  PRECAUTIONS FOR SAFE OPERATION 

 
 
 
 
 

Use a dedicated power source

 (a dedicated circuit with a breaker) as indicated on the rating label 

attached to the unit.    A branched circuit may cause fire resulting from abnormal heating. 
 

Connect the power supply plug to the power source firmly after removing the dust on the plug.

   

A dusty plug or improper insertion may cause a heat or ignition. 
 

Never store corrosive substances such as acid or alkali

 in this unit if the container cannot be 

sealed.    These may cause corrosion of inner components or electric parts. 
 

Check the setting when starting up of operation after power failure or turning off of power 
switch.

    The stored items may be damaged due to the change of setting. 

 
Be careful not to tip over the unit

 during movement to prevent damage or injury. 

 
Prepare a safety check sheet

 when you request any repair or maintenance for the safety of service 

personnel.
