Warning Notes
a
Death may result from contact with high voltages. Always take
extreme care and observe the accident prevention regulations in
force.
b
Always disconnect the power supply to the pump before
maintenance work. Place a special warning signs over the power
supply breaker switch: MACHINE UNDERGOING
MAINTENANCE - DO NOT POWER ON.
c
If you are performing maintenance after the pump has been
operating for a considerable time, allow sufficient time for it to
cool down as the external surface temperature may be in excess
of 60 °C.
d
Failure to provide the pump with an earth connection may cause
serious damage to operators. Always ensure that there is an earth
connection and that it complies with the standards.
e
When cleaning the pump and its component parts, avoid the use
of flammable or toxic solvents, such as benzin, benzol, ether or
alcohol. The recommendation is to use a soap and water solution,
preferably in ultrasound washing machines, taking care to dry all
the cleaned parts at temperatures under 100 °C in order to
eliminate residual moisture.
f
Prolonged overloads or breakdowns may cause the electrical
motor to overheat, and to release noxious smoke; remove the
power immediately as a precaution and do not approach the
pump at least until you have provided ventilation to drive out the
smoke. Take care not to breathe in the fumes remaining inside
the pump in the course of repair work.
g
In case of fire, do not throw water on the pump. Switch the
power off and use CO

Carefully inspect the flanges to ensure that there is no dust, oil,
dirt or defects of the mating surfaces, before making the required
connections.
i
Do not wear any objects that may become entangled in the
mechanisms and/or act as conductors (chains, bracelets, etc.).
