004293 004327 VERTICAL AND HORIZONTAL BLADDER TANKS Filling and Maintenance Manual

INTRODUCTION This manual is intended as a guide for both the ANSUL Vertical Bladder Tanks and Horizontal Bladder Tanks. If there are any questions, or further information is required, contact Tyco Fire Protection Products, Applications Engineering, Marinette, Wl 54143-2542. Those who design, install, operate, refill, inspect, or maintain these systems should read this entire manual. IMPORTANT This equipment is designed for use on only Class A Fires and Class B Hydrocarbon Fires. Bladder tanks are mechanical devices. They need periodic care. Inspections provide reasonable assurance that the bladder tank is full and the system is operable. Inspection should take into consideration the environment, system use, and user inspection policy; but as a minimum should be conducted semi-annually. 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.! WARNING Maximum working pressure for an ANSUL bladder tank is 175 psi (12.06 bar). ASME Code requires over pressure protection prior to placing this vessel in service. Tyco Fire Protection Products has not provided over pressure protection with this vessel. It shall be the responsibility of Owner to arrange for such over pressure protection. Note: Tyco Fire Protection Products has not provided an over pressurization device because the water supply pressure and flow capacity of your fire protection system and the details of the complete system design must be known before an over pressure protection device can be provided. Therefore, the owner or the engineer designing the fire protection system shall have the responsibility of determining and arranging for the type of over pressure protection that should be provided for this vessel as part of the fire protection system. If additional information or assistance is required, please contact your fire protection system engineer.! CAUTION Do not weld on the bladder tank. The tank contains an elastomeric bladder and interior protective coating which will be destroyed by welding temperatures. For additional information contact Tyco Fire Protection Products, Applications Engineering, Marinette, Wl 54143-2542. Because the foam concentrate will undergo thermal expansion as the temperature increases, it is important, that at the time of filling, the temperature of the concentrate be as close as possible to the actual ambient temperature where the tank will be located. NOTICE ANSUL Foam Concentrates must be stored within the temperature range listed on the tank nameplate. If the concentrates require storage outside of these temperature ranges, consult Tyco Fire Protection Products, Applications Engineering, Marinette, Wl 54143-2542. Also, particular attention should be given to the Field Inspection Manual (Part No. 31274) which deals with the testing procedures for ANSUL Foam Concentrates.! CAUTION Lifting lugs are designed to lift the tank empty while utilizing two lift lugs on vertical tanks and four lift lugs on horizontal tanks. The angle of the rope or chain from horizontal must be 30 degrees or greater. 008397

INSTALLATION Page 5 INSTALLATION To prepare the bladder tank for placement in service: 1. Remove all cord, wrapping, and banding ties. Examine entire system and component parts for concealed shipping damage before placement or securement on site. 2. NOTICE If the bladder tank is to be connected to a Closed Head Sprinkler System, contact Tyco Fire Protection Products, Applications Engineer ing, Marinette, Wl 54143-2542. NOTICE For bladder tank dimensions, refer to Vertical and Horizontal Bladder Tank Data Sheet (Form No. F-83179).! CAUTION Lifting lugs are designed to lift the tank empty while utilizing two lift lugs on vertical tanks and four lift lugs on horizontal tanks. The angle of the rope or chain from horizontal must be 30 degrees or greater. 3. Anchor system to floor and remove plastic shipping plugs from bladder tank valves.! CAUTION Do not weld on the bladder tank. The tank contains an elastomeric bladder and interior protective coating which will be destroyed by welding temperatures. For additional information contact Tyco Fire Protection Products, Applications Engineering, Marinette, Wl 54143-2542. 4. Install foam proportioner in main distribution supply pipe to discharge device(s). NOTICE The proportioner must be mounted at the same elevation as the top flange of the tank or a normally-closed valve (manual or automated) must be installed in the foam concentrate line to prevent agent migration. A concentrate isolation valve is required to isolate the tank during filling procedures. 5. Install piping from water supply upstream of proportioner (see Figures 3 and 4) and to the bladder tank water inlet using the appropriate piping, valves, gauges, unions, etc., as determined by the system design engineer.! WARNING Maximum working pressure for an ANSUL bladder tank is 175 psi (12.06 bar). ASME Code requires over pressure protection prior to placing this vessel in service. Tyco Fire Protection Products has not provided over pressure protection with this vessel. It shall be the responsibility of Owner to arrange for such over pressure protection. Verify that over pressure protection has been provided for this vessel within the fire protection system. If additional information or assistance is required, please contact the fire protection system design engineer. 6. Install piping from the bladder tank foam concentrate outlet to the proportioner concentrate inlet using appropriate piping, valves, strainers, check valves, unions, etc., as determined by the system design engineer. 7. If an optional sight gauge is provided, install gauge by completing the following steps: a. Remove plug from tee located adjacent to the Bladder Drain/Fill Valve near the bottom of the tank. (See Figure 1 or 2.) b. Screw sight gauge assembly into tee using Teflon tape on male threads of nipple. c. Snap end of support into adapter located on side of tank. HYDRAULIC ACTUATED BALL VALVE INSTALLATION / OPERATION The hydraulic actuated ball valve requires pressure to open. There are two 1/8 in. ports on each actuator, one is labeled in and the other is unlabeled. Most valve sizes use a single actuator, but some larger valves use a twin actuator assembly. With the ball valve in the closed position, the actuation piping is piped to the in port(s); the vent port(s) is left open to allow air pressure to be relieved as the internal piston is pushed over by the water pressure. The actuator has to be manually reset by relieving the actuation water pressure and with a wrench manually turning the indicator stub back to the closed position. If the in label has been removed, with the valve in the closed position, put a finger over both ports and manually open the valve with a wrench. The port(s) that is pulling a suction is the port(s) to pipe the actuation piping to. Remember the vent port(s) must be left open to atmosphere and not plugged, otherwise the valve will not open.

AUxILIARY FILLING EQUIPMENT Page 6 The following equipment is not supplied by Tyco Fire Protection Products, but is required for Initial Fill and Major Refill. (See Figures 3 and 4.) 1. A Wet/Dry shop vacuum with a 2 HP (1.5 Kw) motor or larger. 2. Appropriate pipe fittings and duct tape to connect the vacuum hose to the 1 inch NPT Tank Shell Vent Valve. 3. Concentrate fill pump* capable of 25 GPM (94.6 Lpm) maximum output at 15 psi (1.03 bar), pump suction and discharge hose, a two-position ball valve, and all appropriate fittings for connecting to the 1 inch NPT Bladder Drain/Fill Valve. *ANSUL Bladder Tank Fill Pump (includes suction and clear discharge hose) Part No. 72724, or equal. NOTICE Prior to adding foam concentrate to the tank, its refractive index should be measured and recorded on the Field Inspection Record (see FIeld Inspection Manual), along with a refractive index vs. concentration curve. The procedures for these operations are covered in the Field Inspection Manual (Part No. 31274). It is also required that the batch numbers from the concentrate pails be recorded for future reference.

INITIAL FILL Page 7 To initially fill a bladder tank:! CAUTION Because the foam concentrate will undergo thermal expansion as the temperature increases, it is important, that at the time of filling, the temperature of the concentrate be as close as possible to the actual ambient temperature where the tank will be located. Fill the bladder only to the capacity specified on tank nameplate. Overfilling may result in bladder damage. 4. Connect vacuum hose to shop vacuum and start vacuum. Note the high pitched sound from the vacuum before opening Tank Shell Vent Valve. This will be the same pitch heard in Step No. 6. 5. Open Tank Shell Vent Valve to pull the air out between the bladder and tank shell, which will pull the bladder out to the tank shell wall (see Figure 6). 6. When the change in pitch from the vacuum is heard, this indicates the bladder is now completely pulled out to the tank shell wall. First close the Tank Shell Vent Valve, then turn off the vacuum (see Figure 6). 1. Confirm plastic shipping plugs are removed from all bladder tank valves. 2. Make certain bladder tank valve handles are in the following positions (see Figure 5).

MAINTENANCE Page 15 SUGGESTED FOAM SYSTEM TESTING (BLADDER TANK WITH TEST HEADER) 1. If bladder tanks are not filled, fill per ANSUL Bladder Tank Manual or authorized ANSUL representative s instruction. 2. Prepare required refractive index standards, and generate refractive index curve for testing foam discharge samples. Refer to Field Inspection Manual. 3. Prior to testing, make sure all valves on bladder tanks are in the correct position. All 1 in. vent, fill, and drain valves should be closed. The hydraulic actuated concentrate valve should be closed (1/8 in. connection not used should be left open to vent air). The Concentrate Isolation Valve should be closed. Slowly open the Water Inlet Valve to pressurize tank. 4. Connect hoses to test header. With only water flowing, adjust hose valve to establish the desired system test flow. (Note: Recommended system test flow for closed head system is typically at the low end listed flow rate for the size proportioner being tested.) Shut down system valve without closing the adjusted hose valve, and reset system valve for test actuation. If using a containment truck for the foam solution, attach discharge hoses to truck. A test sample valve (1/4 in. minimum) is required in the discharge piping somewhere between the proportioner and the containment truck. Note: Spraying or pretreating the truck tank with a defoaming agent is recommended to prevent nuisance foaming in the truck tank during testing. 5. Once the bladder tank has been filled and hose valves have been adjusted, one zone is selected for foam discharge. Personnel are required to be stationed at the test sample valve to take samples of foam discharge and at the bladder tank to shut off the foam concentrate once the foam sample is taken. Communication between these two persons is important to minimize concentrate used. 6. Once everyone is in their positions, trip selected zone. Thirty to forty-five seconds after foam appears from the test valve, take a sample of the solution discharge. Shut Concentrate Isolation Valve as soon as the samples are taken. Check refractive index against the standard curve that was made in step #2. If sample is low, retest. When sample tests OK, shut down test valve, and change over to other risers that need to be tested repeating procedure. 7. After system tests are completed, refill bladder tank if required; and return valves to their normal operating positions. On the main tank, the hydraulic valves need to be closed (this has to be done manually). The Water Inlet Valve and the Concentrate Isolation Valves are to be in the open position. On the reserve tank, all valves are to be in the closed position as this is a reserve supply to put the system back in service quickly after a discharge. Note: Containment and disposal of the foam solution is the responsibility of others.

SERVICE AND REPAIR Page 16 The best assurance against system malfunction is proper operation, recharge, inspection, and maintenance. To remedy, as quickly as possible, any disorder that may occur, the following table lists some of the probable irregularities that may develop and gives suggestions for corrective action. To remedy any disorder detected through periodic inspection and maintenance examinations: Component Disorder Corrective Action Bladder Tanks Dents* or Abrasions Hydrostatically test (see ASME plate affixed to tank) and refinish (clean damaged area and repaint, using a compatible primer and finish coat), or replace tank.

SERVICE AND REPAIR Page 17 BLADDER INTEGRITY VERIFICATION PROCEDURE 1. Isolate the bladder tank from the system by closing both the Water Inlet and Concentrate Isolation Valves. Drain water from the tank shell by opening Tank Shell Drain and Shell Vent Valves.! CAUTION Tank may be under pressure at this time. Do not place face or body in front of valves as injury may result. 2. Transfer remaining foam concentrate in bladder to 55 gallon (208 L) drums or some other container. 3. When tank is completely drained, the valves on the bladder tank should be in the following positions: Water Inlet Valve........................ Closed Concentrate Isolation Valve................ Closed Tank Shell Drain Valve.................... Closed Tank Shell Vent Valve.................... Closed Bladder Vent/Fill Valve..................... Open Bladder Drain/Fill Valve.................... Open 4. Using a Wet/Dry shop vacuum of 2 HP (1.5 Kw) minimum, attach the vacuum hose to the Tank Shell Vent Valve. This may be accomplished by using pipe fitting and securing with duct tape. 5. Connect vacuum hose to shop vacuum and start vacuum. Note the high pitched sound from the vacuum before opening the valve. This is the same sound that should be heard in step #7. 6. Open Tank Shell Vent Valve to pull the air out between the bladder and the tank shell, which will pull the bladder out to the tank shell wall. 7. When the change in pitch from the vacuum is heard, this indicates that bladder is now completely pulled out to the tank shell wall. 8. If no change in pitch is noted after about 15 minutes, the bladder is damaged and needs to be replaced. 9. If there is a change in pitch, the bladder is not damaged. Close the Tank Shell Vent Valve and turn off the vacuum. The bladder tank can now be refilled as per the ANSUL Bladder Tanks Filling and Maintenance Manual (Part No. 74177), using the vacuum method. BLADDER REMOVAL & REPLACEMENT PROCEDURES NOTICE Review all steps before beginning procedure. 1. Remove all water from tank shell by opening both the Tank Shell Vent Valve and the Tank Shell Drain Valve. A hose should be connected to the drain valve to direct the flow of water to an approved disposal area. 2. Remove all foam concentrate from the bladder by opening the Bladder Vent/Fill Valve and the Bladder Drain/Fill Valve. A hose should be connected to the Bladder Drain/Fill Valve to direct the concentrate using a transfer pump to an approved disposal containment tank/drums. 3. Remove top and bottom flange from the tank. 4. Slowly remove the vertical center tube out through the top flange opening. This tube must be removed on all horizontal tanks. (If the center tube cannot be completely removed on the vertical tanks, drop the tube through the lower flange opening and remove bladder out through the top flange opening sliding the bladder past the center tube.) 5. Remove end flanges on horizontal tanks and slowly remove the horizontal center tube so as not to damage the bladder. 6. Before removing the bladder, attach cords (ropes) to the flange bolt holes on all ends of the bladder with the exception of the end where the bladder will be pulled out. The cords will also be used for installing the new bladder. After the cords are attached, slowly pull the bladder out of the end that does not have the cords attached. 7. Prior to reinstalling the replacement bladder, mark the bladder flanges to ensure proper alignment once it has been reinstalled. Re-attach the cords on the flange ends to help guide them back into place. Use of duct tape to compress bladder flanges is helpful in reinstalling the bladder. 8. Re-install the bladder and check to ensure that the bladder is properly aligned. Before re-inserting the center tubes, close the Tank Shell Drain Valve and attach a vacuum cleaner hose to the Tank Shell Vent Valve. With this valve open, start the vacuum. This will pull the bladder out toward the tank shell wall. Once the bladder has been sucked out toward the shell wall, look through the flange end to ensure that the bladder is not twisted (if twisted make the adjustment to correct this). Once the bottom flange opening is visible, close the Tank Shell Vent Valve and then shut vacuum off.

SERVICE AND REPAIR Page 18 9. Re-insert the center tubes taking care not to damage the bladder. 10. NOTICE Torque specification below is a maximum. If during torquing of bolts bladder flange appears to become deformed, stop torquing at this point. Only torque bolts further if a leak is present while inspecting during tank pressurization. Re-install the flanges following the procedure for bolting instruction per ASME flange torquing procedures. This is tightening the bolts to 162 ft lb (219.6 N m) each in 1/5 increments using 0-180, 90-270, 45-225, 135-315 degree sequence.

MEASUREMENT PROCEDURES Page 1 Introduction Depending on the equipment provided, two methods are acceptable for estimating the foam concentrate contained within the bladder: (1) Using The Sight Gauge or (2) Using A Dip Stick/Line. Both methods can be used for either vertical or horizontal tanks. Neither of the methods is exact, but both will provide a close estimate of the bladder contents. The measurement tables listed in this guide provide an estimate of the amount of concentrate remaining in the tank after operation. The approximate quantity of gallons (liters) required to refill the bladder can be determined by subtracting the table reading ( Concentrate In Tank ) from the capacity specified on the tank nameplate: Concentrate Concentrate Required Tank Capacity In Tank = To Refill (gallons (L)) (gallons (L)) (gallons (L)) The percentage of concentrate to be replaced can be determined by dividing the number of gallons (L) required to refill the tank by the rated capacity specified on the tank nameplate. If the percentage of concentrate to be replaced is more than 25%, a major refill is required. Otherwise the instructions for a minor refill may be followed (refer to Bladder Tanks Filling and Maintenance Manual, Part No. 70343). Concentrate Required Tank Capacity Percentage (%) To Refill X 100 = of Concentrate (gallons (L)) (gallons (L)) to be Replaced! DANGER Drain all water and relieve all pressure from tank before operating any valves or the sight gauge. Do not put your face in front of valve outlets or near sight gauge tube while operating. Failure to comply will result in personal injury or sight gauge damage due to the unrestricted release of water or concentrate through the valve outlet or into the sight gauge. 4. Measure and record the concentrate depth in the sight gauge tube. The measurement must be taken from the tube connector at top of the valve body to the concentrate level in the sight gauge tube as shown in Figure 1. NOTICE It is also a good idea to mark the full level on the sight gauge tube. Do this after initially filling the tank with the exact amount of concentrate as specified on the tank nameplate. The full level can then be verified following tank refills or during inspection and maintenance procedures. MEASURE CONCENTRATE DEPTH GAUGE USE OPERATING Using The Sight Gauge The following procedures are provided for those tanks that have a sight gauge installed. If a sight gauge is not provided, refer to the Using A Dip Stick/Line section. 1. Close Water Inlet Valve. 2. Open Tank Shell Drain Valve and Tank Shell Vent Valve until all water is drained and all pressure is relieved from tank. NOTICE To obtain an accurate reading, all water must be drained and all pressure must be relieved from tank. 3. Pull ring pin and turn sight gauge valve handle to READ position. Allow concentrate to enter and come to a stable level in sight gauge tube. figure 1 004317 5. Return sight gauge valve to the OPERATING position, insert ring pin, and install visual inspection seal. The concentrate will automatically drain from the sight gauge tube at this time. 6. Using the measurement recorded in Step No. 4, refer to the corresponding measurement table to determine the approximate gallons (L) contained within the bladder. The Table of Contents lists the measurement table page numbers according to tank size and type. 7. If bladder tank capacity is below system requirement, tank must be refilled. Refer to Minor or Major refill procedure in the Bladder Tanks Filling and Maintenance Manual (Part No. 70343). 8. Close Tank Shell Drain Valve and slowly open Water Inlet Valve to vent air between bladder and tank shell. 9. Close Tank Shell Vent Valve.

MEASUREMENT PROCEDURES Page 2 Using A Dip Stick/Line To perform these procedures, the user must supply either a wooden rod or weighted line. A wooden rod is recommended where tank size and space considerations make it practical. The rod must be no larger than 1/2 in. (12 mm) in diameter and must be long enough to reach from the top of the Bladder Vent/Fill Valve to the bottom of the tank. Marking 1 inch (25 mm) increments on the rod will simplify the measurement process. Where tank size and the free space above the tank do not allow for use of a wooden rod, a weighted line can be used. The line must be long enough to reach from the top of the Bladder Vent/Fill Valve to the bottom of the tank. The weight must not be larger than 1/2 in. (12 mm) in diameter. 1. Close Water Inlet Valve. 2. Open Tank Shell Drain Valve and Tank Shell Vent Valve until all water is drained and all pressure is vented from tank. NOTICE To obtain an accurate reading, all water must be drained and all pressure must be relieved from tank. 3. Open the Bladder Vent/Fill Valve and lower the dip stick/line through the valve until it reaches the bottom of the tank. (When using a dip line, it will begin to slacken when the weight has reached the bottom of the tank.) 4. Remove the dip stick/line from the tank. Measure and record the length of the dampened portion of the dip stick/line. This measurement is the depth of the concentrate in the bladder as shown in Figures 2 and 3. DIP STICK/LINE MEASURE CONCENTRATE DEPTH BLADDER VENT/ FILL VALVE TANK SHELL VENT VALVE NOTICE It is also a good idea to mark the full level on the dip stick/line. Do this after initially filling the tank with the exact amount of concentrate as specified on the tank nameplate. The full level can then be verified following tank refills or during inspection and maintenance procedures. DIP STICK/LINE MEASURE CONCENTRATE DEPTH BLADDER VENT/ FILL VALVE TANK SHELL VENT VALVE TANK SHELL DRAIN VALVE figure 3 004319 5. Close Bladder Vent/Fill Valve. 6. Using the measurement recorded in Step No. 4, refer to the corresponding measurement table to determine the approximate gallons (L) contained within the bladder. The Table of Contents lists the measurement table page numbers according to tank size and type. 7. If bladder tank capacity is below system requirement, tank must be refilled. Refer to Minor or Major refill procedure in the Bladder Tanks Filling and Maintenance Manual (Part No. 70343). 8. Close Tank Shell Drain Valve and slowly open Water Inlet Valve to vent air between bladder and tank shell. 9. Close Tank Shell Vent Valve. TANK SHELL DRAIN VALVE figure 2 004318
