4- COMMISSIONING

4.2 Start up

Give supply to the main control box.Turn the "Mode" switch to the "Cool" or "Heat" position. Check that both pumps for boats have an even flow. As the compressor runs, the fresh water temperature will begin tocool down (if the unit is in "Cool" mode) or to heat up (if the unit is in "Heat" mode). As the fresh water temperature is approaching the set point ("Cool" mode = +12° C, "Heat" mode = +40° C) the thermostat will stop the compressor. The speed at which the water cools down depends from several fac-tors, as the number and capacity of fan coil connected, the fan coil speed, the room temperature, etc….; therefore this value is not a valuable parameter.

4.3- Sea water circuit

Check that the sea-water intake is fully open and that the flow is even.
