4.4.1 To change/charge the battery
See 2.5
4.4.2 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:
• 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 prise out the filter. Fig. 26.
