The impurities
are
separated (by
the
pneumatic impulses) from
the
filter surface. Subsequently
they fall through the discharge hopper chamber into the waste container. The waste container
must be emptied systematically.
Periodically,

regeneration ought
to be
dewatered by opening
the discharge valve.
The condensate water (dripping) must be discharged
from the system. Subsequently, close the
dewatering valve at the moment when the discharging air is clean and dry .
The construction of the
extraction fan and motor guarantees the work of the unit without the rou-
tine everyday technical maintenance. In case when defective function of the device is noticed,
submit the device to technical revision (see Section 8).
Any repair activity and technical revisions are admissible to be carried
out exclusively after the device is disconnected from the power supply system.

9. Maintenance
9.1 Cartridge filters
Upon every emptying of the waste container (under the hopper), examine visually the state of
the cartridge filters. First disconnect the power supply.
Through the front revision door, check the mounting correctness of
the elements , the state of
the filtration surface, pollution degree, search for failures, etc.
