WARNING! Periodic control must be made to ensure that there is no powder and/or deposits
on the external and internal surfaces of the pump. They must be cleaned with a damp cloth, if
necessary.
WARNING! Removal of the silencer and the air supply fitting must be done when the pump is
free of powder. Before restarting the pump, ensure that no powder has entered the pneumatic
distributor.
To replace worn parts, use only genuine spare parts.
Failure to comply with the above may increase the risks of injuries to the operator, technicians,
persons and damages to the pump and/or the environment that cannot be ascribed to the
manufacturer.
However five general elements are important:
A.
all the operations must be carried out by skilled personnel or monitored by qualified personnel as
appropriate
B.
implement personal protection works (when the pump is installed in places with high human traffic)
against splashes of fluorescent fluid in case of accidental breakage and always direct possible leakages
towards collection tanks
C.
wear appropriate Protective Person Equipment (PPE) when operating on the pump
D.
make sure that the intake and discharge valves are correctly closed during the disassembly
E.
make sure that no air is supplied to the pneumatic circuit and discharge the residual air from the
pneumatic circuit during disassembly
It is very important to recognize systems with well arranged, identifiable piping, suitably
equipped shut-off valves and comfortable compartments and passages for operators who
must inspect the pump (since the pressure developed by the pump may promote failures in
the system if it is defective or worn).
WARNING! Raised temperature can cause damage on the pump and/or piping and may also
be hazardous for personnel in the vicinity of the pump/piping. Avoid quick temperature
changes and do not exceed the maximum temperature specified. The pump should not
