All work with the fan unit must be done with

A speed control controls the extraction capacity by ad-
justing the speed of the fan (see
The fan is equipped with a thermal contact which re-
leases at too high temperature. The contact reverts
automatically.
6 Maintenance
WARNING! Risk of personal injury
All work with the fan unit must be done with
the plug disconnected.
6.1 When must the filter unit be re-
placed?
The disposable filter is not designed to be cleaned.
The filter´s effective life is directly related to the en-
vironment in which it is used and the particles it is
required to filter away. Normally, however, a filter
should have a life of several months.
The filter unit contains a particle filter and a carbon fil-
ter. A full particle filter is indicated by an inadequate
suction capacity. A full carbon filter is indicated by an
increasing odour.
To ensure the filter unit is replaced regularly, mark the
date the filter unit was brought into use.

6.2 Replacing the filter unit
WARNING! Risk of personal injury
When changing the filter you may come in con-
tact with hazardous substances accumulated
in the filter. Use necessary Personal Protective
Equipment when replacing the filter cartridges.
1
Disconnect the power from the fan.
2
Lift and separate the fan from the top of the filter.
3
Remove the o-ring gasket from the fan discharge
by moving it down and over the flared end.
4
Clean off any dirt or debris that may be present.
5
A new o-ring gasket is included with the replace-
ment filter. Remove the o-ring from the package
and inspect it to ensure there are no tears or other
damage that would hinder the seal.
6
Fit the o-ring gasket over the flared end of the
fan discharge and push the gasket all the way up
against the flange to fully seat. Ensure there are
no twists or gaps once the gasket is installed.
7
With the o-ring gasket installed, insert the fan dis-
charge duct into the new filter. Ensure that the
fan is fully inserted into the filter with the gasket
slightly compressed. A gap between fan flange
and top of the filter of 1.6 mm maximum will be
noticed. If the gap is larger, the fan is not fully in-
stalled and may result in leakage.
8
Prior to returning to service, connect the power
for the fan, turn the fan on and visually inspect the
filter and fan connection for any leaks. If any leak
is found, contact your local distributor for assist-
ance.
9
Seal the used filter with the plastic cover supplied
with the new filter. Put the used filter in a plastic
bag and handle the used filter cartridge according
to relevant regulation for the substance that has
been collected.
