5.2 Electrical connection of the unit
•
Connect the filter unit to the mains supply.
(Observe the data on the nameplate!)
•
Connect the ventilator to the mains supply via a motor circuit-breaker or a star-delta connection.
If the motor runs in the wrong direction (reduced suction output) then disconnect the ventilator
from the mains supply (pull out the plug) and change over to two phases at the infeed to the
circuit breaker or the star-delta connection. (please comply with the data given on the
nameplate!)
Warning:
Work on the electrical sections must only be carried out by qualified and authorized personnel.
(Observe the data on the nameplate!)

Explanation of the controls
Pos.1
The main switch switches the filter unit on or off.
Pos.2
The operating hour counter starts to count as soon as the filter unit will be switch on.
Pos.3
The operating status lamp shows if the filter unit will be switch on.
Pos.4
The indicator lamp for flow volume shows whether the suction power is adequate. If it
lights up, the filter inserts must be replaced.
Pos.5
The signal horn shows whether the suction power is adequate. When releasing acoustic
signal, the filter inserts must be replaced.

Maintenance
The accumulation of extracted particles on the filter cartridge will eventually lead to a reduction of
the suction / extraction performance.
The mechanical filter element ensures that more than 99% of the extracted pollutants are retained
in the filter. This also applies to a partially or fully saturated filter. However, the extraction
performance of the filter unit will decrease as the filter elements becomes saturated more and
more.
The pre-filter (Pos.14) must be changed at regular intervals. (Refer to chapter 6.1 ‘Changing of pre-
filter element’)
When the internal resistance of the filter element has increased due to the accumulation of the
separated dust particles and the extraction performance of the filter unit decreases as a whole, the
particle filter (Pos. 15) must be changed. (Refer to chapter 6.2 ‘Changing of particle filter element’)
