5. FIRST PUMP START:
5.1 Direction of rotation:
A correct direction of rotation is essential for proper operation.
Check the direction of rotation with the arrow on the pump-casing.
This can be done by observing the direction of rotation of the motor or coupling.
5.2 Current-check:
The current must be checked during normal operation.
Apply an ammeter to one of the phase wires and check if the current is not higher than
the value stated on the motor data-plate. If this is the case, check for:
-
low voltage ?
-
Specific gravity or viscosity too high ?
-
blocked volute ?
-
direction of rotation correct ?
If the problem cannot be solved contact your dealer or the manufacturer service department .
5.3 Start frequency:
When the pump is controlled by level regulation, the on and off levels should be
adjusted in such a way that the pump does not make more than 20 starts per hour.
