4 SEA WATER CIRCUIT
4.1 - SEA WATER PUMP
The sea water pump must be of the correct size for the Compact unit
.
Most installations require a centrifugal pump, and close attention to
the installation requirements must be made to ensure trouble-free
operation.
Centrifugal pumps are not self-priming and MUST be mounted with the
discharge below the waterline, with a rising hose run through the strainer
and on to the pump, and with a scoop intake strainer facing towards
the bow of the vessel.
