3.7 Replacing the Exhaust Air
Labyrinth
Dust from the suction turbine graphite brushes also
settles on the walls of the exhaust air labyrinth. Over
time, the labyrinth will become discoloured.
Before opening the unit, disconnect it from
the mains power supply by unplugging the
power cord from the wall outlet.
Replacing the exhaust air labyrinth:
• Turn the lock knob 90° anticlockwise (Fig. 25).
• Remove the motor compartment cover.
• Pull the exhaust air labyrinth out towards the back.
•
Install the new exhaust air labyrinth by pushing
it in straight, making sure it is properly seated.
The openings in the exhaust air labyrinth must
face towards the rear (Fig. 30) and the metal
grating downwards.
• Check that the lock knob is in the open position
(vertical).
• Place the motor compartment cover on the motor
compartment. Two guide pins have been provided
on the cover to assist in positioning it correctly.
• Turn the lock knob 90° clockwise (Fig. 31).
Always comply with all local ordinances
governing proper disposal and accident
prevention!
