To avoid fire and explosion, always ground
equipment and waste container. To avoid static
sparking and injury from splashing, always flush at
the lowest possible pressure.
There are times when you only want to purge the
remote mix manifold and the spray device, such as:
• end of potlife
• breaks in spraying that exceed the potlife
• overnight shutdown or end of shift
• before servicing the remote mix manifold, hose or
gun.
1.
Command the Mix Unit to Standby.
2.
If you are using a high pressure spray device or
an electrostatic gun, shut off the atomizing air.
3.
To reduce the risk fire and explosion, shut off
electrostatics before flushing the gun.
If using an electrostatic gun, shut off the
electrostatics before flushing the gun.
4.
Command the Mix Unit to Purge A,
Purge B, or Recipe Purge. (See
.) Trigger the
spray device into a grounded metal pail until
the purge sequence is complete. When done
purging, the Mix Unit automatically switches to
Standby mode, signalling the spray device to
stop spraying.
5.
If the Mix Unit is not completely clean, repeat
Step 5.
NOTE:
NOTE:
NOTE: For optimal efficiency, adjust purge
sequence times so only one cycle is required.
NOTE:
NOTE:
NOTE: The remote mix manifold and gun remain full
of solvent after purging.

Follow this procedure before:
• the first time material is loaded into the equipment
• servicing
• shutting down equipment for an extended period
of time
• putting equipment into storage

1.
Relieve the pressure.
See
Pressure Relief Procedure, page 19
2.
Disconnect the color and catalyst supply lines
from the pump inlet manifolds, and connect
regulated solvent supply lines.
3.
Set the solvent supply pressure regulator at the
lowest pressure possible. Generally a setting
of 25–50 psi (0.18–0.35 MPa, 1.8–3.5 bar) is
sufficient.
4.
Enable manual override on
.
5.
On the ADM, go to the Fill screen for Mix Unit
#1. Set the Material to Color (A). Press
.
The system will pump solvent through pump A
all the way to the gun.
6.
Hold a metal part of the spray device firmly to a
grounded metal pail. Trigger the spray device
until clean solvent dispenses.
7.
On the ADM, go to the Fill screen for Mix Unit
#1. Set the Material to Catalyst (B). Press
.
The system will pump solvent through pump B
all the way to the gun.
8.
Relieve the pressure.
