1. PUMPED FLUIDS
The machine has been designed and built for pumping water, free from explosive substances and solid particles or fibres, with a density of 1000
kg/m³ and a kinematic viscosity of 1 mm²/s, and chemically non-aggressive liquids. Use with other fluids is allowed only with the manufacturer's
authorization.

3. MANAGEMENT
3.1 Storage
All the pumps must be stored indoors, in a dry, vibration-free and dust-free environment, possibly with constant air humidity.
They are supplied in their original packaging and must remain there until the time of installation. If this is not possible, the intake and delivery
aperture must be accurately closed.
3.2 Transport
Avoid subjecting the electropumps to needless jolts or collisions. The figures below indicate respectively how to lift single electropumps – Fig.
5A-6A-7 pag.73– and twin versions – Fig. 5B-6B-7 pag.73 – during installation, after they have been removed from the packaging
3.3 Weights
The adhesive label on the package indicates the total weight of the electropump.
4. WARNINGS
4.1 Checking motor shaft rotation
Before installing the pump you must check that the rotating parts turn freely. For this purpose, proceed as follows on the pump concerned:
remove the fan cover from its seat in the motor end cover, loosening the nuts. Move the fan by hand to turn the motor shaft a few times. If this
is not possible, dismantle the pump body, slackening the screws to check whether there are any foreign bodies inside it. To disassemble, proceed
in the inverse order to assembly.
Do not force the fan with pliers or other tools to try to free the pump as this could cause deformation or breakage of
the pump.
