SPECIAL FEATURES
DEFROST OPERATION
If the ambient temperature of the room in which the dehumidifier is
conditioning, falls below 15ºC ice will form on the evaporator coil as the air
passes over it. Over a period of time this build up of ice will affect the
efficiency of the dehumidifier on its ability to maintain the required set
conditions within the room.
The Free Star is therefore fitted with a defrost control device. This defrost
control device is equipped with a thermistor which will only engage the defrost
cycle when needed. During the defrost cycle the high pressure hot gas from
the compressor is diverted into the evaporator coil where it melts the ice
which has formed on the evaporator coil.
CONTROL PANEL LIGHTS
The On/Off Switch illuminates when the unit is turned on to give a visual
indication that the unit has power.
The unit also has 2 lights on the control panel which are green and amber,
when the green light is illuminated this indicates that the unit is going through
its drying process. When the amber light is illuminated this indicates that the
unit is going through the defrost cycle.
