To install the welldana 36-140010 AquaGreen 3-Speed Pump, follow these steps:
1. Pump Location:
- Place the pump as close to the pool as possible to reduce friction loss.
- Avoid direct sunlight or heat by installing the pump indoors or in the shade.
- Do not install the pump in a damp or non-ventilated location. Keep it at least 150mm away from obstacles for proper air circulation.
- Install the pump horizontally and fix it in the support hole with screws to prevent noise and vibration.
2. Piping:
- Use a larger pipe size for improved pool plumbing.
- Use thread sealant when installing the inlet and outlet fittings.
- Ensure that the piping on the suction side of the pump is the same or larger than the return line diameter to avoid air suction and reduce pump efficiency.
- Keep the plumbing on the suction side as short as possible.
- Install a valve on both the pump suction and return lines for easy maintenance. The valve on the suction line should be no closer to the pump than five times the suction line diameter.
- Use a check valve in the pump outlet piping system to prevent water hammer and medium recirculation impact.
3. Valves and Fittings:
- Do not install 90° elbows directly into the pump inlet. Keep them at least 250mm away from the inlet.
- Ensure tight joints and that the suction line diameter is equal to or larger than the discharge line diameter.
- Install gate valves on suction and discharge pipes for maintenance in flooded suction systems. The suction gate valve should be no closer than five times the suction pipe diameter.
- Use a check valve in the discharge line when there is significant height to the plumbing after the pump.
- Install check valves when plumbing in parallel with another pump to prevent reverse rotation of the impeller and motor.
