Franklin Electric Hydropompe FWS Series Use And Maintenance Instructions page 19

Rotation direction (for FLV series only)
Check the exact rotation direction by proceeding with the following operations:
- connect the red clamp or the brown wire to the positive pole and the black clamp or the blue wire to
the negative pole;
- start the motor for a few seconds, making sure that the kick-back does not become a danger hazard;
- if the kick-back has been anticlockwise, then the rotation direction is correct;
- if the rotation direction is wrong, disconnect the power supply and reconnect the electric pump to the
mains by switching the wiring connection.

When starting and/or during use, the minimum frequency must not be less than 70% of the rated value.
The motor must be ordered with the type of electric winding that suits the use required.
dV
Voltage gradient
≤ 750
dt
Harmonic content of the voltage ≤ 1.5%. Harmonic content of the current ≤ 4%.
Conditions that must be complied with regardless of the length of the power cables.
6.2 Running and inspections
After the installation conduct regular preventive maintenance inspections at least once every 5000-10000
hours service, according to whether duty is more or less heavy check the following:
