Choose a location near a grounded electrical outlet. Do not install the refrigerator-freezer where the
temperature will drop below 55°F (13°C) or rise above 110°F (43°C). The compressor will not be
able to maintain proper temperatures inside the refrigerator-freezer.
Allow adequate space around the unit for good air circulation.
A minimum of 3/8 inch (10 mm)
space on the sides and top and 1 inch (25 mm) space at the back of the refrigerator-freezer is
required for adequate air circulation.
Do not block the toe grille on the lower front of the refrigerator-freezer. Sufficient air circulation is
essential for proper operation of the unit.
Note:
The exterior walls of the refrigerator may become quite warm as the compressor works to
transfer heat from the interior. Temperatures as much as 30°F (-1°C) warmer than room
temperature can be expected. It is particular in hotter climates to allow adequate space for air
circulation around the refrigerator.
ELECTRICAL
Check the proposed outlet to be used to insure that the voltage, phase, and current carrying
capacity of the circuit from the electrical panel correspond to the requirements of the cabinet.
NEVER
use an extension cord or adapter plug to wire any unit. Refer to the serial tag for all
pertinent electrical information.
The refrigerator-freezer must be plugged into its own 115 volt, 60 Hz, single phase outlet. The
power cord of the refrigerator is equipped with a three-prong grounding plug for protection against
shock hazards. It must be plugged into a properly grounded three-prong receptacle. The
receptacles must be installed in accordance with local codes and ordinances.
If voltage varies by more than 10%, refrigerator performance may be affected. Operating the
refrigerator with insufficient power can damage the compressor.
To prevent the refrigerator from being accidentally turned off, do not plug the unit into an outlet
controlled by a wall switch or pull cord.
Do not pinch, knot or bend the cord in any manner.
Observe all Warning Labels. Disconnect power supply to eliminate injury from electrical
shock or moving parts when servicing equipment.
OPERATION
Cool Down Period
For safe storage of product, allow a minimum of 12 hours for the refrigerator to cool down
completely. The refrigerator will run continuously for the first several hours.
Temperature Control
The temperature control is located inside the refrigerator. When first energizing the refrigerator-
freezer, move the refrigerator and freezer controls to ▼ which is the recommended initial setting.
Adjust the controls after 24 hours if required. Adjust the temperatures gradually. Move the control in
small increments and allow the temperature to stabilize between setting changes.
For colder temperatures, adjust the control knob towards Colder.
For warmer temperatures , adjust the control knob towards Cold.
Turning the refrigerator control will change temperatures in both the refrigerator and the freezer. If
the temperature control is turned to a colder setting, the freezer control may require adjustment to a
warmer setting. Turning the freezer temperature control will change only the freezer temperature.
To maintain required temperatures, a fan circulates air in the refrigerator and freezer compartments.
Do not block cold air vents with product.
