Installing a SHURflo Automatic Float Switch in your boat's bilge system is crucial for effective water removal. Here's how to do it correctly: First, for the pump's location and mounting, position the pump at the lowest point of the bilge, away from engine heat. Secure it with stainless steel screws. Mount the switch horizontally for optimal performance, ensuring it's within a 20-degree angle from vertical. Avoid driving screws through the hull. Next, for the electrical wiring, use 16 AWG wire for leads; if the distance exceeds 20 feet, opt for 14 AWG. SHURflo wires are tinned to resist corrosion. Make all connections with waterproof connectors, ideally above the bilge water level, to prevent corrosion. Twist wires together to minimize radio interference (RFI). Use waterproof splices and connectors, and place connections above the waterline if possible. Always use the fuse size recommended on the bilge pump label, placing it between the battery and the panel switch. For the best setup, consider installing the bilge switch cage. Always test the pump and switch before use. Importantly, never pump oil, diesel fuel, gasoline, or other flammable liquids overboard. Keep all wire connections above the highest possible water level and seal them with a waterproof marine sealant to prevent corrosion. If you're replacing a SHURflo Piranha Bilge switch, follow the specific instructions in the SHURflo manual. This ensures your SHURflo Automatic Float Switch functions reliably, protecting your boat.
