…prepare the battery
New batteries must be charged before they are
used for the first time. On delivery, the battery
fitted in the fan unit is provided with protective
tape over the terminals. Remove the battery and
remove the tape.
Check that the gasket which is situated around
the contact plate opening underneath the
battery is intact.
Connect the battery to the battery charger.
Connect the charger plug to a wall socket.
N.B.! Main voltage 100-240 V
The charger carries out charging in four stages.
1. Yellow LED. Battery analysis and
initiation.
2. Orange LED. The battery is being charged
at maximum charging current.
3. Green –Yellow Intermittent flashing
LED. Top of charging mode.
4. Green LED. Charging completed.

…know the filters
FROM LEFT TO RIGHT:
Particle filter SR 710 P3 R
Particle filter SR 510 P3 R
Gasfilter SR 518 A2
Gasfilter SR 515 ABE1
Gasfilter SR 597 A1BE2K1
Combined filter SR 599 A1BE2K1-Hg-P3
The choice of filters/combined filters depends on
factors such as the type and concentration of
pollutant. The fan unit may be used with only
particle filters SR 510 / SR 710 or with a
combination of particle filters and gas filters or
with a combination filter SR 599. SR 710 is only a
particle filter and can´t be combined with a gas
filter.
The filters used must be of the same type, i.e.
two SR 510 P3 or two SR 518 A2/SR 510 P3, etc.
When filters are changed, both filters/combined
filters must be changed at the same time.
The particle filter must always be used –either
separately or in combination with gas filter.
The gas filters must always be combined with
particle filters P3 R. Press the filters together so
that the arrows on the particle filter point
towards gas filter.
A click confirms that the filters are fully together.
This now works as a combined filter.

Remove the tape and charge the battery.
Push the battery back into the battery
compartment. Check that the battery has been
pushed in as far as it will go and that its lock is
operative.
…assemble the waist belt

…operate the fan unit
Start the fan by pressing the control button.
After the button has been pressed, a
programmed test will be run on the fan unit,
during which the symbols on the display will light
up and the sound signal will sound twice.
After the internal test, all symbols will be
extinguished except the small green fan symbol.
This indicates normal operating status with a
flow of at least 175 l/min.
If the button is pressed again, boosted operating
status will be activated, with a flow of at least
225 l/min. This is indicated by the larger green
fan symbol lighting up.
To revert to normal operation, press the control
button once again.
