5.7 Defrosting by 4-way valve(DRY 300/500)– on demand
Defrosting with hot gas allows the dehumidifier to work efficiently at air temperatures as low as 5 ° C. It is
designed for demanding operations at low air temperatures. Although the efficiency of the device in terms of
extraction rate versus energy consumption at 5 ° C ambient air is low, the dehumidifier will continue to operate
normally. If the dehumidifier is equipped with a hot gas defrost accessory, then the gas circuit is equipped with
a 4-way valve. When the temperature on the evaporator drops below zero, the system starts counting for 30
minutes. After this time, the evaporator temperature is checked again and if the current temperature is still
below zero, the compressor and fan are switched off. The dehumidification then stops. The gas circuit is turned
and after 3 minutes the compressor is started. The system now defrosts the appliance for 3 minutes. For
another 3 minutes, if the thaw is complete, the unit will return to normal operations. At extremely low
temperatures and sufficiently humid air, it is normal for 2 or 3 defrost cycles to take place in succession.
5.8 Air filter – len na vyžiadanie
Your dehumidifier can be equipped with an air filter on request. The air filter traps dust and other mechanical
particles and prevents them from entering the fins of aluminum heat exchangers. Although the air filter
contributes to the cleanliness of the dehumidifier, it does not have the function of an antibacterial HEPA filter.
For DRY300 / 400/500 WAVE models designed for wall mounting, it is a fiberglass mesh. In the case of the
"behind the wall" design, it is a filter of class G3 or G4.
The operation of your dehumidifier is highly dependent on the continuous supply of air from the environment.
It is therefore important to keep the air filter clean. Please read the simple steps below to clean the filter. If the
filter is clogged with dirt, it creates a barrier to air supply. The manufacturer recommends cleaning at least
once a month. The manufacturer, distributor and dealer are not responsible for damage or malfunction of the
device resulting from insufficient cleaning of the air filter.
