Clayton Feedwater Treatment Manual

STEAM GENERATOR WATER SYSTEM Condition Control and Monitoring

Statement Of Operation Water treatement is required with any boiler or steam generator to protect against corrosion and scaling. Due to the compact design of the Clayton steam generator, the water must be continuously treated and regularly monitored. Daily testing and logging is required to assure normal operation of all feedwater system components. The automatic operation of the total system makes the care and effort required minimal. Departure from specific Clayton guidelines may cause rapid and expensive damage. Such damage is NOT covered by warranty. In case of any questions, contact a Clayton Factory Service representative .
