- Connect the electric motor according to local applicable rules
and regulations. The electrical installation work must be carried
out by qualified personnel.
- Check that the optional electrical components are connected
and are working properly.

8.3 Correct installation of the pump
- Ensure that the pump has not been damaged during
transportation or storage. Immediately report any damage to
the supplier.
- Ensure that all the packaging has been removed.
- Check that the information printed on the identification plate
corresponds with the order.
- Check the operating instructions in order to ensure that the
flow values, pressures & power consumption of the motor do
not exceed rated values.
- Ensure that the hose is suitable for the fluid to be conveyed
and that it is not damaged.
- Make sure that the temperature of the liquid does not exceed
the recommended temperature range.
- Ensure that there is enough space for free airflow around the
motor.
- Ensure that no nearby objects or direct sunshine radiate
additional heat to the motor.
8.3.1 Suction side
- Install a manometer in the pressure line if the back-pressure
value is unknown. Maximum pressure on suction/inlet side is 3
bar (45 psi approx.).
- The pump is to be positioned as near as possible to the liquid
container, so that the suction side is kept as short and straight
as possible.
- The suction line must be absolutely airtight and made of a suit-
able material, so that it does not collapse under vacuum.
- The diameter must correspond to the rated diameter of the
pump hose. A larger diameter is recommended in the event of
viscous liquids.
- The pump is self-priming and does not require an admission
valve.
