4 LEAKAGE AND FUNCTION TEST
Caution!
Prior to and after use, perform a visual inspection of all plastic, rubber and metal parts for damage. If any damaged
parts are found the SCBA must be taken out of service and repaired according to the SPIROMATIC S8 Service Manual.
Repairs are to be made by INTERSPIRO or a holder of an INTERSPIRO Service Certificate.
1. Open the ambient air hatch by pressing down the hatch lever and gently
pushing out the exhalation valve cover.
2. Open the cylinder valve carefully.
3. Turn on the positive pressure by closing the ambient air hatch. A strong
flow of air should be heard.
4. Turn off the positive pressure by opening the hatch.
5. The BAC emits a sound and the BAC and DDU LEDs start to flash yellow
indicating PASS Sensing mode. The digital display activates.
6. Check that the PASS pre-alert and alarm modes are operational as described in the section 6.2 and section 6.3.
WARNING!
Failure to ensure that the PASS is fully operational prior to use may expose the user to serious injury or loss of life.
Although the PASS meets all current NFPA specifications, there is no inherent guarantee against PASS failure. Even the
best PASS cannot compensate for abuse or the lack of a PASS training and maintenance program.
Limitation!
SPIROMATIC S8 that include an integrated PASS are only approved for use as an integrated SCBA/PASS system. If the
PASS is not fully functional then SPIROMATIC S8 must be removed from service.
Note!
Although PASS can be checked for proper operation, most performance properties of the PASS can not be tested by the
end user in the field.
7. With the cylinder valve still open and the positive pressure turned off, check that the cylinder pressure is indicated on the
DDU and in the HUD.
8. Read the pressure on the mechanical pressure gauge.
