1-9: General Information
local Water Precautions
The quality of water varies greatly. Many areas have an excess of minerals in the water
which results in what is commonly called “hard water.” These minerals tend to adhere to
the insides of heater coils and other parts of the machines causing damage and a loss of
cleaning effectiveness. This influences the reliability and efficiency of equipment in direct
proportion to the level of hardness.
HARD WATER ADVISORY
HydraMaster recognizes that any hard water deposits which might occur within the water
system of our truckmounts is a serious problem. The precision technology of truckmount
heat exchanger systems is intolerant of any foreign material. Hard water deposits will
ultimately decrease the performance of the system and are expected to seriously lower
the reliability of the machine.
To validate a machine’s warranty, HydraMaster requires that all machines operating in
designated “Hard Water Areas” (3.0 grains or more per gallon) be fitted with a water
softening system, or a properly installed magnetic-type descaler must be used and
maintained. Periodic descaling or acid-rinsing alone is not adequate in these areas.
HydraMaster does not recommend any particular type or brand; however, the relative
effectiveness of some types of magnetic descalers or softeners may require additional
periodic use of descaling agents.
HydraMaster also recommends, in the strongest possible terms, that machines in all areas
be fitted with a water softening system for improved operation and reliability.
failure to take appropriate measures to prevent scale build up can result in system failure
and loss of warranty on affected parts.
