Air valves must be installed vertically, i. e. the buoy inside them must be kept in a vertical state to avoid affecting the exhaust. 2. When installing, it is better to install with the partition valve, so that when it needs to be removed for repair, the system can be sealed and the water will not flow out. 3. It is generally installed at the highest point of the system, which is conducive to improving the exhaust efficiency. 4. Low system pressure is not only harmful to exhaust, but also increases the possibility of leakage. Note: 1. The installation position of the exhaust valve must be the highest point of the pipeline. In order to reduce the internal pressure of the system, it can reduce the pressure and prevent negative pressure. 2. Please allow 0- 1 inch error due to manual measurement. 3. Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard.
