(3) Do these steps to install the body insulation [64] and forward insulation [63] to the air
separation module [1]:
(a) Make sure that there is a clearance of 0.15 ±0.10 in. (3.8 ±2.5 mm) between each bracket
and cutouts (on the body insulation [64]).
WARNING
DO NOT GET ISOPROPYL ALCOHOL IN YOUR MOUTH, EYES, OR ON
YOUR SKIN. DO NOT BREATHE THE FUMES FROM THE ISOPROPYL
ALCOHOL. KEEP THE ISOPROPYL ALCOHOL AWAY FROM SPARKS,
FLAME, AND HEAT. ISOPROPYL ALCOHOL IS POISONOUS AND
FLAMMABLE, WHICH CAN CAUSE INJURIES TO PERSONS AND
DAMAGE TO EQUIPMENT.
(b) Clean the body insulation [64] with alcohol, B00130.
(c) Apply the 3 in. (76 mm) wide Jehier KB-23 tape, G50706, to the seams on the body
insulation [64].
1) Make sure that no insulation foam is exposed.
2) Make sure that the Jehier KB-23 tape, G50706, is centered between the insulation
sections.
a) The Jehier KB-23 tape, G50706, must extend a minimum of 1 in. (2.5 cm) on
each side of the seam.
NOTE: Small gaps no larger than 0.25 in. (6.4 mm) are acceptable along the
seam, as long as, the gap does not extend through the entire seam
and is covered by tape. The ASM surface must not be visible through
the gap.
(d) Make sure that there are no gaps between the foam and the outside diameter of the air
separation module [1], except where bunching occurs.
NOTE: Where bunching occurs, gaps less than 0.25 in. (6.35 mm) wide is permitted.
(e) Install the ties (ECC-A fiberglass tape, G51019, ECC-A fiberglass tape, G51020, or
ECC-B fiberglass tape, G51066) around the exterior surface of the insulation.
NOTE: Use a square knot on each tie (ECC-A fiberglass tape, G51019) to prevent
fraying. The loose ends of the tie must be tucked under the ties, between the tie
and the insulation. A knot shall also be placed on the end of the tie to prevent
fraying. The end of the insulation tie must be tucked under itself (between the tie
and foam) to prevent the ends from moving around during shipping, installation
or service.
1) Make sure that the ties (ECC-A fiberglass tape, G51019, ECC-A fiberglass tape,
G51020, or ECC-B fiberglass tape, G51066) are tightly attached to the insulation.
NOTE: Ties (ECC-A fiberglass tape, G51019) may push down on insulation
sufficiently to keep its location, but not to the extent that visible gaps occur.

(4) Do these steps to install the high flow valve [14] to the air separation module [1]:
(a) Apply the epoxy primer, C50285, to the groove where it comes in contact with the
strap [26].
