Clayton Feedwater Treatment Manual

Coil Guard 2

Coil Guard 2 is a prestart-up product designed to passivate the coil tube to minimize corrosion. The product is also an excellent wet lay-up corrosion inhibitor to be used when the Clayton generator is laid-up wet for brief periods. Directions for use (when used following Coil Guard 1) 1. Drain the feedwater tank and coil containing Coil Guard 1. 2. Fill feedwater tank with soft water and rinse. Continue this rinsing process until the water is clean with no visible sediment. 3. With the generator filled with soft water, add the appropriate amount of Coil Guard 2 to the system. 4. Recirculate the Coil Guard 2 solution for 2 hours and short fire the generator to raise the water temperature to around 180 o F (82 o C). 5. Drain the Coil Guard 2 solution from the system followed by a rinse with fresh soft water. 6. Fill the feedwater tank with soft water and add the appropriate Coil Guard product; then, start the generator for normal operation. Directions for use (when used as a wet lay-up inhibitor) 1. Add one gallon of Coil Guard 2 per 100 gallons of system capacity. 2. Recirculate for 15 minutes before shutting down the generator in wet lay-up mode. 3. Maintain feedwater residual sulfite above 100 ppm and feedwater pH above 10.0 at all times Dosage Instructions 1% of system capacity (capacity = water in coil + water in feedwater tank) Benefits of Coil Guard 2
