Determine which direction you want pump outlet fitting to point after installation. Mark pump base and mounting pad in desired position. If Automatic Float Switch is to be installed, allow enough room on pad for shim and switch. 2. Remove pump base from motor housing by depressing lock button and twisting clockwise. 3. Align base with pad at marks, and fasten with four #8 screws. 4. Attach pump to base by aligning four retaining tabs and twisting counterclockwise until the lock button snaps into place. AUTOMATIC FLOAT SWITCH INSTALLATION Figure 3 Bilge Pump Automatic Float Switch • • • Float Switch Must Shut Pump Off Before the Pump Cavitates (Draws Air and Stops Pumping) • Shim Test Knob • 1. Select a location on the pump mounting pad forwardof the bilge pump. NOTE: It is important to locate the switch forwardof the pump to minimize the possibility of running the pump when there is not enough standing water, causing the pump to draw air and not turn off. 2. Attach shim to mounting pad with a layer of polyester resin. 3. After resin has dried, center automatic float switch on top of shim. If you have an Attwood switch withouta cover, thread two #8 screws through attachment holes on switch. Fasten securely into mounting pad. If you have an Attwood switch witha cover, thread three #8 screws through cover, then switch. Fasten securely to mounting pad. HOSE CONNECTION INSTRUCTIONS 1. If no thru-hull connector exists: Install connector well above the water line (just under the rub rail is best) on the driver side, where water discharge can be easily monitored. Drill a hole through the hull to clear the connector threads. Apply marine sealant around inside of nut flange (do not allow sealant to contact pump housing). Fully insert thru-hull connector, and screw nut flange down firmly. Do not over tighten. 2. Run hose from pump nozzle up to thru-hull connector, through the most direct and unobstructed path possible. 3. Before connecting hoses, cut any extra length from hose that causes downward dips or kinks in discharge line (dips can trap water and airlock the pump). Be sure the hose tension on the pump outlet is minimized to reduce stress on the pump components. 4. Place hose clamps onto hose ends. Connect ends to pump nozzle and thru-hull connector, ensuring that hose ends fit tightly over barbs. 5. Secure both connections with hose clamps.
