3. Adjust the flow rate. The fluid flow rate shown on the
Display Module screen is for either component A or
B, depending on which dose valve is open.
.
If the fluid flow rate is too low: increase air pres-
sure to component A and B fluid supplies or
increase the regulated fluid pressure of mixed
material.
If the fluid flow rate is too high: reduce the air
pressure to component A and B fluid supplies,
close the dose valves further, or decrease the reg-
ulated fluid pressure of mixed material.
4. Turn on atomizing air to the gun. Check the spray
pattern as instructed in your spray gun manual.
NOTE:
• Pressure adjustments of each component will vary
with fluid viscosity. Start with the same fluid pres-
sure for component A and B, then adjust as needed.
• 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.
Purging
NOTE: See Run Mode Details, pages 42-43, for further
screen information, if needed.
Purge the system:
• at the end of potlife
• breaks in spraying that exceed the potlife
• overnight shutdown or end of shift
• the first time material is loaded into equipment
• servicing
• shutting down equipment for an extended period of
time
1. Press on Run Mix Spray (Screen 2) or
from any screen to put the system in Standby.
2. Trigger the gun to relieve pressure.
3. If you are using a high pressure gun, engage the
trigger lock. Remove spray tip and clean tip sepa-
rately.
4. If using an electrostatic gun shut off the electrostat-
ics before flushing the gun.
5. Set the solvent supply pressure regulator at a pres-
sure high enough to completely purge the system in
a reasonable amount of time but low enough to
avoid splashing or an injection injury. Generally, a
setting of 100 psi (0.7 MPa, 7 bar) is sufficient.
6. If using a gun flush box, place the gun into the box
and close the lid.
7. Press on Run Mix Spray (Screen 2). The
purge sequence automatically starts.
If the gun flush box is not used, trig-
ger the gun into a grounded metal
pail until the purge sequence is com-
plete.
When done purging, the system automatically
switches to Standby mode.

NOTICE
Do not allow a fluid supply tank to run empty. It is pos-
sible for air flow in the supply line to turn gear meters
in the same manner as fluid. This can damage the
meters 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.
