3 Installation Instructions

3.1 Choosing Proper Location For Unit

This unit is specifically designed for installation on the roof of an Marine rooftop Air conditioner. When determining your cooling requirements, the following should be considered:

• Size of Marine rooftop Air conditioner;
• Window area (increases heat gain);
• Amount of insulation in walls and roof;
• Geographical location where the Marine rooftop Air conditioner will be used;
• Personal comfort level required.

Normal locations-The unit is designed to fit over an existing roof vent opening. Other locations-When no roof vent is available or another location is desired, the following is recommended:

1. For one unit installation: The unit should be mounted slightly forward of center (front to back) and centered from side to side.
2. For two unit installations: Install one unit 1/3 and one unit 2/3's from front of Marine rooftop Air conditioner and centered from side to side. It is preferred that the unit be installed on a relatively flat and level roof section measured with the Marine rooftop Air conditioner parked on a level surface. The maximum inclination Angle is 8°.

3. Maintain structural integrity. Otherwise damage to product and/or Marine rooftop Air conditioner could occur. The roof must be designed to support 130 pounds when Marine rooftop Air conditioner is in motion. Normally a 200 lb. static load design will meet this requirement.

4. Check inside the Marine rooftop Air conditioner for air distribution box (hereinafter referred to as "ADB") obstructions (i.e. door openings, room dividers, curtains, ceiling fixtures, etc.).

CAUTION

NEVER create a low spot on Marine rooftop Air conditioner roof. Otherwise, water will pool and could cause a leak.

Using the roof opening as a guide, cut the matching hole in the ceiling. The opening created must be framed to provide adequate support and prevent air from being drawn from the roof cavity. Framing stock 3/4" or more in thickness must be used. Remember to provide an entrance hole for power supplies at the front of the opening.

3.2.2 Using an Existing Roof Opening

1. Unscrew and remove the roof vent.
2. Remove all caulking compound around opening.
3. Seal all screw holes and seams where the roof gasket will be located. Use a good grade of all weather sealant.

3.3 Wiring Requirements

Route a copper, with ground, 120 Vac supply wire from the time delay fuse or circuit breaker box to the roof opening. Use a listed/certified non metallic - sheathed single strand cable.

If vent fan was removed, the existing wire may be used provided it is of proper type, size, location, and correctly fused.

1. This supply wire must be located in the front portion of the roof opening.
2. The power MUST be on an appropriately sized separate time delay fuse or circuit breaker. See "2.1".
3. Make sure that at least 15" of supply wire extends into the roof opening. This ensures an easy connection at the junction box.
4. Protect the wire where it passes into the opening with approved method.

3.4 Placing Unit On Roof

1. Remove the unit from the carton and discard carton.
2. LIFTING HAZARD. Use proper lifting technique and control when lifting product. Failure to obey this caution could result in injury. Place unit on the roof.
