Installation
* Includes mix chamber and cleanout tool.
† Extended wear life for abrasive materials.
‡ When used with mix chamber AR5252 at 1000 psi
(7.0 MPa, 70 bar).
1. Remove the existing air cap (round or flat) from the
Fusion Gun and replace it with the adapter (1).
Thread the adapter onto the mix chamber until it
bottoms out.
2. Insert the packing (2) through the center of the
adapter (1) with the stepped end facing the mix
chamber.
3. Place the stud wall tip (4) onto the packing (2) and
tighten the air cap (3) with light hand force.
4. Adjust the tip orientation with a standard 5/16 in. nut
driver (provided with gun). See F
IG. 2.
Cleaning Tips
1. If the pattern begins to shrink or becomes distorted,
relieve pressure (see your gun manual) and clean
the internal dome of the tip (4) with the tip cleanout
tool (15D234). See F
IG. 3.
2. Clean out the inside diameter of the packing (2) and
the flat mix chamber with a 0.94 in. (3/32 in, 2.39
mm) dia. drill bit (Graco cleanout tool kit 246624).
3. Add a thin layer of lubricant on the outside faces of
the air cap (3) to ease cleaning.
• This kit will not work with round mix chambers
(i.e. ARXXXX). If there is a round mix cham-
ber in the gun, replace it with a flat mix cham-
ber. Smaller flat mix chambers can be
ordered for lower fluid flow applications. See
Flat Mix Chamber Kit chart.
