Hydro Master 1/2" Brass Feed Water Pressure Regulators With Union 0571300

Description: This 1/2 inch feed water pressure regulator is for use in commercial and residential hydronic heating systems to fill the boiler and piping system with water, and to maintain water pressure in the system at all times. It also provides make-up water to the system in the event of system leaks. Note: This is for boiler only. Operation Instructions Other1. To fill the system, open the shutoff valve upstream of the regulator. This Valve must always be kept open when the system is in operation. Water will flow into the system until it is full and under pressure.NoticeSeries with Fast Fill and Purge Lever 1/2" valves are equipped with a unique and simple "fast fill and purge lever" which permits rapid filling of the system and sustained flow for air purging. When the lever is raised to the vertical position it pushes a removable "Push Rod" down. This manually forces the valve to a wide open position for maximum flow. Returning the lever to its normal position releases the tension on the rod permitting the valve to maintain normal system pressure.CautionAlways observe the Boiler Pressure Gauge when using this feature. Using this feature with the purge valve closed can result in over pressurizing the system or exceeding the pressure safety Relief Valve setting. Over pressurization can result in water discharge from the Relief Valve. This feature can be disabled to prevent tampering or accidental misuse of the fast fill feature by simply unscrewing the fast fill lever cap and removing the push rod.2. The regulator is set to deliver water to the boiler at approximately 15lbs. pressure. This pressure is sufficient for a 3 story building. To reset the reducing valve for higher pressure (when the pressure is not sufficient to lift the water to highest radiation):A. Calculate the number of feet from the regular to the top of highest radiation.B. Multiply this number by 0.43 and add 3 lbs. This will give the pressured required to raise the water to the highest radiator and keep the system under pressure.3. To reset the regulator valve:remover the fast fill lever cap, and loosen the lock nut. To raise the reduced pressure - slowly turn the adjusting screw clockwise until the system gauge indicates the pressure required. To lower the reduced pressure - turn the adjusting screw counterclockwise. After completing adjustments, tighten the lock nut and replace the fast fill lever cap.NoticeHydro Master not responsible for boiler failure on boilers without low water cutoffs.WarningAnnual inspection of all water system safety and control valves is required and necessary. Regulator inspection, testing and cleaning assures maximum life and proper product function.
