TEST AND CHECKOUT
PROCEDURE FOR COLOR
CHANGER
Step 1:
1. Connect air line to a regulated air supply.
2. Attach the air line to a ball valve assembled to
the outlet of the color changer.
3. Adjust the air supply pressure to 100 psi (6.9
bar).
4. Open the ball valve at the outlet of the color
changer.
5. Apply a soap solution on the color changer
manifold.
6. Check the manifold assembly’s mating sur-
faces between color blocks for soap bubbles.
7. If no bubbles are present, rinse manifold with
water and blow dry with air.
Step 2:
1. Attach two (2) regulated air supply hoses, one
with a 3-way valve (normally closed) for operating
the color valve cylinder on the color changer. (Set
the pressure to the 3-way valve at 75 psi
(5.8 bar) or more.)
The second hose will be used for supplying 100 psi
(6.9 bar) of air to the color inlet port of each color
changer valve.
2. Connect the air supply hose with 100 psi
(6.9 bar) to color inlet valve. Connect a 2-way ball
valve to the matching return port on the color
changer manifold.
3. Turn the ball valve installed on the paint circu-
lation fitting to verify recirculation ability.
