1. Lifting plates (quantity of (4) per shipping split;
rear plates not shown)
2. Splice plates
3. Front vertical post
1. Position the equipment - Position the equipment
or sections of equipment in their final location.
If the equipment line-up was split into two or
more shipping sections, it is necessary to first
match, line up, and reassemble the multiple
sections into an integrated equipment assembly.
2. Apply gasket material - After removal of the
lifting plates (see Figure 59), it is necessary to
apply the presstite gasket material, Figures 59
and 60, to the mounting surface of the roof
flange. The gasket material is supplied with
the equipment.
3. Align sections - Align the two sections with
the mating surfaces butted together.
4. Fasten sections together - Referring to Figure
50, the mating sections of the outdoor enclosure
should be immediately bolted together including
the front and rear vertical posts and the roof
flange. Each vertical post will require ten 3/8-16 x
1-inch bolt assemblies, see Figure 59; the roof
flange will require either eleven or twelve ¼-20 x
1/2-inch thread forming bolts. The bolts should
be tightened with a torque of 7-9 ft-lbs. Figure 60
is a cross-sectional view of the assembled
roof joint.
