Systems with Color Change and without
Dump Valves
NOTE: This procedure relieves pressure through the
sampling valve.
1. Complete all steps under Single Color Systems,
page 51.
2. Close the A side shutoff valve (SVA), F
the A side sampling valve (RVA).
3. Direct the A side sampling tube into a waste con-
tainer.
4. See F . 66. Open the color change module. Using
IG
the solenoid identification labels as a guide, press
and hold the override button on each color solenoid
until flow from the sampling valve stops.
5. Press and hold the solvent solenoid override until
clean solvent comes from the sampling valve, then
release.
6. Shutoff the solvent supply to the color change stack
solvent valve.
7. Press and hold the solvent solenoid override until
solvent flow from the sampling valve stops.
8. Open the A side shutoff valve (SVA), F
the A side sampling valve (RVA).
