4. Installation Instructions
This wallplate is designed for easy installation over a pre-existing telephone or cable device. Follow these steps carefully:
- Prepare the Area: Ensure the power to the circuit is turned off at the main electrical panel before beginning. If replacing an existing wallplate, carefully remove the old plate and its mounting screws.
- Position the Device: Ensure the telephone or cable device is properly installed and secured within the electrical box. The device's connector should protrude through the .406 inch hole of the new wallplate.
- Align the Wallplate: Place the Leviton 78013 wallplate over the device and align the screw holes on the wallplate with the mounting holes on the electrical box or device bracket.
- Secure the Wallplate: Insert the provided mounting screws into the top and bottom holes of the wallplate. Gently tighten the screws until the wallplate is flush with the wall surface. Do not overtighten, as this can crack the wallplate or strip the screw threads.
- Restore Power: Once the wallplate is securely installed, restore power to the circuit at the main electrical panel.
5. Operation
The Leviton 78013 wallplate serves as a protective and aesthetic cover for your telephone or cable device. Once installed, it requires no further operation. Ensure any cables or telephone lines are properly connected to the device behind the wallplate.
6. Maintenance
To maintain the appearance and integrity of your wallplate:
- Clean with a soft, damp cloth.
- Avoid abrasive cleaners, harsh chemicals, or solvents, as these can damage the finish.
- Periodically check that the mounting screws are snug. Do not overtighten.
7. Troubleshooting
- Wallplate does not fit flush: Ensure the device behind the wallplate is properly seated and not protruding excessively. Check for any obstructions within the electrical box.
- Screws do not align: Verify that the electrical box or device bracket is correctly installed and aligned. If replacing an older plate, ensure the new plate's screw spacing matches the existing setup.
- Wallplate appears damaged after installation: This may be due to overtightening the mounting screws. Loosen the screws slightly. If the damage is significant, the wallplate may need replacement.
