CABINET LEVELING:

 The freezer must be completely leveled side to side and front to back or slightly 

tilted front to back but never tilted forward. Once the freezer is placed in its final location, use a car-

penter level to level the freezer. Proper leveling of the freezer is important for the door closing and 

water drainage during the defrost cycle. There are two leg levelers in the front that can be adjusted. First, 

loosen the nuts using an adjustable wrench. Second, turn levelers counter-clockwise to raise the freezer, 

or clockwise to lower, until they reach the leveled position. Lastly, tighten the nuts again to lock the legs.

INSTALLATION INSTRUCTIONS    

• DO NOT USE AN EXTENSION CORD 
• DO NOT CUT, REMOVE OR BYPASS THE GROUNDING PRONG FROM THE PLUG 
• DO NOT PLUG FREEZER INTO AN OUTLET CONTROLLED BY A WALL SWITCH  
• ENSURE POWER CORD IS NOT CUT OR DAMAGED FROM PINCHING, KNOTTING, OR MISHANDLING

NOTICE: 

Failure to follow these instructions may void the warranty and/or cause loss of product.

All models require a 15 Amp dedicated and properly grounded 115V/60Hz/1Ph circuit 

with a NEMA 5-15P receptacle. Wiring should be sized according to the amperage        

rating stated on the serial plate. Failure to use a dedicated circuit may cause the circuit 

breaker to trip off and/or cause voltage drops. As a result, power to the freezer may be 

interrupted and freezing performance can be adversely affected which may cause equip-

ment damage and/or product loss. 

 

Voltage supply to the freezer must not vary more than ±10% of the nominal 115V, or performance may 

be  affected.  The  warranty  and  liability  does  not  cover  damage  resulting  from  excessive  voltage           

variations.

The anti-fog glass door has a protective film on the inner side. After the 

unit has been installed, peel and remove the protective film covering 

the inner glass surface. 

WARNING

  

These freezers MUST be installed on a dedicated grounded circuit protected with a 15 Amp circuit breaker 

or a 15 Amp time delay fuse. Do not remove ground prong. If the cord or plug is damaged, replace with the 

same type. Refrigeration and electrical work must be performed by a qualified technician. Failure to follow 

these instructions can result in death, fire, or electrical shock.
