Wall hung furnace commissioning method is suitable for initial use or because of power failure (stop gas), long time no need to recharge after discharge.

步骤如下：

The following steps are as follows:

1打开壁挂炉下边的自来水阀门，然后逆时针旋转补水阀，让自来水进入供暖系统。观察壁挂炉上压力表（部分型号机器无压力表，请查看显示屏上显示的压力数值），当压力达到1.5bar（1.5公斤）时，顺时针关闭补水阀。

1 open the tap water valve under the wall hanging furnace, then rotate the replenishment valve counterclockwise to let the tap water enter the heating system. Watch the pressure gauge on the wall (part of the machine no pressure meter, check the pressure value on the display screen). When the pressure reaches 1.5bar (1.5 kg), the water supply valve is closed clockwise.

2请依次旋开各组散热器片上面的手动排气阀，将气体排出。当气体排尽水出来时，关闭手动补水阀。如果是地暖，就通过分水器上面手动排气阀排气。

2 please turn off the manual exhaust valve above each radiator piece in turn and discharge the gas. When the gas drained out, turn off the manual replenishment valve. If the floor is warm, the exhaust valve is exhausted through the manual exhaust valve on the distributor.

3再次查看压力表，确保系统水压在1.0-1.5bar（1.0-1.5公斤之间）即可。如果压力不足1.0bar，请通过第一个步骤补水至规定值。

3 check the pressure gauge again to ensure that the system pressure is between 1.0-1.5bar (1.0-1.5 kg). If the pressure is less than 1.0bar, please fill up the water to the specified value through the first step.

补水压力达到1.0—1.5bar后，请一定要关闭补水阀，否则，系统超压泄压阀会一直漏水，可能浸湿室内物品；另一方面，如果自来水停水，壁挂炉会因失水而停止工作。

After the water pressure of 1 - 1.5bar, please be sure to close the water supply valve, otherwise, the system overpressure relief valve will be leaking water, may soak indoor items; on the other hand, if water is stopped, the wall will stop working because of water loss.

4打开燃气阀门→开机→然后调节冬夏模式，按上下键调节供暖或洗浴水温即可。如果不点火，一般是水泵卡死，用平口螺丝刀拨动水泵叶轮旋转几圈即可。

4 turn on the gas valve, turn on the machine, adjust the winter and summer mode, adjust the heating or bath temperature according to the up and down keys. If it does not ignite, usually the pump dies, then use the flat mouth screwdriver to pump the impeller of the pump for several revolves.

5如果不小心补水时超压过多，可以通过排水阀或者散热器上排气阀排水。对于没有安装排水阀的地暖管道（或散热器），可以采用下述方式排水泄压：关闭自来水阀门→逆时针打开补水阀→然后打开热水阀门（或淋浴喷头）泄压，当压力达到1.0-1.5bar（最佳压力范围）时→关闭热水阀门（或淋浴喷头）→然后顺时针关闭补水阀→最后开启自来水阀门即可（如果不开启就无生活热水）。

5 if overpressure is overdue, it can be drained by drain valve or radiator exhaust valve. For a warm pipe (or radiator) that does not install a drain valve, it can be drained by the following way: turn off the tap water valve, reverse clockwise open water supply valve and then open the hot water valve (or shower nozzle) to release pressure, when the pressure reaches 1.0-1.5bar (the optimum pressure range) - close the hot water valve (or shower nozzle). Then turn off the replenishment valve clockwise and finally open the tap water valve.

壁挂炉工作时，压力会有所上升，这是正常的，是加热时水受热热胀所致。大部分壁挂炉都具有超压保护泄压装置，当系统压力超过3.0bar（3.0公斤）就会泄压。

When the wall hanging furnace is working, the pressure will increase. This is normal, it is caused by the water heating and thermal expansion. Most of the wall mounted furnaces have overpressure relief pressure relief devices. When the system pressure exceeds 3.0bar (3 kg), the pressure will be released.
