Understand the Installation Requirements for RV Rooftop SystemsUpdated 3 days ago

This article explains the installation requirements for RV rooftop systems. 

Select the Installation Position

This product is intended to be installed on an existing roof vent. Typically, a 14-1/4" x 14-1/4" ± 1/8" opening will be available on the roof after the vent is removed. 

If there is no vent on the roof, or if this product needs to be installed in another position, it is recommended to follow these guidelines:

• When installing a single air conditioner, it should be positioned slightly ahead of the center point (as viewed from the front of the vehicle) and centered between the left and right sides. 
• When installing two air conditioners, the units should be positioned at the 1/3 and 2/3 points from the front end of the RV. The units should also be centered between the left and right sides. 

Factors for Installation

When determining the cooling requirements, take the following factors into consideration:

• Size of the RV: Larger RVs may require more cooling capacity. 
• Window Area: A larger window area can result in increased heat inside the RV. 
• Thickness and Thermal Insulation: Consider the thickness and thermal insulation properties of the compartment walls and roof. 
• Geographical Location: The climate and conditions of the location where the RV is used can impact cooling requirements. 

Installation Requirements

• The system can either be installed during the production phase of the RV or after its completion. 
• For optimal performance, install the system horizontally on the top of the RV (assuming the RV is parked on level surface) with a maximum allowable gradient of more than 15°. 
• Once the installation position is determined, check for any obstacles in the designated area. Ensure that there is a minimum distance of 1.5 feet (457 mm) between the back of the vehicle body and any other roof equipment. 
• The minimum spacing between rafters and joists on the roof structure should be 15-3/4 inches (400 mm)
• The roof thickness of the RV must be at least 1 inch (25 mm) and no more than 4 inches (102 mm). If the roof thickness exceeds 4 inches, an additional air duct connection is required. 
• When the RV is in motion, the roof must be capable of supporting a load of 135 lbs. Typically, a static load design of 220 lbs is sufficient to meet this requirement. 
• Verify that there are no obstacles that would interfere with the installation of the inner panel of the air conditioner, such as door openings, partition frames, curtains, or ceiling fixtures.
