Choosing Proper Location for the Air Conditioner

IMPORTANT: The roof must be designed to support the weight of the rooftop unit and the weight of 2 installers standing on the roof. There are two ways of installing the rooftop air conditioner:

● Using the existing roof vent opening in the vehicle roof.

● Making a new opening. In this case the opening should be reinforced by an appropriate frame as required.

Existing Roof Vent Opening

The air conditioner is designed to fit over an existing 14” roof vent opening.

New Opening

When no roof vent is available or another location is desired, the following is recommended:

● For one unit installation - the air conditioner should be mounted slightly forward of center (front to back) and centered from side to side.

● For two unit installations, install one air conditioner one third from the front of the RV and the other air conditioner two thirds from the front of the RV, aligned in the center.

It is preferred that the air conditioner be installed on a relatively flat and horizontal roof section measured when

Page 7

Before Installing

the RV is parked on a level surface. NOTE: A 15° slant to either side or front to back is acceptable for all units. If the roof exceeds 15° please use an exterior leveling shim to make air conditioner level.

After the Location has been Selected:

● Check for obstructions in the area where the air conditioner will be installed.

Roof Preparation

Opening Requirements - Before preparing the ceiling opening, decide on the type of system options. Read all of the following instructions before beginning the installation.

WARNING

Fire/Electric Shock Hazard

● Make sure there are no obstacles inside the RV roof, floor and walls, such as wires and pipes.

● Shut off the gas supply and disconnect the 115VAC power from the RV before drilling or cutting into the RV. Failure to obey these warnings could result in death or serious injury.

Roof Thickness

The installation of air conditioner suits for roof thickness from 3.5” (90mm) to 6” (152mm). For other thickness, please contact Furrion or Furrion authorized service agent.

Installing in an Existing Opening

1. Unscrew and remove the roof vent.

2. Remove all caulking compound around the opening.

3. If the opening exceeds 14⁄” x 14⁄” (+⁄”), it will be necessary to resize the opening to 14⁄” x 14⁄” (+⁄”). If the opening is less than 14⁄” x 14⁄” (+⁄”), it must be enlarged.
