Protect the electric pump from freezing temperatures.
For typical applications, a storage tank of suitable size should be provided. For additional information section 10.6.
Do not use the electric pump in environments where chemically aggressive gases or powders may be
present.
Provide adequate lighting and clearance around the electric pump. Make sure it is easily accessible for installation and
maintenance operations.
3.1.9 Power supply requirements
Make sure that the supply voltages and frequencies are suited to the characteristics of the electric motor.
Refer to the pump’s rating plate.
In general, the supply voltage tolerances for motor operation are as follows, if it does not run at full load:
f UN f UN
Hz ~ V ± % Hz ~ V ± %
50 1 220 10 50 3 380 10
50 1 230 10 50 3 400 10
50 1 240 10 50 3 415 10
3.1.10 Sound emission level
Using the electric pump totally submerged, no noise propagates to the outside.
3.1.11 Special applications
Please contact our Sales and Service Department if :
- you must pump liquids with a density and/or viscosity value exceeding that of water as it may be

- pumping liquids that are not compatible with the pump construction materials
- pumping hazardous (toxic, explosive, corrosive) liquids
- pumping drinking liquids (wine, milk,……)
- operating the pump in an explosive atmosphere
- installing the electric pump in a location where the fluid temperature is very high and/or there is poor
ventilation
- installing the electric pump outdoors where it is not protected against freezing temperatures.

Lift and handle the product carefully, using suitable lifting equipment. Observe all the accident prevention
regulations.
The electric pump must never be lifted from the motor cable.
Ambient temperature suitable for storage: ranging from -5°C to +40°C.
When you receive the electric pump, check the outside of the package for evident signs of damage. If the product bears visible
signs of damage, notify our distributor within 8 days from the delivery date.
4.1.1 Additional instructions in case of storage for a long time period (more than 6 months)
Before operating the electric pump after storage, the electric pump must be inspected. Pay particolar attention to the seals and
the cable gland.
The impeller must be rotated every 2 months to avoid the faces of the seal to stick together.
4.2 Unpacking and handling the product Information for installers
