MANAGEMENT
4.1 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.
4.2 Handling
Avoid subjecting the products to needless impacts or collisions.
The following figures show how single and twin electric pumps must be lifted during installation, after they have been unpacked (see Fig.7
at the end of the booklet).
4.3 Weights
The adhesive label on the package indicates the total weight of the
electropump.
4.4 Checking motor shaft rotation
Before installing the pump, ensure that moving parts rotate freely. To do
this, proceed as follows: remove the fan cover from the seat of the rear
engine cover, unscrewing the blank nuts according to the installation
method. Manually operating the fan, turn the rotor shaft a few revolutions.
If this is not possible, proceed to disassemble the pump body by loosening
the nuts to check for any foreign bodies inside. Proceed in the opposite
direction to that described for assembly.
4.5 New systems
Before running new systems the valves, pipes, tanks and couplings must be cleaned accurately. Often welding waste, flakes of oxide or
other impurities fall off after only a certain period of time. To prevent them from getting into the pump they must be caught by suitable filters.
The free surface of the filter must have a section at least 3 times larger than the section of the pipe on which the filter is fitted, so as not to
create excessive load losses. We recommend the use of TRUNCATED CONICAL filters made of corrosion-resistant materials (SEE DIN
4181):
1- Filter body
2- Narrow mesh filter
3- Differential pressure gauge
4- Perforated sheet
5- Pump intake aperture

PROTECTIONS
5.1 Moving parts
In accordance with accident-prevention regulations, all moving parts (fans, couplings, etc.) must be accurately protected with special devices
(fan covers, ecc.) before operating the pump.
5.2 Noise level
The noise levels of pumps with standard motor are indicated in table A at the end of the booklet. Remember that, in cases where the LpA
noise levels exceed 85 Db(A), suitable HEARING PROTECTION must be used in the place of installation, as required by the regulations in
force.
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.
During pump operation, keep well away from the moving parts (shaft, fan, etc.) unless it is absolutely necessary, and only
then wearing suitable clothing as required by law, to avoid being caught.
