1.The pump foundation should be rigid enough to absorb any vibration from the motor, and the
pump should be securely bolted to the foundation.

damage in case of leakage, particularly when installed indoors. When it is installed outside, it
should be covered by a weather-proof housing, well ventilated to allow motor heat to escape.

3. Connect the suction pipe to the side and discharge pipe on the top.( See Fig 1 )

4. When it is installed with water heater, a check valve should be installed between pump
(discharge) pipeline and water heater (suction) to avoid high-pressure steam backflow.

run cut off function.

6. To avoid your furniture damage, do not install the pump on ceiling, carpet or any place close to

7. The electrical connection should be carried out in accordance with local regulations. The
operating voltage and frequency are marked on the nameplate. Please make sure that these data
match with your job requirement. For your safety, be sure the Residual current device (RCD,
