Replace (figure 4-4)
Gaskets must be replaced when a permanent set occurs and the seal is no longer
reliable. Weather gaskets can be found on the door assembly and emergency exit (inlet
assembly). Replacement procedures are the same for all weather gaskets.
(1) Carefully remove gasket and scrape channel clean.
(2) Remove residue using solvent.
Adhesive must be applied between 30 minutes and eight hours after application of primer.
If original primer coat was not damaged during removal of old gasket, it is not necessary
to apply new coat of primer.
(3) Apply primer, then adhesive, evenly to sides and bottom of gasket channel to insure a continuous bond.
(4) Immediately after applying adhesive, press new gasket into place.
(5) Clamp gasket around each comer to ensure good gasket contact with channel bottom while adhesive
cures. Gasket surface which mates with door jamb must be flat with no sharp discontinuities along its
length, corners or joint while adhesive cures.
