Operation
4.
Increase the air inlet pressure for a short time by about 10% above the
maximum permissible value. The safety valve must blow off.
5.
Regulate the air pressure regulator for the pump fully back.
5.1.2 Flushing residues of the test medium
After assembly, this unit was factory tested for flawless function by means of
a test substance. The unit must be flushed with a flushing agent during initial
commissioning so that the material to be sprayed is not affected by the test
medium.
1.
Remove the nozzle from the spray gun.
2.
Unscrew the follow plate.
Take care that the seal between the follow plate
and the pump is not lost.
3.
Regulate a pressure of 1.5 - 2 bar on the air pres-
sure regulator for the ram.
4.
Set the ram control lever to position “Up”, to move
the ram with the pump up.
Fig. 12: Ram control lever
5.
Once there is sufficient space under the pump for the flushing agent
container, set the ram control lever to “Stop” (middle position as shown
in Fig. 12).
6.
Place a drum with with 10-15 l flush
-
ing agent below the pump.
7.
Set the ram control lever to position
“Down” an move the ram down until
the suction of the pump immersed into
the flushing agent.
8.
Hold the drain hose into the collecting
vessel (see Fig. 13).
9.
Open the drain ball valve.

10.
Regulate the air inlet pressure on the air pressure regulator for the pump so
that the pump runs slowly.
11.
Allow the flushing agent, soiled with the test medium, to run out of the drain
hose into the collecting vessel for at least 10 seconds.
12.
Close the drain ball valve.
13.
Hold the spray gun into the collecting vessel.
14.
Unlock the spray gun and spray for a minimum of 10 seconds against the
inner wall of the container. We recommend a cleaning period of approx.
one minute for a good cleaning result.
WARNING
Heating up flushing agents can cause an explosion. This may result in seri
-
ous injury to persons and damage to property.
➤
In order to avoid the danger of explosion caused by heating up the flush
-
ing agent, it must not be pumped longer than 5 minutes.
