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.
