  • Page 7: Dosatron Technology

    Technology Unique technology that incorporates all dosing functions. Installed on the water supply line, the DOSATRON uses water pressure as the only power source. When activated, it draws in the concentrate, doses it to the desired percentage, and mixes it with the motive water. The resulting solution is then propelled downstream.

    INSTALLATION TIPS The DOSATRON must be assembled in by-pass as shown below. An in-line assembly is possible but not recommended because it does not enable the dosing pump to be easily isolated for maintenance (necessary to cut off the water supply).
  • Page 28 To prolong the service life of the DOSATRON, we recommend fitting an upstream filter (e.g 130 microns - 120 mesh, depending on your water quality). This precaution is essential if the water contains impurities or particles, especially when using water from a well or surface water The filter is recommended and required for the warranty to be valid.
