Operation - Unique Classic UGP-175L UR W Owner's Manual

Your Unique freezer, like any battery-powered refrigerating appliance, requires diff erent care
than appliances plugged into an electric utility. Prudent operation is the key to extended service.
STARTING THE FREEZER
After the freezer has been properly connected to the 12V or 24V DC power source, the
compressor will automatically turn on and the cabinet will begin cooling. Allow the cabinet to cool
for at least 4 hours prior to adding foodstuff .
TEMPERATURE CONTROL
The temperature within the freezer compartments is controlled by the
thermostat situated on the top of the freezer area. When you fi rst start the
freezer we suggest that you turn the thermostat to a maximum setting until
desired freezer temperatures are achieved. The correct internal temperature
setting can be found by measuring the temperature of the central or middle
portion in the appliance.
THERMOSTAT SETTING
*Optimal Setting = 1.6
Setting = 4
NOTE: Setting 1 being the warmest and 4 the coldest
*NOTE: Mechanical temperature controller has a + or - 0.5 range. The freezer will run a few
degrees colder at high elevations.
ADJUSTMENTS
As the ambient temperature changes with the season, it may be necessary to adjust the thermostat
to achieve the proper internal temperature. If the room/ambient temperature approaches the
appliance's internal operating temperature, the appliance will not function as it should. The
appliance will tend to run colder during these conditions and it may be necessary to turn the
thermostat to a warmer setting (lower number). If the room/ambient temperature exceeds 100˚F
(38˚C), the appliance will not function as it should. The appliance will tend to run warmer and it
may be necessary to turn the thermostat to a colder setting (towards the maximum setting).
OPENING AND CLOSING THE DOOR
The doors are fi tted with uniform sealing strips to prevent warm air and moisture from entering the
freezer compartments. Be sure that the doors and door seals are free from obstructions and form
a complete seal around the rim of the freezer cabinets. Over stuffi ng and/or unlevel installation
of the appliance will prevent a good seal. It might be hard to open the door immediately after the
door is closed. This is due to air contraction in the freezer cabinets. This pressure diff erence will
equalize in a few seconds, making the doors easy to open once again.
