Operation

The HG135 Thermostatic Mixing Valve automatically mixes hot and cold water to deliver a consistent, tempered water temperature at the faucet. The factory preset temperature is 120°F, which is a common safe temperature for household use.

Temperature Adjustment:

The outlet temperature can be adjusted anywhere from 85°F to 130°F. To adjust the temperature, locate the adjustment knob on the valve. Refer to the product diagram for its exact location. Use a suitable tool (if required) to turn the knob to increase or decrease the mixed water temperature. Always test the water temperature with a thermometer after adjustment to ensure it is within a safe and desired range.
