5. Setup and Installation
5.1 Site Selection
- Choose a dry, level, and well-ventilated area for pump installation.
- Position the pump as close as possible to the pool's plumbing and a suitable electrical outlet.
- Ensure the location allows for easy access for maintenance and service.
5.2 Electrical Connection
- Verify Voltage: Before connecting the pump to power, carefully check the voltage selector switch on the motor. Ensure it is set to match your power supply (115V or 230V). Refer to Image 2.1 for the location of the voltage selector.
- Grounding: Ensure the electrical outlet is properly grounded. Use a dedicated circuit if possible.
- Power Cord: Connect the pump's power cord to the appropriate grounded outlet.
5.3 Plumbing Connection
- Identify the pressure-side return line from your pool's filtration system where your pool cleaner operates.
- Connect the provided durable hose to the pump's outlet and to the inlet of your pressure-side pool cleaner.
- Use the quick-installation fittings to secure all connections. Hand-tighten fittings first, then use a wrench for a snug, leak-free seal. Do not overtighten.
- Ensure there are no kinks or obstructions in the hose.

6. Operating Instructions
6.1 Initial Start-Up
- After completing the installation, ensure all plumbing connections are secure and leak-free.
- Verify that the pump is receiving water from the pool's filtration system. Booster pumps typically do not require manual priming if connected to a pressurized line.
- Turn on the power to the pump. The pump should start immediately, providing increased pressure to your pool cleaner.
6.2 Normal Operation
- Once running, the booster pump will continuously supply high-pressure water to your pressure-side pool cleaner, allowing it to operate efficiently.
- Monitor the pump for any unusual noises or vibrations. The DASENAIR PBS075 is designed for ultra-quiet operation.
- Regularly check the performance of your pool cleaner to ensure optimal debris removal.
