OWNER’S GUIDE - 2
A FEW WORDS ABOUT YOUR NEW
AIR CONDITIONING UNIT
Thank you for choosing the Air V, Carrier Recreational Vehicle Air Conditioner, for your comfort needs.
You can feel confident in your selection because the same pride in craftsmanship and engineering knowledge
that goes into Carrier equipment to cool the Astrodome in Texas, the famous Sistine Chapel in Rome,
the Washington DC Halls of Congress and thousands of other installations worldwide has gone
into the construction of your unit.
In addition to cooling the room, your Carrier heat pump unit will also heat, filter and dehumidify the room’s air.
In heating mode, the heat pump will shut down at conditions which would cause outdoor coil freeze up, generally
near freezing temperatures.
The Air V air conditioners quietly give you maximum cooling and heating comfort.
Now you can “Feel Carrier’s Comfort”!
This manual is designed to help you with all the information you need for installing, operating and maintaining your
new unit. In addition, this contains many comforts and technological features your unit offers. Take a few minutes to
discover how to get the most in cooling or heating comfort and economic operation from your new Air V.
Please keep this manual handy for future reference, and be sure to send in your warranty card.
You can also contact us by the internet web site, www.airv.com .

NOTE
If you want to stop the emergency operation, push the EMERGENCY button again or operate
the remote control.
* TEST MODE: Installer can operate the unit anytime regardless of temperature by pushing Emergency Button
(COOL or HEAT) more than 5 seconds continuously after installing the unit. (This function is only used by
servicemen to test the unit operation.)
* Refrigerant Compressor Time Delay : The air conditioning system is equipped with a time delay on the

compartment.
NOTE
• 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.
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.
CAUTION
• 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.

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

2 Each
inside each duct must be no less than 10 square inches.
NOTE
To decrease restriction and increase air flow, the ducting should make as few bends and turns as possible. When
corners or turns are required, we recommended that you radius the corners to keep air flow at a maximum.
Ten (10) square inches of free area per duct is the minimum requirement, larger ducting will improve air flow
and system performance.
3 When ducting secures to the ceiling assembly frame, maximum width is 8 inches and maximum
height is 3 1/2”.
4 All field fabricated cold air supply ducting must be insulated and must have a vapor barrier.

COMPLETING THE INSTALLATION
To complete the installation and system checkout requirements, the following steps must be performed.
A. Check the room air thermistor position. Make sure the room air thermistor is routed through the holding guide,
and is not touching any metal surface.
B. Refer to p.18, and remove the air filters by pulling them.
C. Secure the grille to the panel with 4 screws. At this time, take care of the position of the
room air thermistor which must be mated with the thermistor hole of the grille.
D. Reinstall the air filters.
E. Turn on the power supply to the roof top air conditioner.
