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 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 electric 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
extinguishers.
h
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
Ensure that all joints and couplings are locked correctly before starting the pump again
after repair work.
