INSTALLATION INSTRUCTION
BEFORE INSTALLATION
T estrun the unit with proper power supply. Refer to the
operation instruction section in the Owner’s Manual
Operation & Installation. Make sure all the controls
operate correctly then disconnect the power supply
of the unit.
WARNING
!
Moving parts may cause personal injury. Be careful when test the unit. Do not operate the unit
with exterior cover removed.
STEP 1-SELECTING AN INSTALLATION LOCATION &
INSTALLING THE ROOF TOPAIR CONDITIONER
Your air conditioner has been designed for use in recreational vehicles.
Check the roof of the vehicle to determine if it can support both the roof top unit and the ceiling
assembly without additional support. Make sure the interior ceiling mounting area will not
interfere with existing structures.
Once the location for your air conditioner has been determined. A reinforced and framed roof
hole opening must be cut (if there is no hole) or you may use existing vent holes.
CASE A.
If a roof vent is already present in the desired mounting location for the air conditioner, the
following steps must be performed:
1. Remove all screws which secure the roof vent to the vehicle. Remove the vent and any
additional trim. Carefully remove all chalking from around the opening so the surface is
clear.
2. It may be necessary to seal some of the old roof vent mounting screw holes which may
fall outside of the air conditioner basepan gasket.
3. Examine the roof opening size, if the opening is small than 356x356mm, the opening
must be enlarged. If the opening exceeds 356x356mm, a mounting plate (frame) must
be fabricated to reduce the opening size (See Figure 1).
- 15-
● Before installation, please check whether the unit is assembled
with three pieces of rubber pads and square sealing strip.

356
356

25
Figure 1
If a roof vent opening is not used,a new opening(see figure 1)will be cut into the vehicl roof.
A matching opening will also have to be cut into the interior vehicle ceiling,be careful when
cutting the ceiling opening because if the ceiling opening is carpeted,snagging could occur. After
the opening in the roof and interior ceiling are the correct size,a framed support structure must
be placed between the exterior roof top and interior ceiling.The reinforced framed structure must
follow the follwing guidelines: 1. It must be capable of supporting both the
weight of the roof top air conditioner and
the interior ceiling assembly.
3.
There must be an opening through the
frame for the power supply wiring.Route
the supply wiring through the frame at the
same time the support frame is being
installed.
2. It must be capable of holding the roof outer
surface and interior ceiling apart and
supporting them, so that when the roof top
air conditioner and ceiling assembly are
bolted together,no collapsing occurs. A
typical support frame is shown in Figure 1.
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. Figure 2shows 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 Figure 3.
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 point end (nose) of the shroud must face toward the front of the vehicle.
