10. Rotate the mixer by hand until the set screw is visible, remove the screw with a 3/32” Allen
wrench.
11. Pull out the mixer. If it’s not damaged keep it for a spare.
12. Clean the upper block of any deposits. Do not use chlorinated cleansers.
13. From the lower block remove the flushing plug and flow nozzle. Clean if necessary.
14. Remove the copper negative cell and discard.
15. Inspect and clean the lower block if necessary, including the internal ports. Do not use
chlorinated cleansers.
16. Check the positive electrode (gold) and clean with a soft cloth (not an abrasive cleaning pad
or sandpaper) if needed. Do not loosen or remove the electrode. If the O-ring seal is broken
water can seep in between the gold tube and copper stud and prevent electrode operation. The
electrode is made of pure gold tubing pressed onto a copper stud and is very easily damaged,
especially by over tightening the nut that secures the electrode to the block.
17. Remove all O-ring seals: (2) for the negative cell, (4) on the flow nozzle, and (2) on the flushing
plug as shown below.
