3. Connect a 1/4 in. (6 mm) OD air supply line between
the 2KS air manifold and the 3KS air inlet elbow.
NOTICE
Use separate air supply lines for the following two
connections to avoid contaminating the purge air line
with fluid if the air purge valve and a check valve
failed.
4. Connect a clean air supply line to the shutoff valve.
This air line supplies air to operate the gun, sole-
noids, and dispense valves.
NOTE: See Technical Data on page 43 for additional
air supply/consumption information.

valve inlet on the 2KS Wall Mount Fluid Station.
6. Connect the air purge valve tubing (supplied) to a
clean, dry air supply (install filters/dryers as

The ProMix potlife timer will not function properly
when used with multiple guns operating simultane-
ously. To avoid having mixed material set in the equip-
ment, carefully monitor potlife by some other means.
If using a Graco electrostatic PRO
valve must be installed in the gun air line to shutoff the
atomizing and turbine air to the gun. Contact your
Graco distributor for information on air shutoff valves
for electrostatic applications.
