Functional description
The fan (1) takes in the air from both sides via the coarse dust filter (2) or the Quattro filter, respectiv
ely. After passing the humidification drum, the purified air is led to the outlet lattice (5) and
distributed in the room.
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 humidification drum (3) starts turning. The vaporizer mat is dipped
into the base tub (4) and takes up water. The air passing through the humidification drum absorbs
the humidity.
The coarse dust filter retains dust particles up to 100 µm. If the Defensor PH27/PH27A 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
PH27) or by the level controlled inlet valve (Defensor PH27A).

5.5 Program operation
The operation of the Defensor PH27/PH27A can be controlled via customisable operating programs.
These programs allow to operate the unit at a preset time with the requested operating mode and
fan step. This greatly facilitates the adaption of the Defensor PH27/PH27A to your particular requirements (e.g. adjusted to the business hours and/or working time).
Every program consists of a starting point (day of the week and hour), a reference humidity value,
the operating mode and the desired fan step. Up to 2 starting points with individual programs
may be set up per day.
In program mode the current program remains active until the following program starts (on the same
or on any other day).
Example diagram:
The program settings and the activation of the program mode takes place in the “Timer level”.
5.5.1 Calling the timer level
Within the user level call the timer level (see chapter 5.4.5). In the timer level:
– you can activate and deactivate the program mode (see chapter 5.5.2)
– you can set the day of the week and the hour (see chapter 5.5.3)
– you can define the individual operating programs with their starting points (see chapter 5.5.4)
Note: If no key is pressed in the timer level for a certain time, the unit automatically returns to
standard operation.

6 Maintenance
6.1 Maintenance intervals
The Defensor PH27/PH27A can only provide full humidification and purification performance if the
unit is regularly cleaned and the wearing parts are replaced. The maintenance intervals mostly depend
on the load of the ambient air, the water quality and the operating time.
Please consider the intervals for cleaning and replacing the individual components in the table below
as approximate values. If the room air is heavily contaminated the filters must be cleaned/replaced
more often. If the water is very hard the parts in contact with water must be cleaned more often.
every 2 weeks
As soon as the message
Warning 6

appears or at least every 6 month
Note: If the silver ionisation electrodes are worn, slime will accumulate in the base tub and on the
rot
ary humidification drum. In this case replace the silver ionisation electrodes.
