Installation Area
-
The 579 is designed to be installed either on an inside roof or on top of an outside roof of an RV. It also must be connected to the air ducts of an RV to properly circulate air during usage. The surface must be flat and level, with a slant that must not exceed 15 degrees, and it must be capable of supporting up to 130 pounds when the RV is moving. Measure the surface's maximum angle with a 360-degree protractor to ensure that it meets the requirements necessary for proper installation to your RV, and check the specifications in your RV's owner's manual to make sure the surface can support at least 130 pounds.
Installation Preparation
-
Carefully remove any obstructions near the surface where the 579 is to be installed. Check the duct specifications in your RV's owner's manual, such as size and air pressure, to ensure they match up with those of 579 before installation. If you are installing the unit on your RV's outside roof, you must cut out the specified opening where it is to be placed before you can begin installing it to the duct. You also must support the unit with the appropriate lengths of lumber after you've placed it inside the hole.

Installation Wiring
-
Connect the 12 AWG copper wire and 120-VAC supply lines to the RV's fuse or circuit breaker and run them up to the 579 afterward; you must connect these wires to the RV's appropriate box first to provide them with the power they'll need to run the unit. Check the lengths of the wires before you install them; the recommended length that runs through the opening for this unit is 15 inches. Run more wire through the opening, if necessary, before you install the wires to the unit.
Comfort Control Center
-
This device must be properly installed to ensure functionality of the 579; the CCC controls the temperature provided to the interior of the RV during operation. Install the CCC inside the RV at least 54 inches above the ground and ensure it's connected to an area not close to doors or windows, in addition to being far removed from high-heat sources, such as lamps and appliances. Connect its cable with the proper connectors by running a 12-VDC supply wire from the RV's converter or battery to the unit on the roof. Ensure that at least 15 inches of the wire sticks out of the roof before installing the cable to the unit.
