Compatibility and Buyer Check
Before ordering, confirm that your system is part of the Zodiac AquaPure Ei Series and that your manual calls for part number R0512900. This screw set is listed for select AquaPure Ei electronic salt water chlorine generator models, including APURE35 and APURE35PLG.
Do not order by image alone. Small hardware can look similar, but screw length, thread size, and fitment may vary by model.
If the plug is cracked, missing, or not sealing correctly, review the Zodiac R0511800 plug replacement before replacing only the screws. If the locking ring is damaged or difficult to secure, check the Zodiac R0511300 locking ring replacement as well.
What This Screw Set Does
These screws help secure parts of the compatible AquaPure Ei salt chlorine generator assembly. Replacing damaged or missing screws can help restore proper fitment during maintenance or repair.
This screw set will not fix low chlorine output, electrical faults, a failed electrode, leaks from cracked housings, or control board issues. If the electrode assembly is worn or failing, compare this part with the Zodiac R0511400 35 electrode replacement.
Before You Order
Check these details before purchasing:
- Confirm the part number R0512900.
- Verify your system model is APURE35, APURE35PLG, or another compatible AquaPure Ei model.
- Confirm your repair requires M3 x 12 mm screws.
- Compare the screw size and head style with your original hardware.
- Inspect the plug, locking ring, housing, and electrode area for additional damage.
- If the housing is cracked or worn, review the Zodiac R0512000 pod housing replacement.
- If your system has display, power, or control issues, check the Zodiac R0512300 TS control PCB assembly instead.
Installation Notes
Turn off power to the salt water chlorine generator and pool equipment before servicing the unit. Keep the original screws or damaged hardware nearby for comparison before installing the replacement set.
Install each screw carefully and tighten evenly. Do not overtighten, cross-thread, or force the screws, because this can damage plastic housing parts or make future service harder. After installation, check that the serviced area is secure before restarting the system.
Maintenance Tips
To help prevent future screw and hardware issues:
- Inspect screws during routine salt cell or generator maintenance.
- Replace stripped, rusted, or damaged screws promptly.
- Keep the screw holes clean and free from debris.
- Avoid using the wrong screwdriver size.
- Do not force screws into misaligned parts.
- Check nearby seals and housings before assuming the screws are the only problem.
