components (pump, motor ...), refer to the drawings and technical documentation. If necessary, contact the
technical support service.
•
Make sure that the lifting means adopted have a capacity adequate to the load to be lifting and that they are
in good condition.
•
Do not pause or pass under the load during lifting or transport.
