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 EVMS 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.
