Submersible bilge pump for pumping bilge water in marine environment. To be installed in the keelson. Installation
Please follow the installation instructions carefully to assure maximum efficiency in your bilge pump operation.
- Remove the strainer from the bottom of the pump by depressing the lock tabs on both sides of the pump.
- Determine the desired location for the pump. Usually it is placed in the lowest point of the bilge.
- Position the strainer so that the pump nozzle is in the proper position to connect to the discharge hose.
- Mount the strainer. If attaching the strainer to wood, fasten with stainless steel screws. If attaching the strainer to metal or fiberglass, first mount a wooden block and then fasten the strainer to the wooden block.
- Mount the pump on the strainer so that both locktabs ”snaps” into place.
- 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 1½"[L2200/ L4000] or 1¹? 8 " [L1600/L2200] or 2"[L4000] thru-hull fitting. Note: The L4000 pump comes equipped with an integrated check valve to minimize back flow of water, however, over time water will seep back into the hull when the pump is not running. The use of flapper check valve will reduce maximum flow performance.
- Fasten a 1½"[L2200/L4000] or 1¹? 8 " [L1600/L2200] or 2"[L4000] fuel resistant hose from the pump outlet to the thru-hull fitting. 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.
- Connect the brown wire to the positive (+) terminal of the battery, and the black wire to the negative (-) termal of the battery. See wiring diagram, page 16-17.
- 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.
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.
