FUNCTIONAL CHECKS

(After Each Use and Monthly)
1. Check that the regulator works properly.
a. Sanitize the regulator outlet before and after testing.
b. Check that the cylinder valve and second stage
shut-off are closed and the system is not pressur-
ized.
c. Gently inhale through the regulator outlet and hold
your breath for about 10 seconds. If negative pres-
sure is maintained, there is no leakage.
d. Gently exhale through the regulator outlet for about
10 seconds. If positive pressure is maintained, there
is no leakage.
e. Do not use the apparatus if airflow through the reg-
ulator is detected in either test. Return the regulator
to a certified repairperson.
2. Inspect the Second Stage Shut-Off.
a. With the regulator pressurized, operate each valve
to be sure it operates. Venting of pressure relief
valves (or a continuing flow of air through the regu-
lator when the user is not inhaling) indicates that the
regulator needs to be repaired.
FUNCTIONAL CHECKS
DO NOT disconnect when pressurized. Release all
pressure from the regulator by opening the bypass
valve. Removing the regulator when pressurized can
result in serious personal injury, death, or damage to
equipment.

b. Listen to the regulator. Any unusual sounds, such as
whistling, chattering, clicking, or rattling mean that
the regulator should be checked further.
c. If any of these symptoms occur, the apparatus must
be removed from service. Return the regulator to a
certified repairperson.
