Mind the following notes on the installation of the seawater system:
•
The seawater pump must be mounted so that it is always at least 300 mm
below the water line.
•
The seawater pump may be mounted horizontally or vertically, however the
discharge must always be above the inlet (fig. 7, page 6).
•
Ensure the water is flowing freely from overboard discharge while the pump
