8. PREPARING FOR USE
WARNING!
Installation must be carried out by a qualified engineer.
Free the pump from the packaging and lift it and lower it
with suitable lifting gear in compliance with safety rules.
Note that the motor's lifting hooks are not suitable for
lifting the motor-driven pump.
8.1 COUPLING TO THE MOTOR
The motors to be coupled to the EVMSN pumps must meet IEC standards and
must have the preload spring positioned as illustrated:
WARNING!
Required the presence and the installation of the
preload spring as indicated in the drawing above.

Motor/pump coupling operations must be carried out with the motor
disconnected from the power supply.
Since it is best to perform a trial run following coupling to check operation, if there
is enough room, we suggest you perform coupling once the pump has been
fastened down in its working position and connected to the suction and delivery
lines. Otherwise the trial run can be performed with fluid piping connected in a
makeshift manner.
