Options - Defensor PH28 Operating Instructions Manual

Two silver ionisation electrodes prevent the formation of slime and microorganisms in the base tub
and on the humidification drum. The ionizer electrodes are active as soon as the Defensor PH28/
PH28A is switched on.
Operating modes
The Defensor PH28/PH28A can be operated in the following operating modes:
– Operation as air humidifier
In the humidifier mode the ventilator and the humidification drum are running only, if the actual
humidity value is below the set reference value.
Note: if the actual humidity value remains below the reference value for a prolonged period of
time, the fan must be switched to the next highest level.
– Operation as air purifier (without humidification)
In this operating mode the fan is running continuously. The humidification drum remains switched
off.
– Operation as air purifier/humidifier (Combined mode)
In this operating mode the fan is running continuously. The humidification drum is only switched
on if the actual humidity value is below the set reference value.
