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) bars, 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.
the audible warning is activated with every inhalation. This lasts until the complete exhaustion of the air supply. 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 (pos. 1
•
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 and loosen the shoulder straps by lifting the buckle with your thumb.

4. MAINTENANCE
SPASCIANI S.p.A. will not be liable for damages whenever the maintenance and repair operations were not carried out
within the establishments of its companies or by authorized third parties.
4.1. Cleaning and disinfection
Dirty parts must be cleaned after each use. Clean with warm and soapy water. Rinse with running water. Remove dust
build-ups with a damp cloth or anti-static product. Never use dry cloths and never rub any part of the PPE with wool
or non-antistatic cloths.
Please note: Follow the concentration instructions when using chemical products to disinfect the device. Avoid using
organic solvents that can damage the rubber and plastic parts
4.1.1. Mask
The mask must be cleaned after use, disinfected if the operator changes or in the event of being polluted. The
operations to carry out in this phase are described in detail in the mask user manual. Never use dry cloths to clean the
visor, since the mask could possibly electrostatically charge and become an ignition source in potentially explosive
atmospheres.
4.1.2. Demand valve
To clean the demand valve is generally sufficient to rinse it with warm and soapy water an accurately clean it by using
a soft cloth, leaving it dry naturally. Never use dry cloths to clean the demand valve, since the plastic components
could possibly electrostatically charge and make the demand valve an ignition source in potentially explosive
atmospheres (see par. 8 for ATEX devices).
If the demand valve has been deeply contaminated, proceed disassembling the device in its main components. This
operation, that can be performed by hands without using any tool, implies the handling of the functional components
of the demand valve so it shall be executed by specialized personnel authorized by SPASCIANI S.p.A. Please contact
Spasciani customer service for any information.
