SHOWER MIXING VALVE CARTRIDGE REMOVAL

: Reinsert cartridge by pushing it all the way into the body and until
the front of the ears on the cartridge shell are flush and aligned with the body.
Replace the retainer clip so that the legs straddle the cartridge ears and slide
down into the bottom slot in the body. This prevents the cartridge from rotating
and locks it in the body. Reinstall stop tube and handle. Tighten handle screw
securely, and replace the handle cover. The red flat on the stem must point UP

when mounting the knob handle (down for lever handle).
