Replacing filter cartridges or emptying dustbins
• Shut off the compressed air feed and empty the pressure
tank(s) of air by opening the drain valve(s) on the back

internal leakage and a reduced filter efficiency. In
combination with SHIELD fire safety solutions it
can lead to a false fire alarm.

necessary caution, may cause serious personal
injury.
Use breathing protection, if not carried out with
the necessary caution, may cause serious personal

To change the filters with minimum release of dust into the
atmosphere, first change the upper filter cartridges and then
the lower ones.
Remove the filter cartridges from the MultiDust Bank
carefully, taking care not to jog them.
Wear the disposable gloves supplied with the replacement
filters, and place the used filter cartridges in the plastic sack
supplied.
• Unscrew the knob.
• Take off the cover lid and unscrew the nut, metal washer
and rubber ring that hold the filter cartridge.
• Take out the filter cartridge.
• Place the used filter cartridge in the packing of the
replacement filter and seal securely.
• Replace in reverse order. (The filter cartridge can only be
mounted in one way).
• Check that the cover lid presses against the filter housing
wall when a new filter cartridge has been fitted.
NOTE: when changing filter cartridges, the start-up routines
must be followed. See start-up procedure in the product
manual.
