The person who is responsible for cleaning and
maintenance of the equipment must have suitable
training and be well acquainted with work of this type.
Routine use and replacement of components
Change the particle filters at the latest when they are
clogged. The fan senses when this has occurred and
provides a warning as described in 1.2 under the
heading Warning system/alarm signals. The gas
cartridges should preferably be changed in accordance
with a predetermined schedule. If no measurements
are made on site, the gas cartridges should be
changed once a week or more frequently if the
pollutants can be smelt or tasted in the head top.
Bear in mind that both filters/combined filter/cartridge
must be changed at the same time and must be of the
same type and class. Proceed as follows:
• Switch off the fan unit.
• Unscrew the filter/combined filter.
• Release the filter holder. Fig. 24.
• Change the pre-filter in its holder. Clean as
necessary.
• To release the particulate filter SR 510 from the
adapter, proceed as follows:
• Grip the filter with one hand.
• Place the thumb of the other hand on the underside
of the adapter at the semicircular gap. Fig. 25.
• Then press out the filter. Fig. 26.
To change the gaskets
The gaskets in the filter mountings of the fan unit
prevent polluted air being drawn into the fan unit. They
must be changed once a year or more frequently if
wear or ageing is detected. Proceed as follows:
• Switch off the fan unit.
• Screw out the filters.
• The gasket has a groove all round and is fitted on a
flange below the threads in the filter mounting.
Fig. 28.
• Remove the old gasket.
Fit the new gasket onto the flange. Check that the
gasket is in place all round.
WARNING: Do not clean respirator with solvents.
Cleaning with solvents may degrade some
respirator components and reduce respirator
effectiveness. Inspect all respirator components
before each use to ensure proper operating
conditions. Failure to do so may result in sickness
or death.
WARNING: Always use genuine Sundström parts.
Do not modify the equipment. The use of
non-genuine parts or modification of the
equipment may reduce the protective function and
put at risk the approvals received by the product.

7. Disposal of Fan Unit, Battery,
Filters
The battery contains no mercury, cadmium or lead, and
is therefore not regarded as environmentally harmful
waste.
The fan unit contains a circuit board with electronic
components, a small proportion of which comprise
toxic substances. For proper handling, collection and
recycling, fans should be handed into a recycling
centre, where they are accepted free of charge. You
may hand in your products as an alternative to the sales
outlet if a new equivalent product is bought.
If you handle the disposal correctly, valuable resources
will be saved and possibly negative effects on human
health will be prevented.
Contact the local authorities for information on the
location of your nearest recycling centre.
