Pentek PCC-106 Phosphate Crystal Water Filter Insert

Recommended for use with ice machines, coffee and vending machines, food service equipment, water heaters, air conditioning equipment and many other types of water processing equipment. Keeps hardness particles separated so they cannot precipitate and form deposits when heated. Maximum hardness 15 grains per gallon (gpg). The Pentek PCC-106 forms a protective coating on all metal surfaces, safeguarding against acidity/alkalinity, hardness, chloride and other factors which effect the corrosion of water equipment and pipes. pH range 6.5 to 9.0. Keeps dissolved iron, up to 1 ppm, suspended in solution (sequestered), preventing dissolved iron from precipitating, which would cause staining and discoloration. NOTE: Eye irritant. Contains sodium calcium hexametaphosphate. Avoid contact with eyes. In case of eye contact, flush with water for 15 minutes, get medical attention. Keep out of reach of children. NOTE: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system. NOTE: Do not use this cartridge on water that will be carbonated. The Pentek PCC-106 is a Hexametaphosphate Crystal Water Filter Cartridge Insert. Pentek PCC-106 phosphate crystal filters contain food-grade hexametaphosphate that dissolves slowly in water to inhibit scale and rust buildup.
