Electrical
• Please ensure that the required voltage is being supplied at all times.
• The unit should be plugged into a grounded and properly-sized electrical outlet with appropriate
over-current projection. NEVER USE AN ADAPTER PLUG! Please refer to the electrical requirements
on the unit’s nameplate.
• This unit should have its own dedicated outlet.
• Do not use extention cords.
• Ensure the unit is not resting on or against the electrical cord.
• If the unit is not in use for a long period of time, please unplug the unit from the outlet.
• To avoid shock and fire hazards, do not plug in or unplug the unit with wet hands.
• After unplugging the unit, wait at least 10 minutes before plugging it back in. Failure to do so could
cause damage to the compressor.
Adjusting the Temperature
Controller #1
Your new freezer is already factory-set to run at optimum
temperature for food safety and should require no adjustments.
Freezers are set to cycle between a minimum temperature of -5 degrees
Fahrenheit and a maximum temperature of 2 degrees Fahrenheit.
Adjusting the temperature changes the minimum temperature your unit
will run at. Your unit will not constantly at this setting. To change it, follow
these instructions.
Digital Control Units
• Hold “SET” for 1 sec. The display will flash the current minimum temperature.
• Use the arrow buttons to adjust the minimum temperature you want it to run at.
• Press “SET” again to save your settings.
Always remember to calculate the dierential if you change the minimum temperature setting. The cabinet
temperature will fluctuate up to +7 degrees over your set minimum temperature as the compressor runs and
shuts o. Setting the temperature too high will result in unsafe maximum temperatures and possible health
code violations.
Defrost System
Freezer coils are defrosted electrically. Automatic defrost timers automatically initiate at pre-set intervals and
for a pre-determined duration.
