4. Usage of TMVs
For wash hand basins, bidets, baths and showers in hospitals, schools, sport and leisure facilities, prisons and other public buildings.
DN15-DN25 thermostatic valve with built-in check valve;
Normal water pressure can be used normally;
We recommend that thermostatic valves be installed indoors;
Make height difference between thermostatic valve and solar energy;
It is best to have a drop of 3 floors. If there is no drop of 3 floors, we recommend that customers install pumps.
Remark: It can be used normally without a booster pump, and the use effect may be reduced.
DN32-DN100 thermostatic valve has no built-in check valve;
Inconsistent hot and cold water pressures, check valves should be installed on the side with low pressure;
If you can't judge which side the pressure is low, install a check valve on both sides;
If the cold water is not pressured tap water, a booster pump is also required at the cold water end.

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