opaque, discoloured, etc.) it should be replaced as indicated in paragraph 5.3.2. Also check that the
valve seat be perfectly clean.
7.2 Pneumatic tightness test
To carry out this test, you should use the special accessories and apparatus for mask control, supplied
on the request by SPASCIANI S.p.A. (photo 7).
Fit the mask onto the inflatable head and inflate it until the mask adheres without wrinkling, gently pull
the headharness straps. (For further details, see the instructions for the mask testing apparatus).
Dampen with water the contact area between the membrane and the seat of the valve. Create a de-
pression of 10 mbar inside the mask. The depression should not decrease by more than 1 mbar in a
minute. Should the leak be too much, partially deflate the head and dampen with water the contact area
between the bladder and the mask; finally re-inflate the head. If the pressure still decreases, check that
the valve be clean and repeat the test. (For further details, see the instructions for. the mask testing
apparatus).
7.3 Positive Pressure test only for TR 2002 A - BN CL2 and TR 2002 A- BN- S (CL3)
Inject an air flow of some 10 l/min into the mask and verify that the pressure inside the cavity be >= 4.2 mbar.

STORING, DISINFECTING, CLEANING
The rubbers used for the TR 2002 masks have excellent age resistant characteristics and there is therefore
no need to take special precautions for preserving the masks. However it is advisable to keep new face-
pieces in their original packing in a ventilated store-room, away from possible heat sources. Storage should
preferably be between -20 and +50 °C. To keep masks ready for use, it is advisable to keep them in closed
cabinets protected from dust, light and chemical agents' vapours, and far away from heat sources.
After use, masks should be cleaned with a soft cloth to remove sweat and condensation. If they are particu-
larly dirty, they can be cleaned in a household dishwasher, at a max temperature of 40°C, using a normal
detergent. To disinfect facepieces, use special disinfecting towel provided on request (P/N 16009).
The facepieces should be dismantled for both washing and disinfecting. Special care should be taken when
cleaning the exhalation valve.
