abilities or persons with lacking experience and/or knowledge, unless they are supervised by a person
responsible for their safety or they received instructions on how to operate the unit.
Children must be supervised to make sure that they do not play with unit.
Intended use
The air purifier/air humidifier Defensor PH15/PH15A is intended exclusively for air purification and
air humidification within the specified operating conditions (see chapter 9 “Product specifica-
tions”). Any other type of application without the express written consent of the manufacturer is
considered as not conforming with the intended purpose and may lead to the Defensor PH15/PH15A
becoming dangerous.
Operation of the equipment in the intended manner requires that all the information in these
instructions are observed (in particular the safety instructions).

7
Danger that may arise from the unit
– The Defensor PH15/PH15A is mains powered.
DANGER!
One may get in touch with live parts when the unit is open. Touching live
parts may cause severe injury or danger to life.
Prevention: Before carrying out any work set the Defensor PH15/PH15A out of operation
(switch off the unit, disconnect it from the mains, close water supply) and secure
the unit against inadvertent power-up.
– Poorly maintained humidifiers can endanger your health.
WARNING!
If the Defensor PH15/PH15A is insufficiently maintained harmful germs can
build up in the water and the filters an can affect the ambient air.
Prevention: The Defensor PH15/PH15A has to be cleaned in regular intervals according to
chapter 6 “Maintenance”. The cleaning work has to be carried out correctly and
the evaporator mat as well as the filters have to be replaced after the specified
lifetime.
Handling the mains cable
Handle the mains cable with care: keep it away from sharp edges and do not jam or strain it.
Never remove the mains plug by pulling the mains cable. Make sure your hands are absolutely dry
when pulling the plug out of the socket.
Lay out the mains cable so that it does not become a stumbling trap.
Connect mains cable only to a mains socket with protection earth. Any extension cable used must
be equipped with a protection earth too.
Behaviour in case of danger
If it is suspected that safe operation is no longer possible, then the Defensor PH15/PH15A should
immediately be disconnected from the mains (disconnect mains connector) and secured against
accidental power-up. This can be the case under the following circumstances:
– if the Defensor PH15/PH15A is damaged
– if the Defensor PH15/PH15A is no longer operating correctly
– if connections and/or piping are not sealed
– if the mains cable is damaged
All persons working with the Defensor PH15/PH15A must report any alterations to the unit that may
affect safety to the owner without delay.
Prohibited modifications to the unit
No modifications must be undertaken on the Defensor PH15/PH15A without the express written

Functional description
The radial fan (1) takes in the air from the top via the coarse filter (2). After passing through the
evaporator mat (3) (or the activated carbon evaporator mat) and the coarse dust filter (4) (or the
Quattro filter) the air is blown out via the outlet lattice on both sides of the unit.
The unit continuously measures the air humidity in the room with the integrated humidity sensor
and compares it with the set reference humidity value. If the actual value (e.g. 40 %rh) is below the
reference value (e.g. 45 %rh) the centrifuge (5) starts and projects fine drops towards the evaporator
mat. The air passing through the evaporator mat absorbs the humidity.
The coarse dust filter retains dust particles up to 100 µm. If the Defensor PH15/PH15A is equipped
with a Quattro filter it can retain dust particles up to 0.1 µm. In addition the activated charcoal layer
in the Quattro filter removes unpleasant odour.
The water level in the base tub is monitored by the level regulating valve in the water tank (Defensor
PH15) or by the level controlled inlet valve (Defensor PH15A).

Operating modes
The Defensor PH15/PH15A can be operated in the following operating modes:
– Operation as air humidifier
In the humidifier mode the ventilator and the centrifuge 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 with humidification
In this operating mode the fan is running continuously. The centrifuge is only switched on if the
actual humidity value is below the set reference value.
– Operation as air purifier without humidification
In this operating mode the fan is running continuously. The centrifuge remains switched off.

Notes on setting: The optimum reference value depends on various factors. For apartments we
recommend a value of 40 – 45 %rH.
Note: After initial commissioning or replacement of the vaporizer mat the humidification perform-
ance of the Defensor PH15/PH15A will be slightly reduced because the evaporator mat takes a
few days to become fully saturated with water. Maximum performance is available after one week,
approximately.
Furthermore, the humidification performance depends on the ambient temperature.
