12.1 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 seawater
temperature exceeds 13°C.
- In winter, you can programme the dehumidifier function on the air conditioning 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 relay boxes.
- Seawater is drained via a through-hull fitting equipped with a valve, located above the waterline. Each compressor has its own through-hull drainage 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 approximately 3 minutes.
If the seawater pump is deprimed (eg. in case of running aground), carry out the following procedure:
- Disconnect the discharge hose from the seawater pump by loosening the 2 stainless steel collars;
- Blow air through the pipe using a compressor;
- Re-connect the discharge hose with 2 stainless steel collars.
When the air conditioning is running:
- Switch the air-conditioning circuit-breakers ON.
- Select the temperature of each compressor using the control units.
