4. Remove the tank light from the mounting hole in
the rim (See Fig. 3).
5. Unplug the wiring connections from the electronic
board (See Fig. 2).
6. Unsnap the board from the clips holding it on the
back of the faceplate.
B. INSTALL NEW ELECTRONIC BOARD
1. Carefully snap the new electronic board into the
holding clips on the back of the faceplate.
2. Reconnect the wiring to the new board (See Fig.
2), including the power supply, valve motor connec-
tor, and turbine/position switch connector.
3. Slide the new board’s tank light into the mounting
hole in the rim (See Fig. 3), with the bulb angled
toward the front.
4. Slide the new board’s salt lid sensor into the
mounting clip on the rim (See Fig. 3), with the
wires leading toward the inside.
5. Snap the top cover / lid assembly back into place
on the rim, taking care not to pinch any wires.
C. PROGRAM THE NEW BOARD
1. Plug the power supply into the electrical outlet. A
model code (620) and version are briefly shown in
the display. Then the words “PRESENT TIME”
appear and “12:00 PM” begins to flash.
2. Press the
r UP or s DOWN buttons to set the
present time. Up moves the display ahead; down
sets the time back. Be sure AM or PM is correct.
NOTE: Once the unit has been connected to the
Kenmore
®
cloud, as detailed on Page 2, the
present time will be up dated and maintained
automatically via Wi-Fi.
