CAUTION

CAUTION

WARNING

Drain all water and relieve all pressure from the tank before operating any valves or the sight gauge. Do not put your face in front of valve outlets or near the sight 9'auge tube wh~le. operating: • . Failure to comply may 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.

Maximum working pressure for the Ansul bladder tank is 175 PSI (l,206 kpa).

ASME Code requires over-pressure protection prior to placing this vessel in service. Ansul has not provided over-pressure protection with this vessel. It shall be the responsibility of the owner to arrange for such over pressure problem.

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 Ansul Fire Protection, Foam Business Development Group, Marinette, Wisconsin 54143.

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 the tank nameplate. Overfilling may result in bladder damage.

The tank may be under pressure at this time. Do not place your face or body in front of the valves as injury may result.

SYSTEM OPERATION SECTION

System Stand-By Mode of Operation

The AFFF system valves should be placed in the following positions during normal stand-by periods to ensure the system is ready for operation. All system tank trim valves are 1/4 tum ball valves. The valves are closed when the handle is perpendicular to the pipe and open when the handle is in line with the pipe.

Tank maintenance water chain valve (4A): closed Foam concentrate chain valve (4B): closed Foam fill and vent valve (4C): closed Tank shell vent valve ( 4D): closed Tank water inlet valve (SA): open Foam outlet valve (5B): open Sight gauge isolation valve (6): closed Water supply valve ( 18): closed

The AFFF system discharge directional valves are electrically actuated butterfly valves (with manual override capability). Those valves should be in the follmvi..ng position during normal stand-by periods to ensure the system is ready for operation.

Hose reel discharge valve - Propulsion Motor Room (20A): closed Nozzle discharge valve - Generator Room (19): closed Hose reel discharge valve - Generator Room (20B): closed

System Activation

The foam system is designed for discharge of foam solution through either fixed nozzles in the bilge of the Generator Room, or strategically located hose reel handlines for protection of the Generator Room area or the Propulsion Motor Room area.

Perform the necessary steps to start the applicable water pump designated for the foam system.

At the designated remote control station, operate the applicable manuaVelectric switch to open the water supply valve. That action allows water to flow through the foam tank water inlet valve (5A) and pressurize the bladder, pushing from concentrate liquid out through the foam outlet valve (5B) and into the proportioner (2).

1(EV-}

After opening the water supply, operate the applicable manuaVelectric switch to open one ( 1) of the following:

The 3" nozzle discharge valve (19). That action directs the solution flow to the fixed nozzles in the Generator Room bilge area.

The 2" hose reel discharge valve (20A). That action directs the foam solution flow to the two (2) hose reel stations for protection of the Propulsion Motor Room area.

The 2" hose reel discharge valve (20B). That action directs the foam solution flow to the two (2) hose reel stations for protection for the Generator Room area.

If hose reel handlines are to be used for fire extinguislunent, proceed to the desired hose reel station and follow standard shipboard firefighting procedures. -

To cease operation of the foam system, close the appropriate nozzle discharge valve ( 19), or the appropriate hose reel discl1arge valve (20A or 20B), then close the water supply.

Prior to refilling the foam concentrate tank. perform system flushll~g in accordance with the applicable procedures listed in this manual under Maintenance.

INTRODUCTION

'"his manual is designed to serve as a guide to inspection .>rocedures for ANSULITE concentrates and premix solutions. ANSULITE concentrates are available as 1 %, 3%, 3% freeze-protected, 6% and ARC 3 or 6%.

The designated inspector should be a responsible and experienced person with a sound, basic knowledge of fire equipment hardware and extinguishing agents. A thorough briefing on the procedures to be followed should include the need for precise execution of each step in each test.

Any deviation from the indicated results of a given test may mean that the solution must be replaced. If there Is any doubt, contact your Ansul representative.

A sample form is included within this booklet for use in recording ANSULITE AFFF test results. Note that the form calls for Initial test data. This information Is Important and required as a reference point for future tests.

Frequency And Accuracy Of Tests

Separate tests are required for the concentration and premix solution of ANSULITE AFFF. Ansul recommends that premix solutions be inspected annually and that the concentrates be inspected once every five years. If you should question the quality of your ANSULITE AFFF due to improper mixing, storage, etc., the tests should be performed more frequently.

Most of the tests require that certain properties, such as refractive Index, expansion ratio, etc., be measured and compared with acceptable values. To minimize small variations in the results, it is recommended that all tests, cixoept for Quality of Sample, be performed in triplicate and hat the results be averaged. This average value is then compared with the recommended values contained in this manual.

Storage Conditions

ANSUL recommends that its ANSULITE AFFF concentrate and premixed solutions be stored at the temperatures indicated below in Table 1.

Tests have been conducted with t he concentrate and premix solutions stored at 150° F (65.5° C) with no adverse effect. However, the Underwriters Laboratories Standard No. 162 requires that the maximum storage temperature be listed at 120° F (48.9° C).

Storage of t he concentrates below 35° F (1.7° C) could result in f reezing of the agent except for ANSULITE 3% F.P. Should the agent freeze, it should be thawed at or near room temperature and then agitated or stirred to ensure that the concentrate is a homogeneous solution. Should you suspect t he agent was frozen in the past, agitation will again ensure a homogeneous solution.

TABLE 1

ANSULITE AFFF Concentrate - (Test Procedures Found on Pages 3 - 7)

The concentrate as received from Ansul may be stored in the or iginal container or in a concentrate tank, at the temperatures indicated in Table 1. Ansul recommends that the ANSULITE AFFF concentrate be test ed once every five years or more frequently if adverse storage conditions exist.

The testing as described in this man'l.1al consists of verifying t he ANSULITE AFFF concentrates conform to the requirements l isted in Table 2.

ANSULITE AFFF Premix Solution - (Test Procedures Found on Pag~s 12-16)

As with t he concentrate, the premix solution should be stored at temperatures of 35• F (1 .1• C) or 120• F (48.9• C).

When the premix solution is originally formulated, a sample of the water should be taken and observed for residue. Let the water stand in its container for 5 minutes and then record the amount and appearance of any residue on the inspection sheet to avoid unnecessary concern during future premix inspections. You should also measure and record the ini tial refractive index of the premix solution as described on Page 9 of this manual.

Ansul recommends that the ANSULITE AFFF premix be tested annually or more frequently if adverse storage conditions exist. These tests consist of observing the appearance and measuring the concentration, sealability and expansion ratio of the premix. Observe all instructions carefully when performing the tests.

TEST PROCEDURES- "ANSULITE" AFFF CONCENTRATE

nsul recommends that ANSUUTE AFFF concentrate be .nspected every five years. Should the quality of the ANSULITE AFFF concentrate be questioned for any reason (improper mixing, sediment, . improper storage, temperatures, etc.) It is recommended that the tests be performed immediately. An Inspection Sheet (Ansul Form No. F-7880) is available for recording all test data.

Initial Inspection

When first putting the ANSULITE AFFF concentrate into service, it is recommended that the following be recorded:

1. Concentrate Refractive Index

2. Quality of Concentrate Sample

3. Lot or Batch Number of the Concentrate

Initially the refractive index of the concentrate should be measured. The procedure is described on Page 9 of this manual. By submitting the concentrate's batch number to Ansul Fire Protection, the initial refractive index can be obtained. Determination of the Quality of Concentration Sample is described on Page 8. Both of the above test results should be recorded on the inspection sheet.

ANSULITE AFFF Concentrate

Quality of Sample

1. Remove lid from ANSULITE AFFF concentrate container.

' Stir solution vigorously for 30 seconds using a non· metallic rod, or shake container.

3. Use only clean, dry apparatus to extract and contain solution sample. If doubtful, clean apparatus with detergent (Alconox), rinse well and dry.

4. Extract a small amount of liquid from a depth of at least 6 inches (15.2 cm) below liquid level and replace container lid .

Periodic Inspection

As described on Pages 8-10, the periodic inspections will involve the following tests:

1. Quality of Sample

2. Measurement of Refractive Index

If the concentrate successfully passes these two tests, it is acceptable. Should the sample fail either of these two tests, Ansul then recommends that the following tests be performed to ensure the sample is acceptable (Pages 5-7).

1. Measurement of Film Formation and Sealability

2- Measurement of Expansion

Quality of Sample (Continued)

) 5. Let the sample sit for about five minutes, then examine for stratification, sediment, or sludge. If more than 1 % by volume of sediment or sludge is found, it may be necessary to replace the concentrate.

6. If the sample evidences unacceptable levels of sludge or sediment in Step 5, return to the concentrate container and repeat Steps 2 through 5 to verify your findings. Continue with the Test Procedures which follow.

Measurement of Refractive Index•

This test should be performed three times, with the result averaged to obtain the figure for the Field Inspection Record entry.

1. Hold your TS Meter•· in a horizontal position, swing the cover plate over the body of the instrument to expose both the prism and the cover plate surface (clean if required) and place a small concentrate sample on the measuring prism. NOTE: Use a plastic pipette to minimize the possibility of scratching the prism surface by the contact with the pipette tip.

2. Swing (close) the cover plate over the measuring prism without delay to assure minimum evaporation.

CAUTION: Take care to avoid lifting the cover plate before the reading is made. Care must be taken to avoid air bubbles when placing sample on the refractometer prism.

3. To hold the instrument for reading, place middle finger on nameplate and press the plastic cover gently but firmly to spread a minimal volume of sample in a thin, even layer over the prism. Expose it to an illuminating source such as a fluorescent or incandescent lamp or full sunlighL NOTE: To obtain the optimum contrast between light and dark boundary, the instrument may have to be properly tilted with respect to the lamp.

4. Bring the scale seen in the eyepiece into best focus by rotation of the eyepiece. NOTE: This setting need not be changed as long as the same individual continues to use the instrument. Make the reading on the appropriate scale at the point where the dividing line between bright and dark fields crosses the scale. The average value obtained from three tests must be within ± 0.15% of the initial refractive index.

" This procedure is essenl ially idenlical to that given in " lnstrucl ions for Use and Care of the AO TS Meter and Concenlrim ete('· by lhe American Optical Corporation, Scienlific lnstrumenl Division, Buffalo. New York , 142 15. The TS me1er is available from scienlific supply companies such as Rascher·Be1zold or Curlin Scienlifrc at a cost ot about $500.

· " The TS me1er is compensa1ed to give correct readings d irec tl y on aqueous solutions al all ;empera1ures ranging from so· F to 100· F (15.s· c to 31.s· C).

5. Use a soft cloth or soft tissue (moisten one end with lukewarm water) for wiping the prism clean and dry. If the prism surface or cover plate is not well cleaned before the next sample is loaded, an erroneous or fuzzy reading may result. CAUTION: Do not immerse the eyepiece of the black focusing ring in water. Never use gritty cleaning compounds to clean the prism and never expose the instrument to temperatures above 150° F (65.6° C).

6. If the Quality of Sample and the Refractive Index Tests are okay, no further tests are needed. However, questionable results on either test indicate that the concentrate may not be acceptable. If the concentrate fails either of the above two tests, it is necessary to measure the film formation, sealability and expansion ratio as described in the following sections. If the concentrate passes these additional tests, it is acceptable and need not be replaced.

Measurement of Film Formation and Sealability Quality*

It is not necessary to perform this test unless irregularities are encountered in the Quality of Sample or Measurement of % Concentration Tests.

1. You will need an automatic blender for use as a test foam maker (at 70° ± 5° F or 24° C ± 2° C); an 80-mesh conical screen or corrosion-resisting steel (5 inches (15.2 cm) in height by 43/4 inches (12.1 cm) in diameter); a corrosion-resisting 1000 ml graduated measure (4V2 inches (11.4 cm) in diameter, 5 inches (15.2 cm) deep) with small metal clips fitted at the top edge to restrain the screen from floating out of the container during the test; a corrosion-resisting 100 ml graduated measure, a stopwatch; and a flame source (see Step No. 6). In lieu of the blender to generate a foam sample, a small sample of foam can be discharged through the system's foam nozzle.

2. Pour a carefully measured 600 ml of 98 per cent cyclohexane into the 1000 ml capacity graduated measure.

3. Prepare a premix solution from the concentrate and place a 100 ml sample in the blender. Run the blender at low speed for about 10 seconds to generate foam or generate the foam sample by discharging a small amount of solution from the system's nozzle.

4. Pour 200 ml of this foam onto the fuel surface.

J

Measurement of Film Formation and Sealability Quality (Continued)

5. Insert the screen into the measure, clip firmly into place and start your stopwatch.

6. After 1 minute of elapsed time, pass a small 1-lnch (2.5

cm) long flame several times around the fuel surface at a height of V2 inch ( ± 1/8 inch). A small flash may occur but no sustained ignition shall result if an effective vapor-seal is present. Sustained ignition means the solution should be replaced. NOTE: A hand· held propane tank wi th a capillary tubing outlet and adjustment valve will readily provide a 1-inch long pilot flame.

Measurement of Expansion

It is not necessary to perform this test unless irregularities are encountered in the Quality of Sample or Measurement of % Concentration Tests.

1. Extract at least 10 ml of solution from the premix solution prepared earlier.

2. Place precisely 10 ml in the clean 100 ml graduated cylinder.

3. Place stopper in graduate, placing thumb over top of stopper.

4. Shake graduate in 90° arc, hard and rapidly at least 25 times. If any liquid is in evidence below foam bulk, res hake.

TEST PROCEDURES- "ANSULITE" AFFF CONCENTRATE

5. Push foam clinging to sides of graduate down into foam bulk with a spatula and read volume at top level of foam.

6. Total volume of less than 40 ml corresponds to a foam expansion of less than 4, meaning solution must be replaced.

TEST PROCEDURES - PREMIXED "ANSULITE" AFFF

Ansul recommends that premixed solutions be inspected annually. Should the quality of the ANSULITE AFFF solution be questioned for any reason (improper mixing, sediment, improper storage temperatures, etc.) it is recommended that the tests be performed immediately. An Inspection Sheet (Ansul Form No. F-7880) is available for recording all test data.

Initial Inspection

When first putting an ANSUUTE AFFF premix system into ;ervice, it is recommended that the following measure ments be taken:

1. Measurement of concentrate refractive index

2. Generation of the refractive index versus per cent con centration curve

3. Determination of quality of water

The procedure for determining concentrate refractive index is described on Page 9-10. By submitting the concentrate's batch number to Ansul Fire Protection, the initial refractive index can be obtained. The generation of the refractive index versus per cent concentration curve is illustrated on Page 17.

ANSULITE AFFF Premix Soliution

Quality of Sample

1. Remove fill cap from ANSULITE AFFF solution tank.

2. Stir solution vigorously for 30 seconds using a non metallic rod.

- .. Oml

Determining water quality consists of examining a sample of the water for residue and/or sediment. Let the water stand In its container for 5 minutes and then record the appearance and amount of any residue. This should help you avoid unnecessary concern with the same residue during future premix inspections.

All three of the above test results should of course, be recorded on the inspection sheet. · Periodic Inspection

As described on Pages 13-16, the periodic inspections will involve the following tests:

1. Quality of Sample

2. Measurement of Per Cent Concentration

3. Measurement of Film Formation and Sealability

4. Measurement of Expansion

Quality of Sample (Continued)

3. Use only clean, dry apparatus to extract and contain solution sample. If doubtful, clean apparatus with detergent (Alconox), rinse well and dry.

4. Extract 1 quart of solution from a depth of at least 6 inches (15.2 cm) below liquid level and replace f ill cap.

5. Let the sample sit for about five minutes, then look for stratification, sediment or sludge. If more than 1 % by volume of sediment or sludge is found, you shou ld replace the premix solution. However, any sludge or sediment that was introduced with the water, in t he premixing process, may be disregarded. Refer to your records for information about the sludge o r sediment content of the water originally used.

6. If the sludge or sediment content of the sample is found to be unacceptable, clean all t he sampling equipment carefully and repeat Steps 2 through 5 to verify your findings.·

Measurement of % Concentration

The test should be performed three t imes, with the result averaged to obtain the figure for the Field Inspection Record entry.

1. Hold your TS Meteru in a horizontal position, swing the cover plate over the body of the inst rument to expose both the prism and the cover plate surface (clean if required) and place a small sample of the premix solution on the measuring prism. NOTE: Use a plastic pipette to minimize the possibility of scratching the prism surface by the contact with the pipette tip.

2. Swing (close) the cover plate over the measuring prism without delay to assure minimum evaporation.

CAUTION: Take care to avoid lifting the cover plate before the reading is made. Care must be taken t o avoid air bubbles when placing sample on the refracto meter prism.

3. To hold the instrument for reading, place middle finger on nameplate and press the plastic cover gently but firmly to spread a minimal volume of sample in a thin, even layer over the prism. Expose it to an illuminating source such as a fluorescent or incandescent lamp or full sunlight. NOTE: To obtain the opt imum contrast between light and dark boundary, the instrument may have to be properly tilted with respect to the lamp.

4. Bring the scale seen in the eyepiece into best focus by rotation of the eyepiece. NOTE: This setting need not be changed as long as the same individual continues to use the instrument.

5. Make the reading on the appropriate scale at the point where the dividing line between bright and dark fields crosses the scale and .use the appropriate con centration graph to convert readings to per cent con centration. This graph was generated when the initial inspection was performed. (The procedure is described on Page 12.) If the average of the three refractive index readings is not within ± 1 % of refractive index anticipated (from the appropriate graph and the initial inspection figures of the Field Inspection Record) additional tests will be required to verify the accept ability of the ANSULITE AFFF premix solution.

6. Use a soft cloth or sott tissue (moisten one end with lukewarm water) for wiping the prism clean and dry. If the prism surface or cover plate ls not well cleaned be fore the next sample is loaded, an erroneous or fuzzy reading may result. CAUTION: Do not immerse the eye piece or the black focusing ring in water. Never use gritty cleaning compounds to clean the prism and never expose the instrument to temperatures above 150° F (65.6° C).

Measurement of Film Formation and Sealability Quality•

This test should be performed three times, with the result averaged to obtain the figure for the Field Inspection Record entry.

1. Equipment required to conduct the test includes an automatic blender for use as a test foam maker (at 70° ± 5° For 24° C + 2· C); an 80-mesh conical screen of corrosion-resisting steel (5 inches (15.2 cm) in height by H~ inches (12.1 cm) in diameter); a 1000 ml corrosion-resisting graduated measure (4112 inches (11.4 cm) in diameter, 5 inches (15.2 cm) deep) with small metal clips fitted at the top edge to restrain the screen from floating out of the container during the test, a corrosion-resisting 100 ml graduated measure, a stopwatch, and a flame source (see Step No. 6). In l ieu of the blender to generate a foam sample, a small sample of foam can be discharged through the system's foam nozzle.

2. Pour a carefully measured 600 ml of 98 per cent cyclo hexane into the 1000 ml capacity graduated measure.

Sustained ignition means the solution should be replaced. NOTE: A hand held propane tank with a capillary tubing outlet and adjustment valve will readily provide a 1 inch (2.5 cm) tong pilot flame.

Measurement of Expansion

This test should be performed three times, with the result averaged to obtain the figure for the Field Inspection Record entry.

1. Extract at least 10 ml of the premix solution from one quart sample previously removed from tank.

2. Place precisely 10 ml in the 100 ml graduated cylinder.

3. Place stopper in graduate, placing thumb over top of stopper.

4. Shake graduate in 90° arc hard and rapidly at least 25 times. If any liquid is in evidence below foam bulk, reshake.

5. Push foam clinging to sides of graduate down into foam bulk with a spatula and read volume at top level of foam.

6. Total volume of less than 40 ml corresponds to a foam expansion of less than 4, meaning solution must be replaced.

USING THE REFRACTIVE INDEX CURVE TO DETERMINE PREMIX CONCENTRATION AND TO CHECK PROPORTIONING

ACCURACY

Developing the Refractive Index Versus Concentration Curve

The refractive index of an ANSULITE AFFF solution can be used to determine premix concentrations or to check the accuracy of proportioning equipment. Measurement of the refractive index allows you to determine the per cent ANSULITE AFFF concentrate in solution with either fresh or salt water. The higher the concentrate level, the higher the refractive index. In fact, a straight line relationship exists between refractive index and per cent ANSULITE AFFF concentration.

The refractive index is measured with the use of a refractometer, such as the hand-held AO TS Meter and Concentrimeter, manufactured by the American Optical Corporation, Scientific Instrument Division, Buffalo, NY 14215. This TS meter is available from many scientific supply companies at a cost of about $500. In lieu of purchasing the instrument, many local laboratories will have bench models for determining refractive index.

Prior to mixing the premix solution or checking proportioner accuracy, it will ·be necessary to plot a refractive index versus concentration curve. Since the refractive index will vary somewhat with water type, it is important that this curve be based on water taken from the same source used for your premix solution or your proportioner.

Plotting the Refractive Index Versus Concentration Curve

1. The following equipment will be required:

AO TS meter (refractometer) 100 ml graduated cylinder

/ Medicine dropper Soft cloth or soft tissue 15 - 25 ml of your ANSULITE AFFF concentrate Sample of water used for premix or proportioning Grid for plotting the curve such as the one given on the back of the "Field Inspection Record" at the end of this manual Stirring rod

2. To plot the curve select a proportioning range (3 or 4 points) which will cover concentrations both below and above the correct concentration for the ANSUUTE concentration which you are using. For example, if you are using ANSULITE 3% concentrate you will want to make ANSULITE/water solutions to cover proportioning both below and above the proper proportioning eoncentration of 3%. Therefore, for a 3% concentrate, you will want to make up ANSULITE/water solutions of 0%, 2%, 3% and 4%. The refractive index for each of these solutions will be determined and plotted on the refractive index versus concentration graph. The line connecting these points is the curve which will be used to check your premix concentration or proportioner accuracy. This curve should be kept on file with the "Field Inspection Record''. Consult Figures 1 through 5 on Page 7 to determine what proportioning range you .

should use for your particular ANSULITE foam concentrate .

. · 3. To prepare the ANSULITE/water solutions add the .

proper volume of ANSULITE concentrate v:'ith the waler which you will be using in the premix or the proportioned system. For example, to prepare a 2% (by volume) solution mix 2.0 ml of the ANSULl'TE concentrate with 98.0 ml of your water. This will give you 100 ml of a 2% ANSULITE/water solution. To make a 3% (by volume) solution mix 3.0 ml of the ANSULITE concentrate with 97.0 ml of your water. This will give you 100 ml of a 3% ANSUUTE/water solution. A 6% (by volume) solution Cqn be made by mixing 6.0 ml of the ANSULITE concentrate with 94.0 ml of your water to give you 100 ml of a 6% ANSULIJE/water solution.

Use this general scheme to prepare any solution concentration you wish. Be sure that your measuring and mixing devices are thoroughly cleaned between each ANSULITE/water solution you make up.

4. On your TS meter measure the refractive index of each ANSULITE/water solution you make. Three measure ments should be made and the results averaged. This averaged refractive Index value should then be plotted on the curve which you are making.

Proportioning Accuracy and Calibration

Once the refractive index versus concentration curve is developed, it is a simple matter to calibrate or check the accuracy of your proportioner.

With the proportioner operating, withdraw a sample of foam solution downstream of the proportioner. Measure the refractive index of this solution with the refractometer as described on Pages 12-13. As before, it is a good idea to make three measurements and average the results.

Using your refractive index versus concentration curve draw a vertical linen through the measured refractive inde~ value on the horizontal axis to the point where it crosses your curve. Then draw a horizontal line across from this point so it intersects the vertical axis. The concentration read at this intercept is the per cent concentration of ANSULITE AFFF concentration-to-water proportioned by your system.

Detennining Premix Concentration

The procedures for determining premix concentration are described· on Pages 8 - 9. Note that the refractive Index versus concentration curve should be constructed when the premix solution is originally formulated.

Introduction

Depending on the equipment provided, two methods are accept able 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 opera tion. The approximate quantity of gallons Oiters) required to refill the bladder can be determined by subtracting the table reading ("Concentrate In Tank") from the capacity specified on the tank nameplate:

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.

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.

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 fill ing the tank with the exact amount of concen trate as specified on the tank nameplate. The full level can then be verified following tank refills or during inspection and maintenance procedures.

6. Open Water Inlet Valve.

7. Close Tank Shell Drain Valve and Tank Shell Vent Valve.

8. Using the measurement recorded in step 4, refer to the cor responding measurement table to determine the approxi mate gallons (l) contained within the bladder. The Table of Contents lists the measurement table page numbers ac cording to tank size and type.

~~A~IJREMENT PROCEDURES

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 con siderations make it practical. The rod must be no larger than 112 in. (12 mm) in diameter and must be long enough to reach from the top of the Bladder VenUFill Valve to the bottom of the tank. Marking 1 inch (2.5 cm) increments on the rod will simpli fy 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.)

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 blad der as shown in Figures 2 and 3.
