Any good water treatment compound, used in the recommended quantity, will provide
free oxygen control and proper pH adjustment during operation and can be metered
into the soft water being supplied to the cleaner through the cleaner's regular
soap system, instead of soap.
Sizing
of
Water
Softeners:
1.
Determine feedwater hardness in grains per gallon (1 grain per gallon
equals 17.1 parts per million). Example: 342 p.p.m. equals 20 g.p.g.
2.
Determine gallonage between the required regeneration periods (grains
per gallon times gallons per hour capacity of cleaner, times hours of
daily or weekly use, times 1.15 - 15% safety factor) equals size
required.
342 parts per million hardness used
Model 200-A0 (200 g.p.h.).
Example:
4 hours per day - 6 days per week (342 p.p.m. divided by 17.1 =
20 grains per gallon). Objective:
