Never operate the pump if it is not correctly installed and fixed. Doing so can cause serious
damage to the device and fittings.
WARNING
For correct operation of the pump unit and to ensure operator safety,
it is obligatory to fit devices designed to reduce the risk of injury by
fluid injection, splashing, etc.
1
The circuit MUST, OF NECESSITY, be equipped with bleed ball
valves upstream of the pump unit. These devices make it possible
to close stretches of line and discharge the compressed air trapped
in them. Trapped air can cause the pump to start suddenly and
unexpectedly, with the consequent risk of severe injuries.
7
The circuit MUST, OF NECESSITY, be equipped with a thermal
safety device downstream of the pump unit. The system makes it possible
to discharge hazardous excess pressure caused by the thermal expansion
of the fluid.
8
The circuit MUST, OF NECESSITY, be equipped with a drain
valve downstream of the pump unit, so as to allow the discharge of
fluid in order to reduce system pressure.
3
We recommend that you fit a pressure regulator with pressure gauge,
so that you can monitor pump speed and pressure with complete ease.
5
Running the pneumatic motor too fast can cause serious damage.
The presence of a safety valve ensures that the flow can be shut off if the
set pressure is exceeded.
4
For applications involving intensive use, we recommend that you fit
an automatic lubricator in the line so as to maximise the service life of the
pneumatic motor. Use only oil for pneumatic tools or SAE10 engine oil.
Set the lubricator to dispense a maximum of one drop every 10 minutes.
2
The presence of an air filter upstream of the pump unit helps remove
dirt and contaminants, thus extending the service life of the pneumatic
motor.
