Checks before commissioning
•
Make sure that the voltage and frequency correspond to the values stated on the nameplate of
the motor.
•
Make sure that the condenser matched the requirements of the pump (single-phase).
•
Make sure that the suction via the hose is correct.
•
Check the direction of rotation.
•
Never let the pump run dry.
•
Never change the position of the floating switch as set up by the manufacturer.
Maintenance
Our pumps do not need special maintenance; nevertheless we urge you to obey the following ad-
vice:
•
During cold seasons and by low ambient temperature, empty the outlet line.
•
If not used for a long time, the pump should be cleaned and stored in a dry place to avoid
corrosion.
