7. MASK EFFICIENCY CHECKS
The maintenance, disassembly and replacement of the masks components (except those described in paragraph 5)
must only be performed by the Manufacturer or its authorized workshops, or by the user if specifically trained by
SPASCIANI, who periodically organizes training courses for this purpose.
At each re‐assembly of the mask, after cleaning and before use after a period of long inactivity, the mask efficiency
must be checked; to perform these checks, ARAC or ARAC Mini devices (Spasciani products, Fig.7), can be used.
For all information regarding maintenance courses, spare parts and control equipment, please contact the Spasciani
sales office.
8. 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
General Visual inspection (Connector, visor, inhalation valve,
headharness, speech device and inner half mask)
