The Outdoor Plus DT041723 is a mechanical dial timer designed to replace standard wall switches for controlling outdoor devices like lighting, irrigation, and pool pumps. It is energy-efficient and does not require electricity to function. Warning: Installation and service must be performed by qualified personnel only due to electric shock hazards.

Installation









- Turn off power at the circuit breaker.
- Remove the existing switch cover plate.
- Strip wires approximately 0.5 inches according to the gauge on the back of the timer.
- Insert wires under the terminal screw pressure plates and tighten securely using copper wire only.
- Install the timer into a 2.5-inch deep junction box, ensuring the 'TOP' mark is correctly oriented. Secure with provided screws.
- Attach the time dial plate over the threaded extension, ensuring the 'OFF' mark is at the top.
- Secure the dial plate with the provided nut (do not overtighten).
- Attach the knob to the 'D' shaped shaft, aligning the pointer with the 'OFF' mark.
- Restore power at the circuit breaker.
Operation
To set the timer, turn the knob clockwise to the desired time. The device will automatically turn off once the time elapses. If the timer is wired for reverse action, it will turn the device on at the end of the preset time.
Safety
- Do not use for precision timing applications (e.g., sun lamps, saunas).
- Do not touch with wet hands.
- Do not disassemble; there are no user-serviceable parts inside.
- Ensure power is off before maintenance.
- Do not use in areas with flammable gases or liquids.
Troubleshooting
