• check the exterior of the packaging;
• remove all product packaging mate­
rial;
• inspect the product for possible dam­
aged parts;
• contact the retailer if any defects are
found.
Use the original packaging to return the
product to the retailer in the event of de­
fects; otherwise dispose of all packaging
materials according to current local stan­
dards.
Handle the product in obser­
vance of current accident pre­
vention standards.
During storage, protect the product from
humidity, dust, heat sources, mechanical
damage and external contaminants in or­
der to conserve the quality of the water
subsequently placed in contact with the
pump.
INSTALLATION
Install the pump on a flat surface and se­
cure to prevent movement during start­up
and operation, ensuring that there are no
obstructions to the regular flow of cooling
air delivered by the motor fan.
The pump must be installed in a well­ven­
tilated area, and relative humidity in the
environment must not exceed 50% at
40°C (condensate free).
Ensure that the installation site is suffi­
ciently sized to enable assembly of the
pump on the system and future mainte­
nance operations.
Ensure that the pump installation room
or site is not subject to the risk of flooding
by the leakage of liquids or other events
that may cause submersion of the pump
itself.
Ensure that the ambient temperature
does not exceed the values specified on
the data plate.
To avoid breakdown of the sys­
tem with the risk of physical inju­
ry, use pipelines, connectors and
accessories suited to the maximum oper­
ating pressure values.
All pipeline connections must be
made by qualified personnel in
conformity with current local
standards.
To avoid the need to drain the system
in the event of pump maintenance, the
installation of a shutoff valve is recom­
mended, on the suction and delivery pipe­
lines.
If the pump remains in operation
with the delivery valve closed for
more than a few seconds, the liq­
uid will overheat. Never use the pump
with the shutoff valve closed on the deliv­
ery side.
The pump should be installed in such
a way to avoid the risk of air pockets in
the body or pipelines, in particular on the
suction side of the pump.
Pipelines and valves must be correctly
sized according to the installation.
Pipelines must not cause excessive me­
chanical stress on pump suction or de­
livery with excessive loads and torque
values.
If flexible hoses are used, fit a semi­rigid
pipe on suction to avoid the risk of shrink­
age due to negative pressure on suction.
