5. Using the 9/16-inch wrench and the 5/8-inch wrench, loosen the brass
nut that attaches the copper tubing to the inlet of the check valve and
disconnect that tubing
6. Using the 9/16-inch wrench and the 1/2-inch wrench, loosen the brass

9. Using the 9/64-inch hex wrench, remove the 6 mounting screws and
remove the bottom valve clamp block
10. Lift the sample solenoid valve and plumbing assembly out of the heated
