TO THE INFLATION RESERVOIR, WHICH IS KEPT BELOW THE ESCAPE-SLIDE,
OR TO THE SURFACE MATERIAL.

(a) Carefully pull the electrical harness (22) to disconnect the quick-release connector (23).

NOTE: The quick-release connector (23) is in the burr strips (VELCRO) on the pack-assembly soft-cover (12).

(b) Release the inflated escape-slide raft (7) from the aircraft:
1 Make sure that the ground area, where you will lower the escape-slide raft (7), is clean and clear from sharp objects.
(c) Pull open the burr strips of the girt assembly (11).

Procedure 1: With burr strips (VELCRO)
Procedure 2: With dual-lock reclosable fastener-strips
Procedure 3: With spring-loaded bolts.

The three different procedures are not interchangeable.
More force is necessary to open the dual-lock reclosable fastener-strips than to open the burr strips. You hear a click when the two halves open.

(a) Release the straps (21) from the straps on the bottom inner edge of the decorative cover (20).
(b) For procedure 1 and 2:
