7.5 Changing the filter cartridges
If the suction capacity is no longer sufficient for your purposes, you must check for causes of error
(see chapter 10
„Diagnostics and troubleshooting“
).
Otherwise it is possible that the filter cartridges are saturated so that a replacement of the filter car-
tridges is necessary. On the basis of experience the filter unit is preset in a way that for this case
the horn (pos.21) will sound and on the Display control (pos.13) appears a message (“Filteralarm”).
If, despite automatic cleaning of the filter cartridge the pressure continues not to fall short of the
alarm value, the filter cartridge needs to be replaced.
The filter cartridge must be cleaned before starting the changing.
For this you have to proceed a manual cleaning via the system control (see separate manual) three
times. The filter unit must be switched off beforehand but without disconnecting the unit from the
power supply. After that the filter unit must be disconnected from the power supply and secured
against restart. Please wait for 5 minutes after the cleaning of the filter cartridge.
•
The replacement of filter cartridges must be carried out by two people.
•
Before changing the filter cartridge ensure a suitable container (e.g. plastic bag ) is ready.
The dirty filter cartridges must be packed in an appropriate manner (e.g.
plastic bags). Plastic bags are optionally available (see spare parts list)! We recom-
mend promptly stocking up on plastic bags.
•
Open the service door of the filter cartridges by opening the door handles. To do this, the
door handle, which is equipped with a lock, must be unlocked using a double-bit key.
•
Remove the set screw (pos. A) of the cartridge holder (pos. B) and place the disposal bag
over the cartridge holder and the filter cartridge (pos. C).
