Product- and functional description
Introduction: This section will give you a description of the machines and the functions:
Principles of The following describes the air flow
operation: through the dehumidifier:
The air flow through the
dehumidifier.
A
fan draws in humid air through a
filter to the dehumidifier.
The air is cooled down and humidity/water
drops are led down to the water
tank.
The air is re-heated by e.g. the operation
of the dehumidifier (approx. increase in
temperature is +5°C/41°F).
Due to the repeated air circulation through the dehumidifiers, the air humidity is
continuously reduced whereby achieving rapid, but gentle drying.
The dehumidifier will operate continuously unless a hygrostat (accessories - page 11)
is connected.

Water Tank: Water is collected in the water tank. Alternatively, you can also setup the dehumidifier for
permanent drainage with the adapter for hose connection (accessories).
When the water tank is full, the dehumidifiers shut off automatically.
Emptying of the water tank, see manual, page 7.
Operation of the unit is not possible once the water tank is removed.
