Product Overview

8. MAINTENANCE (Con’t)
Be sure to drain adequate fluid from system before adding the additional Cryo-tek -100/AL.
The proprietary inhibitor used in Hercules Cryo-tek -100/AL has an exceptionally long life expectancy.
The pH of the system solution should always be between 7.0 and 8.5.
If the corrosion inhibitor tests low, add one 8 oz. container of Cryo-tek -100/AL Inhibitor in accordance with inhibitor
label instructions for every 20 gallons of fluid capacity of the system. If the total system capacity is less than 20 gal-
lons, add one 8 oz. container of Cryo-tek -100/AL Inhibitor. If after inhibitor addition and thorough system mixing, the
corrosion inhibitor pH still tests low, add another 8 oz. container of Cryo-tek -100/AL Inhibitor for every 20 gallons of
system capacity. If after this addition the inhibitor still tests low, the system should be drained, cleaned, and recharged
with fresh Cryo-tek -100/AL.
