1-15: General Information
Water Softener
Cleaning efficiency 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 CTS 403
Flex 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 efficiency. The
water softener will also increase the effectiveness of the cleaning chemicals, therefore
less chemical will be needed.
Contact a water softener distributor in your area for information on the rental of a simple
water treatment unit to carry in your truck. Be sure to charge the water softener in
accordance with the capability of the softener.
For example: If the softener will treat 900 gallons of water and the machine uses an
average of 30 gallons/hour, for an average of 5 hours a day, this equals 150 gallons per
day). In 6 days the machine would use 900 gallons of water. Therefore, the softener
would need to be charged every 6 working days for maximum softening.
