Appendix

Requirement on the Voltage Supply

Power supply in some areas is unstable. Excessive

fluctuations in power supply affect the use of equipment,

and even cause damage to the pump.

JLM-S solenoid metering pump power supply

range is ± 10% of the rated voltage(for details, please

refer to the relevant technical information).

For areas where the supply voltage fluctuates or

the surge voltage exceeds the allowable range, please

install an AC regulated power supply. Equipment loss

due to over voltage of power supply, our company

does not assume the responsibility of quality

assurance.

Please read the manual carefully before use.
