1. Close the valves on the branch pipes of each loop of the water separator and water collector first, and then open the valve of the "gas gathering" pipeline to discharge gas from the outlet needle of the water separator. There is a manual exhaust valve on each radiator. The user can gently twist the manual exhaust valve and stop twisting the exhaust valve immediately after hearing the exhaust sound. After exhausting, if the radiator is still not hot, please ask professional maintenance personnel to check and find out the reason before solving it. Users must not blindly drain water.
2. When deflating, in order to avoid water spraying on the wall, you can cover it with a towel. The deflation needle should be unscrewed gently, not pulled out, and then screwed on when there is water flowing out.
3. If the radiator is hot on the top and cold on the bottom, it may be blocked by foreign bodies, so you should contact professional maintenance personnel for flushing.
It is illegal to drain the heating water without authorization, which will not increase the heating temperature, but will affect the whole heating cycle system.
