corners and work to middle. Squeeze on to gasket track if it appears to be
too long. Don't wait to the last 3-5 inches to compress what may appear to
be excess. It may help to set glass in place, install cover rail in place and
install 4-6 screws in place. Just have screws barely touching frame and do
not tighten for overnight cure (drying). In the morning, take off frame and
glass, checking gasket for good seal. If there is a loose place, put acetone
in a spray mist bottle and pull loose area slightly away and mist. The
acetone will reactivate glue and reseal back together. Let set an hour or
two and reassemble glass and frame.
 Place a small amount of vacuum grease on top edge of gasket and wipe off
excess. Replace glass, install cover plate, then start one screw in each
corner and add one screw on each side as you go around, adding one screw
to a side at a time (only starting each one, do not tighten). When all screws
are started, tighten screws to only touch the cover frame. Start in each
corner and only snug each screw (1/4 to 1/2 turn) carefully and do not over
tighten. In same pattern as starting screws, slightly snug a screw on each
side, one at a time, all the way around (follow numerical pattern below) in
a diagonal pattern. Continue to do this until all screws are tight, but not
overly tight. This procedure is important so glass does not crack with too
much tension in one spot. Evenly tighten all screws.
 Glove ports should be removed and retightened in similar procedure. Use a
thin film of vacuum grease on port gasket, do not use excess amount.
Clean old vacuum grease off port area before assembly.
