1.Connect positive lead (brown) to switch. For automatic operation, use Attwood Automatic Float Switch (#4201 or 4202). Connect negative lead (black) to ground.

2.Install fuse holder within 72" (183 cm) of the positive (+) battery terminal. Use standard automotive (SAE J554) glass tube type electrical fuse.

3.To test system, feed water into the pump. If flow appears low, be sure wires have been connected properly: Brown-to-positive (switch), and black-to-negative. Reversed wiring reduces performance and can cause pump failure.

MAINTENANCE AND TROUBLESHOOTING

Disconnect power to the pump. Regularly inspect and clean to be sure that debris is not blocking the strainer or impeller.

If pump runs but does not pump water:

1.Check for airlock. Be sure that outlet hose runs upward to the thru-hull connector, with no dips. (Figure 1)

2.Remove pump housing from base. Remove debris from chamber and impeller. Be sure impeller is firmly attached to shaft and is not cracked or broken. (Figure 2)

If pump does not run:

1.Check fuse. Be sure electrical connections and fuse are waterproof and haven’t loosened. (Figure 3)

To replace motor cartridge:

1.Hold pump housing, depress motor cartridge tab and twist cartridge counter-clockwise to remove (Figure 2).

2.Check motor cartridge fit: See specification chart for replacement motor cartridge number. Motor must match housing color:

500 Series = RED, 800 = BLUE, 1200 = GRAY.

3.To reinstall cartridge: Coat O-ring with vegetable oil (petroleum-based oils will cause deterioration).

4.Insert cartridge into housing. Twist clockwise until you hear tab snap up into slot. (Figure 2)
