10. Purge air from the fluid lines.
a. Shut off air to the gun by clos-
ing the air regulator or shutoff
valve for the gun atomizing air.
b. Trigger the gun (man-
ual or automatic) into
a grounded metal pail.
c. Go to Mix mode.
d. If the flow meters over-run because of air in the
system, an alarm will occur and operation stops.
Press the Alarm Reset
key to clear
alarm.
e. Go to Mix mode.
11. Adjust the flow rate.
The fluid flow rate is shown on the EasyKey Status
screen. The fluid supply lines on the screen high-
light when the dose valve is open.
Watch the fluid flow rate displayed on the Status
screen while the gun is fully open.
If the fluid flow rate is too low: increase air pres-
sure to the fluid supply or increase the regulated
fluid pressure.
If the fluid flow rate is too high: reduce the air
pressure, close the fluid manifold dose valves fur-
ther, or adjust the fluid pressure regulator.
NOTE: Pressure adjustments of each component will
vary with fluid viscosity. Adjust as needed.
12. Turn on atomizing air to the gun. Check the spray
pattern as instructed in your spray gun manual.
NOTE: Do not allow a fluid supply tank to run empty. It is
possible for air flow in the supply line to turn gear meters
in the same manner as fluid. This can lead to the mixing
of fluid and air that meets the ratio and tolerance set-
tings of the equipment.
