Filling The M.a.s. From A Scuba Cylinder - Aqua Lung Micra Air System User Manual

10 Micra Air System Owner's Manual
CAUTION: If moisture is found to be present inside the port
opening, indicating that water may have entered the M.A.S.
first-stage and cylinder, DO NOT fill or attempt to use the
M.A.S. until it has received complete inspection and any
required service by an Authorized Aqua Lung Dealer.

FILLING THE M.A.S. FROM A SCUBA CYLINDER

NOTE: The H.A.B.D. system, sold under P/N 1028-00, does
not include a fill adapter. The fill adapter (P/N 1006-55) may
be purchased separately. (Refer to Figure 1 shown on page
7 for component identification.)
1. With a pressure gauge that has been determined to be
accurate, check the pressure of the supply cylinder to
ensure that it contains at least 2,800 psi and no more
than 3,100 psi. It is very important to ensure that the
M.A.S. is filled to its total capacity, but not overfilled.
2. Remove the protector cap from the threaded nozzle of
the fill adapter. Inspect the nozzle to ensure the O-ring
is present and seated evenly at the base of the threads.
NOTE: The pressure gauge assembly
may be placed inside the cap to prevent
loss or damage while filling the M.A.S.
3. Mate the threaded nozzle of the fill adapter into the open
HP port, and turn clockwise by hand until snug. DO
NOT apply a wrench or otherwise overtighten the fill
adapter into the first-stage.
4. Loosen the fill adapter yoke screw as needed so that the
dust cap can be removed from the inlet fitting and the
yoke can be placed over the valve of the supply cylinder.
5. While supporting the M.A.S. with one hand, place the
yoke of the fill adapter over the cylinder valve to align
the inlet fitting flush against the valve O-ring. Tighten
the fill adapter yoke screw clockwise into the small
dimple on the backside of the cylinder valve only until
finger snug. (See Fig. 6.)
