  Defects in the raw water supply solenoid valve. 

No water is supplied to boiler. 

  Defect of float switch. 

  Defect of boiler water supply solenoid valve. 

Heater does not turn on. 

  Defect of float switch.

disconnection. 

Distillation does not stop. 

  Defect of float switch. 

 

When power failure occurs… 

  When power is supplied after a power failure, the device automatically starts operation again with 

the same state as just before the power failure. It is danger that the device starts unattached 
operation after a power failure. 

  We recommend for you to turn off the switch of device if a power failure occurs during operation. 

 

 

 

In the case if the error other than listed above occurred, turn off the power switch and primary 
power source immediately.  Contact the shop of your purchase or nearest Yamato Scientific
