How to Drain the Heating Manifold
1. First find the installation position of the manifold. Generally, it is above the inlet pipe and below the outlet pipe.
2. In addition, the water in each manifold should be drained, so the general valve should be turned off first, and the water distribution pipe should remember to start releasing water from the left to the right. The small water valve above the first water distribution pipe does not move, and the second and fourth small water valves are twisted 90 degrees to the right respectively, and only the water in the first small water distribution pipe is released.
3. Next, connect the prepared plastic tube to the air outlet, and turn the small screw on the air outlet to the right to start the water release. The water just released is very turbid, and the temperature of the water is low. After placing a few basins, the water gradually becomes clear and the temperature gradually rises, which can be clearly felt by hand.
4. When the first water distribution pipe ends, the small water valve is closed, and the second water pipe is started to be put in, and the small water valve of the second water distribution pipe is twisted open, and the water is discharged in sequence until all.
5. After all is over, touch the water inlet pipe with your hand, the water temperature has risen significantly. At this time, open the main valve and all small water valves, and continue to discharge water until the temperature of the water outlet pipe is satisfactory.
