7.8.2. Replacing the activated carbon cassette
● Open the service door of the activated carbon 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 activated carbon cassette (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 activated carbon cassette.
Only use TEKA spare filters. Otherwise the proper functioning of the unit is
not guaranteed.
● Push the filter pack back into the filter housing. 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 entire filter pack is pressed
tightly against the above housing.
● Re-establish the two earth connections.
There is a risk of explosion during operation if an earth connection is not
attached.
● Close the service door.
