2.3. SYSTEM FLUSHING, TREATMENT, AND CLEANSING

Note that prior to cleaning the heating system, the boiler MUST be isolated from the piping to

prevent infusion of containments, including sludge, into the boiler. Section 2.3 provides recommendations for flushing, cleaning, and treating the water used in the AM Series system.

IMPORTANT!

Cleaning solution and inhibitors used must be compatible with heat exchanger material. Corrosion/scale inhibitor will be ineffective if added to a dirty system; therefore, it is very important to clean the system first.
