underneath, it can be rapidly discarded (thrown away). Mind, the workers should necessarily wear antistatic
clothes. Additionally, the waste container (while withdrawal, mounting) must be placed on an antistatic pad.
This activity should be carried out, after the fan is switched off and the device disconnected from the power supply
mains. When the waste container is fastened back to the device, mind that the contact surfaces are clean and the
seal is suitable to the edge between the waste container and the hopper chamber.
7.6 Measures of precautions during the maintenance
The filtering unit must be used according to the present Use and Maintenance Manual and according to the
being in force regulations.
Maintenance steps / activities should be executed by authorised workers after the instructions.
In the course of operational use, be careful that no ignition sources (e.g. sparks, cigarette butts, embers) will
get into the device.
During the emptying of the waste container and during any other activity near the filtering unit, it is important
to wear the antistatic clothes. Put the antistatic pad/rug underneath the waste container.
Directly, at the filtering unit, and in the vicinity
– do not use mobile phones and other devices emitting
electromagnetic waves.

MAINTENANCE AND REPAIR
9.1 Cartridge filters
It is necessary to undertake a visual control of the cartridge filters, at any case when the waste container
(underneath the hopper chamber) is emptied of the dust. Examine the state of the mounting elements, the state
of the filtration surface, the degree of pollution, the presence of damages, etc.
– through the inspection door.
Additionally, this revision should be carried out in case when any improper function of the device is noticed.
In case the cartridge filters are damaged or worn out
– replace them for new. The filters should be drawn out,
beginning from the filter closest to the inspection door. Before User draws out the filter, first release the mounting
nuts, turn the filter itself and take it out.
9.2 Fan
Technical revision and maintenance of the fan should be executed according to the instruction of the fan. In case
when faulty function of the fan is noticed, please contact the producer. The fan motor must be submitted to
systematic maintenance, to provide correct function and safety. Follow steps strictly as described in the
instructions of the fan manufacturer. When necessary, replace the fan or motor for new and this can be carried
out exclusively by an authorised personnel.
9.3 Compressed air tank.
The compressed air tank must be submit to technical revision and maintenance, according to the valid regulation
on the pressure devices. Periodically, examine all the connections on the compressed air tank. It is important to
dewater the tank, through the connection (installed in the lower part of the tank).
9.4 Electromagnetic valves
Electromagnetic valves do not require current maintenance. Simply, it is sufficient to check the electrical
connections, the state of grounding and tightness on the pneumatic installation.
