3. Operating Instructions
Follow these instructions for effective treatment of condensate pans and humidifiers.
3.1. Condensate Pans
- For noticeably fouled pans: Use two or more Pan-Treat tablets per ton of system capacity. Repeat this treatment until the system is clean.
- For subsequent treatment or clean condensate pans: Use one Pan-Treat tablet per ton each month.
- Placement: Position the tablets away from the drain and in an area where they will achieve maximum contact with dripping condensate. This ensures more complete cleaning action and treatment.
- For larger systems: If using many tablets is impractical, consider using Nu-Calgon's PanPads condensate pan products.
3.2. Humidifiers
- Pan-Treat tablets can be used to condition humidifier water to prevent odors and deposit build-up.
- Use 2-4 tablets every four to six weeks as needed.
- Clean and rinse out the humidifier reservoir on a regular basis.

4. Maintenance
Regular application of Pan-Treat tablets is key to maintaining clean condensate pans and humidifiers. For condensate pans, apply one tablet per ton of system capacity monthly. For humidifiers, apply 2-4 tablets every four to six weeks. Consistent use prevents the accumulation of sludge and scum, ensuring optimal performance and preventing costly issues.
5. Troubleshooting
Nu-Calgon Pan-Treat tablets are designed to prevent common issues. If you experience any of the following problems despite regular use, consider these points:
- Persistent Odors: Ensure tablets are placed where they have maximum contact with condensate. Increase dosage if the pan is heavily fouled, following initial cleaning instructions.
- Plugged Drains/Overflows: Verify that the correct number of tablets is being used for your system's capacity. If the pan was severely fouled initially, repeat the higher dosage treatment until clean. Check for any physical obstructions in the drain line that tablets cannot resolve.
- Ineffective Treatment: Confirm the product is not expired. Ensure tablets are fully dissolving and reaching all areas of the pan.
For issues beyond these basic checks, consult an HVAC professional.
