Eyes:

Rinse immediately with running water for 15
minutes keeping eyelids wide open. Contact an
eye doctor.
Skin:

Remove the contaminated clothing, wash skin
with soap and water; if necessary, consult a
doctor.
FOLLOW ALL THE OTHER HYGIENIC AND SAFETY
PRACTICES AND
REGULATIONS.
HOISTING EQUIPMENT
Suitable hoisting equipment is necessary for lifting the
mixer and lowering it inside the tank, if possible without
requiring a take-up. The minimum distance between the
lifting hook and the edge of the tank must be like show to
pages 26-33 to allow for the extraction of the mixer from
the tank. Oversized hoisting equipment may cause damage
to the mixer in the event that it should get jammed during
the lifting operations. Make sure that the lifting equipment
is properly secured.
Danger WARNING! Keep clear of suspended loads.

ELECTRICAL CONNECTIONS

The entire electric system must be installed by skilled
personnel. Follow local rules and regulations. The
manufacturer does not assume any responsibility in case of
services carried on by not authorized personnel.
Danger If the cable must be replaced, for safety reasons, the earth conductor
Risk of electric
shock
(yellow-green) must be about 50mm
longer than the phase conductors.
In the event that the cable should
accidentally come loose, the earth
terminal must be the last one to be
disconnected. The command and
control equipment cannot be installed
inside the sump pit.
Remember that the initial input current for direct starting
may be up to 6 times the rated absorption; therefore, make
sure that the fuses or the automatic switches have the
adequate setting.
Warning - Any splicing of the supply cable
must be absolutely waterproof.
- Make sure that the mains voltage
and frequency correspond with the
mixer rating.
- The supply voltage must agree with
the specifications indicated on the
rating plate, with a 10% tolerance.
- Always check the current absorbed
by the mixer.
- Make sure that the setting of the
temperature relay does not exceed the
indicated value pag 3.
LOCAL RULES AND
ELECTRIC MOTOR
Motor asynchronous squirrel cage type, insulation class H
(180°C). Dry motor, cooled by surrounding liquid.
Protection degree IP 68.
The motor is designed for continuous or intermittent
operation, with a maximum of 15 starts per hour at regular
intervals.
The motor is designed for work with 5% maximum
voltage unbalance between the phases (in compliance with
norms CEI EN 60034-1).
DIRECTION OF ROTATION
The direction of rotation must be carefully checked when
the mixer are started.
Warning If the direction of rotation is wrong
the
inadequate and may result in
damage to the unit.
The direction of rotation is correct if, at starting, you
notice an clockwise recoil when looking at the mixer from
the cable gland side. If the direction of rotation is wrong
you need to invert any 2 of the 3 phase wires on the
terminal board of the electrical box.

shock
Take good care of the supply cable; replace it immediately
if damaged.
Warning The end of the cable must not be
submerged. The cable terminals must
be securely fastened above the
maximum level of the liquid, to
prevent the water from penetrating
inside the motor through the cable.
ELECTRICAL PANEL
Danger Do not connect the pump directly
by a plug; connect the electric cable

to a control box with thermal
protection.
This series of submersible pumps must be equipped with
an electrical control panel. The panel must be designed to
allow both manual and automatic operation. It should be
equipped with at least a low voltage control circuit, an
automatic level control an adjustment circuit, a circuit for
detecting any operating anomalies. If required the
complete control panel can be supplied.
