4.7 Information regarding the change of filter
The frequency of the change of filter depends on the degree of pollution of the filter. If the
sealing up of the filter increases (contamination of the filter), the air capacity decreases.
For the control of the filter during the operation, the device is equipped with a manometer
(for D 60 E a signal light).
Important: Use only approved, faultless filter!
From the following chart you can take for the change of the filter, the indications of
values for the filter as-new condition and the indications of the recommended change of
the filter. If the indication reaches the value for the recommended change of filter do
please first change the preliminary and intermediate filter. If the indication falls at 100
Pascal (for D 60 at 50 Pascal) or more, the device can be operated further. If the value
falls at lesser than 100 Pascal (for D 60 at 50 Pascal), you have to change the Hepa filter
