When the floor heating switch is turned on, drainage work is required, otherwise the floor heating water will be blocked and will not flow when turned on. The floor heating switch is off when it is sideways and on in the same direction as the pipe, the specific steps to turn on the floor heating switch correctly are as follows:
< p>1. the floor heating valve group, including main valve, bypass valve and air discharge valve.2. Open the main water inlet valve and the water inlet bypass valve.
3. Connect the hose to the return water discharge valve and open it.
4. Open the first return water diversion valve.
5. Open the second bypass valve when clean, bubble-free water flows from the return water purge valve.
6. Use the same method to open the varemaining branch lines.
7. Finally, when opening the main water return valve, close the return water drain valve to complete the operation.
How to drain water from underfloor heating
Step 1: Close the main water return valve (pull it in the direction perpendicular to the pipe) To prevent water from entering the return pipe is not drained as well.
Step 2: Leave only one side of your home's water dispenser open and the others closed.
Step 3: Connect a water pipe to the return water exhaust valve, unscrew the exhaust valve, and use a small basin to catch the water flowing out of the water pipe.
Step 3: When finished, repeat the second step, close one pipe that released water, open the other pipe, and so on, until the hot water enters the floor heating pipe.
Ventilation stagesu underfloor heating
1. Prepare the water hose and clamps. First find the water drain position, then find the ventilation hole of the water inlet pipe on the water dispenser. Touch it with your hands. The hot one is the water inlet pipe and the cold one is the return pipe.
2. Connect the water pipe to the air release valve of the water inlet pipe of the water dispenser. At this time you must pay attention. There should be someone next to you when the air is released. . Because the deflation hose may burst. Prepare a towel and wrap it around the valve, then use pliers to open the valve. Make sure to do this gently so the water doesn't leak everywhere.
3. Then put the air back into the water line. First, close the main valve of the main water return pipe. The main valve is a long green or red handle. It will close automatically when it isrotated 90 degrees. The method is the same as the water supply above, just connect the hose to the air release valve of the water dispenser.
4. Next, install a single water pipe. Operation method: First close the main water return valve. Then close the small valves of the water inlet and return of the geothermal pipes one by one, and then deflate the air relief valve of the return pipe of the water dispenser until hot water sort. Start by closing the small water inlet and return valves of the first pipe, then open the small water inlet and return valves of the second geothermal pipe. Simply deflate the geothermal tubes one by one.
5. Check if deflation is successful. Mainly observe whether there is sewage and gas bursting inside. If so, it will basically reach a stable state.
6. Finally, open the water tap, includings the main return pipe and each pipe. Finally close the purge valve tightly. Underfloor heating and ventilation are completed.
