8. State of the regeneration air filter – if this is yellow, the filter should be replaced soon. If this is
red, the service interval has been exceeded. A mechanical pressure switch triggers a warning
(yellow alarm) if the set point is reached. The set point can be manually adjusted at the pressure
switches inside the dehumidifier.
9. State of the process air filter – if this is yellow, the filter should be replaced soon. If this is red,
the service interval has been exceeded. A mechanical pressure switch triggers a warning (yellow
alarm) if the set point is reached. The set point can be manually adjusted at the pressure switches
inside the dehumidifier.
The pressure switch for process air filter is set to 160 Pa and the pressure switch for regeneration air
filter is set to 180 Pa, by default. The setting on the pressure switches must not exceed 200 Pa. Be
aware that the available external pressure (or flow) will decrease as the filters get dirtier. Also note that
higher air flows will reduce the expected lifetime of filters.

Red = alarm = there is a fault or malfunction somewhere (the dehumidifier stops immediately).
Note that if you attempt to change values, you will be asked to enter an operator code (1234).
