Commissioning and Maintenance
The following maintenance steps must be carried out:
• Check filter and filter frame for soiling, corrosion and damage, renew as necessary.
The final pressure differential of the bag filter varies and can be obtained from the relevant
technical data (see filter type plate).
• Replace the filter when the maximum pressure differential is reached.
Replacement of filter medium
• Open the service door/panels with sash fasteners when the system is inactive.
• Open the locking springs at the top and bottom guides or open the quick-release filter
frame.
• Pull out filter frame.
• Renew damaged/contaminated filter.
• Push in filter frame. Make sure the seating is airtight!
• Close the locking springs at the top and bottom guides or close the quick-release filter
frame.
• Bag filters may only be installed in an upright position!
• Close service door/panels with sash fasteners.
Maintenance of activated carbon filter
ELECTRICAL HAZARD AND DANGER FROM ROTATING UNIT PARTS!
In doing so, be sure to observe the safety information on page 24.
The following maintenance steps must be carried out:
• If the activated carbon is saturated (when the planned number of operating hours has
elapsed), replace the filter. In order to monitor the level of saturation in the filter, the
cartridge can be weighed to determine the increase in weight and marked accordingly,
then weighed again after a specific time period.
• Check that filter mounting plates with activated carbon cartridges are firmly seated. In
order not to reduce the service life of the costly activated carbon filter, make sure that
the pre- and fine-filtering stages are intact.
Changing activated carbon filters (cartridges)
• Switch off the system.
The cartridges are secured with special bolts (bayonet fitting).
• Turn the filter cartridges in the direction of the arrow and remove from the frame.
• Also replace the preliminary filter when changing the activated carbon filter.
• Dispose of the filters in accordance with the applicable regional regulations.
