ADJUSTMENT AND SEVICE NOTE: Thermostatic Water Mixing Valves are EGULATING mechanisms, which must be regularly maintained to provide best performance. Frequency of cleaning depends on quality of local water conditions and usage. (See Maintenance Guide and ecord MG-1). TO ESET ADJUSTABLE HIGH TEMPEATUE LIMIT STOP: Leonard Model TA Thermostatic Water Mixing Valves are simple in design and may be easily cleaned, adjusted and repaired. If the installation is accessible, servicing may be completed without disconnecting the valve. STOP TAP-29 LT SET SCEW WEB ETAINING ING MU-13D 1. Loosen LT set screw. 2. While valve is running,, turn stem to maximum HOT setting of 11 (3) or lower. 3. Loosen pointer screw and remove TAP- handle, retaining ring (MU-13D). (See Page ). Loosen LT set screw and remove stop (TAP-29). eplace stop so it rests against the web on the LEFT side of the valve cover. 6. eplace, retaining ring and tighten LT lock screw and replace handle. WANING WANING! This Thermostatic Mixing Valve has an adjustable high temperature limit stop, which must be checked. If temperature is too high, the installer MUST ESET this stop immediately. Always check the temperature of the mixed water when the handle is turned to full HOT. Hot water in excess of 11 is DANGEOUS AND MAY CAUSE SCALDING! The high temperature limit stop is factory set at approximately 11 (3) with an incoming hot water supply temperature of 13 (7). If the incoming hot water on the job is higher than 13, the valve when turned to full hot will deliver water in excess of 11 and the high temperature limit stop MUST BE ESET BY THE INSTALLE.

INSTUCTIONS FO DISMANTLING VALVE 1. Turn off hot and cold supplies to this valve. 2. Loosen LT set screw 3. emove four cover screws MU-2C, lift off cover and thermostat group 681 (DWG 1). After installing new parts, it will be necessary to reset the limit stop to obtain correct temperature range from Cold to Hot. See page 2 instructions "TO ESET ADJUSTABLE HIGH TEMPEATUE LIMIT STOP." TO CLEAN POT SLEEVE ASSEMBLY To clean port sleeve assembly TAG-1 (DWG 2.): emove base stud TA-. Back off jam nut 3 as far as it will go into base. Slide port sleeve assembly toward port sleeve nut and lift out of valve base. Clean port sleeve assembly with a soft cloth; DO NOT use abrasives such as emery cloth or sandpaper. After cleaning, wash parts in clean water and reassemble in valve base. When reassembling port sleeve assembly BE SUE TO INSTALL WITH LONG END IN BASE AND SHOT END AT POT SLEEVE NUT. Locate one set of port slots facing directly toward front of the valve. Tighten jam nut 3 just enough to hold port sleeve in place, (do not cramp or distort port sleeve by exerting excessive pressure when tightening port sleeve nut). TO CLEAN THEMOSTAT GOUP To clean thermostat group 681 (DWG 1.), remove handle by loosening lock screw and pull off. emove thermostat group by pushing rod through cover. BE CAEFUL NOT TO PULL COILS OUT OF SHAPE. If deposit has collected on thermostat coil, clean it off with a brush in cleaning solution and rinse before re-assembly. Cleaning solution should be noncorrosive and grit free. COVE SCEW 1.

See instructions "To eset High Temperature Limit Stop" to properly reset limit stop. After installation, adjustment, cleaning, always check the temperature of the valve when turned to full HOT per the warning on the front page, using a thermometer. Also check and if necessary adjust the temperature of the hot water source. EXCESSIVELY HOT WATE (OVE 11 o F) IS DANGEOUS AND MAY CAUSE SCALDING!! EMEMBE!
