General inspection

• Inspect the integrity of the dust separator, in particular the steel clamping
rings holding together the housing/inlet/cone-modules.
• Check the integrity of the frame and all attachments. Tighten bolts if
necessary.
• Make sure the inside of the FlexFilter and the connection pipes are free
from deposits. Build up of deposits inside the piping system may cause
discharge of static electricity.
• On Twin models, check the inlet pipe for wear. Replace the inlet pipe if
the inner coating is worn out.
• Make sure the outside of the FlexFilter EX, and particularly the solenoids,
sensors and connection box, are free from dust layers.
• Clean the area around the FlexFilter EX and all areas where the collected
material is stored to ensure that there are no dust deposits.
• Ensure that no combustible material is placed in the risk area.
• Check that all signs/markings regarding safe operation are in place and
that the personnel know about them.

Main filter change

The filter bags should normally be replaced after 6000 hours of operation or
when damaged. The filter bags should also be replaced if the filter function
is insufficient. The HV Control Panel EX is fitted with a service hour meter
for recording service hours. Replacement of filters should be registered in
the Service protocol. Individual replacement of filter bags is possible but
replacing the whole filter package, including filter panel and locking rings, is
recommended as it is quicker and causes less spreading of dust.
