3. ఆపరేటింగ్ సూచనలు
The FUZHUI G3/4 Thermostatic Mixing Valve is designed for precise temperature control, ensuring a consistent water temperature output between 35°C and 60°C.
3.1 ఉష్ణోగ్రత సర్దుబాటు
- The valve features a rotary knob on top for temperature adjustment.
- Rotate the knob to select the desired mixed water temperature within the operational range of 35°C to 60°C.
- The valve will automatically mix hot and cold water to maintain the set temperature, even with fluctuations in incoming water pressure or temperature.
3.2 Anti-Scalding Safety Feature
This valve includes a built-in safety device. In the event of a cold water supply failure, the valve will automatically shut off the hot water supply to prevent scalding, enhancing user safety.

5. ట్రబుల్షూటింగ్
If you encounter issues with your thermostatic mixing valve, refer to the following troubleshooting guide:
| సమస్య | సాధ్యమైన కారణం | పరిష్కారం |
|---|---|---|
| నీటి ఉష్ణోగ్రత అస్థిరంగా ఉంది | Fluctuating water pressure; debris in valve; incorrect calibration. | Check water pressure regulators; clean any inline filters; consult a plumber for recalibration. |
| No hot water / Only cold water | Hot water supply failure; valve stuck. | Check hot water heater and supply; if cold water supply failed, the anti-scalding feature may have activated. |
| No cold water / Only hot water | Cold water supply failure; valve stuck. | Check cold water supply; if cold water supply failed, the anti-scalding feature should have activated to shut off hot water. If hot water is still flowing, the valve may be faulty. |
| తగ్గిన నీటి ప్రవాహం | Debris in valve or pipes; partially closed shut-off valves. | Check and clean inline filters; ensure all shut-off valves are fully open. |
| కనెక్షన్ల చుట్టూ లీక్లు | వదులైన కనెక్షన్లు; దెబ్బతిన్న సీల్స్. | Tighten connections; replace seals or O-rings if damaged. |
