LV-101 August, 2018 1360 Elmwood Avenue, Cranston, RI 02910 USA Phone: 401.461.1200 Fax: 401.941.5310 Email: info@leonardvalve.com Web Site: http://www.leonardvalve.com INSTALLATION ADJUSTMENT SERVICE THERMOSTATIC WATER MIXING VALVE SERIES LV-983, LV-983-LF & LV-984, LV-984-LF IMPORTANT! Provide valve serial number, (located on valve cover) when ordering parts!! INSTALLATION 1. Valve should be installed at a location where it can easily be cleaned, adjusted or repaired. 2. The inlets are clearly marked on the valve body. Union angle strainer checkstops furnished must be installed on both supply lines as shown above. 3. A shutoff valve must be installed on the outlet pipe. Type LV valves do not have a built-in shutoff. 4. Use solder, or thread sealant sparingly. Supply pipes should be flushed before the valve is connected. Flush outlet pipe and valve as soon as it is connected. CAUTION All thermostatic water-mixing valves have limitations. They will not provide the desired accuracy outside of their flow capacity range. Consult the flow capacity chart on page 5. Minimum flow must be no less than as shown. REMEMBER! THIS IS A CONTROL SYSTEM WHICH MUST BE CLEANED AND MAINTAINED ON AREGULAR BASIS (SEE MAINTENANCE GUIDE AND RECORD MGR-1000). 125 PSI (8.6 BAR) MAXIMUM OPERATING PRESSURE ! WARNING:This product can expose you to chemicals including lead, which is known to the State of California to cause cancer. For more information, go to www.P65Warnings.Ca.gov 2 INSTALLATION REQUIRED METHODS OF PIPING LV SERIES OPERATION 1. Verify that the temperature of the hot water source is properly set and maintained. Shutoff and isolate the circulator pump. 2. Loosen LTR set screw located on temperature adjustment knob with allen wrench. 3. Turn on enough fixtures to flow approximately 10 GPM, turn knob clockwise until it stops (full cold) then counterclockwise until it stops (full hot), three times to exercise the thermostatic element. 4. Set mixing valve to the desired temperature, (See warning tag for temperature set point). Tighten LTR set screw. 5. Shut off all fixtures. Setup is complete. 6. Turn on circulator. With all fixtures still off, (no water flowing) observe the circulation temperature until it stabilizes. 7. If temperature rises, close balance valve until desired temperature is reached METHOD W Required when TEMPERED WATER IS CIRCULATED. METHOD #1 Required when TEMPERED WATER is NOT CIRCULATED. Only the hot water supply to the mixing valve can be circulated with this piping arrangement. 3 REMEMBER! THIS IS A CONTROL DEVICE WHICH MUST BE CLEANED AND MAINTAINED ON A REGULAR BASIS. (SEE MAINTENANCE GUIDE AND RECORD, MGR-1000). INSTALLATION CONTINUED Leonard Type LV 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. NOTE:Thermostatic Water Mixing Valves are REGULATING 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 Record MGR-1000). TROUBLESHOOTING INSTRUCTIONS SERVICE WARNING WARNING!This Thermostatic Mixing Valve has an Locking Temperature Regulator (LTR) which must be checked. If the temperature is too high, the installer MUST RESET this adjustment immediately. Always check the temperature of the mixed water after installation. Excessively hot water is DANGEROUS AND MAY CAUSE SCALDING! The LTR is factory set at approximately 120°F (49°C) with an incoming hot water supply temperature of 150°F (65°C) If the incoming hot water supply for your installation is higher than 150°F (65°C), the valve may deliver water in excess of 120°F (49)° and the LTR MUST BE RESET BY THE INSALLER.

MGR-1000 12/91 1360 Elmwood Avenue, Cranston, R. I. 02910 USA Phone: 401-461-1200 Fax: 401-941-5310 IMPORTANT!! MAINTENANCE GUIDE & RECORD AFTER INSTALLATION, DELIVER TO THE OWNER’S MAINTENANCE PERSONNEL All water temperature control valves require regular maintenance, depending upon usage and local water conditions. The steps below provide a guide to the proper care of all thermostatic and pressure actuated mixing valves manufactured by Leonard Valve Company. 1. After 30 to 60 days of normal operation, check the performance of the valve, disassemble the valve (per the instructions) and inspect the internal parts. Make certain the moving parts operate freely and that no foreign deposit has collected on any of the internal parts of the valve. 2. If the valve operates properly and there is no evidence of any deposit, reassemble the valve, recheck and if necessary reset the high temperature limit (per Warning Tag). ESTABLISH A PERIODIC MAINTENANCE SCHEDULE TO REINSPECT THIS VALVE AT INTERVALS NO GREATER THAN EVERY SIX TO TWELVE MONTHS! SEE THE MAINTENANCE FORM ON THE REVERSE SIDE OF THIS CARD. 3. If there is evidence of inconsistent performance or of any deposit on the internal parts, clean the valve thoroughly (per the instructions), replace parts if necessary, reassemble the valve and make certain it is functioning properly. Recheck and if necessary reset the high temperature limit stop (per Warning Tag). ESTABLISH A REGULAR MAINTENANCE SCHEDULE TO REINSPECT THIS VALVE WITHIN 60 DAYS (PER STEP 1 ABOVE). THE FREQUENCY OF REINSPECTION SHOULD THEN BE BASED UPON THE CONDITION OF THE INTERNAL PARTS AT THE MOST RECENT REINSPECTION. IN NO CASE SHOULD REINSPECTION INTERVALS EXCEED EVERY SIX TO TWELVE MONTHS. SEE THE MAINTENANCE RECORD FORM ON THE REVERSE SIDE OF THIS CARD. These recommendations provide a guide for scheduling timely maintenance of water temperature control devices. DO NOT DISCARD!!
