ALLOWABLE OFFSET FOR ALL AIR CONDITIONERS WITH ROTARY COMPRESSORS
If the roof of the vehicle is sloped (not level) such
that the air conditioner cannot be mounted within the
maximum allowable degree deviations, an exterior
leveling shim will need to be added to make the air
conditioner level. A typical front to back leveling
shim is shown in Figure 3.

V. SECURING THE AIR CONDITIONER TO THE ROOF
A mounting frame is supplied with the ceiling assembly.
Follow the steps below to secure the air conditioner to the
roof. Refer to Figure 4.
A.
Locate the air conditioner mount gasket over the
opening in the roof.
B.
Install the ceiling assembly mount frame using the
four bolts found with the ceiling assembly. The
9400 series ceiling assemblies also utilize mounting
springs and washers over the bolts (See Figure 4).

Once the air conditioner has been leveled, some
additional shimming may be required above the
interior ceiling assembly. The air conditioner and
the interior ceiling assembly must have a squared
installation relationship before they are secured
together.
After the mounting hole is properly prepared, remove
the carton and shipping pads from around the air
conditioner. Carefully lift the unit to the top of the
vehicle. Do not use the outer plastic shroud for
lifting. Place the air conditioner over the prepared
mounting hole. The pointed end (nose) of the shroud
must face towards the front of the vehicle. Pull the
electrical conduit down from the air conditioner
through the mounting opening and let hang.
When mounting springs are utilized, proper tension
has been achieved for each bolt when the spring coils
have just come together. When mounting springs are
not utilized, proper tension has been achieved for
each bolt when any portion of each gasket indicating
tab has been pulled down even with the roof. See
Figure 4. The upper unit has now been properly
installed with optimum gasket compression.
