Sundstrom SR 500 Gebrauchsanleitung Seite 36

• The particle filter must always be used - either sepa-
rately or in combination with a gas filter.
Particle filter P3 R (PAPR-P3)
Sundström markets only particle filters of the highest
class P3 R (PAPR-P3). Two models are available for fan
SR 500, i.e. SR 510 and SR 710. The filters provide pro-
tection against all types of particles, both solid and li-
quid. The SR 510 can be used separately or combined
with a gas filter. The SR 710 cannot be combined with a
gas filter. The particle filters can be used with the same
pre-filter holder as the one used with the Sundström
half- and full face masks. In these cases, the standard
pre-filter holder of the fan is excluded. See 2. Parts list.
Gas filters A, B, E, K, Hg
A protects against organic gases and vapours, e.g. sol-
vents, with a boiling point of more than +65 °C.
B protects against inorganic gases and vapours, e.g.
chlorine, hydrogen sulphide and hydrogen cyanide.
E protects against acidic gases and vapours, such as
sulphur dioxide and hydrogen fluoride.
K protects against ammonia and certain amines, e.g.
ethylene diamine.
Hg provides protection against mercury vapour. War-
ning! Maximum use time 50 hours.
The gas filters must always be combined with particle
filters P3 R (PAPR-P3). Press the filters together so that
the arrows on the particle filter point towards the gas fil-
ter. Fig. 21.
Combined filter SR 599, A1BE2K1-Hg-P3 R,
(PAPR-A1BE2K1-Hg-P3)
Protects against ABEK-P3 R (PAPR-ABEK-P3) pollu-
tions as described above and in addition against Hg,
mercury vapour. When used to protect against mercury
vapour the period of use is limited to 50 hours.
Pre-filter
The pre-filter protects the main filter against excessively
fast clogging. Fit in the pre-filter holder. The pre-filter hol-
ders protects also the main filters against handling
damage.
Note! The pre-filter can serve only as a pre-filter. It can
never replace the particle filter.
3.2 Assembly
a) Battery
On delivery, the battery fitted in the fan unit is provided
with protective tape over the terminals. Remove the bat-
tery and remove the tape.
• Remove and charge the battery. Fig. 5, 6, 7, 8.
The charger carries out charging automatically in three
stages.

3. Green LED.
• When charging has been completed, pull the plug
out of the socket before separating the battery from
the charger.
• 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.

Warning!
• Always recharge the battery before it has become ful-
ly discharged.
• The charger may be used only for charging the batte-
ries for the SR 500.
• The battery may be charged only with a genuine
Sundström charger.
• The charger is designed only for use indoors.
• The charger must not be covered while it is in use.
• The charger must be protected against moisture.
• Never short circuit the battery.
• Never try to dismantle the battery.
• Never expose the battery to an open flame. There is
risk of explosion/fire.
b) Belt
• Assemble the belt. Fig. 10, 11, 12.
Note! Study the illustrations carefully to ensure that the
belt will not end up upside down or back to front.
c) Breathing hose
Read carefully the user instructions accompanying the
head top.
Full face mask SR 200:
• Assemble the hose between full face mask SR 200
and fan unit SR 500. Fig. 13, 14, 15.
• Check that the hose is firmly secured.
Half mask SR 900:
• Assemble the hose between half mask SR 900 and
fan unit SR 500. Fig. 16, 17.
• Check that the hose is firmly secured.
d) Particle filters/combined filters
Two filters or combined filters of the same type and class
must always be used at the same time.
1. Particle filter SR 510
• Check that the gaskets in the filter mounting of the fan
unit are in place and are in good condition. Fig. 18.
• Snap the particle filter onto the filter adapter. Do not
press onto the centre of the filter - it might damage
the filter paper. Fig. 19.
• Screw the adapter into the filter mounting so far that
the adapter will be in contact with the gasket. Then
turn it about 1/8 turn further in order to ensure a good
seal. Fig. 20.
• Fit one pre-filter into the pre-filter holder. Fig. 21.
• Press the pre-filter holder onto the particle filter.
Fig. 22.
2. Particle filter SR 710
• Check that the gaskets in the filter mounting of the fan
unit are in place and are in good condition. Fig. 18.
• Screw the filter into the filter mounting so far that the
adapter will be in contact with the gasket. Then turn it
about 1/8 of a turn further in order to ensure a good
seal. Fig. 20.
• Fit one pre-filter into the pre-filter holder. Fig. 21.
• Press the pre-filter holder onto the particle filter.
Fig. 22.
3. Combined filters
• Check that the gaskets in the filter mounting of the fan
unit are in place and are in good condition. Fig. 18.
• Snap the particle filter onto the gas filter. The arrows
on the particle filter must point towards the gas filter.
