Safety Considerations 

• 

Read this section carefully before use and be sure to follow the instructions. 

• 

Installation, inspection, maintenance, repairs, disassembly, adjustment, and valve 
opening/closing should be carried out only by trained maintenance personnel. 

• 

The precautions listed in this manual are designed to ensure safety and prevent 
equipment damage and personal injury. For situations that may occur as a result 
of erroneous handling, three different types of cautionary items are used to 
indicate the degree of urgency and the scale of potential damage and danger: 
DANGER, WARNING and CAUTION. 

• 

The three types of cautionary items above are very important for safety: be sure to 
observe all of them as they relate to installation, use, maintenance, and repair. 
Furthermore, TLV accepts no responsibility for any accidents or damage occurring 
as a result of failure to observe these precautions.

conditions quoted. 

 

Take measures to prevent people from coming into direct 
contact with product outlets. 

Failure to do so may result in burns or other injury from the 
discharge of fluids. 

 

When disassembling or removing the product, wait until the 
internal pressure equals atmospheric pressure and the surface 
of the product has cooled to room temperature

Disassembling or removing the product when it is hot or under 
pressure may lead to discharge of fluids, causing burns, other 
injuries or damage. 

 

Be sure to use only the recommended components when 
repairing the product, and NEVER attempt to modify the
