How to Operate 

 
 
 
 

5-1. Preparation for start-up 

 
Before supplying power, read and understand the following precautions. Ignoring these precautions may 
cause an electric shock or damage the pump unit. 
 

  Check that the pump unit is installed properly. 

  Check that the pump unit is connected to a grounding circuit. 

  Check that the wiring is connected to external device properly. 

  Check that the tubes are installed properly. 

  Check that the power supply voltage is compliant with the power supply specification and does not 

exceed the rating. 

 
 

5-2. Basic operating procedures 

 
Normally, the detection mode is activated after the power is turned on. 
 

 

 
 

<<Detection Mode>> 

The pump unit is 
restarted after 
recovering from fault. 

<<Fault Status>>
