 Safety Considerations 

 

Follow installation guidelines to ensure the product functions properly and as intended.  

Improper installation and use may result in such hazards as damage to the product or malfunctions that 
may lead to injuries or damage. Failure of the product to function may result in problems occurring in 
the system, such as equipment flooding with condensate or improper drainage.  
 
See page 9 & 10 for System Troubleshooting. 
 

When disassembling or removing the product, wait until the internal pressure is relieved 
and the product has cooled to room temperature.  

Disassembling or removing the product when it is hot or under pressure may lead to injuries or damage. 
  

Do not excessively over tighten or torque when connecting piping to the product.  

Over-tightening may cause cracks and damage to the product which may lead to fluid discharge, which 
may cause injuries.
