About This CMP Troubleshooter

This interactive tool is built from CMP manual-backed equipment data and the related PoolDial troubleshooting guide. It is designed to separate safe owner checks from technician checks and to keep unsupported assumptions out of the diagnostic flow.

Manual-backed scope

This tool intentionally stays inside the CMP manual-backed symptom set. It does not guess at hidden board faults or unsupported alarm meanings. The paths here come from DEL UV-C, DEL AOP, DEL AOP-S, and DEL Ozone manual data already represented in the CMP spec pages and troubleshooting guide.

When to use the article instead

Use the full CMP DEL sanitizer troubleshooting guide when you need part numbers, flow values by model, or a broader comparison across UV-C, ozone, and AOP systems.

Frequently Asked Questions

Does a CMP DEL sanitizer replace chlorine?

No. The manual-backed CMP DEL material treats UV, ozone, and AOP products as supplemental sanitation, so the pool still needs a normal residual sanitizer.

What flow should I verify on DEL AOP-S?

The manual-backed AOP-S data lists a 5 to 20 GPM water flow range and references minimum 5 GPM injector flow for active operation.

What should I check before replacing a DEL UV lamp?

Confirm source power, breaker status, wiring condition, connector seating, and water fouling near lamp connections before replacing lamp parts.
