4. INSTALLATION
4.6 • COUPLING GUARD ASSEMBLY
After the coupling alignment, assembly coupling guard by tightening
relevant screws. (Fig.16)
ATTENTION!
The pump unit must not be run without guards covering
all rotating shafts & coupling.
4.7 • LUBRICATION
Bearings lubricated by grease.
These bearings are supplied already greased.
Bearings lubricated by oil.
Support must be filled in with one of the following type of oil:
- AGIP: ACER 46
- MOBIL D.T.E. Oil Medium
OIL FILLING
Remove oil filler/breather plug from top of bearing housing and fill
with oil to mark on level indicator (Fig.29)
Ensure that oil level has stabilized, then re-fit oil filler/
breather. Repeat above for bearing housing at other end of
pump.
4.8 • ELECTRICAL SYSTEM
ATTENTION!
Motor connection and its related electrical system has to be ex-
ecuted by a skilled and qualified electrician in accordance with
the electrical normes in force.
Any connecting interventions must be performed without electric
voltage.
Please check that the voltage corresponds to that reported on the mo-
tor label.
The power supply cable must be sized according to the motor input and
to the cable length (ref. pump metallic label).
THREEPHASE MOTORS
We suggest a star delta starting for motor with power higher than
7,5 Kw.
Check the kind of connection reported on the motor label.
This connection varies depending on the motor winding and voltage.
Verify that terminals of the electric box are connected as per correct
table.(Fig.30)
ATTENTION!
Always carry out the grounding. The body of the motor must be grounded
with the suitable connections.
Check insulation before starting.
The motor shall be always protected against averloads by a magneto-
thermo breaker, positioned before the main switch, and set at a breaking
current not higher that 1,15 the nominal motor current.
It is technicial's responsibility to carry out final electrical tests in
compliance with the regulations and to issue a Certificate of Conformity
for the electrical installation.
