(2) Inspect the external threads of the cylinder adaptor and the nipple of the
male connector on the pressure reducer to ensure they are not damaged
and free of dirt and debris.
Ensure that the O-ring is installed on the cylinder adaptor and it is
undamaged and free of dirt and debris.
(3) Thread the adaptor with a specific torque of 20-30 Nm into the cylinder
valve.
(4) Before installing, ensure there is no dirt or debris on either the male or
female end of the coupling. Ensure the adaptor on the cylinder valve is tight.
(5) Push the quick connect coupling (using light force) onto the male adaptor of
the pressure reducer until an audible snap is heard. The handwheel will
rapidly rotate approx. 45° counter-clockwise indicating that the valve is
connected to the pressure reducer.
(6) Grasp the handwheel firmly and pull on it to ensure the handwheel is fully
attached.

(1) If necessary, thread the alphaCLICK 2 cylinder adaptor with a specific torque
of 20-30 Nm into the cylinder valve ( Section 5).
(2) Place compressed air breathing apparatus horizontally so that the back face
is uppermost ( Fig. 17).
(3) Bring cylinder separator (1) into a horizontal position opposite the cylinder
buckle (4) until it catches.
When fitting the compressed air cylinder on the coupling of the
pressure reducer, it may tip down. In this case, support the pressure
reducer with your hand.
