Dometic CCC2 filter icon clean and reset
Dometic CCC2 operating instructions say the filter icon appears after 1000 fan hours, the air conditioner or heat-pump filters should be cleaned or replaced, and the selected zone runtime is cleared by holding INSIDE TEMP and F/C for 3 seconds.
Owner-safe checklist
- Turn the affected zone off from normal thermostat controls before handling owner-accessible filters.
- Clean or replace only owner-accessible air conditioner or heat-pump filters as the RV installation allows.
- Wash reusable filters with soap and warm water, let them dry, and reinstall them before operating the system.
- For the selected zone, hold INSIDE TEMP and F/C for 3 seconds to clear the filter icon after filter service.
