3)At the installation of equipment, inlet positive pressure installation should be adopted, avoiding negative pressure suction installation wherever possible. if negative pressure installation must be adopted, please select a bottom valve with good quality, and carry out periodical maintenance.

4)The inlet pipe and outlet pipe of variable frequency pump must be larger than the pipe diameter of the pump in diameter

5)Please note whether the power supply provided meets the requirement for incoming power supply of variable frequency pump.

6)At installation, the user should provide inlet and outlet valves for variable frequency pump, and flexible joints for connection, which facilitate maintenance and prevent noise from transmitting through pipeline.

7)When inlet positive pressure installation is adopted, please open the vent valve of pump to exhaust air before use, and close it until water comes out.
