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.

Figure 1

CAUTION

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.

Make sure that you have properly matched the roof top air conditioner and interior ceiling assembly. The following

step by step instructions must be performed in the following sequence to insure proper installation.

OF CEILING UNIT

STEP 2 - INSTALLING THE CEILING ASSEMBLY

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).

Figure 4

OWNER’S GUIDE -10

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.

8 9

MAKE SURE THAT ALL POWER SUPPLY TO THE UNIT IS DISCONNECTED BEFORE PERFORMING ANY WORK ON THE

UNIT TO AVOID THE POSSIBILITY OF SHOCK OR INJURY AND/OR DAMAGE TO THE EQUIPMENT.

WARNING

ROUTING 115V AC WIRING

After the interior ceiling assembly frame is properly secured to the roof top air conditioner, the following electrical

connections must be performed.

Figure 5

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.
