Type TM Parallel 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 (ot-left, old-right). Exercise caution when soldering. 4. Flush pipes thoroughly after system has been connected. 5. Assemblies installed on a recirculated hot water system MUST be piped according to S REQUIRED PIPING METOD #5 (see page 4). 6. Refer to page 3 of this bulletin for correct Setup Instructions. Maximum Operating Pressure 125PSI (8 KPA) for ot 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 12.

2 ASSE 117 TM-22B-2P ADJUSTMENT AND SERVIE ONLY 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: Parallel 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 ), 5 ) the valves when turned to full OT will deliver water in excess of 12 F (49 ) and the limit stop MUST BE RESET BY TE INSTALLER!
