?? Critical Safety & Installation Warnings

DANGER - HIGH VOLTAGE: High voltage is present inside timer boxes. Always turn off the main circuit breaker before opening the cover or touching the timer dial. Failure to do so can result in fatal electric shock.

COMPATIBILITY LIMIT: Not compatible with digital timers or "T100R" series plastic dials that require "snap-on" style plastic trippers. Forcing these onto plastic dials will damage the timer face.

TRANSACTION DETAIL: Package contains one (1) ON tripper, one (1) OFF tripper, and two (2) screws ONLY. It does not include the timer motor, enclosure, or dial.

?? Professional Tips for Success

Set the Clock First: Ensure the timer dial is rotated to the current time before installing your trippers to ensure the cycle starts correctly.
The "Click" Test: After tightening, manually rotate the dial one full turn (power OFF) to ensure the trippers engage the internal silver trip lever.
Firm Seating: Ensure the "v-shape" of the tripper is flush against the edge of the dial before tightening to prevent vibrating loose.
Visual Check: The silver tripper is "ON" and the gold tripper is "OFF" for quick schedule verification at a glance.
