These thermostatic water mixing valves can be adjusted to deliver water at temperatures exceeding 110°F (43°C). After installation, the installer must check the outlet water temperature and adjust the temperature setting to ensure delivery of a safe water temperature not exceeding 110°F (43°C). See “Temperature Adjustment” next page. 1. Valve should be installed where it can be easily cleaned, adjusted or repaired. 2. Inlets are furnished with NPT connections. When soldering close to this unit, DO NOT OVERHEAT, internal components may become damaged. 3. Leonard recommends that unions and shutoffs are installed on the inlets and outlet. 4. Use solder or pipe cement sparingly. Supply pipes should be flushed before the valve is connected. Flush outlet pipe and valve as soon as it is connected. 269-LF & 369-LF WARNING: When using flex hoses be careful, swivel connectors may damage inlet checks and / or element on outlet on 269-LF and 369-LF models.

Open mixed water outlet. 3. With the fixture in the full open position, calibrate the mixed water outlet temperature by placing a thermometer in the mixed water stream. Loosen knob set screw with 5/64” allen wrench. Adjust the setting of the valve to obtain the desired temperature (counterclockwise, to increase temperature-clockwise to decrease temperature.) 4. Tighten knob set screw to lock temperature setting. WARNING WARNING! This thermostatic mixing valve’s temperature setting MUST be checked. If the temperature is too high (above 110ºF, 43ºC), the temperature knob must be adjusted immediately. Excessively hot water is DANGEROUS AND MAY CAUSE SCALDING!!
