3.5 During Use
Periodically check the pressure indicated on a chest mounted pressure indicator
during use.
When the needle on the pressure indicator reaches the red zone on the gauge
face, the primary low pressure warning device alarms.
The primary low pressure warning device indicates when cylinder pressure drops
below these approximate values:
• 55bar ±5bar for a 300bar system
Immediately return to a non-hazardous atmosphere if:
• SCBA free-flows (provides air when not inhaling).
• Low pressure warning device sounds.
• When the pressure warning device indicates 35% cylinder pressure,
immediately return to a non-hazardous atmosphere.
• If the air flow in the SCBA is reduced: Immediately keep purge pressed.
Immediately return to a non-hazardous atmosphere.

on the strap. Ensure that the latch is fully tightened. Do not use the SCBA if the
cylinder is not held securely in the carrier.
12. Align the handwheel assembly to the cylinder valve.
Threaded connection:
○ Before installing the threaded handwheel, check that the O-ring
inside the handwheel coupling nut is present, clean and free of
damage. If the O-ring is damaged, it must be replaced before the
SCBA is used.
○ Thread the handwheel onto the cylinder threads. The handwheel
should be hand-tight (no tools).
alphaCLICK2 connection:
○ Before installing check that the male and female end of the
coupling are clean and free of damage. Ensure the adapter on
the cylinder valve is tight (torque 20 to 30Nm).
○ If necessary, thread the alphaCLICK2 cylinder adapter with a
specific torque of 20 to 30Nm into the cylinder valve.
○ Push the alphaCLICK2 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.
○ Grab the handwheel firmly and pull on it to ensure the handwheel
is fully attached.
Attaching Two Cylinders
CAUTION!

5 Storage
WARNING!
DO NOT drop the cylinder or bump the valve knob. An unsecured cylinder can
become an airborne projectile under its own pressure if the valve is opened even
slightly.
Failure to follow this warning can result in serious personal injury or death.
• Do not store the SCBA or spare cylinders within or near an area where the
SCBA can or might be exposed to any substances and ambient conditions
that will or might attack any part of the SCBA, causing the SCBA to not
perform as designed and approved.
• Prior to storing the SCBA in a jumpseat, ensure there is no interference
between the SCBA and the seat. Ensure the SCBA and cylinder can be
removed easily without damaging the components.
• Do not store the SCBA for extended periods with the batteries installed in
the electronic components (if available) if the SCBA is not intended for
service. If the SCBA is in service, ensure that the batteries in the
electronic components (if available) have an adequate charge.
• Do not store the SCBA with an empty or partially filled cylinder. Always
install a fully-charged cylinder so that the SCBA is ready for use.
• Ensure the entire SCBA is clean and dry.
• Ensure the SCBA harness and full face mask head harness adjustment
straps are fully extended. Place the complete SCBA in the storage case or
suitable storage location so it can be easily reached for emergency use.
• For prolonged storage of the SCBA, remove the batteries from all
electronic components (if available) and housings to prevent battery
corrosion. Store the units in a cool, dry place.
