- Connect hoses and drain system
- Circulate descaling solution
- Flush with fresh water
- Clean filters and condensate components
- Reassemble and restore power
- Test operation and combustion

Routine descaling helps maintain efficiency, protect internal components, and keep the system operating reliably.
