3.2.2.1. Installing Quick Connect Adaptor to Cylinder
(1) Use only a fully charged cylinder and inspect the internal thread of the
cylinder valve to ensure it is not damaged and free of dirt and debris.
•
The threaded connection of the cylinder valve must be undamaged and
free from dirt and debris.
•
If the cylinder valve is damaged, remove from service and return it to a
MSA trained or certified repair technician.
(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.
