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

1. Using the existing roof vent opening in the vehicle roof.
2. 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 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

1. Check for obstructions in the area where the air conditioner will be installed.
2. Check the inside of the RV for return air kit obstructions. (i.e. door openings, room dividers, curtains, ceiling fixtures, etc.) Allow 6” (152mm) space from the opening to account for any potential return air kit obstructions.

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 141/4″ x 141/4″ (+1/2″), it will be necessary to resize the opening to 141/4″ x 141/4″ (+1/2″). If the opening is less than 141/4” x 141/4″ (+1/2″), it must be enlarged.

Making a New Opening

If a roof vent opening will not be used, a 141/4″ x 141/4″ (+1/2″) (362mm x 362mm) opening must be cut through the roof and ceiling of the RV. This opening must be located between the roof reinforcing members. The 141/4″ x 141/4″ (+1/2″) opening is part of the return air system of the air conditioner and must be finished in accordance with NFPA Standard 501C Section 2.7.2.

1. Mark a 141/4″ x 141/4″ (+1/2″) square on the roof and carefully cut an opening.
2. Using the roof opening as a guide, cut a matching hole in the ceiling.
   • NOTE: Maintain structural integrity. Otherwise damage to product and/or RV could occur. Always observe the following guidelines while structuring the opening.
3. The opening created must be framed to provide adequate support and prevent air from being drawn from the roof cavity.
4. Lumber 3/4″ or more in thickness must be used. Remember to provide an entrance hole for power supplies, wall thermostat and furnace wiring for connections. Leave 15″ (381mm) minimum at the front of the opening.

Air Distribution Duct Sizing and Design

The installer of this system must design the air distribution system for their particular application.

NOTE: Make sure ductwork will NOT bend or collapse during and after installation, and that it is correctly insulated and sealed. Otherwise, damage to roof structure and ceiling could occur.

CLEANING AND MAINTENANCE

A blocked filter will impair the cooling and heating performance of the unit significantly. The filter must be cleaned periodically to ensure that it does not become clogged with dust and other particles. The state of the filter can be ascertained from its appearance. If it appears dirty or clogged then it should be cleaned.

WARNING

Airborne particles can pose a health risk, particularly to young children and the elderly. Ensure that filters are cleaned in a safe and well-ventilated area.

To Clean the Filter

The filter should be cleaned every four weeks or more when in use. Prolonged use, higher concentrations of airborne particles and various other factors may result in the filters needing to be cleaned more often.

1. Remove the filters by pushing the tabs to release. (Fig. 18)
2. The filter can be washed with warm soapy water. Care must be taken to avoid ripping the fabric.
3. Replace the filters, decoration plate and control knobs by reversing the above process.
   • NOTE: The filter must be completely dry before reinstallation.

To Replace the Filter

Filter changes should be carried out depending on the amount of use, it is recommended to change at least every 12 months. Never operate the air conditioning system without a filter, since this can decrease performance and indoor air quality. Replacement return air filters can be ordered directly from Furrion.
