4. Maintenance and replacing of filters
Except for occasionally readjustment of the joints of the exhaust arm (see instruction manual
of the exhaust arm), the unit is operating maintenance – free. Only the filter insert has to be
changed, when it becomes necessary. The saturation level of the filter ist electrically monitored.
It is indicated by the red monitor light.
Follow these steps to change the filter unit:
• Disconnect the power supply!
• Open the snap-fasteners on the cover of the unit.
• Lift the cover with one hand. Hold the exhaust arm with the other hand.
Open it so far until the exhaust arm touches the ground.
• Change the pre-filter and the filter casette.
• Assemble the filter unit in reverse sequence.
Caution!
Do not attempt to clean the main filter. Shaking it or using compressed
air will destroy the filter! Contaminated particles can reenter the room.
5. Technical data
Because the filter unit can be delivered in different voltages and frequences,
please refer to your unit’s respective type plate.
