• Disconnect the demand valve from the mask, let the air contained therein out and then press on the button (pos. 1 Fig.5):
- Type A demand valve and mask: unscrew the swivel of the demand valve
- Type B/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
• Remove the mask
• Place the device on the ground without dropping it.
NB: Never store the apparatus with the circuits under pressure.
4. MAINTENANCE
4.1. Cleaning and Disinfection
After each use, it is necessary to clean the soiled parts of the entire device and, if needed, disinfect them.
Always remove the cylinder after depressurizing the apparatus.
To remove dust accumulation, clean with a damp cloth and/or antistatic products. Never use dry cloths and never rub any part of
the PPE with wool cloths or materials that are not antistatic, as they could become electrostatically charged and pose an ignition
risk in potentially explosive atmospheres (see section 8 for ATEX devices).
Cleaning can be performed with lukewarm running water (water temperature should not exceed 50°C) and mild soap (neutral pH
soap) without waxes or fatty substances. Immerse the components that require cleaning in the solution and scrub them with a
soft brush. Rinse with clean water, drain excess water, and allow to air dry thoroughly.
If disinfection is required, it is recommended to use a solution of sodium hypochlorite-based disinfectants (1% solution) or
chlorhexidine-based disinfectants (0.5% solution); in any case, always follow the concentration instructions provided on the
product used. Rinse with clean water, drain excess water, and allow to air dry thoroughly. Avoid using organic solvents, which can
damage rubber and plastic parts, gasoline, or abrasive cleaning products.
Dedicated washing machines/dishwashers with specific programs for individual components may be used. For more information
on washing equipment, contact SPASCIANI customer service.
Particular attention should be given to the cleaning/disinfection of the following components:
- 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.
- 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.
4.2 Cylinders
Follow the existing laws and regulations of the countries where the types of cylinders are used to fill and retest them. When filling
the cylinder, you can exceed the maximum operating pressure by about 10% since, at room temperature, the pressure stabilizes
at the nominal value. When filling, make sure:
• the air complies with the EN 12021:2014 standard.
• the cylinder was checked within the time limits established; this can be done by checking the date of the last retesting on the label.
The valve of the cylinder must be kept closed during transport to prevent humidity from penetrating and condensing.
During transport and storage, the cylinders must be protected from shock.
Do not grasp the valve to transport the cylinders.
