G1 Integrated SCBA System
Threaded connect:
Thread cylinder valve onto pressure reducer, if necessary, bring the SCBA with valve up into
a vertical position.
alphaCLICK 2 connect:
Align the compressed air cylinder with the alphaCLICK 2 axially to the coupling and fit on the
alphaCLICK 2 coupling.
Close the coupling by pushing together using a light force and checking that the arrow of the
indicator ring is vertically aligned with the backplate.
CAUTION!
Never push the coupling system together using excessive force.
(13) Tighten cylinder strap by pulling the free end.
NOTICE
Do not overtighten the cylinder strap! Damage can occur when using excessive force to close the
cylinder buckle and the SCBA might not be ready for use. The final fastening tension will be
achieved when closing the cylinder buckle.
(14) Check position of compressed air cylinder, retighten if necessary.
(15) Hinge cylinder buckle down until it catches.
(16) Fasten end of the cylinder retaining strap onto Velcro strip.
(17) Briefly open cylinder valve and check for escaping air, retighten if necessary.
(18) To check that the cylinder is secure, place one hand on the backplate and grasp the cylinder
valve with the other hand. Try to pull the cylinder and valve down and out away from the
carrier. Make sure that the strap holds the cylinder securely in the carrier.
NOTE:
If the cylinder feels loose, check that the latch engages with the proper slot on the band.
Ensure that the latch is fully tightened. Do not use the SCBA if the cylinder is not held securely in
the carrier.
(19) Align the handwheel assembly to the cylinder valve.
Threaded connect:
Before installing the threaded handwheel, check that the O-ring inside the handwheel coupling
nut is present and free of damage. If the O-ring is damaged, it must be replaced before the
SCBA is used.
Thread the handwheel coupling nut onto the cylinder threads. The handwheel should be hand-
tight (no tools).
alphaCLICK 2 connect:
Before installing ensure there is no dirt or debris on either the male or female end of the
coupling. Ensure the adapter on the cylinder valve is tight.
Push the quick connect coupling onto the cylinder valve adapter until an audible snap is heard.
The handgrip will rapidly rotate approx. 45° counter clockwise indicating that the valve is
connected to the pressure regulator.
Grasp the handwheel firmly and pull on it to ensure the handwheel is fully attached.
