Important Instruction for MSA/MSV Series
1) Please make sure that this instruction is attached to the pump
2) Make sure that the voltage and frequency is matched. Power supply: 380V/50Hz (or
220V/50Hz, refer to label for details), the motor temperature should be lower than 80 under
normal operation; It is strictly forbidden to operate without liquid for long time (not exceeding 3
minutes)
3) The pump is unable to work at the pressure exceeding its rated pressure (max working
pressure), and its rated pressure value is marked on the label, expressed by bar
(1bar=1kg/cc=10mlift). If the pump works overpressure, it might be damaged.
4) When the chemical to be dosed reacts to water, for example concentrated sulfuric acid, the
chamber must be cleaned and dried (some water drop might be left while testing at our factory)
5) When the adjustment knob is positioned below 100% graduation, the voice from internal
mechanism is relatively big, this is normal, in addition, we suggest you not to position below 30%
graduation.
