Check the filer section to ensure it is clean and vacuum up any coarse dirt and debris as
necessary, and then wipe up any fine dust using a damp rag. Then check the condition and seal
around all filter elements. During filter replacement, it is necessary to avoid contaminating
other parts of the unit or new filter elements with dust.

Bag and frame filters
Per the class of filtration of the used filters and their replacement interval, it is
necessary to ensure a complete set of replacement filters is kept on-hand and ensure
that their maximum storage period has not been exceeded. We recommend defining a
filter replacement interval based on observations during test operation of the unit. This
interval may depend on local conditions and may be shorter or longer than the regular
maintenance interval. It no case should the maximum allowed terminal pressure loss
for the specific type of filter elements in use, or the 12-month filter replacement
interval, be exceeded. All filters are changed at the same time.
A different differential pressure value may be set manually on the switching manostat for
the given supply / return filter bank. The manostats are located beneath the filters on the side
of the chamber, see the following illustration.
