3 Balanced Pressure Proportioners FOREWORD 2017-JAN-11 REV. 0 This manual is intended as a guide for ANSUL proportioners. They will be used as a component in a bladder tank proportioning system or in an in-line balanced pressure proportioning system. These systems must be designed by competent, experienced engineers to ensure compatibility, proper functioning of the system, and compliance with the NFPA codes, as well as local and end-user requirements. If there are any questions, or further information is required, contact Tyco Fire Protection Products Technical Services, Marinette, WI Those who design, install, operate, refill, inspect, or maintain these systems should read this entire manual. This equipment is designed for use on only Class A and Class B Hydrocarbon fires. Only ANSULITE Alcohol-Resistant Aqueous Film- Forming Foam (AR-AFFF) Concentrates, at the percentage recommended for the product, can be used on Class B Hydrocarbon and Polar Solvent fires. Proportioners are mechanical devices that need periodic care and inspections to provide reasonable assurance that they are operable. Inspection should take into consideration the environment, system use, and user inspection policy; but as a minimum should be conducted annually or after discharge. Maintenance, which provides maximum assurance that the ANSUL foam concentrate is effective and the system is operable, should be conducted at annual intervals, or earlier when indicated by an inspection. ANSUL Foam Concentrates must be stored within the temperature range listed on the container and/or the technical data sheet. If the concentrates require storage outside of these temperature ranges, consult Tyco Fire Protection Products, Technical Services, Marinette, WI Also, particular attention should be given to the ANSUL Field Inspection Manual (Part No ) which deals with the testing procedures for ANSULITE AFFF Concentrates. The testing procedures for non-afff foams are covered in the National Fire Protection Association (NFPA) Standard 11 (2016 Edition), Chapter 6.! WARNING Foam is a conductor of electricity and should not be used on Class C electrical fires.! CAUTION Before installing any style foam proportioner(s), ensure the piping, both above-ground and under-ground, supplying fire water to the proportioner(s) has been properly flushed of any debris which could potentially cause damage to, or prevent, the proper operation of the proportioner.

7 Balanced Pressure Proportioners SECTION 1 SYSTEM DESCRIPTION 2017-JAN-11 REV. 0 PAGE 1-1 SYSTEM DESCRIPTION A Balanced Pressure Proportioner functions by maintaining equal pressures in the foam concentrate and water inlets to the proportioner. This balancing ability allows the proportioner to be used over a wide range of flows and pressures. The proportioning device will also respond quickly to changes in the water inlet conditions. This manual consists of the following types of Balanced Pressure Proportioners: 1. Bladder tank Proportioners, often referred to as Ratio Flow Controllers, allow a portion of the incoming water pressure to be diverted into a pressure vessel containing a bladder filled with foam concentrate. The foam concentrate is pushed from the bladder into the foam concentrate piping to the proportioner. 2. FLOWMAX CL Proportioners, or bladder tank variable range proportioners, are similar to bladder tank proportioners but have a variable orifice opening for the foam concentrate responding to water flow rate. 3. In-Line Balanced Pressure Proportioners operate by passing the foam concentrate from a positive displacement pump through a pressure balancing spool valve. The spool valve senses the pressures in the foam concentrate and water lines and balances these pressures. The pressures can also be balanced manually on In-Line Balanced Pressure Proportioners equipped with optional foam balancing valves by manually regulating the flow of foam through the valve while watching the duplex gauge. The foam concentrate then enters the proportioner. An orifice in the proportioner, sized for the foam concentrate type, regulates the flow of pressurized foam concentrate entering the water stream. 4. FLOWMAX PPW Proportioners are similar to In-Line Balanced Pressure Proportioners with a variable orifice opening for the foam concentrate responding to water flow rate and a diaphragm valve for balancing inlet foam concentrate pressure. This is not offered with a manual override. Notes 1. The standard Between Flange Proportioners have the cone portion downstream in addition to a flow direction arrow. A removable section of pipe must be added downstream to allow for the servicing of the between flange proportioner. 2. Standard Flanged Proportioners can be bolted directly to pipe flanges and do not require a removable section of pipe for servicing. 3. FLOWMAX CL Proportioners can be installed between two 150 lb. ANSI pipe flanges and do not require a removable section of pipe for servicing. 4. FLOWMAX PPW Proportioners can be installed between two 150 lb. ANSI pipe flanges and do not require a removable section of pipe for servicing.

8 SECTION 2 DETECTION AND ACTUATION PAGE 2-1 REV JAN-11 Balanced Pressure Proportioners DETECTION AND ACTUATION Foam fire suppression systems may require listed or approved automatic detection devices capable of sensing and indicating heat, smoke, and/or flames as required by local code and installed to the NFPA 72 standards. Automatic detection devices must use a reliable source of power that meets the NFPA 72 standards. All automatic devices for fire suppression systems must include a means of immediately signaling an alert in the event of a detection device failure. Alarms and Signaling Requirements Foam fire suppression systems may need to include audible alarms that will alert personnel when the system is operating, as well as when any supervised component of a system has failed. The appropriate type and number of alarms must be installed and must be located where they will be effective. Alarms must be sounded both before and after discharge of the system. Alarms that indicate system failure must be immediate, as well as distinctive form hazard and operation alarms. Refer to the detection sections of NFPA 11, 2016 Edition, and NFPA 72 for detection systems and actuation devices. Follow the regulations of the Authority Having Jurisdiction (AHJ) and relevant insurance underwriters. FM Global requires the submission of the alarm detection system for review and approval prior to installations for FM Global insured locations. Interconnection Considerations Interconnections can be made through the alarm detection system. Considerations should be given to the requirements of the NFPA 72 - National Fire Alarm and Signaling Code, NFPA 4, and insurance underwriters based on specific job requirements and the Authority Having Jurisdiction (AHJ).

Between Flange Proportioners and Flanged Proportioners are available in 3 in., 4 in., 6 in., and 8 in. sizes. Up and Downstream Piping Requirements! CAUTION For proper mixing of the concentrate into the water supply, install the proportioner with the required minimum straight pipe lengths of the same nominal diameter before and after the proportioner. Before the proportioner (upstream), there must be straight pipe that is 5 times the proportioner nominal diameter. After the proportioner (downstream), there must be straight pipe that is 2.5 times the proportioner nominal diameter. Maximum Equivalent Length of Concentrate Piping Water inlet and foam concentrate piping combined must be designed for a maximum differential pressure loss of 2 psi (0.14 bar) based on median flow to the proportioner selected. Concentrate Type The foam concentrate inlet of each proportioner includes an orifice held in place with a retaining ring. The orifice is sized for specific ANSUL foam concentrates. Each proportioner has a nameplate factory stamped with concentrate type, percentage, and orifice size. Flow Range Nominal flow ranges for proportioners are noted in the latest revisions of the following ANSUL data sheets: Threaded Proportioners (2 in. and 2 1/2 in.) (Form No. F-85144). Between Flange Proportioners (3, 4, 6, and 8 in.) (Form No. F-8542) Flanged Proportioners (3, 4, 6, and 8 in.) (Form No. F-85143) Nominal flow ranges are for Newtonian type Aqueous Film- Forming Foams (AFFFs). Flow ranges for non-newtonian Alcohol Resistant Concentrates have higher low end flow rates. Always refer to the UL Certification Directory and FM Approval Guide for Listed flow ranges. Flow range is based on the total water flow through the proportioner. Operating Pressure The operating pressure for all proportioners is a maximum water pressure of 250 psi (17.2 bar) and a minimum water pressure of 30 psi (2.07 bar), except the 8 in. Flanged Proportioners are rated at 225 psi (15.5 bar). However, standard bladder tanks are rated for a maximum water pressure of 175 psi (12 bar). Specially designed bladder tanks for higher pressure are available. Refer to the ASME nameplate on the tank for maximum design pressure.

10 SECTION 3 RATIO FLOW CONTROLLERS PAGE 3-2 REV JAN-11 Balanced Pressure Proportioners INSTALLATION! CAUTION Before installing the proportioner(s), ensure the piping (both above-ground and under-ground) supplying fire water to the proportioner(s) has been properly flushed of any debris which could potentially cause damage to or prevent the proper operation of the proportioner.

11 Balanced Pressure Proportioners SECTION 3 RATIO FLOW CONTROLLERS 2017-JAN-11 REV. 0 PAGE 3-3 OPERATION All balanced pressure systems use a modified venturi device called a proportioner or ratio controller (see Figure 3-1). Proportioners are available in a variety of sizes and styles to match the required flow ranges and pipe sizes. CONCENTRATE INLET WATER INLET FOAM SOLUTION DISCHARGE FIGURE As water flows through the proportioner nozzle, a low pressure area is created (see Figure 3-2). It is in this low pressure area that the pressurized concentrate mixes with the water stream. A metering orifice at the concentrate inlet regulates the rate of concentrate flow and thus determines the percentage of concentrate in the foam solution. Balanced pressure proportioning systems require the foam concentrate pressure to be balanced with the water pressure at the proportioner inlets. This balance meters the proper amount of foam concentrate into the water stream. LOW PRESSURE AREA PRESSURE RECOVERY AREA FIGURE Ratio Flow Controllers require use of a bladder tank to supply foam concentrate. Reference the Vertical and Horizontal Bladder Tanks Installation, Filling, and Maintenance Manual (Part No ) for piping to the Ratio Flow Controller and bladder tank.

12 SECTION 3 RATIO FLOW CONTROLLERS PAGE 3-4 REV JAN-11 Balanced Pressure Proportioners MAINTENANCE A Ratio Flow Controller has no moving parts. In the event of clogging with foreign materials, the proportioner can be removed from the piping and cleaned. The foam concentrate orifice is removable with a snap ring pliers and can be cleaned and reinstalled. As the Ratio Flow Controller is a part of a bladder tank installation, reference the Vertical and Horizontal Bladder Tanks Installation, Filling, and Maintenance Manual (Part No ) for system inspection and maintenance requirements

21 Balanced Pressure Proportioners SECTION 5 IN LINE BALANCED PRESSURE PROPORTIONERS 2017-JAN-11 REV. 0 PAGE 5-5 INSTALLATION (Continued) To prepare the In-Line Balanced Pressure Proportioner for placement in service, complete the following steps: 1. Remove all cord, wrapping, and banding ties. Examine the entire assembly and component parts for concealed shipping damage. 2. Install the atmospheric foam concentrate storage tank, foam concentrate pump, pump starter/controller and appropriate piping, valves, strainers, check valves, unions, etc., as determined by the system design engineer. 3. Install the In-Line Balanced Pressure Proportioner(s) in the water supply line(s) running to the foam discharge device(s) as determined by the system design engineer. Proportioners may be installed in either the horizontal or vertical position but make certain the proportioner check valve is installed with upward flow or horizontal flow with top of check valve up (see Figure 5-5). The spool valve must be installed with the longitudinal axis in the horizontal (level) position (see Figure 5-5). For system dimensions, refer to the in-line balanced pressure proportioner dimensional tables on page Install an automatic concentrate control valve (hydraulic or electric actuated type) at the inlet to each in-line balanced pressure proportioner. Spool Valve Position Examples (Side View) On any automated fire protection system (deluge, pre-action, dry pipe, or wet pipe) an automatic concentrate control valve is required. On manual fire protection systems, the Concentrate Valve on the in-line balanced pressure proportioner would be normally closed and opened manually by the system operator. 5. Install the piping from the pressurized foam concentrate supply to the foam concentrate inlet on the proportioner assembly or automatic foam concentrate valve if required by the design. 6. Install the pressure control valve in the foam return line to the foam concentrate storage tank. For proper operation, the foam concentrate pressure must be adjusted by the pressure control valve to be greater at the foam concentrate inlet of the In-Line Balanced Pressure Proportioner assembly than the highest available flowing water pressure at the proportioner inlet. Foam concentrate pressure should be 15 psi to 25 psi (1.03 bar to 1.72 bar) more than the highest flowing water pressure of the system. 7. Install any auxiliary equipment referring to the manufacturer s instructions. 8.

22 SECTION 5 IN LINE BALANCED PRESSURE PROPORTIONERS PAGE 5-6 REV JAN-11 Balanced Pressure Proportioners OPERATION To operate the In-Line Balanced Pressure Proportioner, complete the following steps: 2. Observe the duplex gauge on the in-line proportioner assembly to assure the foam concentrate and water pressures are balancing. The red needle is water pressure and the black needle is foam concentrate pressure. The duplex gauge needles should read within ± 4 psi (0.28 bar) of each other. Valves must always be maintained in the NORMAL positions when the system is in a stand-by condition to assure proper system operation. Proper valve positioning MUST BE checked prior to proceeding with operating instructions. Normal Valve Positions: Concentrate Valve...OPEN Drain Cock Valves...CLOSED Manual Foam Balancing Valve (if equipped)...closed The In-Line Balanced Pressure Proportioner is designed to function automatically when the valves are in the NORMAL position. 1. With the foam concentrate pump supplying pressurized foam concentrate to the in-line proportioner assembly, observe the pressure gauge to ensure the foam concentrate is a minimum of 15 psi (1.03 bar) higher than the flowing water pressure, as read on the red needle of the duplex pressure gauge. If the concentrate pressure is lower, the pressure control valve should be adjusted to provide a higher pressure. If the pressures are not balancing and normal valve positions are verified during the acceptance testing, proceed to the troubleshooting section of this manual or contact the system design engineer for technical assistance. In emergency situations, with ANSUL In-Line Balanced Pressure Proportioners equipped with the optional manual foam balancing valve, proceed to the Manual Override section below. Manual Override For manual regulation of the in-line balanced pressure proportioners, complete the following steps: 1. Close the foam concentrate valve. 2. Open the manual foam balancing valve slowly and adjust to balance the water and foam concentrate pressures on the duplex gauge. The foam concentrate pressure may be slightly higher than the water pressure, but must not be lower than the water pressure. The duplex pressure gauge must be continually observed to assure that the foam concentrate and water pressures are balanced.

26 SECTION 5 IN LINE BALANCED PRESSURE PROPORTIONERS PAGE 5-10 REV JAN-11 Balanced Pressure Proportioners TROUBLESHOOTING When the system is not proportioning, complete the following steps: 1. Check the balance pointers on the duplex gauge: RED is water, BLACK is foam concentrate. Pointers should be within ± 4 psi (0.28 bar) of each other. 2. When testing the unit, sufficient time is not allowed for the foam solution to reach the foam making device. It takes a minimum of 15 seconds to achieve complete balancing. 3. The pressure control valve on the return line to foam concentrate tank is not properly adjusted for pressure. 4. Make certain that all valve handles are in the NORMAL operating position. 5 The pump is not running or incorrectly wired. Only qualified personnel should perform service to electrical components. 6. The pump is rotating in the wrong direction. Reverse the two power leads to the 3-phase motor to change the rotation direction. 7. The foam tank suction valve is closed. Make certain the strainers are not blocked. Check the compound pressure gauge; if the gauge indicates a vacuum reading, blockage exists between the pump and foam concentrate tank. When the system has a low percentage of injection, complete the following steps: 1. Make certain the duplex gauge pointers balance within ± 4 psi (0.28 bar) of each other. 2. The pressure control valve on the return line to the foam concentrate tank is not properly adjusted for pressure. 3. The partial blockage of strainers (if equipped). Check for a vacuum reading on the compound pressure gauge at the inlet to pump. 4. The foam concentrate valve and automatic foam concentrate valve to the other in-line balanced pressure proportioner on the system is open. When the system has two or more proportioners, make certain the valves to proportioners not being used are fully closed. 5. The pump is not operating at full capacity. Refer to the manufacturer s instructions provided with the foam concentrate pump. 6. The proportioner orifice diameter is incorrect. 7. The foam concentrate is not correct for the system design. 8. Check the foam tank suction valve, concentrate valve and automate concentrate supply valves to spool valves; valves are not in proper operating position. 9. Disconnect the sensing line and remove the threaded end caps of the spool valve. Remove the spool piece with a wooden dowel or other object that will not result in damage. Examine the o-rings on the spool piece, the surface of the spool piece, and the internal bore of the spool valve for damage (scoring or gouges). Lightly coat the o rings with Dow Corning silicone (#4 or #111). Reinstall and examine the spool piece for free movement (a slight drag will persist). Reinstall the end caps and reconnect the sensing line. When the system has a high percentage of injection, complete the following steps: 1. Make certain the duplex gauge pointers balance. 2. The water supply flow is on the low-end range of the proportioner nominal flow range causing a rich foam injection percentage. 3. The proportioner orifice diameter is incorrect. 4. If equipped, make certain the manual foam balancing valve is fully closed. 5. The pressure control valve is set too high: Set to approximately 15 psi (1.03 bar) more than the highest flowing water pressure. 6. Disconnect the sensing line and remove the threaded end caps of the spool valve. Remove the spool piece with a wooden dowel or other object that will not result in damage. Examine the o-rings on the spool piece, the surface of the spool piece, and the internal bore of the spool valve for damage (scoring or gouges). Lightly coat the o rings with Dow Corning silicone (#4 or #111). Reinstall and examine the spool piece for free movement (a slight drag will persist). Reinstall the end caps and reconnect the sensing line. Should the above steps not correct the problem, contact Tyco Fire Protection Products, Technical Services, Marinette, Wisconsin

28 SECTION 6 FLOWMAX PPW PROPORTIONERS PAGE 6-2 REV JAN-11 Balanced Pressure Proportioners DESIGN (Continued) FLOWMAX PPW Proportioners function by maintaining equal pressures in the foam concentrate and water inlets to the proportioner. This balancing ability allows the proportioner to be used over a wide range of flows and pressures. The proportioning device will also respond quickly to changes in the water inlet conditions. The system operates by passing the foam concentrate from a positive displacement pump through a pressure balancing (diaphragm) valve. The diaphragm valve senses the pressures in the foam concentrate and water lines and balances these pressures. The foam concentrate then enters the proportioner. An orifice in the proportioner, and variable geometry cone sized for the foam concentrate type, regulates the flow of pressurized foam concentrate entering the water stream. Up and Downstream Piping Requirements! CAUTION For proper mixing of the concentrate into the water supply, install the proportioner with the required minimum straight pipe lengths of the same nominal diameter before and after the proportioner. Before the proportioner (upstream), there must be straight pipe that is 5 times the proportioner nominal diameter. After the proportioner (downstream), there must be straight pipe that is 2.5 times the proportioner nominal diameter. Maximum Equivalent Length of Concentrate Piping There is no maximum equivalent length for FLOWMAX PPW Proportioners. The maximum equivalent length is that which will allow the foam concentrate pressure, from the foam pump, at entry to the diaphragm valve to be 15 psi (1.03 bar) higher than the maximum water pressure at the water inlet to the PPW. Concentrate Type The operation of a FLOWMAX PPW Proportioner is similar to a FLOWMAX CL Proportioner with an added diaphragm valve to balance the incoming pressure from the foam concentrate pump. FLOWMAX PPW Proportioners have only been tested and listed for use with ANSULITE 3% AFFF (AFC3B) and ANSULITE 3x3 AR-AFFF (A334-LV) foam concentrates. Flow Range Nominal flow ranges for FLOWMAX PPW Proportioners are noted in the ANSUL FLOWMAX PPW Variable Range Proportioners data sheet (Form No. F , latest revision). Operating Pressure The operating pressure for all FLOWMAX PPW Proportioners is a maximum water pressure of 250 psi (17.2 bar) and a minimum water pressure of 30 psi (2.07 bar). However, standard bladder tanks are rated for a maximum water pressure of 175 psi (12 bar). Specially designed bladder tanks for higher pressures are available. Refer to the ASME nameplate on the tank for maximum design pressure.
