AIR SWEEP CONTROL
Your unit provides an automatic air sweep to cool the room
more efficiently. When the air sweep switch is set on (|),
the horizontal blade moves slowly up and down and dis-
tributes the air around the room. The direction of the verti-
cal blades can be adjusted manually (make sure the air
sweep is off). With the air sweep in the off position, the
horizontal blade can be closed by pushing the PUSH mark
on the blade, and can be opened by pushing it again.

Keep the unit’s air filters clean. (See the Normal
Maintenance Procedures section of this manual
on page 13)
Select the thermostat setting that suits your comfort
needs and leave it at that chosen setting.
Your unit provides you with more efficient cooling
air with the direct air discharger. On extremely hot
days or after much activity, you can take an “air
shower” and cool off quickly.
You can enjoy direct air by rotating the knob to
the open position and closing the front or rear
horizontal blade. (Closing the front blade may
provide direct air more efficiently)

Moving parts can cause personal injury. Be careful when test-running the unit.
Do not operate the unit with exterior cover removed.
WARNING

During extreme outdoor temperatures, the heat gain
of the vehicle may be reduced by:
- parking the vehicle in a shaded area
- keeping the windows and doors closed
- avoiding the use of heat producing appliances
Test run the unit with proper power supply outlet. Refer to the Operating Instructions section in this Owner’s Guide.
Make sure all the controls operate correctly then disconnect the power supply of the unit.
Your Air V unit has been designed for use in recreational vehicles.
Check the roof of the vehicle to determine if it supports 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.
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.
- using window shades (binds and/or curtains)
For a more permanent solution to reduce the high
heat gain, window awnings and/or window glass
tinting should be considered.

INSTALLATION INSTRUCTIONS
BEFORE INSTALLATION
STEP 1 - SELECTING AN INSTALLATION LOCATION &
INSTALLING THE ROOF TOP AIR CONDITIONER
CASE A.
If a roof vent is already present in the desired mounting location for the air conditioner, the following steps must be
performed:
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.
Examine the roof opening size. If
the opening is smaller than 14”
14”, the opening must be
enlarged. If the opening
exceeds 14” 14”, a mounting
plate (frame) must be
fabricated to reduce the
opening size (See Figure 1).

OWNER’S GUIDE - 7
CASE B.
If a roof vent opening is not used, a new opening (See Figure 1) will have to 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:
Hole for Wires
• Allow 24” (working length) of supply wiring through the support frame and make sure that all wiring passing
through any mechanical structure must be protected from insulation chaffing using a rubber grommet or strain
relief.
• After the support frame is built and both the roof exterior and the interior ceiling are cut, make sure that the
electrical wiring can be routed to the control board. Seal the gap around the electrical supply wiring using a
rubber grommet.
• 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 Air V can be mounted above or
below level.

It must be capable of supporting both the weight
of the roof top air conditioner and the interior
ceiling assembly
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.
We recommend that the spacing between the
vehicle roof top and the interior ceiling top be no
less than 3/4”. A typical support frame is shown in
Figure 1.
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.
CAUTION

OWNER’S GUIDE - 8
• 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
Air V level. A typical leveling shim is shown in Figure 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.
• 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.
• The pointed end (nose) of the shroud must face toward
the front of the vehicle. From inside the vehicle, pull the
electrical harness down from the roof air conditioner
through the mounting opening and let it hang.

OWNER’S GUIDE -
Carefully take the ceiling assembly out of the
carton. (The controls are factory installed in the
ceiling assembly.)
Remove the ceiling grille from the ceiling assembly
frame.
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 air
conditioner with 4 screws (See 햲, Figure 4).
Before lifting (mounting) the ceiling assembly, check
the gasket on the underside of the roof top air
conditioner. The gasket must be centered over the
roof opening.
Before lifting the ceiling assembly, pull the 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 햳,
Figure 4). 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 evenly.
Do not over-tighten each bolt. The bolt tightening
process is complete when the basepan gasket
has been evenly compressed to 60%.
Pull the fabric duct collar through the ceiling
assembly frame opening and pull the four corners
to extend below the duct opening
(See 햴, Figure 4).

STEP 3 - ELECTRICAL WIRING
Pull fabric tight. This will prevent the material from
gathering inside the discharge duct.
Route a copper, with ground, supply wiring with
minimum, #12 AWG from its power source to the
junction box. Do not attach them at this time.
Take the roof top air conditioner electrical harness and
plug it into the side of the selector switch control box.
Make sure that the “ridged” side of the plug is aligned
and matched with the “ridged” side of the selector
switch control box connection. DO NOT USE EXCESSIVE
FORCE (See Figure 5).
Remove the junction box cover (1 screw). Take the
supply wire and slide it into the back of the junction box
through the strain relief that is provided.
DO NOT USE DUCT TAPE ON OR AROUND FABRIC DUCT COLLAR.
WARNING
Fasten each side of the fabric duct with fitting
the duct plate to the ceiling assembly plate with
5 screws (See 햵, Figure 4). Trim any excess fabric
that may extend beyond edge of duct plate.

CAUTION
WHEN USING INSULATED CABLES, STRIP THE OUTER JACKET
BACK TO EXPOSE 4-6 INCHES OF THE INSULATED LEADS. STRIP
THE INDIVIDUAL WIRE LEAD ENDS FOR THE CONNECTION.
(EXPOSE ABOUT 3/4” OF BARE WIRE.) THEN TIGHTEN UP ON
THE CABLE. DO NOT OVERTIGHTEN! THIS COULD RESULT IN
PINCHING THROUGH THE PLASTIC WIRE INSULATION AND
CAUSE A SHORT OR “HOT” WIRES. (YOU COULD GET
SHOCKED.) THE CLAMP IS INTENDED FOR STRAIN RELIEF OF
THE WIRES, AND SLIGHT PRESSURE IS USUALLY SUFFICIENT TO
ACCOMPLISH THIS.
