• When the roof thickness is greater than 100mm, additional air duct is required for connection.

1.3. Introduction of Air Conditioner
The design and installation of this machine is suitable for RV to improve its internal temperature and provide a comfortable environment. It can cool the RV when it’s hot and warm up the RV when it’s cold. Its temperature can be adjusted in the two environments.
1.4. User Guide
The performance of air conditioner is related to the heating condition of insulation box of RV itself. Users can take some preventive measures to reduce heat entry, so as to improve the refrigeration performance of air conditioning equipment.
When outdoor temperature is high, the following methods can be adopted to reduce the heat entry of RV and improve work efficiency:

• Park the RV in acool place.
• Strengthen thermal insulation of the compartment, remove or block the opening in the vehicle, and block the window with shade curtains (shutters or hanging curtains).
• Close doors and windows or avoid frequent opening and closing of them.
• Avoid using heating devices inside the vehicle.

Turn on the air conditioner in advance to achieve better effect.
When indoor or outdoor temperature is high, setting the air conditioner in cooling mode and turning on high wind speed will bring the performance of air conditioner into full play.
Note: during the use of this product, due to the great change of air temperature in the vehicle, when the temperature drops rapidly, part of condensate will adhere to the surface of objects near the air outlet, which is a normal phenomenon. After the air conditioner works normally for a certain period, it will be automatically dried and detached from the surface of objects. Therefore, when the air conditioner works, please close the doors and windows as much as possible to reduce the coagulation of water vapor on the surface of objects inside the vehicle.
The manufacturer will not be responsible for any damage arising from condensation on the ceiling or the surface of other objects caused by the condensate of this product.

• Size of RV
• Window area of RV (the larger the area, the more heated)
• Thickness and thermal insulation performance of insulating materials in compartment plate and roof
• Geographical location where the RV is used by users

2.2.2. Selection of Installation Position:

• This product should be installed on the existing roof vent.
  There is usually a 362x362mm + 3mm opening on the roof after the vent is removed.

• When there is no vent on the roof or this product needs to be installed in other positions, it is recommended to take the following measures:

1. For the installation of a single air conditioner, the air conditioner should be installed at a position slightly ahead of the center point (as viewed from the head of the vehicle) and at the center point of left and right ends, as shown in the following figure:
2. For the installation of two air conditioners, the air conditioners should be installed at 1/3 and 2/3 positions away from the front end of RV respectively, and at the center point of left and right ends, as shown in the following figure:

• It’s best to install this product horizontally (subject to the standard that the RV stops on a horizontal surface) witha maximum gradient of not exceeding 15°.
• After the installation position is determined, it is required to check whether there are obstacles in the installation area, and the distance between the back of vehicle body and other roof equipment should be at least 457 mm.
• When the RV is moving, the top must be able to support heavy objects weighing 60kg. Generally, the static load design of 100kg can meet this requirement.
• Check whether there are obstacles (i.e., door openings, partition frames, curtains, ceiling fixtures, etc.) that hinder the installation of inner panel of the air conditioner.
• The overall dimensions of each outdoor unit and panel are as follows:

2.3. Preparation for Installation
2.3.1. Disassembly of Roof Vent

• Unscrew the screws and remove the vent;

• Seal all screw holes and joints at the roof washer, and use excellent all-weather sealant to ensure the sealing effect.

2.3.2. New Roof Opening (not the Installation of Vent)

• Cut a 362x362mm+3mm opening on the roof of RV, which must be located between the roof reinforcements and must pass through the roof and ceiling of the RV;

There may be wiring between the roof and ceiling.
The 220V AC power supply must be cut off before installation. Failure to follow this instruction may result in electric shock and further cause death and personal injury.

• Mark a 362x362mm+3mm square on the roof and cut an opening carefully;
• Cut a matching hole on the ceiling based on the roof opening, as shown in the following figure. (There should be no obstacle within a minimum distance of 457mm at the back of vehicle body.)

2.3.3. Notes for Hole Opening

• If the opening exceeds 365x365mm, gaskets must be installed.
• If the opening exceeds 358x358mm, the opening must be enlarged.

2.3.4. Wiring Requirements

• The wiring method must comply with all national wiring regulations.

• Fuse or circuit breaker should be installed and it should be well grounded. Lead out a 2.5m’ copper cable from the circuit breaker to the front position of the roof opening:
  The power line must be located on a separate 20A delay-action circuit breaker:

• Ensure that the wire extends into the roof opening by at least 380mm, which can facilitate the installation of air conditioning equipment;

• After the ventilator is removed, if the size of wire left is appropriate and the fuse specification is also appropriate, it can be used;

The wire entering the opening should be protected to avoid damage.
2.3.5. Opening Treatment

• The opening must be adequately supported, and the roof interlayer should be filled with insulating materials. To prevent resonance caused by air in the upper interlayer, it is required to seal the periphery with battens with a thickness of 20mm or more, and provide a wire inlet for the power line, as shown in the following figure:
• The 362 x 362mm+3mm roof opening is an integral part of the return air duct and must be polished according to industry standards.

The installation personnel of air conditioning equipment shall be responsible for ensuring structural integrity of the roof of RV. Do not create a low-lying place where water will accumulate on the roof. Otherwise, stagnant water around may seep into the vehicle, causing damage to this product and RV.
2.3.6. Placement of Air Conditioner on the Roof
The heaviest outdoor unit of this product weighs about 45Kg. To prevent damage to the air conditioning equip-ment, please lift this product to the roof with a crane.
