About the controls with
numbered settings.
NOTE: The refrigerator is shipped with protective film covering the temperature controls.
If this film was not removed during installation, remove it now.
Initially, set the refrigerator control at 5 and the freezer control at 5 and allow 24 hours
for the temperature to stabilize.
Several adjustments may be required. Adjust the controls one increment at a time, and
allow 24 hours after each adjustment for the refrigerator to reach the temperature you
have set.
Setting either or both controls to 0 stops cooling in both the refrigerator and freezer
compartments, but does not shut off electrical power to the refrigerator.
Performance Air Flow System
The Performance Air Flow System is designed to
maximize temperature control in the refrigerator
and freezer compartments. This unique special
feature consists of the Air Tower along the back
6
wall of the refrigerator and the Air Tunnel on the
bottom portion of the freezer rear wall. Placing
food in front of the louvers on these components
will not affect performance.
