Special Features; Defrost Operation - EIP HGR1500 User Manual

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 effect the
efficiency of the dehumidifier on its ability to maintain the required set
conditions within the room.
The HGR1500 is therefore fitted with a defrost control device.
When the unit is operated in ambient of less than 15° C, a defrost cycle should
occur approximately every hour. The exact time is impossible to predict as the
unit is fitted with a temperature sensitive defrost control.
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.
