Ecolab EcoAdd Instrucciones De Servicio página 393

Applies only to EcoAdd:
When calibrating the pump, the metering frequency at 100% is varied so that
the nominal metering capacity [l/h] is always met, irrespective of component
tolerances or on-site conditions. The actual metering frequency at 100% may
therefore be less than the "Max. metering frequency" specified in the technical
data.
NOTICE!
Tightening torques
It is essential that the tightening torques given below are observed, firstly to
ensure the leak-tightness of the system and secondly to ensure the integrity of
the thread. The tightening torques are also given on an adhesive label that is
affixed to the pump head.
