a Remove the aluminium disc cover from the base
of the cartridge and discard the 'dessicant
capsule'.
b Make sure that the rolled edge of the cartridge is
not damaged - if necessary, the edges should be
pressed flat, otherwise it will be difficult to remove
the cartridge from the applicator gun.
c Pierce the front 'nozzle' end of the cartridge to its
maximum diameter.
d Fit the pre-cut nozzle.
e Install the cartridge in the applicator gun.
Note: Cold material will be very difficult to extrude. The
cartridges must be pre-heated in a special oven for 1 hour
to a temperature of 80°C (176°F). Pre-heating the
cartridges makes the adhesive more workable and also
brings the 'curing' time down to 30 minutes.

start in a corner). Keep the nozzle guide A against the
edge of the glass and make sure that the adhesive

Note: Once the pre-heated adhesive has been applied to
the glass, install the glass in the aperture as soon as
possible. After approximately 10 minutes the sealant will
form a 'skin', this will prevent the glass from bonding.
7 After applying the adhesive, leave a small amount of
sealant protruding from the nozzle. This will prevent
any adhesive left in the cartridge from 'curing'.
Installing the New Glass
1 If the internal trim strip is damaged, renew it (cut to
length as required) before fitting the new glass. Make
sure the two spacer blocks are in position.
