Refrigerator Control

Running a Manual Defrost Cycle

This unit is pre-programmed to run automatic defrost cycles at preset intervals. However, if you

would like to run a manual defrost cycle at any time, please follow the steps below:

Refrigerators: Press the defrost button (snowflake symbol and down arrow) for approximately 3

seconds. Repeat to stop the defrost cycle.

Defrost System

Refrigerator coils are kept below the freezing point (32 degrees Fahrenheit). During compressor

down-time, 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. Freezer coils are defrosted

electrically. Automatic defrost timers automatically initiate at pre-set intervals and for a

pre-determined duration.

• If a drainage pipe is available, lower the condensation drainage pipe and connect to a drain or

condensate pump. Verify the pipe is unobstructed and it is lower than the water receiver indicated

by the line on the sticker.

• If no drain is available, the condensation drainage pipe can be hung up. The excess water will be

evaporated with the condensate evaporator pan. Note that the use of this option will increase the

energy consumption of the unit.

• WARNING: High humidity environments can cause increased amounts of condensation that can

overflow the evaporator pan. Connecting the drainage pipe to a nearby drain is necessary for

environments exceeding 55% relative humidity.
