LED and the recipe display on the booth control
will blink during the mix fill. If the gun is loaded
with one recipe (G-xx) and the pumps with
another (P-xx), the display will alternate between
the two recipes. When the mix fill is completed,
the display will show R-xx, and the system will
go into Standby Mode.
NOTE: The system will automatically run a Mix

LED will turn on solid to indicate the system is
mixing. Adjust the flow rate by changing the
target pressure. The fluid flow rate shown on the
Spray screen is the combined total of component
A and B out of the gun.
• If the fluid flow rate is too low: increase the
spray pressure setting on the Spray screen or
booth control.
• If the fluid flow rate is too high: decrease the
spray pressure setting on the Spray screen or
booth control.
NOTE: If spray pressure is adjusted at the ADM
or booth control while spraying, it is not saved in
the recipe until the system is put in Standby. This
changes the pressure in the desired recipe.
4. Turn on atomizing air to the gun. Check the spray
pattern as instructed in your spray gun manual.
NOTE: Do not use the first 4-5 oz. (120-150 cc)
of material as it may not be thoroughly mixed due
to errors while priming the system. The Spray LED
must be on.
NOTICE
Do not allow a fluid supply tank to run empty.
This can damage the pumps and lead to the
proportioning of fluid and air that meets the ratio
and tolerance settings of the equipment. This can
further result in spraying uncatalyzed or poorly
catalyzed material.
