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 

 

 

WARNING 

 

NEVER apply direct heat to the float. 

The float may explode due to increased internal pressure, causing 
accidents leading to serious injury or damage to property and 
equipment. 

 

CAUTION 

 

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. 

DO NOT use this product in excess of the maximum 
operating pressure differential.

 

 

Such use could make discharge impossible (blocked).

 

Use hoisting equipment for heavy objects (weighing 
approximately 20 kg (44 lb) or more)

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