Installation and usage
- Before use, check whether the components are damaged during transportation, and then install and use.
- During installation, pay attention to whether the medium flow direction and the pipe thread are correct (the medium must be filtered through a filter screen of 40μm or above).
- Pay attention to whether the installation conditions meet the technical requirements (such as rated voltage, operating frequency, working pressure, operating temperature range, etc.), and then install it horizontally.
- Try to avoid using it in a vibrating environment and pay attention to anti-freezing measures in low temperatures.
