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.
