and run it at maximum speed with the delivery valve turned downwards. After running for a few minutes, check
to see whether water is still coming out.
- Install the pump in a zone where the environment temperature does not exceed 104º F and the relative
humidity is below 90%. The pump has an NEMA 4X protection level.
- Install the pump so that any inspection and maintenance operations are easy to carry out, then secure the

OPERATION.
The pumps have been designed to absorb
small over voltage. Therefore, in order to
prevent the pump from being damaged, it is
always preferable to ensure that the pump
does not have a power source shared with
electrical appliances that generate high
voltages.
Connection with the three-phase 440V line
should only be made between hot and
neutral. Connections must not be made
between hot and earth.
