Part Number; Size
- SR2-1 1 gallon 4/cs
- SR2-5 5 gallons
Directions:
- Drain and flush system.
- Remove all loose debris. Clade bleed-off valve where applicable.
- Fill the system with fresh water.
- Add 1 gallon of Scale Remover No.2 for every 15 to 20 gallons of water in the system.
- Allow for water in the piping.
- Circulate solution until the scale is removed or the acid is spent.
- One pH indicator strip shows when the acid solution is neutralized. One or more additional dosages may be necessary for heavy scale.
To repeat dosage, add more Scale Remover No. 2 in the same 20 to 1 ratio used initially, then bleed enough water from the system. Repeat steps 1 through 3. Drain the system completely before proceeding with another dosage. Do not use more than 2 doses with the same water. After cleaning, thoroughly flush the system before refilling with fresh water. Adjust the bleed-off valve as necessary.
