4. Installation Guide
The CrestWave FLO300 pump is designed for easy DIY installation. Follow these steps carefully:
4.1 Pre-Installation Checks
- Ensure the installation area is clean, dry, and has access to a grounded electrical outlet.
- Confirm that the pump will be used for greywater only.
- Verify that the discharge pipe system is clear and correctly sized.
4.2 Connecting Inlets and Outlet
- Position the pump in a suitable location, ensuring it is level and stable. The compact size (33L x 16.3W x 17.3H cm) allows for placement in tight spaces.
- Connect the greywater sources (sink, shower, bathtub, laundry) to the three available inlets using the provided rubber tubes and hose clamps. Ensure connections are secure and leak-free.
- Attach the elbow assembly with the built-in check valve to the pump's outlet. This check valve prevents backflow of water.
- Connect the discharge pipe to the elbow assembly. Ensure the discharge pipe has a slight downward slope (minimum 3 degrees) towards the pump if connecting horizontally, to facilitate gravity flow into the pump.
- The pump is suitable for various pipe sizes. Use appropriate adapters if necessary.

4.3 Electrical Connection
- Plug the pump into a standard 115V/50Hz grounded electrical outlet.
- Avoid using extension cords if possible. If an extension cord is necessary, ensure it is rated for outdoor use and is properly grounded.
