1 quart of Sentinel X300 is sufficient to treat a typical residential system of 25 gallon. Larger systems should be dosed at 1% of system water. If the system is new, this should be at the time it is first filled. For best results, the water should be circulated at normal operating temperature for between 1-2 hours but no longer than 24 hours. If it is not possible to heat the water, the circulation time must be compensated for by extending the time to at least 24 hours but no longer than one week.

Drain and flush the system before refilling and treating with Sentinel X100 Inhibitor.
