3. Using a medium sized pipe wrench, loosen the union pipe fitting that attaches
the control unit to the bottom of the pressure vessel.
4. With your free hand placed under the control unit (so as to not let it drop),
completely unscrew the union, allowing the control unit to separate from the
pressure vessel (place a small container under the pressure vessel to catch
any remaining soda).
5. Tip the control unit upside down, to empty any soda that may still be in the
inlet fitting. With a pair of needle nose pliers, remove the factory installed
1/8” restrictor and place it in a safe place.
