If your recreational vehicle doesn't have an air conditioner, trips during warmer months can be uncomfortable. The good news is that most RVs today come prepared to have an air conditioning unit installed through a ceiling vent, so you won't need to cut any holes into your ceiling. These units usually run on 120-volt AC power, so they need to connect to a generator and not the vehicle's battery.
Instructions
1. Remove the vent on the roof/ceiling of the RV; it could have bolts that require a wrench or screws that require a screwdriver. Make sure the air conditioner you get is the correct size to fit into the hole created by removing the vent. Remove all trim surrounding the vent as well.
2. Install the roof portion--the main unit--of the air conditioner onto the roof of the RV. This should fit into the vent hole, and there should be mounting holes on the roof for you to line up with the mounting holes on the AC unit.
3. Connect the mounting frame to the unit, which should connect on the ceiling side. This should include a gasket that you will mount in between the unit and frame. Then tighten everything with the mounting bolts. Don't use any aftermarket sealant because the unit needs to be flexible with the ceiling.
4. Wire the air conditioner to your RV's generator. This can be as simple as using a built-in electrical connector in the vehicle, but you might need to solder wires together as the unit's instructions specify. Do not attempt to connect individual if you have no experience doing so.
5. Turn on the air conditioner to test it. The air conditioner unit should already be charged, so it should operate as long as it is properly wired.
