2. General information
These installation and operating instructions apply to Grundfos
DSS (dosing skid system) systems equipped with Grundfos
dosing pumps.
The proper functioning of a DSS system depends on the following
points:
•
correct operation
•
regular maintenance
•
calibration of the pump after installing the service kit and
periodic re-calibration of the pump
•
installation of service kit as recommended by individual DSS
component manuals, ie manuals for dosing pumps, back
pressure and pressure relief valves.
