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:
1. Press the defrost button (snowflake symbol and down arrow) for approximately 3 seconds.
2. Repeat to stop the defrost cycle.
Defrost System:
Refrigerator coils are kept below the freezing point (32 degrees Fahrenheit). 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 automatically initiate at pre-set intervals and for a
pre-determined duration.
•
If drainage pipe is available, lower the condensation drainage pipe and connect to a drain or condensa-
tion pump. Verify the pipe is unobstructed and it is lower than the water reciever 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 evapo-
rated with the condensate evaporator pan. Note that the use of this option will increase the energy
consumption of the unit.
•
WARNING: High humidity enviroments can cause increased amounts of condensation that can over-
flow the evaporator pan. Connecting the drainage pipe to a nearby drain is necessary for enviroments
exceeding 55% relative humidity.
