For more information, go to www.p65warnings.a.gov DOMESTI OUTLET INLET OLD INLET INSTALLATION 1. Type TM manifold systems are factory pre-assembled and tested and include large and small thermostatic water mixing valves which function as a system to meet both high and low demand for tempered water. 2. System should be installed at a location where it can easily be cleaned, adjusted or repaired. 3. System supplies must be connected as shown (Hot-left, old-right). Exercise caution when soldering. 4. Flush pipes thoroughly after system has been connected. 5. If this assembly is installed on a recirculated hot water system it MUST be piped according to correct piping method see pages (4 & 5). 6. Refer to page 3 of this bulletin for correct Setup instructions. Maximum Operating Pressure 125 PSI (86 KPA) for Hot and old Water. AUTION All thermostatic water mixing valves have limitations. They will not provide the desired accuracy outside of their flow capacity range. onsult the capacity chart on page 9. Minimum flow must be no less than as shown. REMEMBER! THIS IS A ONTROL SYSTEM WHIH MUST BE LEANED AND MAINTAINED ON A REGULAR BASIS (SEE MAINTENANE GUIDE AND REORD MGR-1). 136 Elmwood Avenue, ranston, RI 291 USA Phone: 41.461.12 Fax: 41.941.531 Email: info@leonardvalve.com Web Site: http://www.leonardvalve.com
117 ASSE ADJUSTMENT AND SERVIE Leonard Type TM 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 valves. NOTE: High Low Manifold Systems include Thermostatic Water Mixing Valves, 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 Record MGR-1. WARNING These mixing valves are equipped with an adjustable high temperature limit stop factory set at approximately 12 F (49 ) with an incoming hot water supply temperature of 15 F (65.5 ). If the hot water supply temperature of the job is greater than 15 F (65.5 ), the valves when turned to full will deliver water in excess of 12 F (49 ) and the limit stops MUST BE RESET BY THE INSTALLER! TO RESET ADJUSTABLE HIGH TEMPERATURE LIMIT STOP: Serial# s starting with 52, 82, 92, 152 THERMOSTATI SREW TM-26 OLD FINE ADJUSTMENT SREW H SNAP AP STOP SREW LTR SET SREW 1. Loosen LTR set screw. 2. Remove SNAP AP, SREW & WASHER. Remove. 3. Temporarily place on the spline rod, turn RIGHT for warmer temperature, turn LEFT for cooler temperature. When valve is delivering warmest temperature desired, remove the pointer. 4. Replace on the spline rod so that its RIGHT edge is resting against the STOP SREW located on the RIGHT SIDE OF THE. 5. The new maximum temperature has now been set. Test this temperature by holding a thermometer under the flow of water to be certain it is as desired. * LIMIT STOP MUST BE RESET AND REHEKED EAH TIME HANDLE IS REMOVED. STOP LTR WEB (REST STOP AGAINST SREW) SET SREW 1. Loosen LTR SET SREW, remove SREW. 2. Adjust to maximum desired temperature. 3. Remove, replace on spline rod with STOP (which is cast into the underside on the pointer), resting against the BOTTOM side of the WEB on the FINE ADJUSTMENT SREW. 4. If fine adjustment is needed, adjust FINE ADJUSTMENT SREW on the cover, loosen for hotter or tighten for cooler temperature. 5. Replace and check temperature, if set to desired temperature replace SREW, and tighten LTR SET SREW. 6. The new maximum temperature has now been set. Test this temperature by holding a thermometer under the flow of water to be certain it is as desired. * LIMIT STOP MUST BE RESET AND REHEKED EAH TIME HANDLE IS REMOVED. IMPORTANT! BOTH MIXING S MUST BE SET AT THE SAME OPERATING TEMPERATURE. SEE PAGES: 7 & 8 FOR OMPLETE PARTS BREAKDOWN heck for significant variations in outlet flow. Thermostatic valves will NOT provide the desired accuracy outside of their flow capacity range. Minimum flows must be no less than shown (see Flow apacities, page 9). If installed on a recirculated hot water system, make certain the valve is piped according to Leonard Required Piping Method (see page 4 & 5). REMEMBER! THIS IS A ONTROL DEVIE WHIH MUST BE LEANED AND MAINTAINED ON A REGULAR BASIS. (SEE MAINTENANE GUIDE AND REORD, MGR-1). 2
