1. Heat dissipation efficiency drops by more than 50%
2. Water flow noise affects life
3. May cause system corrosion
4. Increase energy consumption by 20%-30%
3. Detailed exhaust steps
| steps | Operating Instructions | Things to note |
|---|---|---|
| 1. Preparation | Prepare a flat-blade screwdriver, a water container, and a dry towel | Turn off the heating valves in other rooms |
