Ransburg MCV2 Modular Color Changer A10800-XX_A11077-XX - Manual (Page 30)

> NEVER wrap the equipment in plastic to
keep it clean. A surface charge may build-up
on the plastic surface and discharge to the
nearest grounded object. Efficiency of the
equipment will also be reduced and damage
or failure of the equipment’s components may
occur. WRAPPING THE EQUIPMENT in plastic
will void warranty.
W A R N I N G
> ALWAYS test color changer for conductivity
after assembly or repair. Proper conductivity is
required to assure entire color changer can be
properly grounded when installed.

8. Acquire a container of water and fill it with
about 4-inches (10.6cm) of WATER. Position the
hose in the container filled with water.
9. There should be no more than 6 bubbles per
minute coming from the outlet of the hose that is
submerged.
10. If there are more than 6 bubbles per minute,
remove the color valve assembly, replace the
valve seat (77367-00) and reinstall color valve
assembly. If the new seat does not correct the
problem, either the manifold block or color valve
assembly is defective.
11. Proceed to the next color valve and repeat
Steps 2 thru 11.
12. When all the color valves are checked out,
then check the purge valve assembly repeating
Steps 2 thru 11.
13. Once all valves are operational, deactivate
the 3-way valve, and then disconnect the air
lines used for testing from the color changer.
14. With an ohmmeter, check for conductivity
between the output plate on the color changer
and earth ground. There should be 10 ohms or less
between the two points (see Figure 14).
