| steps | Operation content |
|---|---|
| 1 | Check whether the power supply of the wall-hung boiler is turned off to ensure safety |
| 2 | Confirm the value displayed by the water pressure gauge of the wall-hung boiler (normal range is 1-1.5bar) |
| 3 | Prepare the appropriate tools, such as a refill key or screwdriver |
| 4 | Make sure there is no debris blocking the water supply valve |
2. Specific steps for adding water to the floor heating wall-mounted boiler
The following is the detailed process of adding water:
