3.1.4.
Check the high-pressure section tightness
Open cylinder valve and pressurize the set. Close cylinder valve. The pressure must never go under 20 bar per minute.
3.1.5.
Check the audible warning signal
•
Open the cylinder valve and pressurize the device
•
Close the cylinder valve
•
Unlock the locking device (pos. 1 in Fig.3) by pressing on the rubber button in the middle of the demand valve cover
•
Close, with the palm of your hand, the demand valve outlet and vent the air off slowly. Watch the gauge and when
reaching a pressure of (70±5) bar, you should hear, strongly releasing, a strong sound vibration that should stop once
there is no more air in the hose. Please note: we recommend releasing the air slowly and waiting a few seconds
depending on the calibration pressures of the alarm.
•
Reinsert the locking device (pos. 1 in Fig.3).
3.2.
DONNING
Adjust the shoulder straps to their maximum length; therefore, lift the special buckles and pull on the ends of the
straps. Put on the self-contained breathing apparatus and pull hard on the ends of the shoulder straps until the
backrest is comfortably leaned against your kidneys. Buckle the belt and pull on the loose ends until achieving the
desired fitting. Insert the loose ends of the shoulder straps under the belt.
Once you put on the device:
•
Put on the mask and make sure it is tightly secured on the face (see the specific instructions of the mask)
•
Open the valve of the cylinder, at least two turns
•
Connect the demand valve to the mask connection: at first breath, the device (pos. 1 fig. 3) unlocks and keeps a
positive pressure under the mask.
Follow the following steps to connect the demand valve to the mask:
-Type A demand valve and mask, standardized EN 148-3 (M45x3) screw connection: screw the male swivel of the
demand valve into the female one of the mask until it stops.
-Type BN demand valve and mask, bayonet connection: insert the male connection of the demand valve into the
coupling of the mask and push until the demand valve 's teeth are hooked into the appropriate tightness edge of the
mask.
Please note: The connection of demand valve to the facemask must be carried out and checked by a second person.
The self-contained breathing device is now ready for use.
3.3.
WHEN USING
From time to time, check the residual pressure of the air reserve with the gauge. When the pressure drops below
(70
±
5) bar, the alarm signal is activated. A loud sound signal will thus appear with every inhalation of air. The signal
will continue until the air reserve has been entirely exhausted.
Please note: when the signal starts, the user shall leave the contaminated area. In case of emergency (greater physical
effort or increased breathing resistance), you can briefly and repeatedly act on the rubber button of the demand valve
to receive air directly into the mask.
3.4.
AFTER USE
•
Close the cylinder valve
•
Disconnect the demand valve from the mask, let the air contained therein out and then press on the button of the
demand valve (pos. 1 in Fig.3):
- Type A demand valve and mask: unscrew the swivel of the demand valve
- Type B and BN demand valve and mask: simultaneously press on the lock buttons and disconnect the demand valve from
the mask
•
Unfasten the waist belt
•
Remove the mask
•
Place the device on the ground without dropping it.
