ENDING WORK
When storing the device for longer periods of time, it is necessary to thoroughly clean it
and protect it from corrosion. Use a suitable preserving fl uid, according to the material of
the wetted parts of the pump.
Suctioning:
Make sure that the air pressure regulator knob is turned fully counterclockwise
(0 bar pressure).
Open the compressed air and material delivery valve, then increase the air pressure until
the pump starts. Don't let the pump run too quickly while suctioning.
Return valve (if installed):
To facilitate the suctioning of the pump, open the return valve.
The return valve is strongly recommended in case of viscous materials or long pipes. Close
the return valve when the suctioning has fi nished.
Material delivery:
The pump supplies the material while the material delivery valve is open.
Change the air pressure with the air pressure regulator, in order to achieve the desired
amount or material pressure.
Drawn in air:
In case air accidentally fl ows into the pump suction inlet, the air pressure must immediately
be reduced to avoid the pump working at an excessive speed.
Stopping the pump:
To stop the pump, simply close the material delivery valve or any other device (such as
dispensing valves or guns) installed on the delivery line.
When the work is completed, close the air cut-off valve. Relieve the pressure in the material
line, by opening the return valve (if installed) or the dispensing device (valve or spray gun).
Dealing with hardening liquids:
In case of hardening liquids such as 2-component mixed resins, the pump, and anything
connected to it, must be thoroughly fl ushed out at the end of the working session by
using a solvent suitable for the type of resin being used. The solvent must be left inside the
pump, until its next use.
