Preparing the New Glass (cont'd)
5
Install the Ultra Fast Adhesive cartridge (see
Sealing
and Retaining Compounds
and Note 2 below) into a
suitable applicator gun:
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 shown at
S
.
e
Install the cartridge in the applicator gun.
Note 2:
Cold material will be very difficult to extrude. The
cartridges must be pre-heated in a special oven (see
Service Tools
) 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.
6
Apply the pre-heated adhesive to the glass (do not start
in a corner). Keep the nozzle guide
T
against the edge
of the glass and make sure that the adhesive forms a
continuous 'pyramid' shape.
Note 3:
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
Make sure the two spacer blocks are in position (see
step 1 of
Preparing the New Glass
).
2
Install the glass in the frame aperture:
a
ALWAYS use the special lifting tools when moving
the glass. Use a lifting strap to hold large panes of
glass in position as shown
W
.
b
Sit the bottom edge of the glass on the spacer
blocks as shown
X
.
c
Make sure that the glass is correctly positioned, then
gently press around the edges of the glass and
ensure full adhesive contact is achieved. Do not
press too hard or too much adhesive will squeeze
out.
