HAZARD
Check the connection of the intake and discharge system of the pump to ensure that fluids, gases
or vapours processed do not contaminate the working environment and atmosphere surrounding
the pump.
WARNING
Always install an intake filter, especially if the pump is to work with air that might contain foreign
matters.
Pump outlet gases must be treated in such a way that they do not contaminate the working environment and the
surrounding atmosphere. If condensable vapours are pumped in, the discharge hose should be routed downwards
and have no bends to prevent the condensate produced in the discharge line from building up or flowing back into
the pump.
Never use friction hoses with hose diameters smaller than the intake diameter. Avoid exceeding hose lengths, tight
bends or bends spaced too closely together.
HAZARD
Do not insert outlet fitting pipes or devices that block or impede the disposal of outlet gases (max
overpressure exhaust 0.3 bar).

WIRING
WARNING
Check that network voltage and frequency correspond to values contained on the motor rating
plate.
The connection cable must be adequate for the power absorbed by the pump (absorption values are shown on the
pump motor rating plate) taking into account the environmental conditions of operation.
HAZARD
Always perform earthing of the electric motor and the pump (see 3.3, "Dimensions and
Characteristics" of this manual).
Always install a security system between the pump and the electric power supply. Pump absorption values are
shown on the motor rating plate.

Version (standard):
The pump comes complete with power cable and start/stop switch. The pump comes
complete with power cable and start/stop switch. The operator should install a plug and connect to an electrical
panel provided with electric protection.

~
and OEM Version:
Pump wiring must be connected inside the motor terminal board. See the wiring diagram
inside the terminal board or on motor rating plate. Install an electric protection system.
WARNING
Check that the direction of rotation is correct before starting the pump for the first time or after
changing the electrical connections.
The correct direction of rotation is indicated by the arrow on the pump (see 3.3 “Dimensions and
characteristics” of this manual). Pump operation with a rotation direction that is opposite to that
indicated can severely damage the pump itself.
