The Whitewing Defender uses a refrigeration system similar to an air conditioner’s to remove heat and moisture from incoming air and add heat to the air that is discharged.

Hot, high-pressure refrigerant gas is routed from the compressor to the condenser coil. The refrigerant is cooled and condensed by giving up its heat to the air that is about to be discharged from the unit. The refrigerant liquid then passes through a filter/ drier and capillary tubing, which cause the refrigerant pressure and temperature to drop. It next enters the evaporator coil where it absorbs heat from the incoming air and evaporates.

The evaporator operates in a flooded condition, which means that all the evaporator tubes contain liquid refrigerant during normal operation. A flooded evaporator should maintain constant pressure and temperature across the entire coil, from inlet ton outlet.

The mixture of gas and liquid refrigerant enter the accumulator after leaving the evaporator coil. The accumulator prevents any liquid refrigerant from reaching the compressor. The compressor evacuates the cool refrigerant gas from the accumulator and compresses it to a high pressure and temperature gas to repeat the process.

The Whitewing Defender basement dehumidifier is equipped with two air filters. An aluminum/ foam pre-filter followed by a standard MERV-11 plus Carbon 65% efficient pleated fabric filter. These should be checked every six months. Operating the unit with dirty filters will reduce dehumidifier capacity and efficiency and may cause the compressor to cycle off and on unnecessarily.

If dirty, the aluminum/ foam pre-filter can be vacuumed or carefully hand washed with warm water and mild detergent then rinsed and allowed to thoroughly dry. The pleated fabric filter can generally be vacuumed clean several times before needing replacement. Replacement filters can be ordered from this page by clicking on the Filters & Accessories tabs. DO NOT operate the unit without the filters or with a less effective filter. The heat exchange coils inside the unit could become clogged and require dis-assembly to clean.
