OOPS!!! Sorry bout dat!!! Try these instructions for external installation.
1. Connect outlet hose from the aerator outlet fitting to the Spray
Head. Use a hose clamp at each end of the hose. (Figure 3)
IMPORTANT: Route the hose as straight as possible with an upward
angle. Avoid dips or sharp bends that can create airlock and hinder
water flow.
2. An aerator pump can be connected to the bottom of a livewell to
recirculate water within the tank.
WIRING INSTRUCTIONS
The power source to the pump must be a 12-volt DC battery ONLY.
Protect circuit with fuse (see chart) and make all wire connections
above the highest possible water level, using marine grade wire
connectors only. Waterproof all connections with suitable materials.
