(5) Lift battery out of compartment.

(7) Remove the two screws securing acid recovery jar cover to bracket. Slide the acid jar assembly
upward off of the battery hold-down bar. Keep the jar upright in a vertical position.
C. Installation
(1) Keeping the jar upright in a vertical position, slide the acid jar assembly and bracket downward
on to the battery hold-down bar. Secure recovery jar cover to bracket with the two screws
previously removed.
(2) Install the vent hose that connects through the firewall at the acid recovery jar end.
(3) Place the battery into the compartment.
(4) Place battery manifold cover on battery and install battery hold down bolts.
(5) Install vent hose at battery manifold.
(6) Push rubber battery terminal boots back on, tighten wing nuts and connect battery cables.
(7) Install battery access plate to floor of forward baggage compartment.
D. Cleaning
(1) Battery
(a) Remove all accumulated contamination from the battery exterior with a stiff bristle brush.
(Do not use a metal brush or abrasive materials.) Wipe exterior of battery and interior of
manifold, including manifold top cover, with a cloth saturated with a solution of
bicarbonate of soda mixed - one part soda to twenty parts of water. (Check that cell plugs
are tight - do not allow soda solution to enter any cells.)
(b) Wash entire battery with clear water and dry thoroughly.
(c) Wash down the battery support and floor area, hold down supports, connectors and cable
ends with a soda solution followed by clear water. Dry entire area and component parts
thoroughly. Apply fresh acid resistant paint if required.
(2) Acid Recovery Jar and Vent Lines
(a) Visually inspect all vent lines for kinks, cracks, flexibility, and loose connections. Replace
only with special hoses from parts manual. (DO NOT REPLACE WITH ORDINARY
RUBBER HOSE.)
(b) Slowly pour the soda solution into the vent hose, still attached to the firewall fitting, using
a small funnel. The solution will flow out the bottom fuselage vent.
(c) Follow with a final purge of clear water to flush the vent line and then blow dry with low
pressure air. This ensures that the vent line is not kinked or restricted and that it is
neutralized.
(d) Wipe down the lower fuselage area surrounding the vent with soda solution and clear
water. Apply a fresh coat of high quality aircraft wax to entire area.
(e) Unscrew the bottom of the recovery jar and separate from the top. Remove jar pad and
empty jar contents into suitable container for safe disposal.
(f) Thoroughly wash and neutralize the jar, pad, top (including bracket), and the short length
of vent hose still attached to the jar top with a soda solution and a clear water rinse.
(g) Thoroughly dry all components and recharge the jar with 0.75 of bicarbonate of soda.
Place dry jar pad in the jar on top of the soda charge.
(h) Screw jar back together and keep it in a vertical position.
(i) Install in aircraft per preceding installation instructions.
