7.1. Reset to maintenance state
●
Switch off the unit. Unplug the mains plug. Secure the unit against unauthorized restarting
during maintenance.
●
After completion of all maintenance work the unit can be reconnected to the power supply.
7.2. Replacing the microfilter mats
The microfilter mats must be changed after a certain number of operating hours. The time depends on
the amount of accumulated dust, and therefore cannot be determined beforehand.
CAUTION
Whirling up dust is possible.
The microfilter mat is a disposable filter element. Do not try to clean the filter element.
●
Release the protective grilles on both sides (suction grille and exhaust grille, see chapter 2.1).
To do this, release the 4 screw connections of both grilles.
●
Replace the microfilter mats with new ones.
Only use TEKA spare filters. Otherwise the proper functioning of the unit is
not guaranteed.
●
Screw on the protective grilles again.
