Operation
5.7 Cleaning the machine completely
A complete cleaning of the machine is necessary:
➤
during the initial commissioning so that the spraying material is not
influenced by the test substance with which the machine was tested for
correct operation in the factory.
➤
during a change of the material.
➤
if the machine is to be deactivated for a longer period.
1.
Interrupt work according to chap. 5.5 on page 28.
Complete the following work steps to clean the area from the material inlet to
the mixing unit.
Both components must also be kept strictly separate during cleaning.
Use a separate material drum and collecting vessel for each component to
prevent material reactions and damage to the machine.
2.
Relieve the pressure in the machine according to 5.6 on page 28.
3.
Stop the material supply:
➤
For proportioning pumps that are supplied with material via a suction
hose, take the material suction hoses for both components out of the
material drums and strip the material located therein into the associated
container.
➤
For proportioning pumps that are supplied with material via hoppers,
pump any existing material completely out of the hoppers and remove
the material residues with a cloth.
4.
Connect the cleaning agent supply:
➤
For proportioning pumps that are supplied with material via a suction
hose, place each material suction hose into a separate container with
the cleaning agent associated with the material.
➤
For proportioning pumps that are supplied with material via a hopper, fill
the cleaning agent associated with the material into each hopper.
5.
Open the compressed air shut-off valve.
6.
Hold the mixing unit, directing the material ejection against the inner wall of
the collecting vessel.
7.
Set the one-hand lever of the mixing unit to "Injection".
8.
Set a low air inlet pressure on the compressed air regulator for the
proportioning pumps.
9.
Set the one-hand lever of the mixing unit to "Stop" as soon as clean
flushing agent runs out.
10.
Turn the compressed air supply for the proportioning pumps down
completely.
11.
Close the compressed air shut-off valve.
12.
Relieve the pressure in the material lines by briefly opening and closing the
one-hand lever on the mixer block.
