  1. Start by turning the steam module to stand-by mode and allowing unit cool down before trying to perform the CPC valve replacement.  To speed up the cool down, you can manually fill the boiler with via the manual fill function with module in stand-by mode.  Be sure to exhaust all steam from the boiler via the steam tap before moving on to next step!

    • Be sure to turn off the power to the module and unplug module while performing service!

    • To gain access to the back of the module it is recommended to remove the steam tap(s) line(s), drain line, and water in on the manifold.

    • Using a 19mm open end wrench, start removing the top CPC valve by turning the fitting counter clockwise to loosen.

  2. Remove the fitting from the back of the manifold. Repeat this process for the second CPC fitting. Apply a small amount of Permabond food safe thread sealant to the threads of the new CPC valve.

    • Smooth the thread sealant around evenly on the threads of the fitting.

  3. Carefully thread the new valve into the manifold starting with the bottom CPC first, and then the top fitting.   The threads of the CPC fitting are a tapered fit and will get harder to tighten, this is normal, make sure fittings are tightened down with good force.
