Operation
6.
Close the return flow as soon as clean flushing agent starts to run out of
the return flow hoses.
7.
Replace the contaminated flushing agent in the feed tanks with fresh flush-
ing agent
8.
Open the return flow again and allow the flushing agent to circulate through
the machine for approx. 3 - 7 minutes, depending on the length of the mate-
rial hoses.
9.
Set the levers at the mixing unit to “Spray“.
10.
Trigger the spray gun, until clean flushing agent starts to run out.
11.
Set the levers at the mixing unit again to “Circulation“.
12.
Regulate the compressed air pressure regulator for the proportioning pump
fully back.
13.
Close the compressed air shut-off valve on the maintenance unit.
14.
Once both pressure gauges on the high pressure filters show 0 bar, close
the return ball valves at the mixing unit.
15.
Drain the flushing agent off the feed tanks through the drain valves.
The machine is now fully cleaned and pressure-relieved and thus prepared for
a prolonged decommissioning.
5.6 Material change
The machine has been specially configured for your application case. It is
necessary to check compatibility of the materials used with other materials in
each individual case.
WIWA
shall be happy to assist you in determining the
suitability of your machine for other materials.
5.7 Decommissioning
For a decommissioning, flush the unit, perform a pressure release and switch
off the unit.
1.
Set the levers at the mixing unit to “Circulation“.
2.
Switch off the material flow heaters using the main switch.
3.
Regulate the speed of rotation for the agitator in the A component feed tank
with the adjusting screw on the air intake of the agitator fully back.
4.
Regulate the compressed air pressure regulator for the proportioning pump
fully back.
5.
Trigger the spray gun, until the material pressure has been fully relieved.
6.
Flush the machine as described in chapter 5.3 on page 33.
7.
Regulate the compressed air pressure regulator for the flushing pump fully
back.
8.
Close the compressed air shut-off valve on the maintenance unit.
9.
Trigger the spray gun once again for a moment to relieve any flushing pres-
sure residues, so that the entire unit has been relieved.
