INSTALLATION INSTRUCTIONS

Installation Method and Place:

It is very necessary to check the following before installation:

•The drive is in good condition.

•Whether the on-site power supply is the same as the rated power on the motor nameplate.

•Whether it meets the environmental conditions (avoid flammable and explosive environment or acid corrosion environment).

Installation Location:

The installation foundation of the pump should generally be level and sufficient-strengthened ground. Install it as far as possible on the lowest position of the equipment, that is, at the position with the maximum head height.

Piping Installation:

The diameter of pump、pipe and the inlet and outlet of the pump should be the same, and the diameter of the inlet pipe should not be too small. When the diameter of the pipe is smaller than the diameter of the pump, adjust it with an eccentric reducer to shorten the diameter of the pipe so as to avoid formation of a gas leak. The outlet pipe diameter must not be too large either. When the outlet pipe diameter is larger than the pump outlet, try to extend it. Distance from the pump outlet to avoid overloading the pump motor.
