Find the water mixing valve for your touchless faucet. You can identify the mixer by its three pipe connections.
Loosen the temperature adjustment lever retaining screw using a Phillips screwdriver. The screw is secured within the slotted section of the lever.
Turn the adjuster lever to the full "Hot" position. Have a helper activate the faucet by placing his hand between the sensor near the base of the faucet and the flow of water from the spout. Allow the hot water to run for approximately 30 seconds to ensure it reaches its peak temperature.
Check the temperature of the water by placing a cooking thermometer in a drinking glass and filling it with hot water. A temperature range of approximately 120 to 130 degrees is common; however, your own setting at the tap can be adjusted to suit your needs.
Turn the lever on the mixer valve slowly and in small increments toward "Cold" as the water continues to flow, until the desired temperature is reached.
Tighten the lever retaining screw clockwise with the screwdriver.
