MODE SELECTOR BUTTON - Press this button to

select the desired mode. In COOL mode, the unit

will run at the normal cooling mode. In DRY mode,

the microcomputer of the unit controls the fan

motor and makes the unit automatically cycle on

and off according to the room temperature. This

enables the moisture to be removed more

efficiently. In FAN mode, only the fan will operate

at the selected fan speed and circulate the room

air. In FURN. mode, the unit will run at the normal

furnace mode. (This is a user-optional function.)

ON/OFF BUTTON - If you press this button, the unit

will begin operation. (You can hear receiving

beeps twice.) Press the button again, and opera-

tion stops. (You can hear a receiving beep.) If you

press this button immediately after turning off the

unit, the compressor will not operate for 3 minutes

to prevent overloading.

(If you have more than one air conditioning system in your vehicle, please note this section carefully.)

RECOMMENDED DIFFERENT PROTOCOL UNIT WHEN INSTALLS 2 UNITS TO ONE RECREATIONAL VEHICLE TO AVOID

SIMULTANEOUS OPERATING BY ONE REMOTE HAND SET SIGNAL.

COMPRESSOR DELAY function may be established at the time of installation of your Air V. If you have one air

conditioner, you need not use these functions. However, if your vehicle has more than one cooling system, depend-

ing on the manufacturing installation, you must use COMPRESSOR DELAY function to avoid simultaneous operating

the units which may cause the damage of power system of the vehicle.

COMPRESSOR DELAY FUNCTION

COMPRESSOR DELAY function is defined and preset by your manufacturer. (NO or 3SEC) The default is NO. To change

NO to 3SEC in your air conditioning unit, you must change the COMPRESSOR DELAY function switch of main printed

circuit board in the ceiling assembly frame. With a sharp object, you can change the COMPRESSOR DELAY function

control. As illustrated below. You must apply the above procedures to only one of two units. The unit applied this

function starts approximately 3 seconds later than the normal unit does, so the simultaneous start of the units is

impossible in general.

COMPRESSOR DELAY FUNCTION

CHOOSING LOCATION FOR THE AIR CONDITIONING

A. For One Unit: The air conditioner should be mounted slightly forward of center (front to rear) and

centered from side to side.

B. For Two Unit: Install one air conditioner 1/3 and the other air conditioner 2/3’s from front of RV and

centered from side to side with referring to compressor delay function. You must apply the

compressor

delay function (3SEC) to only one of two units.

C.If you have more than two air conditioning system, install the units as follow order with referring to

compressor delay function.

3SEC-NO-3SEC..... or NO-3SEC-NO......

NOTE

•The Distance among the units should be more than 8.2 feet to avoid the simultaneous operating by one

remote hand set signal.

CAUTION

OWNER’S GUIDE - 8

Replacing Batteries

•Do not fit used batteries or batteries of different type. Such use may cause the unit to malfunction.

•Changing batteries should be done after turning off the unit.

•The average battery life during normal use is one year approximately.

•When the air conditioner does not operate normally after replacing the batteries, remove the batteries,

refit them and repress the RST button after 5 seconds.

NOTE

Signal Receiving

Use the remote control where its signal can reach the receiver of the air conditioner.

- You can hear the beeping sound from the unit in the remote control operation, which indicates that

the signal is received.

Remove the cover of the battery compartment at the back of the remote control by sliding it out.

Remove the old batteries and insert the new batteries. The remote control uses two alkaline batteries.

(1.5V, LR03x2)

Press the RST button with a sharp object to reset the remote control before closing the cover of the battery

compartment.

•The air conditioner will not operate if curtains, doors or other materials block the signals from the remote control to

the unit.

•If the infrared signal receiver on the unit is exposed to direct sunlight, the air conditioner may not work properly.

Draw the curtains to avoid direct sunlight.

•Avoid spilling liquid onto the remote control or dropping it. This can cause deformation, dislocation and malfunction.

•A mounting bracket for the remote control is supplied with the unit. Install the mounting bracket on the wall by

using two sharp point wood screws and/or double sided tape attached on the back of the bracket. This prevents

the remote control from being lost.

PROCEDURE

OWNER’S GUIDE -10

Moving parts can cause personal injury. Be careful when test-running the unit.

Do not operate the unit with exterior cover removed.

WARNING

BEFORE INSTALLATION

ENERGY SAVING TIPS

Select the temperature setting that suits your comfort needs and leave it at that chosen setting.

Keep the unit’s air filters clean. (See the Normal Maintenance Procedures section of this manual on page 19.)

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

- 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

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.

Telescoping Divider # Range

71DC6A3006 (supplied) 3.25”~ 4.25”

71DC6A3005 2.0”~ 2.75”

71DC6A3007 5.0”~ 6.0”

Provided with the ceiling assembly frame is a tele-

scoping divider assembly which is used to sepa-

rate the warm return air from the cold supply air.

The telescoping divider size is determined by mea-

suring the ceiling cavity depth. (the measurement

from the ceiling to the roof)

The ceiling assembly frame must be installed over

the roof opening. The ceiling assembly frame bolts

to the bottom of the roof top unit. Compression of

the framed ceiling cavity between the roof top

unit and the ceiling assembly frame is what holds

both components in place.
