Installation and Maintenance
CAUTION
1. The roof top air conditioner must be mounted on a level plane
from front to rear and side to side when the vehicle is parked on a
level plane. Fig. 4 shows maximum allowable degrees that the unit
can be mounted above or below level.
2.If the roof of the vehicle is sloped (not level) such that the roof top
air conditioner cannot be mounted within the maximum allowable
degree specifications, an exterior leveling shim will need to be
added to make the unit level. A typical leveling shim is shown in Fig.
5.
3.Once the roof top air conditioner has been leveled, some
additional shimming may be required above the interior ceiling
assembly. The roof top air conditioner and the interior ceiling
assembly must be square with each other before they are secured
together.
4.After the mounting hole area is properly prepared, remove the
carton and shipping pads from around the roof top air conditioner.
Carefully lift the unit on top of the vehicle. Do not use the outer
plastic shroud for lifting. Place the roof top air conditioner over the
prepared mounting hole.
5.The front section of outdoor unit of air conditioner must be in the
same direction as the vehicle,which is useful for reducing wind
resistance.
