Complete cleaning
Static charges can cause sparks which can lead to fire and explosions.
Due to possible electrostatic charge, DO NOT use narrow neck cans or drums with bung-
holes. With metallic containers, take care that the spray gun* is constantly in contact with
the container wall.
Pressure values listed in this chapter are only
guideline values
and eventually have to
be adjusted according to the
viscosity of the material
or the
hose length being used
.
While working, observe if you have to adapt the pressure to get the desired result.
All position numbers found in this chapter apply to the specification in the chapter 3.6
“Component description”.
Task: When work on the machine is stopped for a long time, the entire system
should be cleaned (mixer to spray gun*, as well as material container to mixer).
Initial situation:
➤
Perform all steps in chapter “Pause in work and end of work”.
➤
The unit is now flushed from mixer to the spray gun*. In the next steps the area from
the material container to the mixer gets flushed.
➤
All equipment for preparation of the material (heaters and/or agitators) are turned off,
and they are disconnected from the power supply!
When thinner evaporates, explosive gases may occur, which could ignite on hot
surfaces.
Turn off all equipment for heating up the material and wait until the system cool down!!
Note:
A faster cool down can be achieved by letting the material circulate in the system
(max. 20 minutes). All equipment for heating up the material must be turned off.
Make sure that the viscosity of the material allows circulation when not heated by check-
ing the specification stated by the manufacturer of the material.
Cleaning from material container to the mixer
➤
Make sure that the air regulator (pos. 2.2) of the main pump is completely turned off and
the ball valve (pos. 2.1) is closed.
➤
Make also sure that all air regulators of the feed pumps (pos. 10.1) are turned off.
➤
Hold the return hoses (pos. 9) into separate empty containers.
➤
Secure the return hoses in the appropriate supply containers.
CAUTION!
The flush pump has to
be ready at all times
during the working
process.
At all times it must be
possible to flush com-
ponents, which were
contaminated by mixed
material,
within the
given pot life
!
