7.
Insert the gasket inside the coupling counterflange.
Fasten the counterflange to the pump delivery outlet
with screws.
8.
To lower the pump inside the sump secure the chain to
the special eye bolt cast on the head of the unit.
9.
Fit the coupling counter flange in the upper bracket and
lower the pump inside the sump, letting it slide along
the guiding tubes.
When it reaches the bottom, the pump will
automatically connect with the coupling foot.
10. Secure the chain and electrical cables to the upper
bracket, fit the electrical cables inside the special
guards between the well and the control panel.
Warning
Make sure that the cables are not bent or
pinched, to avoid undue wear or damage.
CHECK AND MAINTENANCE
Danger
WARNING!
fingers inside the suction inlet as there is
a risk of injuries due to contact with the
impeller. Keep in mind that the pump
may stop and restart automatically
following the triggering of thermal
protections or of remote control devices;
only the interruption of the mains supply
may eliminate this risk.
INSPECTIONS
Periodical checks and preventive maintenance ensure safer
operation for a longer period of time. The pump must be
inspected at least once a year and, in case of operations under
particularly stressful conditions, the inspections must be more
frequent. On these occasions remember to check the oil.
Under normal working conditions the pump should be
overhauled by a qualified mechanic every three years.
OIL CHANGE
The oil chamber is filled at the factory; if there are traces of water
or light emulsion the oil has to be changed. The pump must be
extracted from the sump. The oil plug is on the side of the oil
chamber; we suggest performing this operation at a shop.
Danger
- WARNING! If there is infiltration
through the seal the oil chamber may be
under pressure. To avoid sprays wrap a
rag around the oil tank screw when you
loosen it.
- Loosen the oil chamber plug and let all
the oil out, then refill using the prescribed
quantity of lubricant; tighten the plug,
remembering that the copper washer must
always be replaced.
- If you notice that the oil is emulsified or
that there are evident signs of water,
check the lower mechanical seal; replace
it if necessary or contact an authorized
dealer.
CLEANING

manufacturer so that accurate actions can
take place.
Make sure that the product and its components have been
thoroughly cleaned, before send the product to the manufacturer.
For clean impeller from filamentous materials, it can be sufficient
to start the pump for a few seconds, with opposite direction of
rotation.
If the pump is used only occasionally it should be cleaned after
each operation by flushing with clean water to eliminate deposits
and caking.
We recommend you periodically check the condition of the
automatic level switches, especially in fixed installations. By

pit are emptied. If any dirt deposits are found on the float switch
they must be removed.
After cleaning, the sump should be flushed with clean water. A
few start and stop cycles, with the selector switch in automatic
position, are recommended.
CHECKING
If the pump works but the delivery is inadequate check the
following:
•
the direction of the pump rotation. See "Direction of
rotation";
•
make sure the valves are open and intact;
•
make sure the tubes, impeller and filter are not
obstructed;
•
the impeller should rotate freely;
•
make sure that the head required by the plant has not
changed;
•
check for leaks in the pipes;
•
make sure the impeller is not worn.
Warning
10
Do not continuously try to start the
mixer if the thermal protection device
triggers.
