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.
