Warnings and Cautions 

 WARNING

 

Alerts users that improper handling may cause death or serious injury. 

 CAUTION

 

Alerts users that improper handling may cause minor injury or material loss. 

 

Signs 

 

Alerts users possible hazardous conditions caused by erroneous operation or erroneous use. The symbol inside I 
indicates the specific type of danger.  
(For example, the sign on the left warns of the risk of electric shock.) 

 

Notifies users that specific actions are prohibited to prevent possible danger. The symbol inside Q graphically 
indicates the prohibited action.  
(For example, the sign on the left notifies that disassembly is prohibited.)  

 

Instructs users to carry out a specific obligatory action to prevent possible danger. The symbol inside d graphically 
indicates the actual action to be carried out.  
(For example, the sign on the left indicates general instructions.) 

 

 CAUTION 

 

Install and use this product under the operating conditions (for temperature, humidity, power, vibration, shock,
mounting direction, atmosphere, etc.) listed in the specifications. Failure to do so might cause fire or device failure. 

 

Use the product within its lifespan and avoid instrumentations that keep the product to operate excessively. 
Continued use beyond the lifespan might cause fire or device failure. 

 

Keep the products in package for storage. Failure to do so might damage or stain the products. 

 

Installation and wiring must be performed by qualified personnel in accordance with all applicable safety standards.

 

For installation, do not mount the valve in an improper position or overtighten the threaded connections. 
Doing so might damage the product. 

 

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

 

Install the product so that no foreign objects remains inside the pipes. Be sure to provide a strainer 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. 

 

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

 

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

 

Do not install the product nearby a steam coil, pressurized hot-water coil, or any high heat source. High temperature 
radiation might cause malfunction of its actuator. 

 

Do not use the product in an atmosphere corrosive to the actuator, valve, and their components. Doing so might
damage the product. 

 

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

 

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

 

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