3.4- SEA WATER CIRCUIT
Some rules are given at chapter 2.6. We can resume the following:
The circuit should always rise from water intake to the unit heat exchanger. After that the circuit can rise again or drop to
the discharge port. It is absolutely important to prevent that the circuit rises and drops making siphons which will prevent
air to be drained, causing an air lock. The discharge side of the circuit should be made so that the water discharge does-
n't cause excessive noise both for this yacht and for its neighbours.
3.5 - ELECTRICAL CONNECTION
The pumps have a single phase motor, which needs a
three wires connection: for neutral phase and ground.
Always check that the pump voltage meets mains supply
available on board. Connect the pump as shown at chap-
ter 4. At first run check the pump electrical drawn is within
the plate value. In case it exceeds, install a calibration
valve on pump outlet and reduce the flow until the electri-
cal draw drops within the limit.
3.6 - SELF PRIMING PUMP
If installation specifications given at 3.2 cannot be met, a
self priming pump should be installed. For its installation,
follow the same specifications given for a centrifugal pump.
Before running the pump, it is necessary to fill the pump
tank to make it self priming.
3.7- WATER CALIBRATION VALVE
When more than one air-conditioner is installed at different
distances, it might be necessary the use of one or more
calibrating valves to compensate the different runs of water
lines to the different units. The calibrating valve must be
also needed in case of excessive water flow passing
through the unit. Follow instruction supplied with the cali-
bration valve.
