CAUTION

                                           (2/2) 



Install this product in the proper position as specified in this manual. Excessively tight connection or improper 
installation position might damage the product. Failure to do so might damage the valve body. 



Do not excessively screw the valve into a pipe. Doing so might damage or deform the inside of the valve causing 
leakage and malfunction. 



Install this product so that no foreign objects remains inside the pipes. Be sure to provide a strainer (with 40 or 
more meshes) on the inflow side of the piping. Flush the piping to remove the foreign objects after installation. 
Foreign objects inside the piping might damage the product. 



After installation, make sure no fluid leaks from the valve-pipe connections. Incorrect installation might cause 
fluid leakage. 



When the actuator is removed and mounted again, make sure that the lock lever is firmly closed (locked). The 
actuator might drop and cause injury. 



Do not put load or weight on the actuator of this product. Doing so might damage the product. 



All wiring must comply with applicable codes and ordinances. 



Provide a cutoff device such as a circuit breaker for the power to this product. 



Provide a circuit protector (e.g., a fuse, cut-off device) for the control panel to ensure your safety. 



Use crimp terminals with insulation for connections to the product terminals. Failure to do so might cause short 
circuit leading to fire or device failure. 



Firmly tighten the terminal screws. Insufficient tightening of the terminal screws might cause fire or overheating.



Do not allow the fluid to freeze. Doing so might damage the valve body and cause fluid leakage. 



Do not touch the moving parts of this product. Doing so might cause injury. 



Do not carelessly touch the product since temperature of some parts in the actuator goes high. Doing so you 
might get burned. 



Do not carelessly touch this product when being used to control hot water. The product temperature goes high, 
and you might get burned. 

Do not disassemble this product. Doing so might cause device failure. 



Dispose of this product as industrial waste in accordance with your local regulations. Do not reuse all or part of 
this product. 

 

 

IMPORTANT 

In order to prevent damages by freezing while it is not used in winter, fully open the valve to drain water out of the pipes, 
and then open and close the valve once. Failure to do so, the water in the valve might freeze and expand to damage the 
valve.
