INSTALLATION 

 

UNCRATING

 – 

This unit comes with an optional roller base so you 

can unpack it in an open area and then place it on the roller base 

to move to its normal location. Remove the wooden planks or 

skid as shown. These units come with a caster platform (or roller 

base). To place the unit on the roller base have one person tilt 

the machine forward and hold it while a second person slides the 

roller base in from the back. Note that the side without a top lip 

goes towards the front of the unit. Once it is in as far as it will go, 

have the second person lock the rear wheels and hold the base 

firmly in place while the first person tilts the machine up and onto the roller base, pushing it 

back until all 4 corners are on the base. You can now unlock the rear wheels and move the unit 

to its final location. The freezer  should be placed as close as possible to a dedicated power 

outlet so an extension cord will not be needed. This unit requires a 

minimum of 4 inches of air 

flow space in back and 3 inches on the sides and top.

 Once the unit is in place, the rear casters 

on the roller base should be locked to prevent inadvertent movement.  

 

LEVELING 

 Once the unit is in place (either on or off of the roller base) you can level it with the 

screw-type adjustable leveling legs on the front corners of the unit.  Turn counterclockwise to 

raise the corner; turn clockwise to lower it. The unit may have a slight tilt from front to back 

after the legs are installed.  This is acceptable and is actually recommended. 

 

POWER SOURCE – The supply circuit to this cabinet 

must conform to all National and Local Electrical 

Codes.  Consult the cabinet Serial-Data plate for 

voltage, cycle, phase, and amp requirements before 

making connection.   VOLTAGE SHOULD NOT VARY 

MORE THAN 5% FROM SERIAL PLATE RATINGS.  A 

separate circuit is recommended to prevent possible 

loss of product due to over-loading or failure of 

other equipment on the same circuit.  PROTECT THE CIRCUIT WITH A 20 AMP DELAY-TYPE FUSE 

OR CIRCUIT BREAKER.  Do not use an extension cord.  Be sure your unit is properly grounded.  

Use the 3-prong plug provided into a 3-prong grounded outlet. 

(Only this method complies with national electrical codes, local 

codes and ordinances.)  Unless the above grounding method is 

followed, you are not protected against severe or lethal shock 

in the event of a short circuit of an electrical component or 

wiring of the unit. 

 

STARTING – There are no compressor shipping bolts to loosen 

or valves to open.  All that is necessary after the unit has been 

placed on the roller base and leveled is to plug the service cord 

into an electrical outlet  When starting this new appliance, 

allow the cabinet to operate a minimum of eight hours or until
