Glycol Adding Requirements
Purchase glycol and corrosion inhibitor from a local qualified installation company.
Determine the glycol volume concentration based on the lowest temperature in record in
the area.
As the glycol solution is toxic, avoid skin contact with the glycol solution and splashing
it into your eyes. Dispose of the glycol solution in accordance with local laws.
To prevent glycol solution from corroding pipes and the heat exchanging coil, corrosion
inhibitor should be mixed into the glycol solution. For details about the mixing schemes,
consult glycol experts.
Check the quality of the glycol solution on a quarterly basis and evaluate the
anticorrosion effects. For details, consult local water treatment experts.
