Step 1: Mark the Fixing Positions of the Old Glass Tube
Use a marker to accurately mark the fitting positions between the old glass tube and the fixing clips on the transparent acrylic backboard. This ensures the new tube can be perfectly aligned with the original installation points to avoid position deviation.
Step 2: Remove the Silicone Waterproof Electrode Sleeve
Grasp the white silicone waterproof electrode sleeve at the end of the tube. If the sleeve is stuck to the electrode, gently twist it back and forth to gradually pull it off the electrode, then set the sleeve aside for later use.
Step 3: Disconnect the Electrode from the Power Cord
After fully removing the electrode sleeve, separate the power cord from the tube's electrode wiring by unwinding the twisted connection, completely detaching the old tube from the power circuit.
Step 4: Install and Secure the New Glass Tube
Take out the new glass tube. Align your thumb with the original position marked in Step 1, and press the tube smoothly into the slots of the fixing clips. Ensure your finger applies force in the same direction as the clip slots to avoid uneven pressure that could crack the tube, and secure all clip points one by one.
Step 5: Reconnect the Electrode Wiring
Once all tube fixing points are securely installed, tightly twist the power cord and the tube's electrode wiring together in a "braided" (twist-like) manner. This ensures a stable, secure connection and reliable circuit conduction.
Step 6: Replace the Silicone Sleeve to Complete the Replacement
Put the silicone waterproof electrode sleeve removed in Step 2 back over the electrode wiring, fully enclosing the connection to restore the waterproof seal. The glass tube replacement is now complete.
Important Safety Notes
- Always disconnect the power supply before starting any operation to avoid electric shock hazards.
- Handle glass tubes with extreme care, as they are fragile. Avoid heavy impacts or excessive force during installation.
- Ensure the wiring is tightly twisted and the silicone sleeve fully covers the connection to prevent moisture ingress and short circuits.
