CONNECTION TO THREE PHASE STARTERS
A direct on line starter incorporating thermal overload and fuses must be used with all three phase motors,
otherwise warranty will be void. Use of non approved fuses may not protect your motor and void warranty.
CHECK ROTATION OF BOTH SINGLE AND
THREE PHASE MOTORS
Both single and three phase motors connected to a supply for the first time may rotate in either direction. It is
therefore necessary to find out if the motor is rotating in the correct direction. Motor shaft rotates
anticlockwise viewed from the lead grommet end. Change rotation by reversing wires.
If rotation is to be checked on the surface, proceed as follows:
Pour clean water into discharge by holding the non-return valve open so that the shaft bearings and the
impellers become wet.
Turn on the power switch and check the shaft rotation is correct.
WARNING:
The dry running should not exceed 2 to 3 seconds, otherwise seizing may occur due to inadequate
lubrication.
