12
Warning!
Use requisite personal protection equipment when performing service
work on the filter unit. Lifts or the like must be used when carrying out service work
above the ground.
12.2 Instructions for Replacing Filter Cassettes
1. Read the electronic manometer A•monitor (or the analogue manometers) and note
down the pressure drop over the different filter stages when the filter unit is in operation.
The filter cassettes whose LEDs light in yellow or red (or whose analogue manometers
have reached the yellow or orange zone) have to be replaced.
2. Turn off the fan and disconnect the filter unit from electricity.
3. Open the service door.
4. Loosen the cassettes by turning the retainer arms as shown on pict. A.
5.
Remove the filter cassettes you want to replace according to
pict. B. When replacing
filter 1, check to see that there is no dirt on the bottom of the filter unit.
6.
Check that the sealing strip on top of the filter cassette is not damaged before you
push in the new filter cassette. (pict. C).
7. Secure the filter cassette (pict. D) and
close the service door.
8. Start the fan and check the pressure drop.
Note!
If the supply air has a high content of chips or shavings, inspect and clean the drain
opening upstream of the return oil tank/pump more often to prevent it from becoming clog-
ged.
