1-13: General Information
Hard Water Area Map
The hard water map, shown in Figure 1-1, denes hard water areas in the continental
United States which compromise uid related components such as hoses, ttings, heaters,
pumps, valves and water-cooled engines. For other countries, hard water area maps can
be obtained from geological societies.

The map shown in Figure 1-1 is provided for general reference only. Water
hardness in your geographical location should be conrmed by testing.
Water Softener
Cleaning efciency and equipment life is increased, chemical use decreased, and the
appearance of cleaned carpets enhanced when water softeners are incorporated in
hard water areas. HydraMaster strongly urges the use of water softener units with the
Boxxer 318 in areas exceeding 3.0 grains per gallon.
Failure to use a water softener in these areas will invalidate the machine’s warranty.
Referring to the hard water area map shown Figure 1-1, determine the quality of water
in your area and take immediate action if the water hardness exceeds 3.0 grains per
gallon.
The relatively low cost of a water softener service is more than made up for by an increased
life of machine parts, reduced chemical costs and continued cleaning efciency. The
water softener will also increase the effectiveness of the cleaning chemicals, therefore
less chemical will be needed.
