NOTE:
NOTE: The following procedure relieves all fluid and
air pressure in the system. Use your control interface
to issue the necessary commands to your system.
1.
Turn off the supply pumps. Open the drain valve
on the supply line fluid filter to relieve pressure
in the supply line.
2.
Command the system to Standby. From
Maintenance Screen 5 on the ADM, check the
box in the field labeled Gun for the color or
catalyst in the pump. Trigger the spray device to
relieve pressure. Repeat for each pump in the
system.
3.
Flush the remote mix manifold and spray device.
See
.
4.
Shut off the solvent supply pump. To relieve
pressure, command the system to Purge and
trigger the spray device. When the pressure is
relieved, command the system to Standby to
avoid getting a Purge Incomplete alarm.
5.
If pressure remains in the solvent line between
the solvent supply pump and the solvent valve:
• VERY SLOWLY loosen a fitting to relieve
pressure gradually.
• Loosen the fitting completely.

NOTE: The following procedure relieves all fluid and
air pressure in the system.
1.
Turn off the supply pumps. Open the drain valve
on the supply line fluid filter to relieve pressure in
the supply lines. Do this for each color.
If using an electrostatic gun, shut off the
electrostatics before flushing the gun.
2.
Trigger the gun to relieve pressure. From
Maintenance Screen 5 on the ADM, check the
box in the field labeled Gun for each color in the
system, to manually open each color valve.
3.
Set the system to Recipe 0 to flush the pumps
and to purge to the spray device. Hold the gun
trigger open after the solvent valve shuts off to
relieve all pressure. When flushing is complete
the system will go to Standby.
4.
Shut off the solvent supply pump. Set the system
to Recipe 0 to flush solvent from the pumps and
to purge to the spray device. Command the
system to Standby after just a couple of seconds,
to avoid getting a Purge Incomplete alarm.
5.
If pressure remains in the solvent line between
the solvent supply pump and the solvent valve:
• VERY SLOWLY loosen a fitting to relieve
pressure gradually.
• Loosen the fitting completely.
6.
Verify on the ADM Home Screen that neither
pump is showing any pressure.
