4. Installation and Setup
4.1. Placement
Place the pump on a stable, level surface within your pond or water feature. Ensure it is fully submerged and positioned to draw water effectively without pulling in excessive debris from the bottom. Avoid placing the pump directly in heavy sludge or loose gravel.
4.2. Plumbing Connection
Connect the appropriate plumbing (e.g., flexible tubing or PVC pipe) to the pump's discharge outlet. Ensure all connections are secure and watertight to prevent leaks and maintain optimal flow. Refer to your specific plumbing requirements for proper sizing and sealing.
4.3. Electrical Connection
Route the power cord to a GFCI-protected outdoor electrical outlet. Ensure the cord is protected from damage and is not pinched or strained. Do not use extension cords unless absolutely necessary and ensure they are rated for outdoor use and properly grounded.
5. Operation
Once the pump is properly installed and submerged, plug the power cord into the GFCI-protected outlet. The pump should start immediately, circulating water. Monitor the initial operation to ensure proper flow and check for any unusual noises or vibrations. The Tidal Wave L-310 is designed for continuous operation.
6. Maintenance
6.1. Regular Cleaning
Periodically inspect the pump intake for debris accumulation. Disconnect power before removing the pump from the water. Clean the pump housing and impeller area to remove any leaves, algae, or other obstructions that may reduce flow or strain the motor. Use a soft brush and clean water.
6.2. Winterization
In regions with freezing temperatures, remove the pump from the pond before the first hard freeze. Clean the pump thoroughly and store it in a frost-free location, submerged in a bucket of water to keep seals lubricated, or follow manufacturer recommendations for dry storage.
