General guidelines for introducing propylene glycol into the water circulating system follow. The 
manufacturer’s specific instructions and industry standards always take precedence when 
introducing propylene-glycol to the system. 

 

Calculate the quantity of inhibited propylene-glycol (fluid) required to achieve the 
desired results. 

 

Introduce a sufficient quantity of water to the system and pressure check to ensure a 
sealed system. 

 

Drain some water from the system to provide enough volume for the calculated 
amount of fluid. 

 

Add the correct amount of fluid and any water needed to completely refill the system, 
allowing for liquid expansion due to operating temperature. 

 

Circulate the inhibited propylene-glycol antifreeze solution for at least 24 hours to 
ensure complete mixing. Check the liquid concentration to assure that the correct 
mixture is obtained.
