11.1 AIR CONDITIONING
General points
- The air-conditioning is powered by alternating current.
- The air-conditioning cools the air temperature inside the boat (only when the boat is floating
in water).
- The cooling circuit consists of one or more compressors that operate independently. A
compressor is called "reversible" because it can heat the boat if the sea water temperature
exceeds 13°C.
- In winter, you can programme the dehumidifier function on the airconditioning controls.
- The refrigeration compressors are made by one or two seawater pumps. These pumps are
run on AC voltage and are master controlled by one or two can relays.
- Sea water is evacuated through a through-hull fitting equipped with a valve, located above
the waterline. Each compressor has its own through-hull evacuation fitting. It is advisable to
check the flow of water visually once the air conditioning starts running.
Operation
Before starting the engine::
- Open the raw water intake valves and evacuation valves ;
- Make sure that the control panel is in the STOP position ;
- Use the switch on the chart table to select the power source (shore power or generator).
- If using shore power: plug into the shore power socket ;
- If using the generator: before turning on the air conditioning, leave the generator
running for about 3 minutes.
