Inspect and Replace the CPS valves
To inspect and replace the CPS valves, see Figure 53:
1. Separate the lower and upper housing from the chassis as described
previously.
2. Vent the controller to remove all pressure to the CPS.
3. Use a 9/16 inch socket or wrench to remove the retaining nut
for the valve
coil
.
4. Remove the coil from the valve base
.
5. Use a flat-head screwdriver to remove the valve stem
from the valve base
.
6. Ensure the O-ring
remains in the valve base and do not lose the valve
body
.
Note that the vent valve has a spacer that goes above the valve
body and must be in the vent valve assembly for proper operation.
7. Remove the valve body from the valve stem and inspect the sealing surface
for any contamination or damage.
