Thickness and thermal insulation performance of insulating materials of the RV.

Selection of Installation Position:
This product shall be installed in the place of an existing roof vent or in an area which has been constructed to carry the weight of an air conditioner.

There must be an opening with the size of 14 ¼” x 14 ¼” ±¼” (362 x 362mm ±3mm).

When there is no existing opening on the roof or this air conditioner needs to be installed in other positions, it is recommended to take the following measures:

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 in the middle sideways. Refer to following illustration
For the installation of two air conditioners, the air conditioners should be installed at ⅓ and ⅔ positions away from the front end of RV respectively, and at the middle sideways. Refer to following illustration:
The rooftop unit shall be installed leveled (maximum inclination permitted: 15 degrees).
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 18″ (457mm).
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 rooftop unit and the air distribution box are as following:

Preparation for Installation

Installing in an Existing Opening

Unscrew and remove the roof vent.
Remove all caulking compound around the opening.
If the opening exceeds 14 ¾” x 14 ¾” (375 x 375mm), it will be necessary to resize the opening to 14¼” x 14¼” (±½”) [362 x 362mm(±12.7mm)]. If the opening is less than 13 ¾” x 13 ¾” (349 x 349mm), it must be enlarged.

New Roof Opening
Cut a 14¼” x 14¼” + ⅛” (362 x 362mm + 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

WARNING
There might be existing high and low voltage wiring in the ceiling construction. Shut off the mains battery switch and disconnect the RV from the shore power outlet. Failure to follow this instruction may result in electric shock and further cause death and personal injury

Mark a 14¼” x 14¼” ± ⅛” (362 x 362mm ± 3mm) square on the roof and cut the square hole 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 18″ (457mm) to the back of vehicle body).

Notes for Hole Opening

If the opening exceeds 14⅜” x 14⅜” (365x365mm), gaskets must be installed.
If the opening exceeds 14⅛” x 14⅛” (358x358mm), the opening must be enlarged.

Wiring Requirements

The wiring method must comply with all national wiring regulations.
Ensure that the wire extends into the roof opening by at least 14 15⁄16”(380mm), which can facilitate the installation of air conditioning equipment;
In case a vent fan has been removed, stow away any existing wiring in a safe manner.
Ensure sheathing of wire is not getting damages by any sharp corners/edges/penetrations.

Reinforcement at cutout

The opening must be adequately supported, and the roof inner structure should be filled with insulating materials. To prevent resonance caused by air in the roof structure, it is required to seal the periphery with battens with a thickness of¾” (20mm) or more, and provide a wire inlet for the power line as shown in the following figure:
The 14¼” x 14¼” ± ⅛” (362 x 362mm ± 3mm) roof opening is an integral part of the return air duct and must be polished according to industry standards.

NOTE
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
