1. For one unit installation: The air conditioner / heat pump should be mounted slightly forward of center (front to back) and centered from side to side. See FIG. 1. FIGURE 1 2. For two unit installation: Install one air conditioner / heat pump 1/3 distance and the other air conditioner / heat pump 2/3's from front of RV and centered from side to side. See FIG. 2.
front-to-back is acceptable. C. POST LOCATION SELECTION: 1. Check for obstructions in the area where air conditioner / heat pump will be installed. A minimum clearance of 18” is required for the rear section of the air conditioner / heat pump to any other roof mounted object. 2. The roof must be capable of supporting 100 lbs while the RV is in motion. Normally, a 200 lb. static load design will meet this requirement. 3. ROOF PREPARATION A. EXISTING ROOF VENT REMOVAL: 1. Unscrew and remove the roof vent.
C. OPENING PREPARATION: 1. If the opening exceeds 14-3/8" x 14-3/8", it will be necessary to install spacers. 2. If the opening is less than 14-1/8" x 14-1/8", it must be enlarged. 3. Route a 12/3 Romex type supply line from the circuit breaker box to the Front of the roof opening. a. The power supply must be on a separate 20 amp Time Delay Fuse or HACR Circuit Breaker. b. Wiring must comply with all National, State and Local wiring codes. c.
5. The 14-1/4" x 14-1/4"(±1/8) roof opening is part of the return air duct and must be finished in accordance with NFPA standard 501C, Standard for Recreational Vehicles, Section 2-7. It is the responsibility of the installer of this system to ensure structural integrity of the RV roof. Never create a low spot on the roof where water will collect.

4. The ACRG12 has a 6 pin, 4 pin, 3 pin & 2 pin connectors extending from the front of the relay kit. These connectors mate with the air conditioner / heat pump. When making this connection, verify that the plugs are properly aligned and have snapped together securely. 5. Provided with the ACRG12, is a divider plate which is used to separate the warm return air from the cold supply air. If the roof thickness is greater than 2.5”, you MUST use the additional divider provided.
SUPPLY DUCTING AND REGISTERS A. Ducting 1. The field fabricated supply ducting must attach to both sides of the ACRG12. A minimum of two ducts are required, with one duct attached to each side of the plenum. 2. Each duct must have a minimum height of 1-1/2". Maximum height cannot exceed 4”. Total free area inside each duct must be no less than 10 square inches. NOTE: To decrease restriction and increase airflow, the ducting should make as few bends and turns as possible.

Make any adjustments required to relieve pinched or stressed wiring. 2. Remove ¼” insulation from the 4 wires. Use a small Flat-head screw driver to loosen the wire terminal screws. Push each corresponding wire into the proper terminal hole and tighten each screw.
CONNECTING 115VAC WIRING 1. WARNING - SHOCK HAZARD: To prevent the possibility of severe personal injury or equipment damage due to electrical shock, always be sure the electrical power is disconnected or off before beginning installation. 2. Route the 115 VAC supply wiring previously routed into the frame of the roof opening, through the strain relief of the electrical box and into the high voltage wiring area.
