3.5. Pre-start checks

Ensure the voltage and frequency of the
supply corresponds to the values indicated
on the electrical data label.
Ensure that the pump shaft is rotating freely.
Fill the pump body and suction line with water.
Check all joints and connections for leaks.
THIS PUMP MUST NEVER BE DRY RUN.

4. STARTING

Ensure all valves in the pipework are open.
Connect power supply. There will be a delay before
water appears at the end of the discharge pipe.
Viewings from the fan ensure that the rotation of the
motor is clockwise. On three phase pumps the
motor may rotate anticlockwise. If this is happening,
the flow will be lower than expected. To rectify this
situation the two supply phases need to be re-
versed.
Ensure that the absorbed current is the same or
lower than the maximum shown on the name plate.
Adjust the thermal relay if is necessary.
If the pump fails to operate refer to the possible
faults, causes and solutions list for assistance.

5. MAINTENANCE

Under normal conditions these pumps require no
special or planned maintenance.
Clean the pump with a damp cloth without using
harsh products.
We recommend that in cold weather, when
there's risk of freezing, to completely drain
the pipes and pump body by removing the
drain plug.
If the pump is not to be operated for a long
period it is recommended to remove it from
the installation, drain down and store in a dry,
well ventilated place.
ATTENTION: In the event of faults or
damage occurring to the pump, repairs
should only be carried out by an authorised
service agent.
