With the help of a plumb line make sure that the
guiding tubes is vertical.
2. Position the coupling foot at the bottom of the
sump in such a way that the tapered projection on
which the guiding tube will fit is plumb and in
line with the upper bracket.
Mark the fastening holes for the expansion bolts,
remove the foot and drill 4 holes, insert the bolts
and rest the foot on them.
Position the guiding tubes on the special tapered
projection on the foot and determine its final
length.
3. For wells that are more than 6 m deep,
intermediate brackets are necessary for the joining
of the guiding tubes.
4. Position the guiding tubes between the tapered
projection of the foot and that of the upper
bracket; again make sure that the tube is perfectly
vertical.
5. Fasten the coupling foot using plain washers and
nuts; insert the upper bracket inside the guiding
tubes making sure that there is no verticals lack
and fasten it.
6. Connect the delivery pipe to the coupling foot
using a plain gasket and screws.
7. Insert

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! Never introduce your
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 after 2000 working hours (see page 13
"MAINTENANCE PROGRAM") or 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.

coupling
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
LUBRICATION
The pump is supplied with lubricated ball bearings and is
ready for installations. Ball bearings must be periodically
lubricated by lithium soap grease, each 2000 functioning
hours, anyway once per year. The periodical ball bearings
lubrication must be insert into the maintenance program
(see page 13 "MAINTENANCE PROGRAM").
The pump is supplied with suitable spring greasers. For
grease replacement, disassemble filler and drainer cups
with relative washers.
Assemble the suitable greasers, so inject grease by a grease
gun. The replacement is finished when from the drainer
cup hole cames out clean grease. Once replaced the grease,
disassemble greasers and assemble cups.
Warning! Seals washers must be always substituted.

CLEANING

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 activating the selector switch (manual
position) the tank or sump 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

wrap a rag around the oil tank screw

all the oil out, then refill using the
prescribed quantity of lubricant (see
