Page 7: Installation Requirements
Dometic self-contained air conditioners do NOT meet Federal requirements for ignition protection. NEVER install the Dometic air conditioner in an engine room, the bilge, or any areas where it may introduce deadly or noxious vapors into the boat's living space. NEVER install the unit in any room or compartment that contains an internal combustion engine, fuel tanks, LPG/CPG cylinders, regulators, valves, or fuel line fittings.

However, the breaker must be sized for both the water pump and the Dometic unit. A separate breaker is required for the water pump if multiple Dometic units are installed.

YSTEM Proper water flow is absolutely critical to the operation of the Dometic air conditioner. If the pipe is too small, back pressure is created, causing a drop in water flow, even if the pump is correctly sized. If the piping is too large, the slow velocity of the water may cause silt build-up and barnacle growth inside the piping, eventually restricting water flow.
Page 10: Duct Work Guidelines
The return air grille must have sufficient open air to permit adequate air to the indoor coil. The Dometic air conditioner has a factory provided filter located in front of the air coil. If a return air filter grille is used, it is recommended that the filter on the unit be removed.
