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. 

Symbols 

 

Indicates a DANGER, WARNING or CAUTION item. 

 

DANGER

 

Indicates an urgent situation which poses a threat of death or 
serious injury 

 

WARNING

 

Indicates that there is a potential threat of death or serious injury 

 

CAUTION

 

Indicates that there is a possibility of injury or equipment / product 
damage 

 

Install properly and DO NOT use this product outside the 
recommended operating pressure, temperature and other 
specification ranges. 

Improper use may result in such hazards as damage to the product 
or malfunctions that may lead to serious accidents. Local regulations 
may restrict the use of this product to below the conditions quoted.

 

Use hoisting equipment for heavy objects (weighing 
approximately 20 kg or more)

Failure to do so may result in back strain or other injury if the object 
should fall.

 

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.

 

 

CAUTION

 

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.

 

Safety considerations are continued on the next page.
