Installation Instructions
This GE Spring Wound Timer is easy to install and will fit in any standard 2-1/2 inch deep wall box. The timer fits both toggle and rocker/decorator wall plates in a single or multi-gang
vertically installed wire box. If you are unsure about the installation of this timer please contact a licensed electrician.
1. Turn power off at circuit breaker or fuse box before installation.
2. Remove current wall plate and switch from vertically installed wall box.
3. Wires should be stripped 1/2 inch long.
4. Remove timer from package, carefully remove the knob center nut and remove either faceplate or stainless
steel wallplate (depends on model purchased). Look at the back of the timer and you will see TOP, LINE1, and
LOAD1, See figure 1.
5. Loosen the LINE1 and LOAD1 screws with either a Flat Head or Phillips screwdriver and insert the wire into
the holes on back of the timer.
6. Insert the Line Side wire from the wire box into hole marked LINE1 under the wire plate, and tighten
the LINE1 screw.
7. Insert the Load Side wire from the wire box into hole marked LOAD1 under the wire plate, and tighten
the LOAD1 screw.
8. Attach ground wire from box to the ground lug on the top of the timer.
9. Tug each wire to verify connection, re-tighten if needed.
10. Insert timer into the 2-1/2” wall box being careful not to pinch any wires. Be sure the TOP (indicated on back
of timer) is facing up. Fasten the timer to the wall box using the screws provided.
11. Place standard toggle or rocker/decorator wall plate on timer referring to the appropriate diagram below. Be
careful to not over tighten wall plate screws.
NOTE: When using a toggle wall plate, the two wall plate screws are not required in order to secure the wall plate.
The nut will hold the wall plate in position once assembled. If using the rocker/decorator style wall plate screw the
wall plate into the top and bottom tabs of the timer using the screws supplied with your current wall plate. BE SURE
TO NOT OVER TIGHTEN!
12. Slide the timer dial plate over the knob extension of the timer. It should fit snugly onto the wall
plate. Be sure the “OFF” is oriented with the TOP of the timer as marked on the timer. Carefully
screw on the provided nut.
13. Push timer knob onto knob extension. Be sure the pointer is lined up with “OFF” on dial plate.
14. Turn power on at the circuit breaker or fuse box.
