Before manually adding water to the wall-hung boiler, open the exhaust valve inside the wall-hung boiler and radiator, and open the water replenishing valve to replenish water. Pay attention to the exhaust holes on the radiator when replenishing water, and close the exhaust valve when water flows out.
It would be much more convenient if it was an automatic exhaust valve. When adding water, note that the water pressure gauge value is about 1.0 ~ 1.5 kg. Excessive water supply will cause pressure relief and water leakage. Close the water supply valve after water supply.
Extended data:
1, three grounded power supplies must be used, otherwise the wall-hung boiler will not start normally, and there will be great security risks.
2, the wire must pay attention to waterproof, power socket should not be installed in waterways or water sources, nor can it be hung under the furnace wall.
3. The power supply voltage must meet the voltage range required by the wall-hung boiler (generally stated on the nameplate and manual of the fuselage), otherwise the wall-hung boiler will not start normally and the main board of the wall-hung boiler will be damaged. If the power supply voltage can't meet the needs of the wall-hung boiler, it is necessary to install a voltage regulator.
4. When the water temperature rises to 60 degrees, the noise increases, and the primary and secondary heat exchangers scale and need to be cleaned in time.
