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. Go to Standby mode (remove Mix input).
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 (manual or automatic) into a
grounded metal pail until the purge
sequence is complete.
5. The color change LED blinks while Recipe 0 runs
and turns solid after purge sequence is complete.
6. If the system is not completely clean, you can
repeat Recipe 0 by pressing Enter

Some steps are not necessary for initial flush-
ing, as no material has been loaded into the
system yet.
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.
