USE AND MAINTENANCE MANUAL
PUMP START-UP
DANGER
Use the electric pump according to the performance specifications as stated on the data plate.
DANGER
Always avoid operation of the pump with the upline shutoff valve closed (suction side). Dry running of the
pump can lead to overhearing and damage to the pump itself.
DANGER
Never run the pump with the shutoff valve downline (delivery side) completely closed. In this case, the
water in the system reaches very high temperatures, with the risk of damage to equipment and scalding in
the event of escape of the liquid. In this situation, turn off the pump and leave the system to cool.
DANGER
Never use the pump in the event of cavitation, as this can cause damage to the hydraulic components.
DANGER
Pressure on the downline side of the pump (delivery side) must never exceed the maximum operating
pressure PN as indicated on the pump data plate (see "Application Limits" Figure 5). Pressure downline of
the pump is obtained from the sum of the pressure delivered and the pressure on the suction side (gravity
for installations with negative suction head, aqueducts, or water system where admissible or required).
Check that the shutoff valves
