(e) Connect L. P. line to regulator. Insert tubing into fitting until ferrule seats in fitting. Tighten
the nut by hand and then one quarter turn with a wrench. If fitting is relatively new the nut
might be turned 3/4 of a turn. Follow up by snugging the nut slightly with a wrench.
NO
TE: Apply teflon tape to all tapered male threads as advised above.
(f) Connect H. P. feed/recharge and relief lines to regulator. Insert tubing into fitting until
ferrule seats in fitting. Tighten the nut by hand and then one quarter turn with a wrench. If
fitting is relatively new the nut might be turned 3/4 of a turn. Follow up by snugging the nut
slightly with a wrench.
(g) Unsafety valve on cylinder. Check that valve remains in OFF position.
(h) Check pressure and refill bottle as necessary.
(i) Inspect for leaks, especially at fittings that have been separated.
(j) Reinstall finished bulkhead in aft cabin, secure with screws.
(k) If used, remove tailstand from airplane.
B. Recharge Valve (See Figure 2.)
(1) Removal
The recharge valve is located on the left rear side of the aircraft and is covered by its own
access door. This valve is connected to a T-fitting which interconnects the H. P. line from the
regulator and the H. P. gauge feeder line. Accordingly, the recharge valve and its line are under
constant cylinder pressure as long as the H. P. line is connected to the regulator.
(a) Remove oxygen cylinder (see above) before attempting work on the recharge valve
assembly. Removal of the oxygen cylinder mounting shelf is also recommended to
further improve access.
NOTE: Continuous pressure is applied to high pressure line until it is disconnected from
cylinder. A check valve will close when high pressure line is disconnected from
cylinder. The closing of this valve is frequently accompanied by a loud popping
sound.
(b) Remove screws securing the recharge valve shroud to the valve mounting dish and slide
the shroud back up the high pressure line.
(c) Disconnect the high pressure line from the recharge valve assembly. Cap line immediately
after removal.
(d) Remove three screws from recharge valve mounting plate.
(e) Remove valve from airplane.
(2) Installation
NO
TE: Apply teflon tape to all tapered male threads as cautioned in paragraph A, 4.
(a) Insert valve assembly into hole in mounting dish.
(b) Align screw holes in valve mounting plate with those in mounting dish.
(c) Install the three mounting screws. Attach cap chain, with information plate attached, with
one of the screws.
CAUTION: CONNECT HIGH PRESSURE LINE TO VALVE BEFORE CONNECTING TO
CYLINDER.
(d) Connect H. P. line to valve. Torque to 30 - 150 in. lbs.
(e) Slide shroud down H. P. line and secure with screws (3).
(f) Reinstall oxygen cylinder (and mounting shelf, if previously removed), per Oxygen Cyliner,
Installation, above.
