VMS-35 (UB1213) BATTERY REPLACEMENT
PROCEDURE:
NOTE Normal valve operation under 24 VAC power need not be interrupted
during battery replacement; however, the fail-safe function will not be avail-
able until the new battery is in place, connected and sufficiently charged (typi-
cally 2-4 hours).
1. Refer to the picture (left) to locate and disconnect the Red and
Black wires from the battery.
2. Remove the two battery mounting bracket screws and remove
the battery and bracket.
3. Place the bracket over the new battery and install the
assembly as shown, using the two screws removed in step 2
(above).
4. Connect the Black wire to the black (unmarked) terminal.
5. With 24 VAC power present, connect the Red wire to the
red terminal. VMS-35 circuitry will automatically charge the
battery. (If 24 VAC is not present, the valve may move to its
fail-safe position, depending upon residual charge in the new
battery.)
6. Recycle or dispose of the old battery properly. Do not
incinerate!
