Use suitable means for lifting and transporting the pump / electricpump: it may be damaged if it is knocked or
if it falls, even if there is no apparent external damage, and it may also damage things or persons.
Use ropes, straps or chains suitable for the purpose: for the weights of the complete set or of the individual
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.
Always comply with general and local regualtions in force.
The pump is supplied packed in protective packaging which must be removed just before installation.
Appropriate measures must be taken to prevent contamination of materials and articles themselves, in order
not to deteriorate the water quality post then in contact with them.
Storage conditions: store the pump / set in a covered and dry place, lacking dust, freeze and vibrations.
Storage temperature= min 0°C - max 50°C
Metallic exposed surfaces (flanges) must be protected in a suitable way to prevent corrosion.
If you plan to store the pump or the complete set, for a long period of time (more than one month), it is
necessary to perform the following operations monthly:
o
Verify that the preservation status of the pump / complete set and paying more attention to the
non-painted surfaces;
o Check with the appropriate tools, the free rotation of the shaft;
o
Once a month, rotate shaft by hand, in order to keep the bearings protected by the lubricant.
o For any problem replace or recondition the damages parts prior the use.
