Operation
8.
Close the compressed air shut-off valve on the maintenance unit.
9.
Only for version with material heaters:
Regulate the temperature controller on material flow heaters, drum floor
heaters or hose heaters completely back.
10.
Only for version with feed pumps:
Regulate the air pressure regulators for the feed pumps fully back and
close the ball valves on the feed hoses.
11.
Operate the spray gun once again for a moment to relieve any flushing
pressure residues, so that the entire unit has been relieved.
5.6 Complete cleaning
During initial commissioning, material change and decommissioning for a lon-
ger period, the unit must be cleaned completely.
1.
Perform all work steps as described in chapter 5.3, in order to clean the
section between mixing unit and spray gun.
2.
Regulate the air pressure regulator for the flushing pump fully back.
3.
Operate the spray gun once again for a moment to relieve the flushing
pressure completely.
Perform the following work steps to clean the section between material inlet
and mixing unit.
Both components must be strictly kept separated, also during cleaning. Use
a separate solvent and collecting container for each component to avoid
material reactions and thus possible damage to the unit.
WARNING
Explosive gases may be generated by the evaporation of flushing agent,
which may ignite on hot heat sources.
➤
Before you start cleaning work you must switch off all material heaters
and allow the unit to cool down. Quicker cooling can be achieved by
circulating the material through the unit (max. 20 minutes).
4.
Guide the return flow hoses into separate collecting vessels and secure
them against accidental slipping out.
5.
Connect the flushing agent feed:
➤
For units with suction system place the suction pipes of the material
pumps into the drum with flushing agent belonging to the material.
➤
For units with feed drums drain the material off through the drain valves,
then fill in the flushing agent belonging to the material.
➤
For units with feed pumps insert their suction pipes into the flushing
agent belonging to the material, open the ball valves and set the air
pressure regulators on the feed pumps to a pressure of approx. 2 - 3 bar.
6.
Set the levers at the mixing unit to “Circulate“.
7.
Regulate the air pressure regulator of the main pump so that the main
pump runs slowly.
8.
Close the return flow as soon as clean flushing agent starts to run out of
the return flow hoses.
