THE REFRIGERANT
To realize the function of the unit, a special refrigerant circulates in the system. The
used refrigerant is the fluoride R32, which is specially cleaned. The refrigerant is
flammable and inodorous. Furthermore, it can lead to explosion under certain
conditions. But the flammability of the refrigerant is very low. It can be ignited only
by fire.
Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm
to the ozonosphere. The influence upon the greenhouse effect is also lower. R32
has got very good thermodynamic features which lead to a really high energy effi-
ciency. The units therefore need a less filling.
Appliance filled with flammable gas R32.

INSTALLATION
BEFORE INSTALLATION
Test run 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
1.Moving parts may cause personal injury. Be careful when test the unit. Do not operate the
unit with exterior cover removed.
2.Outdoor unit can't be installed at the low recess of the roof of vehicle. It must be mounted a
the flat surface on the roof of vehicle to make sure the rain, car-washing water, condensate
water, etc. can be drained smoothly. No water is allowed to be accumulated around the
outdoor unit; otherwise, it will cause malfunction or safety hazards as the water will pour into the
air conditioner.
1. Before sticking, clean up the sundries
at the sticking position (as shown in
Figure 1) of the chassis of the outdoor
unit to ensure that the sticking position
is clean;
2. Take out one piece of sponge (sealing
strip) and one piece of sponge from the
accessories, and tear off the paper on
the glue surface and align at the edge of
the position as shown in Figure 1 to stick
the sponge.
If the sponge (sealing strip) is damaged
or not stuck on the proper position, you
must replace it with a new one and stick
it properly;
3. Check whether the sponge (sealing strip)
and the sponge are tightly adhered, and
ensure that they will not fall off.

STEP 2-SELECTING AN INSTALLATION LOCATION &
INSTALLING THE ROOF TOP AIR 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.

- 11 -
Once the location for your air conditioner has been determined. A reinforced and framed roof.
Hole must be cut (if there is no hole, please refer to CASE B) or you may use existing vent
holes (See CASE A).
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 (14-1/4”)x(14-1/4”), the
opening must be enlarged.
CASE B.
If a roof vent opening is not used,a new opening(see figure 1-1)will be cut into the vehicle 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 following guidelines:
1. It must be capable of supporting both the
weight of the roof top air conditioner and
the interior ceiling assembly.
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 1-1 .
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.

ove Level 5°Max
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 2 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 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 front section of outdoor unit of air conditioner must be in the same direction as the vehicle,
which is useful for reducing wind resistance.
Note: Try you best to put the unit on the horizontal surface for operation. The unit can only operate for a short
time at the maximum sloping angle of 5° for preventing water leakage.

STEP 4-INSTALLING THE CEILING ASSEMBLY
Make sure that you have properly matched the roof top air conditioner and interior ceiling assembly.
Caution before tightening bolts:
1.The applicable thickness of vehicle roof ranges from 1.2”~3.1”.
2.Before tightening bolts, screw in the four bolts manually and prohibit screwing forcibly.
3.When screwing bolts, you can use automatic tool. Do not tighten one bolt completely and then
tighten other bolts, in order to prevent sticking of screw thread.
4.The max torque for tightening ranges from 2.3Nm~2.5Nm.
The following step by step instructions must be performed in the following sequence to ensure proper
installation.
1. Carefully take the ceiling assembly out of
the carton(The remote control packed with
the ceiling assembly).
2. Remove the ceiling grille from the ceiling
assembly.
Before the ceiling assembly can be
mounted to the roof top air conditioner, the
fabric duct collar must be fastened to the
basepan of the roof top air conditioner with
4 screws by upper duct plate (see Figure 5-
2、Figure 6-1、Figure 5、Figure 5-1).
Before lifting the ceiling assembly, pull the
4. fabric duct collar so it hangs out of the way
and does not get caught under the ceiling
assembly frame.
Secure the ceiling assembly frame to the roof
top air conditioner with the mounting bolts
(see Figure 5).You must start (thread) the
mounting bolts by hand to avoid cross-
threading. DO NOT START THE MOUNTING
BOLTS WITH AN AIR GUN.The mounting
bolts should be tightened, process is
completed when the basepan gasket has
been evenly compressed.
Set the fabric air duct into the duct opening
of installation plate sub-assy and cut off four
corner of fabric air duct. Because the
thickness of vehicle top is different, the
distance between the opening and the
installation plate sub-assy is shown in figure
6.
Fasten each side of the fabric duct with fitting
the bottom duct plate to the ceiling assembly
frame with 4 screws (see Figure 6).Trim any
excess fabric that may extend beyond edge
of bottom duct plate.
