Fully Electronic Defrost System
The Control Board adapts the compressor run time
between defrosts to achieve optimum defrost intervals
by monitoring the length of time the defrost heater is on.
After initial power up, defrost interval is 4 hours
compressor run time. Defrost occurs immediately after
the 4 hours. Once unit is ready to defrost there is a 4
minute wait time prior to the beginning of the defrost
cycle.
Serial Number Location
The model number and serial number are located on the
data plate. The data plate is located in the refrigerator
compartment on the upper left side.
Installation
Location
Do not install refrigerator near oven, radiator or other
heat source. If this is not possible, shield the refrigerator
with cabinet material.
Do not install where temperature falls below 55° F or
rises above 110° F. Malfunction may occur at this
temperature.
Refrigerator is designed for indoor household application
only.
Measuring the Opening
When installing your refrigerator, allow ½” space at top
and ½” space behind machine compartment cover
(located in the rear) for proper air circulation. If the
refrigerator is placed with the door hinge side against a
wall, you may want to allow additional space so the door
can be opened wider.
Subflooring or floor coverings (i.e. carpet, tile, wood
floors, rugs) may make your opening smaller than
anticipated.
Some clearance may be gained by using the leveling
procedure under Leveling.
IMPORTANT: If refrigerator is to be installed into a
recess where the top of the refrigerator
is completely covered, use dimensions
from floor to top of hinge cap to verify
proper clearance.
Leveling
CAUTION
Use care when leveling the refrigerator to avoid
damaging the floor or refrigerator.
To enhance the appearance and maintain performance,
the refrigerator should be level.
NOTE: Complete any required door reversal, panel
installation and/or a water supply connection,
before leveling.
1. Remove the toe grille.
2. Turn the front adjustment screws clockwise to raise
and counterclockwise to lower the front of the
refrigerator.
3. Turn the rear adjustment screws clockwise to raise
and counterclockwise to lower the rear of the
refrigerator.
4. Using a level, make sure front of refrigerator is ¼” or
½ bubble higher than back of refrigerator and that the
refrigerator is level from side to side.
5. If required, correct rocking of refrigerator by turning
rear adjustment screw clockwise to raise rocking
corner.
Rear Adjustment Screws
Front Adjustment Screws
Leveling doors
1. Turn front adjustment screw clockwise to raise front
corner of door.
2. If one refrigerator door has reached the limit of its
adjustment range and doors are still not level, raise
or lower the opposite door by turning roller
adjustment screw counterclockwise.
3. Check with level to verify ¼” tilt to the back for proper
door closure.
4. If refrigerator is aligned and stable, replace toe grille.

Operating Sounds
Improvements in refrigeration design may produce sounds in your new refrigerator that are different or were not
present in an older model. These improvements were made to create a refrigerator that is better at preserving food,
is more energy efficient, and is quieter overall. Because new units run quieter, sounds may be detected that were
present in older units, but were masked by higher sound levels. Many of these sounds are normal. Please note that
the surfaces adjacent to a refrigerator, such as hard walls, floors and cabinetry may make these sounds seem even
louder. The following are some of the normal sounds that may be noticed in a new refrigerator.
SOUND POSSIBLE CAUSE SOLUTION
