When replacing cylinder valves or after retesting of
cylinders, make sure the proper cylinder valve, burst disc,
and gasket are installed prior to cylinder recharging.
Establish the service pressure of the cylinder. Type 3AA
(steel) cylinders that bear a plus (+) sign after the latest
retest date may be recharged to a pressure 10% greater
than the stamped service pressure, i.e., a cylinder
stamped 3AA2015 with a plus (+) sign after the latest test
date may be recharged to 2216 psig (this applies to steel
cylinders only). Steel cylinders without a plus (+) sign
stamped after the latest test date must be removed from
service. All other cylinders which are not type 3AA shall be
filled to the designated service pressure only (as found on
the DOT approval label or stamping). Appropriately
connect the cylinder to the filling recharge system and
refill. Terminate the filling when the pressure reaches
service pressure and allow the cylinder to cool to room
temperature.
If necessary, top-off the cylinder such that service
pressure is attained with the cylinder at a temperature of
70°F. Close the valves on the cylinder and the recharge
system and remove the cylinder. Apply a soap solution to
determine if there is any leakage between the cylinder and
the valve. If there is no leakage, the cylinder is now ready
for re-use.

REMOVING THE APPARATUS
12
STORAGE
Do not store the apparatus or spare cylinders within or
near an area where the apparatus can or might be
exposed to any substances that will or might attach any
part of the apparatus, causing the apparatus NOT to
perform as designed and approved.
Be careful not to drop cylinder or bump 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 apparatus with an empty or partly filled
cylinder. Always install a fully-charged cylinder so that the
apparatus is ready for use. Complete Inspection and
Cleaning and Disinfecting Procedures are outlined in this
manual. Ensure the complete apparatus is clean and dry.
Ensure the facepiece head harness adjustment straps are
fully extended. Place the complete apparatus in the
storage case or suitable storage location so it can be
easily reached for emergency use.
