When to replace electronic board fixing screws
Although screws are not typical wear parts, they can become damaged or lost during maintenance or as a result of corrosion in humid technical rooms. Missing or damaged screws may allow the board to move, creating stress on solder joints and connectors.
- Replace screws that are rusted, stripped or bent and no longer tighten properly.
- Use original screws when reassembling a control box after replacing a board or support.
- Restore any missing screws to ensure all fixing points are used and the board lies flat on its support.
Installation guidelines
Installing the Zodiac electronic board fixing screw set R0743400 is straightforward but should always be done with the control unit powered off. Correct tightening avoids damage to the board while keeping it stable.
- Disconnect the control unit from the mains and confirm that no voltage is present before opening the housing.
- Position the electronic board correctly on its support, aligning all mounting holes.
- Insert each R0743400 screw by hand to engage the thread without cross threading.
- Tighten the screws evenly until the board is secure, without over tightening or bending the PCB.
- Check that the board cannot move and that no components touch the housing or other metallic parts unintentionally.
Using the original Zodiac screws with the correct size and thread ensures a neat, reliable assembly that protects the electronics from vibration and mechanical stress.
