h Locate center of bus ceiling and mark.
i Centering the template against back wall and
ceiling, mark the bus ceiling and wall for evaporator
mounting holes and drain lines.
j Using a 3/16 drill bit, drill 4 holes through the bus
ceiling. The smaller bit will allow you to check the angle
of the hole and where you have exited the bus roof. If the
angle is incorrect, the 3/16th hole is easily repaired with
a pop-rivet.
k After determining the pilot hole is correct enlarge
the 4 holes to 7/16 inch. See Figure 2-4.

l Matching holes in reinforcing rails to holes in bus
roof, drop 3/8 inch carriage bolts through mounting rails
and the roof. The carriage bolts should drop through the
roof easily. You may have to open the holes slightly, Do
not force the bolts through the roof or ceiling.
Figure 2-5 Carriage Bolts & Sealant
m Pull reinforcing rails and carriage bolts away from
bus roof. Apply a bead of sealant down the center of
each rail and under the carriage bolt heads. See
Figure 2-6 and Figure 2-7.
