Dear bono'an wall mounted furnace users
The heating season has already started. According to our return visit to some users, we found that many users did not move in or temporarily did not operate after installing bonoan series wall hanging, and many users had no one at home for a long time. In winter, the temperature is low, so the antifreeze protection function of the wall mounted furnace can only work under the condition of complete water, electricity and gas supply. If the power is cut off, water or gas supply is cut off, there will be hidden danger that the internal parts of the wall mounted furnace will be damaged by freezing, causing economic losses and inconvenience to you.
Therefore, we solemnly inform:
In the case of not using the wall mounted boiler, it is necessary to drain the water in the boiler. Please operate according to the following methods:
1. Drain the water from the heating system, drain the water at the radiator end of the heating system or the ground heating connection, and use the air pump to blow out the water in the heating system. Observe that the water pressure pointer of the operation panel of the wall mounted boiler is "0", indicating that there is no water pressure in the heating system.
2. Drainage of domestic hot water system: close the valve of tap water inlet pipe under the wall leaning furnace, open the domestic hot water faucet and put it on the ground for drainage until no water flows out, and then use the air pump to blow out the water stored in the equipment hot water system, indicating that there is no water in the domestic hot water system.
