AIR CONDITIONING
GENERAL POINTS:
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 10°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
powered by 220V or 110V and are guided by one or two relay boxes.
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.
- 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.
The air conditioning is running:
- Switch the circuit breakers 220V ,from the air conditioning,ON.
- Select the temperature of each compressor using the control units.
WARNING
- Refer to the apparatus instructions for use and maintenance.
- Never start the generator when the climate function is already on.
- Always turn off the air conditioning before turning off the generator.
- Regularly check and clean the sea water filter placed on the sea water intake
through-hull fitting.
- Clean the air filter (located in the compressor) regularly for maximum
performance of the installation.
