Note. The gasket is not rectangular. The side of the
gasket that is placed near the back of the ET unit is
shorter than the side that is placed near the front of the
unit.
3. Start at one corner and peel away just enough of the
backing to expose about 1 inch of adhesive on each
side of the corner.
Important
The adhesive under the backing is very delicate. To be sure
!
that you do not remove the adhesive with the backing, use a
razor knife to separate the backing from the adhesive.
Do not remove the entire backing at once. Start at one corner,
!
lift and peel back some of the backing only, as described
below.
Do not stretch the gasket. This can cause the adhesive layer
!
to come away from the gasket.
4. Place the gasket on the recessed edge of the access
hatch, with the backing side down. Line it up with the
edge of the opening in the access hatch, then gently
press the corner with the exposed adhesive into place.
Don't press it down firmly yet.
5. With the gasket gently adhering at the corner, peel the
backing away from the corner carefully, a little bit at a
time, gently pressing the gasket into place around the
edge of the access hatch as you go along. Don't press
it down firmly yet.
6. Continue until you have removed all of the backing
and the gasket is lightly tacked into place around the
opening of the access hatch.
7. Make sure that the entire surface of the gasket is in
contact with the recessed edge of the access hatch,
without bumps or ripples.

8. When you are satisfied with the fit, use your fingers to
press the gasket firmly into place all around the
opening of the access hatch.
Preparing the hatch for cables
You can make up to four openings through the back of the
hatch.
Do not make openings in the removable plate, the top or
bottom of the hatch, nor in the extended hatch cover (if you
are using the extended hatch cover).
Important
Be sure that the openings you make are free of burrs and that the
surface around the hole is smooth and free of debris. This will
help ensure that the installed fittings seal properly.
If you want to make your own cables, refer to pin-outs in
the user's guide for your ET unit.
Connecting cables to the hatch
To ensure safe, certifiable connections and a complete seal
using one of the sealed fittings provided
(Table A), follow the steps in this section.
