When to replace the lower hood fixing screws
Even though screws are not typical wear parts, they can be damaged or lost during servicing or by corrosion in a damp technical room. Missing or worn screws may leave the hood loose, which can cause vibration, noise or stress on the plastic housing.
- Replace screws that are corroded, stripped or bent and no longer tighten correctly.
- Use this pack when reassembling the hood after replacing electronics, covers or brackets.
- Restore all four fixing points if one or more original screws have been lost.
Installation guidelines
Fitting the Zodiac lower hood fixing screw M4 x 6 mm pack of 4 R0741400 is simple and can be carried out during routine maintenance, always with the unit powered off.
- Disconnect the chlorinator from the mains before opening or adjusting the control box.
- Position the lower plastic hood correctly on the control unit, aligning all fixing holes.
- Insert each new M4 x 6 mm screw by hand first to avoid cross threading in the plastic.
- Tighten the screws evenly until the hood is firmly seated, without over tightening or deforming the cover.
- Check that the hood is stable and that no gaps remain where dust or splashes could enter.
Using the original R0741400 screw set ensures that the lower hood remains securely fixed, protecting the internal electronics and maintaining a clean, professional finish on the control unit.
