How to Replace the Cap and Gel on an Edge 200 PPM Probe
This covers replacing the cap and gel on an edge 200 PPM probe in detail
Gel needs to be replaced when:
1) The manual reading is not matching the controller after multiple calibrations
2) After calibration of the probe, the reading automatically drops away from calibration.
Gel goes bad when:
1) When the chlorine in the body of water goes above 10ppm
2) When there is too much water flow going through the controller
3) Gel is old (Typically 12 months)
When replacing gel does not always mean you need to replace the cap. As long as the cap is not leaking or the tip of the cap is intact and not discolored you can reuse the cap.
Items needs:
1) PPM probe
2) Electrolyte gel that is not expired
3) New cap if needed
Steps:
- Isolate controller from flow
- Remove PPM from probe housing
- Remove cap from PPM probe
- Clean out all old gel from probe tip and cap
- Loosen transparent ring around cap to uncover the overflow hole
- Prepare electrolyte gel by screwing on funnel cap
- Turn electrolyte gel upside down to force gel into funnel cap
- Insert funnel of electrolyte gel into cap and squeeze with constant pressure making sure no air bubbles get into gel.
- Fill to inner step
- Remove electrolyte gel and inspect to make sure no air is in cap
- Insert probe into cap and screw all the way in. Gel will come out overflow hole
- Replace transparent ring around cap to cover overflow hole
- Wipe excess gel from cap
- Install PPM probe back in probe housing
- Turn flow back on to controller
- Wait a few hours for probe to reacclimate to pool water
Troubleshooting: Probe acclamation could take up to 24 hours. If still not tracking after 24 verify that no air bubbles are in the cap and ensure that the cap is fully screwed on.
