3.2.2 Body Insulation 1. Remove the long, 1.5-inch wide, strip of insulation for the side panel from the
Installation lid insulation pad.
2. To adjust the length of the insulation pad (or the side panel), tear the insulation
along the perforations from the end(s) of the pad to fit either the 18-inch ver-
sion or the Legacy
®
version of the enclosure.
3. Position the pad around the press nuts in the center of the body by folding the
pad along its length. Position the insulation punch-out(s) to closely match the
position of the press nuts.
4. Remove the adhesive backing, and carefully lay the insulation in the body of
the enclosure, pressing firmly, taking care not to crease the insulation.
5. Then apply the side strip to the side of the enclosure body that does not con-
tain the “T-slot”. (See Figure 3.)
6. The insulation is very soft and will conform as needed during the installation of
the camera and lens.
7. Snap the gas spring ball joint to the lid, and close the enclosure.
