Self-Contained Marine Air Conditioning
Installation Instructions

Choose a location that is dry and accessible for service. The air access should be from the return air source only and should not be contaminated by air from the engine room, bilge, heads, holding tanks, etc. Placement of the unit should be adjacent to a low return air access from the area to be conditioned. Never install the unit in the engine room. (Split systems available for compressor/condenser installation in the engine room.)

This self-contained unit is furnished with a complete installation kit as shown in the diagram. Secure the unit on a horizontal surface sufficient for the weight of the unit and the rocking motion of the boat. Condensate drains must be routed downward without any kinks or restrictions to a sump or overboard discharge, and should be securely fastened as should all components of the system. All equipment should be properly grounded.

Digital control is standard. Analog also available.

Note: 77°F (25°C) is standard room temperature.
