Delta AE Bellows Plunger Kit Installation Instructions

Warning - Turn Off The Unit & Unplug it From The Wall Before Starting This Procedure

  3. Remove The Clip From The Top Of The Solenoid.
  4. Remove The Solenoid By pulling it up and away from the shaft and set it aside
  5. Slide The Spanner Nut Tool Over the shaft, aligning the two dowel pins in the tool with the holes of the flute (looks like a cap at the base of the shaft).
  6. Using a 3/4 inch wrench (or an adjustable wrench) turn the Spanner Nut In a counter-clockwise direction (Once started, you can unscrew it by hand)

    Warning: Do Not Use pliers or vice grips in trying to remove the shaft - the shaft is easily distorted (The Solenoid coil will no longer slide over the shaft - and a replacement is not available (unless you buy the whole assembly for approximately $300).
