7. Solder the other lead from the new cartridge to the terminal with the BLUE lead on the switch.
8. Using long­nose pliers, carefully replace the switch in the case with the blank terminal on the switch facing to­
wards the cartridge (to ensure the UP position is ON), being careful not to pinch the leads.
9. Placing your finger inside the case to support the switch, secure the switch in place by screwing the non­lock­
plate screw on the side of the switch closest to the grille.
10. Gently insert the new cartridge into the case, being careful not to pinch the leads, and making sure the foam
gasket on the cartridge is above the aluminum ring.

Models 515BSLX, 515SBGX, 515SBG-18X, and 515SBG-18XF
It is recommended that the following procedure be performed on a table or other flat surface to support the car­
tridge and case in order to avoid the possibility of breaking the cartridge leads.
To replace the R180 cartridge in the 515X Series (except the 515SDX), proceed as follows:
1. Slide the supplied shrink-wrap tubing over both leads on the R180 replacement cartridge.
2. Using a #4 (.050 in., 1.3 mm) hex wrench, loosen the setscrew on the base of the grille.
3. Unscrew and remove the grille (turning counterclockwise).
4. Gently pull out the old cartridge, being careful not to break the leads.
5. Using wire cutters, cut the lead from the old cartridge marked by the dot as close to the cartridge as possible,
so the lead sticks out from the handle. Mark the cut lead with a small piece of tape.
