3.1 Mounting the First Stage Onto the Cylinder Valve
3.1.1 Yoke Connector
Partially loosen the yoke screw of the first stage regula-
tor so that the dust cap can be removed from the filter
and air inlet.
With the cylinder valve facing away from you, release a small amount of air from
the cylinder by turning the handwheel counter-clockwise to open the valve only
slightly. When air is heard exiting, immediately close the valve. This will clear any
moisture or debris that may be inside the cylinder valve outlet opening.
Check the condition of the cylinder valve O-ring
Place the first stage regulator over the cylinder valve so
that the inlet fitting aligns with the O-ring of the cylinder
valve, and the LP hose of the primary second-stage will
be routed over the right shoulder. While holding the
first stage in place, turn the yoke screw clockwise. Ensure that the yoke screw
mates into the small dimple on the backside of the cylinder valve, and tighten
finger-tight only.
3.1.2 DIN Connector
Remove the protector cap from the cylinder valve.
With the cylinder valve facing away from you, release a
small amount of air from the cylinder by turning the
handwheel counter-clockwise to open the valve slightly.
When air is heard exiting, immediately close the valve. This will clear any mois-
ture or debris that may be inside the threaded cylinder valve opening.
Check the condition of the cylinder valve O-ring.
Position the first stage near the cylinder valve so that
the LP hose of the primary second-stage will be routed
over the right shoulder. Thread the first stage DIN
connector into the cylinder valve and turn the handw-
heel clockwise by hand until it is lightly snug. DO NOT
use tools to tighten.
