7.7. Replacing the particle filter
Replacing the particle filter is necessary when the device control signals the corresponding error. (see
chapter "Description of the control elements").
Whirling up dust is possible.
The particle filter is a disposable filter element. Do not try to clean the filter element.
The particle filter has the function of a police filter. This means that the filter is located behind the
other filter elements according to the air flow direction. The police filter ensures that only clean air
from the filter system flows back into the environment, even if one of the other filter elements is
defective. The filter unit switches off when the police filter is saturated and can not be operated as
long as the error message persists.
● Open the service door of the particle filter housing (see chapter 2.1).
● Release the two earth connections.
● Lower the lifting device (A) by turning the clamping screw (B).
● Carefully pull the entire filter pack, incl. the particle filter (see chapter 2.1) out of the housing.
Before doing so the projecting measuring hose has to be separated from the intermediate
frame.
● Replace the particle filter.
Only use TEKA spare filters. Otherwise the proper functioning of the unit is
not guaranteed.
● Push the filter pack back into the filter housing as far as it will go. Make sure that the filter
elements are inserted in the correct order. Then reconnect the measuring hose at the
intermediate frame.
The seals of the particle filter, the activated carbon cassette and the
intermediate frame must always be on the top.
● Elevate the lifting device by turning the clamping screw so that the upper filter element is
pressed tightly against the above housing.
