8.3 Installing the seawater system
NOTICE!
Failure to follow this procedure will void the warranty.
Observe the following considerations when setting up the seawater system:
• The strainer must be below the pump.
• Hoses must be double clamped.
• Hoses must not have kinks, loops, or high spots where air can become trapped.
• The pump and strainer must be below the water line.
• The thru-hull inlet, ball valve, hose, and strainer should be no smaller than the pump inlet.
• Install the thru-hull fitting as far below the water line as possible.
• The pump must have a dedicated thru-hull.
• Avoid 90.00 °elbow fittings as much as possible.
• Ensure that the pump head is rotated toward the direction of water flow.
• Use plumbers tape on all threaded connections.
Refer to Table 2: Operating water temperature and pressure
