of the pump, it is recommended that the check valve not be used. Also, when winterizing your boat,
remove the check valve to avoid ice formation and/or degradation of the check valve.
7. Select a point where the bilge water is to be pumped overboard as high as possible above the water line
and at the shortest distance from the pump. Install a 1-1/8" (29mm) or 1-1/4" (32mm) thru-hull fitting.
8. Fasten a 1-1/8" (29mm) or 1-1/4" (32mm) fuel-resistant hose from the pump outlet to the thru-hull fit-
ting. Avoid sharp bends or loops. Support the hose if necessary. Note: In order to prevent air locks it is
important that the hose not be allowed to dip below the pump outlet. The hose should be
constantly rising.
9. Connect the brown wire to the positive (+) terminal of the battery, and the black wire to the negative (-)
terminal of the battery. See wiring diagram, pages 10-11.
10. Important: All electrical wiring must be clamped with the connections well above the bilge water level.
Do not remove the insulation more than necessary. All wiring connections should be sealed with a
marine sealant to avoid oxidation.
Maintenance
Regularly check the pump to be sure that the filter base and impeller are not clogged with debris. To clean,
push in the tabs and lift up the pump housing. Note! The discharge hose need not be removed.
