Installation of this appliance requires a qualified RV technician.

The approximate completion time for installation is 1 hour.

It is recommended that two people install this product.

Proper installation is the responsibility of the installer.

Product failure due to improper installation is not covered under the Warranty.

You MUST use all supplied parts and use proper installation procedures as described in these instructions when installing this air conditioner.

Be cautious of sharp edges as they may cause injury. When lifting the air conditioner, use 2 people to lift.

Electrical wiring may be present between roof and ceiling. Be sure that power is disconnected at the mains and battery. Be sure that the gas supply is shut off. Failure to do so may result in injury or death.

Air conditioners covered in this manual are designed for installation on an RV’s roof.

Installation of this air conditioner must be in accordance with NFPA 1192 and NFPA 70.

For proper installation, there must be a 14 3/8″x14 3/8″ (+/-1/4″) square opening in the roof and ceiling of the RV.

There must be 2-6″ of space between the RV ceiling and the roof to accommodate our air division baffle.

If a roof vent opening isn’t available, the unit is to be installed centered side-to-side on the RV roof.

The unit is to be installed on a section of roof which is level with respect to the RV roof if parked on a flat, level surface.

The roof at the point of install can have a maximum tilt angle of 15° toward the front or rear of the RV.

1. Unscrew and remove roof vent from RV.

2. Seal all holes and seams with a weather resistant sealant.

3. Measure the width and length of the vent opening. If the opening doesn’t comply with the requirements from section A, it must be resized.

If a preexisting opening will not be used, a new opening will be cut through both the roof and ceiling of the RV.

1. This opening MUST be between structural roof members.

2. Do NOT cut structural roof members to create opening for this air conditioner. Doing so may cause damage to RV and air conditioner.

3. Do NOT create a low spot on the RV roof. Water can pool and may leak through the opening.

The square opening must be boxed with framing at least 3/4″ thick to withstand the load from the compression bolts.

Yes, be sure to provide an access hole for RV wiring toward the front of the 14 3/8″ x 14 3/8″ opening.

The roof and RV structure at the point of install must be strong enough to support the air conditioner without any deflection. If in doubt, please contact your RV manufacturer. Deflection will allow water to pool at the air conditioner’s gasket, and may cause a leak.

These models require a 115V, 60-Hz protected with either a 15-amp or 20-amp time-delay fuse or circuit breaker. Use a minimum of sheathed, 12 AWG copper wire with ground. Be sure that 16″ of supply wire is passed through the framing. This ensures enough wire is available for an easy connection in the junction box.

When lifting the unit to the RV roof, ensure proper lifting methods and controls are used. Failure to do so can result in injury.

First, remove the unit from its packaging and dispose of the packaging.

Do not slide the unit on its mounting gasket, as damage to the gasket can cause a leak. Using two people, lift the unit and place it over the prepared opening. The front of the unit must face the RV’s direction of travel. Damage to the condenser fan and coil will occur if this instruction is not followed.

Failure to securely install the unit to the RV before moving the RV may result in personal injury or death.

Do not operate the unit or recreational vehicle until the unit is fully secured on roof.

Bring the ceiling assembly with all provided mounting hardware into the RV. If you are using an indoor assembly, all work on the exterior of the RV is now complete.

You will need to install accessory RGRFG1A foam gasket to prevent the inlet and outlet airflows from mixing. Tilt your unit up and peel the adhesive release liner from the back of the RGRFG1A foam gasket. Adhere the gasket to the bottom of the unit’s base pan between the air inlet and outlet openings.
