(3) Withdraw the paper. Resistance to the withdrawal of the paper indicates proper
seal pressure. If there is no resistance, perform the adjustment procedure con-
tained in the following paragraphs.
(4) If there is resistance to the withdrawal at all of the test points, sufficient seal
pressure exists on the silicone weather gasket and adjustments are not neces-
sary.
Adjust. (Figure 3-20) Adjustment to increase the seal pressure on the silicone
gasket can be made on the hinged side of the door and on the roller latch side of the
described in the following paragraphs:
(1) Weather Gasket Pressure Adjustment. To increase the weather gasket pressure
on the hinged side of the door, proceed as follows
(a) Open the door and remove and retain three bolts (1), six flat washers
(2), and three self-locking nuts (3) attaching the hinge to the door.
(b) Coat each new shim with conductive compound on both sides.
( c )
Insert shim (4), approximately 0.032 inches thick and matching the hinge
body in size, between the hinge leaf and the door.
(d) Secure the hinge leaf to the door using three bolts (1), six flat washers
(2), and three self-locking nuts (3).
(e) Repeat the test procedures of paragraph 3-18.b. and repeat this adjustment
procedure as necessary.
(f) After completion of adjustment procedure, apply a continuous bead of
sealer around shim (4) and hinge leaf, and around head of bolts (1).
(2)
Seal Pressure Adjustment. To increase the seal pressure on the roller latch
side of the door, proceed as follows
(a) Open the door and remove and retain the hex head screws (5 and 6), flat
washers (7), and lock washers (8) from the top and bottom hole attaching
the keeper (9) to the wall, and remove keeper and shim (10). Remove
detent pin (11) from center keeper.
NOTE
If more than one shim (12) is required, additional shims may be
added, up to a maximum thickness of 0.096 inches.
If the seals are not tight after the maximum allowable thickness is
obtained, the seal should be replaced as the material has likely
broken down.
(b) Add a 0.032 inch shim between the keeper (9) and the shelter.
