OPERATING INSTRUCTIONS
Defrost cycles
Refrigerator
There is no need for routine defrosting of the unit as this occurs automatically as follows:
1. Cycle defrost
To keep the temperature stable inside the chamber, the refrigeration compressor is cycled on and off.
During “off” periods any frost which has accumulated on the refrigeration coils is melted by energizing a
small heater. This will not have any discernible effect on the chamber temperature.
2. Forced defrost
When the set temperature is low, ambient humidity is high, or a large amount of damp product is being
stored inside the refrigerator, there is a possibility that cycle defrost may not be enough to remove all of
the frost on the refrigeration coils. In this case, a forced defrost cycle can be initiated.
When the unit is operating under a forced defrost cycle, the current chamber temperature and “dF” is
displayed alternately on the digital temperature display.
Once the forced defrost cycle is complete, normal operation resumes. The chamber temperature rises
to about 10
o
C during the forced defrost cycle.
Freezer
When the frost is built-up on the freezer wall, defrost the freezer by the following procedure as the freezer
has no automatic defrosting function.
1. Temporarily move all the contents of the freezer to another freezer.
2. Turn the freezer switch to “OFF”.
3. When the frost on the wall has been eliminated, remove the water and wipe the inside of the freezer
completely.
4. Turn the freezer switch to “ON”.
5. Once the chamber temperature has resumed normal set-point temperature, place the original contents
back in the freezer.
Note: The freezer does not automatically reset to normal operation.
