Tool Preparation and Safety Confirmation
Before disassembly, prepare a flathead screwdriver, insulating tape, and a test pen. First, turn off the main power switch. After checking the switch panel for no current with the test pen, temporarily secure nearby wiring with tape to prevent accidental contact. Carefully check the surrounding tiles or waterproof layer for integrity to avoid secondary damage during disassembly.
Step-by-Step Disassembly Procedure
- Panel Removal: Gently pry the decorative cover clips with a screwdriver. If it is screw-fixed, remove the surface screws first.
- Internal Structure Separation: Record the wiring connection sequence, then loosen the terminal screws.
- Main Body Removal: For slot-type installations, press the retaining clips first, then slide it horizontally to remove it.
- Waterproofing Inspection: Check the aging of the sealing rings; mark and replace them if necessary.
Operational Prohibitions and Emergency Handling
Live operation may cause a short circuit risk. If you accidentally touch a wire, immediately disconnect the power. For stubborn screws, apply a small amount of lubricant; do not pry forcefully, as this may strip the threads. When reassembling, it is recommended to take a picture of the original wiring diagram with your mobile phone to ensure zero error during restoration.
