WARNING!
To ensure short-circuit or overload protection, an
automatic circuit breaker of appropriate capacity
must be installed on the main power line towards
the pump. The capacity of the switch must be
compatible with the rating plate data of the motor
actually installed and must be chosen by the in-
staller. Connect by adopting all the current appli-
cable rules and regulations.
CAUTION!
Fill the pump with lubricating oil before starting it.
The pump is supplied empty.
WARNING!
Take out the protective caps on the suction and
exhaust flanges before doing anything else. In the
event of an accidental start-up, the air inside the
pump could violently expel the protective caps and
harm the operator.
WARNING!
During installation, pay maximum attention that the
suction flange is connected to the vacuum cham-
ber and the exhaust flange is not closed (see fig-
ures below).
Be very careful not to invert exhaust and suction.
Maximum pressure inside the oil container must
not exceed 1.5 bar (abs.)
Non-observance of these precautions may be dan-
gerous for the pump and the operator.

CAUTION!
Check that your electrical mains voltage corre-
sponds to the range indicated on motor label.
Connect the pump to the power supply.
USE
There are no special procedures for switching the pump
on. Simply connect to the electrical power supply to start
it running.
Refer to the wiring diagram supplied with the pump for
correct connection.
WARNING!
The pump is designed for operation with neutral or
non-corrosive fluids. It is absolutely forbidden to
use potentially explosive or flammable substances.
CAUTION!
In three-phase motors, reversing the phase will re-
verse the sense of rotation of the pump. This may
cause mechanical damage.
MAINTENANCE
Personnel responsible for pump operation and
maintenance must be well-trained and must be
aware of the accident prevention rules.
WARNING!
Death may result from contact with high voltages.
Always take extreme care and observe the acci-
dent prevention regulations in force.
WARNING!
When machine is powered take care on account of
moving parts and high voltages.
