PEM-CG3 Start up and Working
3. Working with the spray guns
3.1 Starting up the spray gun
•
Switch on the control unit, actuate the trigger on the spray gun and set the compressed air
supply at
29 psi (2 bar).
•
Adjust the high voltage at the control unit.
•
Check at the control unit whether the atomizing air is opened on actuating the trigger. As a
result the deflector cone remains free from powder deposits and the cascade chamber is
flushed.
•
Fill the powder container to max. 75% of its capacity with powder, but do not close the
cup yet.

•
Open the fluid air supply slowly with the green setting
knob L until the powder is fluidized.
•
The powder should be simmering slightly.
•
Close the powder container tightly.
•
Hold the manual spray gun in the spray booth and
actuate the trigger on the manual spray gun.
•
Open the red setting knob K to provide a feed air sup-
ply relative to the desired powder throughput.
3.2 Switching off the spray gun
Hint
On each interruption to work, the spray gun should be blown through (purged) and
powder residue removed. In this way
powder deposits and a surge the next time the
spray gun is switched on can be largely avoided.
