This product must be used in accordance to the following directions by HVACR professionals only.

1. Clean new or lightly corroded existing systems with Nu-Calgon System Cleaner (4370-08) prior to installation of Burst-Kontr’l® AP-100. Do not use with galvanized steel.
2. Extensively corroded existing systems should be cleaned using an inhibited acid such as Season Start Scale Remover or Liquid Scale Dissolver. Job should be handled by an experienced serviceman. All necessary replacements and repairs should be made.
3. The concentration of required glycol-based Burst-Kontr’l® AP-100 will depend on the kind of protection needed. There are two types of protection: burst protection and freeze protection. Burst protection prevents bursting or other mechanical damage, but it is not enough to keep solution pumpable. Freeze protection requires more glycol, and it prevents the formation of ice crystals at the lowest temperature experienced by the fluid. This assure fluid can be pumped at the lowest experienced temperature.
4. Typically, ice storage systems, fire sprinkler systems and intermittently run hydronic systems may be fine with burst protection while chilled water and lawn sprinkler systems need freeze protection.
5. See the chart and select the lowest expected ambient temperature, then go to a temperature 5ºF colder to assure protection. Decide on type of protection and identify the solution percentage that must be made up of Burst-Kontr’l® AP-100.
6. Calculate or establish system volume in gallons and multiply this volume by the percentage identified above. This will tell you the number of gallons of Burst-Kontr’l® AP-100 required.
7. For optimum corrosion protection, a minimum concentration of 30% is recommended.
