System Operation
Purging Using Recipe 0
Recipe 0 is typically used:
• in multiple color systems to purge out material lines
without loading a new color
• at the end of a shift to prevent hardening of cata-
lyzed material.
To setup Recipe 0, go to Advanced Setup. Select the
Recipe tab and change the Recipe to 0. The Recipe 0
Setup Screen appears. Set the chop times from 0-999
seconds in increments of 1 second.
1. Press the Standby
Trigger the gun to relieve pressure.
If you are using a high pressure gun, engage the trig-
ger lock. Remove spray tip and clean tip separately.
If using an electrostatic gun shut off the electrostatics
before flushing the gun.
2. If using a gun flush box, place the gun into the box
and close the lid.
3. Select Recipe 0 and press Enter
4. If a gun flush box is not used, trigger
the gun into a grounded metal pail
until the purge sequence is com-
plete.
5. The color change LED blinks while Recipe 0 runs

Purging Fluid Supply System
Follow this procedure before:
• the first time material is loaded into equipment*
• servicing
• shutting down equipment for an extended period of
time
• putting equipment into storage
*
Some steps are not necessary for initial flushing,
as no material has been loaded into the system
yet.
1. Press the Standby
Trigger the gun to relieve pressure.
If you are using a high pressure gun, engage the trig-
ger lock. Remove spray tip and clean tip separately.
If using an electrostatic gun, shut off the electrostatics
before flushing the gun.
2. Attach solvent supply lines as follows:
• Single color/single catalyst systems: discon-
nect the component A and B fluid supplies at
the flow meter inlets, and connect regulated sol-
vent supply lines.
• Multiple color/single catalyst systems: dis-
connect only the component B fluid supply at
the flow meter inlet and connect a regulated sol-
vent supply line.
• Multiple color/multiple catalyst systems:
connect the solvent supply lines to the desig-
nated solvent valve on the color and catalyst
valve stacks. Do not connect a solvent supply to
either flow meter.
