4.3. Valves and Fittings
1) Elbows should be no closer than 12in to the inlet. Do not install 90° elbows directly into the pump
inlet/outlet. Joints must be tight.
* The pump inlet/outlet union size: optional with metric (48.5 or 60.3mm) or imperial (1.5” or 2”)
2) Use a check valve in the return line where there is a significant height between the return line and the
outlet of the pump.
3) Be sure to install check valves when plumbing in parallel with other pumps. This helps prevent reverse
rotation of the impeller and motor.

2) Check whether power supply voltage and frequency conform to the nameplate;
3) Facing the fan blade, the direction of motor rotation should be clockwise;
4) Do not run without water. Will the basket initially before starting the product.
