About the controls on the refrigerator.
The control will look like the following:
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 allow 12–24 hours
for the temperature to stabilize.
Several adjustments may be required. Adjust the control one
increment at a time, and allow 12 hours after each adjustment for
the refrigerator to reach the temperature you have set.
Setting the controls to 0 stops cooling the refrigerator, but
does not shut off electrical power to the refrigerator.
Control settings will vary based on personal preferences, usage and
operating conditions and may require more than one adjustment.
