Inquire with governing authoritiesfor additional local requirements.WARNING!FAILURE TO COMPLY WITH PROPER INSTALLATION ANDMAINTENANCE INSTRUCTIONS COULD CONTRIBUTE TOTHE VALVE FAILURE, RESULTING IN INJURY AND/ORDEATH.TO ENSURE THE ACCURATE AND RELIABLE OPERATION OFTHIS PRODUCT, IT IS ESSENTIAL TO:• Properly design the system to minimize pressure andtemperature variations.• This valve is factory preset. However, it can be adjustedto deliver scalding temperatures. Check outlet tem-perature to ensure it does not exceed 105°F (41°C).Make sure temperature limit stop is properly re-set tomaximum 105°F (41°C) following valve maintenance orrepair. Tampering with limit stop in any way may resultin scalding temperature causing serious bodily harm and/or death.WARNING!WARNING!Need for Periodic Inspection and Yearly Maintenance:Periodic inspection and yearly maintenance by a licensed con-tractor is required. Corrosive water conditions, inlet temperaturesover 200°F (93°C), and/or unauthorized adjustments or repaircould render the valve ineffective for service intended. Regularchecking and cleaning of the valve’s internal components andcheck stops helps assure maximum life and proper productfunction. Frequency of cleaning and inspection depends uponlocal water conditions.PSIGPM0 10 20 30 40 50 60 70 80 90 10076543210E480G480Certified toNSF/ANSI/CAN 61-9 & 372ASSE 1070This product meets the reduced Q test statistic criteria of0.5 ppb for lead per Section 9.5.1.1 of NSF/ANSI/CAN 61.
