Operation
5.2.4
Intermediate flushing
1.
Regulate the air inlet pressure of the pump completely back.
2.
Set the ram control lever to “Stop”.
3.
Open the compressed air shut-off valve for the container ventilation.
4.
Set the ram control lever to position “Up”, to move the ram up.
5.
Once the sealing lip of the follow plate reaches the top of the material drum,
close the compressed air shut-off valve for the container ventilation.
6.
Once there is sufficient space for removing the material drum, set the ram
control lever to position “Stop”.
7.
Remove the material drum.
8.
Unscrew the follow plate.
Take care that the seal between the follow plate and the pump is not lost.
9.
Clean the follow plate thoroughly.
The black rubber seal is not solvent resistant. Do not soak in solvent, but
only wipe the seal clean.
10.
Place a drum with with 10-15 l flushing agent below the pump.
11.
Set the ram control lever to position “Down” an move the ram down until the
suction of the pump immersed into the flushing agent.
12.
Hold the drain hose into the collecting vessel.
13.
Open the drain ball valve.
14.
Regulate the air inlet pressure on the air pressure regulator for the pump so
that the pump runs slowly.
Do not trigger the spray gun during the intermediate flushing to prevent mix
-
ing of the solvent with the material in the spray hose.
15.
Allow the pump to run until the solvent runs out of the drain hose.
16.
Hold the drain hose into the flushing agent drum and allow the unit to run
for 2-3 minutes, so that all remaining material is flushed out of the unit.
17.
Move the ram up.
18.
Remove the flushing agent drum.
19.
Screw on the follow plate with seal.
20.
Place the (new) material container under the pump and fill the pump with
material. Collect the remaining solvent that exits the drain hose, in a con-
tainer for waste material.
21.
Close the drain valve again as soon as the processing material exits the
drain hose.
22.
Proceed with coating work.
