Installation Tips:
1. All installations should be carried out by a Licensed Professional
2. Install in accordance with markings on valve body, hot water inlet-marked H, cold water inlet-marked C
3. After temperature setting, if inlets temperature or pressure fluctuates, outlet temperature variation is within +/-2 ℃
4. The external check valves at inlets prevent cross-flow of hot&cold water when inlets pressure is not the same
5. If the ratio between two inlets is too large, one flow-limiting valve should be fixed at the side of higher pressure
6. Prior to installation, provisions should be made to flush the piping of any debris or other foreign materials to ensure proper system operation
