G1 Industrial SCBA
US
4.2
Regulator
(1) Ensure that no moisture or debris is present inside the regulator.
(2) Ensure that the o-ring and seal ring are present and free of debris and damage.
(3) If the SCBA is equipped with a quick connect hose:
a) Inspect the quick connect fittings.
b) Ensure that the openings are clear and free of debris and other contaminants.
c) Ensure that the quick connect fittings operate properly and are secured.
4.3
Pressure Reducer
(1) Threaded Connect:
a) Unthread the handwheel coupling nut from the cylinder valve (if equipped).
b) Inspect the coupling nut for thread damage.
c) Before attaching the cylinder valve to the pressure reducer, check that the cylinder connection
o-ring is present and free of damage. If the o-ring is damaged, it must be replaced before the
SCBA is used.
d) Thread the handwheel coupling nut onto the cylinder valve threads. The handwheel should be
hand-tight (no tools).
(2) Quick Connect:
a) Turn the quick connect grip counterclockwise and push towards the pressure reducer to
release (if equipped).
b) Before attaching the cylinder valve to the pressure reducer, ensure there is no dirt or debris
on the coupling and adapter. Ensure the adapter on the cylinder valve is tight.
c) Push the cylinder valve with adapter onto the quick connect coupling until an audible snap is
heard. The handgrip will rapidly rotate indicating that the cylinder valve is connected to the
pressure reducer. Pull the cylinder valve firmly away from the pressure reducer to ensure the
handwheel is fully attached.
(3) Ensure that the bell is properly aligned and that the screws are tight. The bell should not be able
to be rotated or loose. If the bell is loose or can rotate, remove the SCBA from service.
(4) Inspect the pressure relief valve (if equipped). Ensure that the relief holes are clear and free of
debris or other contaminants. Ensure that the pressure relief valve is properly secured.
(5) Inspect the hose connections. Ensure that the hoses are properly secured.
