Electrical

• 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 protection. Refer to the electrical requirements on the unit’s nameplate.
• The unit should have its own dedicated outlet.
• DO NOT use extension 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, unplug 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.

Temperature Controls

Adjusting the Temperature

• Your new refrigerator is already factory-set to run at optimum temperatures for food safety and should require no adjustments.
• Refrigerators are set to cycle between a minimum temperature of 33°F and a maximum temperature of 40°F.
• Adjusting the temperature changes the minimum temperature at which your unit will run. Your unit will not run constantly at this setting. To change it, follow these instructions:

Digital Control Units

1. Hold “SET” for 1 second. The display will flash the current minimum temperature.
2. Use the arrow buttons to adjust the minimum temperature you’d like the unit to run at.
3. Press “SET” again to save your settings.
   • Always remember to calculate the differential if you change the minimum temperature setting. The cabinet temperature will fluctuate up to 7°F over your set minimum temperature as the compressor runs and shuts off. Setting the temperature too high will result in unsafe maximum temperatures and
   possible health code violations.

Operation

Defrost System

Automatic Defrost Cycle

• Refrigerator coils are kept below the freezing point (32°F).
• During compressor downtime, the evaporator fan continues to circulate air through the evaporator coil. This air circulation raises the coil temperature above the freezing point, melting any accumulated frost.
• Run-off water is drained into the evaporator pan and evaporated.
• Automatic defrost timers initiate at pre-set intervals and for a pre-determined duration. Running a Manual Defrost Cycle
• Units are pre-programmed to run automatic defrost cycles at preset intervals. However, if you would like to run a manual defrost cycle at any time, follow the steps below. Only models with digital controls can run a manual defrost cycle. Units with mechanical controls cannot run a manual defrost cycle.
• Controller #1: Press the defrost button (“DEF” and ▼) for approximately 5 seconds. Repeat to stop the defrost cycle.
• Controller #2: Press the defrost button (Snowflake and ▼) for approximately 3 seconds. Repeat to stop the defrost cycle.
