Preparing the New Glass

! CAUTION
The laminated front screen must be handled with extra
care to prevent breakage. Wherever possible, store and
handle it in a vertical attitude. When placing or lifting the
screen in a horizontal attitude it must be supported over
its whole area, not just at the edges.

1 Make sure that the new glass correctly fits the frame
aperture K.
a Put two spacer blocks L onto the bottom part of the
frame aperture.
b Install the new glass on the spacer blocks - ALWAYS
USE GLASS LIFTERS M (see Service Tools). Check
that there is an equal sized gap all round the edge of
the glass.
Note: The spacer blocks are rectangular in section to give
two common gap widths. If necessary they can be trimmed
to a smaller size to give an equal sized gap around the glass.
IMPORTANT: The glass edges MUST NOT touch the frame,
otherwise movement of the frame will chip and eventually
break the newly installed glass.
2 After checking for size, remove the new glass and place
it on a purpose made glass stand N (see Service
Tools).
Small panes of glass will need locating on a 600 x 700 mm x
15 to 19 mm thick plywood board P (sourced locally to fit
the glass stand N). It is recommended that an access hole is
cut in the board to accommodate the glass lifter, making it
easier and safer to handle small panes of glass. The board
should be covered with felt or carpet to give an anti-scratch
surface. Resting the glass on four spacer blocks will ensure
clearance of the cartridge nozzle tip during application of the
polyurethane sealant.
3 Make sure the glass is positioned on the stand the
correct way up (i.e. with the black ceramic ink band
upwards) ready for application of primer etc.
a Use ' Active Wipe 205' to thoroughly clean and
4
' prime' the black ceramic ink band printed on the
glass (see Note 1). Use a lint free cloth to apply the
'Active Wipe 205', allow 5 minutes flash off (drying)
time.
Note 1: Do not touch the glass after cleaning with the
'Active Wipe 205'.
b If the glass does not have a black ceramic ink band,
paint a band on the glass using 'Black Primer 206J'.
The band should be approximately 25mm (1in) wide,
and the edge should be a neat straight line as shown
at R.
