7. Operation of the Cooling System & Defrosting
If the unit is operating in low temperatures the evaporator within the chamber may get covered with a layer
of ice. One symptom of too much ice on the evaporator is lower cooling efficiency of the unit, which will
have an adverse effect on performance and overall lifespan. To ensure proper operation of the unit, you
should follow these principles:
1.
In temperatures above +8°C, the chamber air automatically defrosts the ice cover, defrosting is self-
operating.
2.
In temperatures below +8°C, the evaporator may be covered in ice and the unit will be automatically
defrosted.
This occurs by default 3 times a day as a ‘passive’ defrost. i.e. the unit waits a
predetermined length of time before running the compressor again allowing the temperature to rise
slightly higher than normal operation.
3.
If excessive ice levels build up within the chamber, please switch off the unit and manually defrost
by leaving the door ajar for 12 hours. Be sure to wipe up any excess moisture within the chamber
before switching the unit back on.
4.
Always make sure the door has been closed quickly and properly to avoid rapid ice appearing!
