4.5 Spare parts

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.
4.5.1 To change the particle filters/
combined filters
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 filters
should preferably be changed in accordance with a
predetermined schedule. If no measurements are
made on site, the gas filters 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 filters 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 particle filter SR 510 from the
adapter, proceed as follows:
o Grip the filter with one hand.
o Place the thumb of the other hand on the
underside of the adapter at the semicircular
gap. Fig. 25.
o Then prise out the filter. Fig. 26.
• To release the particle filter SR 510 from the gas
filter, proceed as follows:
o Grip the gas filter with one hand.
o Insert a coin or some other flat object, e.g. the
filter adapter, in the joint between the particle
and gas filters.
o Then prise out the filter. Fig. 27.
Fit new filters/combined filters. See 2.5 d).
4.5.2 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.
