1.0 MEANING OF SAFETY SIGNAL WORDS

A safety related message is identifi ed by a safety alert symbol and a signal word to indicate the level of risk involved with a particular hazard. Per ANSI standard Z535.6-2011, the defi nitions of the four signal words are as follows:

DANGER

DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.

WARNING

WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.

CAUTION

CAUTION indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury.

NOTICE is used to address practices not related to physical injury.

NOTICE

2.0 SAFETY

The eductor is designed for Class A and Class B foam concentrates. If you intend to use the eductor for liquids other than Class A and

Class B concentrates and water, we urge you to contact the Task Force Tips Engineering Department. The use of other liquids may void the warranty and subject the user to hazards not addressed in this manual. The user assumes all risks for non-intended uses.

• Make sure there is enough foam concentrate prepared before fi ghting fi re. TFT’s eductors are calibrated 15% more than the nominal rate, or half percent point, which ever is less. Per FOAM EQUIPMENT AND LIQUID CONCENTRATES – UL 162, the liquid concentrate induction rate of a proportioner, expressed as a percentage of the fl ow rate of the mixed water plus concentrate solution, shall be minus zero (0) percent, plus thirty (30) percent of the manufacturer’s specifi ed induction rate or one percent point, whichever is less.

• Make sure the meter head set to OFF position and the correct nozzle and hose lay are securely attached to the eductor before the hose line is charged.

• Make sure the nozzle gallonage matches eductor’s gallonage.

• Make sure the hose lay does not exceed the maximum listed in the operating instruction.

• Make sure that the meter head is set to the correct concentration for the type of foam being used. Foam concentrates can be ineffective if not used at the correct percentage.

WARNING

WARNING

WARNING

WARNING

Lack of foam can place operator at risk of injury or death. Establish foam fl ow before advancing into hazardous situations. Make sure you do not run out of foam concentrate before the task is complete. Check concentrate level periodically and keep an adequate supply on hand.

Do not use Class A foam on Class B fi res or Class B foam on Class A fi res. Note: Some foam concentrates are universal and can be used on Class B fi res and spills and as a wetting agent on Class A fi res. (Refer to foam concentrate manufacturer’s recommendations for proper foam choice.)

Improper use of foam can result in injury or damage to the environment. Follow the foam concentrate manufacturer’s instructions and fi re service training to avoid the following:

• Using the wrong type of foam on a fi re, i.e. Class A foam on Class B fl ammable liquid fi re

• Mishandling of concentrates

• Plunging foam into pools of liquid fuels

• Directing foam onto yourself or other personnel

There is a wide variety of foam concentrates. Each user is responsible for verifying that any foam concentrate chosen to be used with this unit has been tested to assure that the foam obtained is suitable for the purpose intended.

The eductor may be damaged if frozen while containing signifi cant amounts of water or foam.

Such damage may be diffi cult to detect visually, and can lead to possible injury or death. Any time the eductor is subject to possible damage due to freezing, it must be hydrostatically tested by qualifi ed personnel before being considered safe for use.

The eductor proportioning rate ranges from 1/2% to 6%.

TFT’s 350 Series eductors can be used with 1/2% Class A foam concentrate for wildland, rural, and urban fi re suppression on Class

A fuels (wood, paper, combustible materials). On Class A materials, the eductors are intended to be used for direct extinguishment, overhaul, and wetting of fuels. Some foam concentrates are corrosive; we recommend using only Class A concentrates that have received USDA and USFS approval.

On class B materials, the eductors are primarily intended for vapor suppression or extinguishment. They can be used with high viscosity 1%, 3%, 6%, 3x3%, and 3x6% Alcohol Resistant Class B concentrates on fl ammable liquids containing polar solvents.

The eductor can also be used with plain AFFF concentrates rated at 1%, 3% or 6% with various freeze protected foams, and with

FFFP foam types. These foams generally have a lower viscosity than the calibration viscosity of the TFT eductor and will be inducted faster than expected resulting in stronger concentrations. While this does not degrade foam quality, it does reduce the operation time for a given foam supply. Testing should be done with the foam being used to assure accurate induction rate.

Standard inlet operating pressure is 200 psi on all TFT eductors (1400kPa/14 bar), except the low pressure versions marked for 150 psi (1000kPa/10 bar).

3.1 PART IDENTIFICATION (cont)

The eductor can be split into two parts by grasping the locking ring and retracting it fully to separate the metering head from the eductor body. All the foam passageways can easily be inspected. The foam passageway into the eductor contains a free-fl oating check disk with three fi ns. The check disk is pressure activated to keep water from coming out of the fi re hose and back into the foam pail.

The metering head contains a red back fl ush button that can be depressed to open the check disk.

The metering head also has a large proportioning knob that can be rotated to align the ball valve to different detent positions. The

2.5” eductors have fi ve choices: Off, ½%, 1%, 3%, and 6%. Each foam setting has a precision sized metering orifi ce in the valve ball.

The eductor cannot be operated between settings, as the metering orifi ces will not line up properly. The setting of the proportioning knob lines up with the white indicator ball.

3.2 INSTALLATION INSTRUCTIONS

The eductor body is equipped with four 3/8-16, ¾” deep threaded mounting holes. To mount the unit, attach to the desired location using bolts with enough length to provide at lease ½” engagement with the unit. Hole spacing is shown in Figure 3.2.

3.3 GENERAL OPERATING INSTRUCTIONS

1) Choose the appropriate foam concentration (Section 4.0)

2) Lay the appropriate hose line (Section 5.0)

3) Connect the appropriate nozzle (Section 6.0)

4) Charge the hose and open the nozzle fully to establish the water fl ow.

5) Adjust the pump pressure so the eductor inlet is set at pressure specifi ed on body label.

6) Rotate the percentage knob to the desired concentration and put the concentrate intake hose in the foam supply.

3.4 CLEANING INSTRUCTIONS

After use, take the concentrate intake hose out of the foam supply and turn down the pump pressure to below 75 psi (5.2 bar). Shut off the nozzle. Restrain the hose and expect a rapid discharge of water, especially at the 6% setting. Push the red fl ush button and run fresh water through the hose and metering head on each setting until there is no visible foam in the fl ush water.

Retract the lock ring to remove the metering head. Turn off water supply and remove the eductor from the hose so that any remaining foam residue can be washed from the wand, metering head and eductor.

CAUTION

Do not back fl ush above 75 psi. Rapid back fl ush discharge from the wand could cause injury.

The back fl ush push button is pressure activated and must not be forced at pressures over 75 psi (5 bar).

3.5 CONCENTRATE INTAKE HOSE OPTIONS

The eductor is shipped with a 1.25” x 8’ black, industrial grade, UV resistant hose with a 1.0” camlock connection. A 1.25” x 8’ clear, fl exible hose is available as a secondary option. To order, call 800-348-2686 and ask for part # UE950.

A camlock adaptor is available for those who wish to use a hose with a 1.5” female camlock connection. To order, call 800-348-2686 and ask for part #UE960-KIT.

4.0 FOAM SELECTION

Actual foam concentrations vary with changes in water fl ow, foam concentrate temperature and viscosity. The user must verify that the concentrate’s performance is suitable for use in their application. In all cases, the manufacturer’s recommendations must be followed.

CAUTION

Class A foam concentrates are generally less viscous than Class B foam concentrates. Using

1% Class B foam percentage setting to educt Class A foam, may cause the actual Class A foam percentage to be more than 1%.

4.1 CLASS A FOAM

It is recommend that the Class A foam used meets USDA Forest Service 5100-307A “Specifi cation for Fire Suppressant Foam for

Wildland Firefi ghting (Class A Foam)”, NFPA 298 “Fire Fighting Foam Chemicals for Class A Fuels in Rural, Suburban, and Vegetated

Areas”, or NFPA 1150 “Foam Chemicals for Fires in Class A Fuels”.

4.3 FOAM COMPATIBILITY

CAUTION

Do not mix different types of foam concentrates or foams of the same type from different manufacturers. Mixing of foam concentrates can cause the contents of the foam tank to gel and produce unpredictable results. Clean tank and foam passages thoroughly when changing foam types.

Medium Expansion Nozzle — produces the greatest expansion ratios. It should be used on Class B fuels for vapor suppression and

Class A fuels when a longer lasting insulating layer of drier foam is desired.

Low Expansion Nozzle — can be used with either Class A or B foam solutions. Reach is slightly less than the smooth bore. It should be used on Class B fi res for extinguishment and Class A fuels to soak the fuel with a wet foam solution.

Straight Stream Nozzle — is for Class A foam solutions. Foam expansion will be negligible. It should be used where maximum reach or penetration is desired.

The Class B foam used for calibration is the “Universal Gold 1%/3% Alcohol Resistant Aqueous Film Forming Foam (AR-AFFF)” from

National Foam. The calibration viscosity is 2500 centipoise tested with Brookfi eld #4 Spindle @ 60 rpm

The calibration hose length is 50ft.

5.0 MAXIMUM HOSE LAY

The maximum hose lay is based on the back pressure. Pushing the foam solution through the hose and eductor causes back pressure on the eductor exit. If the back pressure on a 200 psi (14 bar) nozzle is over 130 psi (9 bar) the eductor will not work. If the back pressure on the 150 psi (10 bar) eductor is over 80 psi (5.5 bar), the eductor will not work.

Elevation loss adds to the back pressure when the nozzle is higher than the eductor. For each foot in vertical height, there is 0.4 psi elevation loss.

WARNING

Do not exceed the maxmum back pressure. Excess back pressure causes loss of foam fl ow resulting in risk of injury or death from an ineffective stream. Verify that adequate foam fl ow is established and maintained.

The eductor can be used with or without a monitor. The maximum hose lays and elevations change due to the different friction losses in the monitors. Please use the appropriate chart for the inlet pressure and the appropriate portable monitor if one is used.

To use in a permanent installation with another monitor, calculate friction loss in pipes and elevation changes to fi nd correct setup.

To calculate back pressure, add the nozzle pressure, hose friction loss, and elevation pressure loss together, and make sure the sum does not exceed 130 psi (9 bar)or 80 psi (5.5 bar) depending on the model. The Go/No-Go pressure gage on the outlet of the unit indicates acceptable back pressure levels. Should the gage show a pressure in the No-Go (red) range, shut down the line and change the line setup to lower the pressure.

NOTE: Low pressure 150psi (10 bar) eductors are only compatible with 55 psi (4 bar) nozzles.

NOTE: Metric version eductors are only compatible with 4bar nozzles, and do not work with the Partner and Partner-Lite monitors.

Friction loss varies with different brand hoses. Please determine the friction loss of your own hose. The nominal fl ow of the eductor is the sum of the water plus the foam concentrate when set at 6%. The eductor should always have 200 psi (14 bar) at the inlet unless otherwise specifi ed on the eductor body. The water fl ow does not change with different percentage settings; however the inducted concentrate will change when the percentage setting is changed. Therefore, the total fl ow exiting the eductor is lower at 1/2% than at 6%. Lower fl ow rate reduces nozzle pressure and hose friction loss. Longer hose can be used when proportioning rate is less because less work in needed to move less concentrate.

6.0 NOZZLE SELECTION

Eductors work with any nozzle whose gallonage is equal or larger than eductors’. However, if a larger gallonage nozzle is used, the reach of nozzle and the proportioning rate of the eductor will be compromised.

Fog-type nozzles have the greatest reach in the straight stream position. The fi nished foam is produced as the stream projects forward, and the greatest expansion is at the end of the stream. While straight stream gives maximum reach, it can also splash fl ammable liquids if not carefully applied. The stream impact can be softened by defl ecting the stream off nearby objects. The stream can also be trimmed to a 10-15 degree pattern which gives good reach and creates a softer “snow-fl aking” effect at the end of the stream.

The expansion ratio is the amount of fi nished foam produced compared to the volume of foam concentrate/water solution used to generate the foam. For example: A 10:1 expansion ratio will production 3500 gallons of fi nished foam from a 350 GPM nozzle.

Non-aspirated automatic nozzles can produce expansion ratios of 6-8:1 when measured at the end of the stream. By maintaining a constant nozzle pressure, automatic nozzles keep the velocity of the stream high. Large amounts of air are pulled into the stream and mix with the foam concentrate/water solution as the stream leaves the nozzle.

Air-aspirating devices, such as the TFT FOAMJET, allow a wider selection of foam concentrates to be used, and can produce a better quality of fi nished foam. Air-aspirating attachments will, (1) improve the 1/4 drain time, (2) produce a more uniform bubble structure,

(3) improve the burn back resistance of the fi nished foam, and (4) the foam blanket is visibly thicker. This thicker foam blanket has better vapor suppression and is longer lasting than foam from non-aspirated nozzles. The fi nal expansion ratio and, therefore, the amount of fi nished foam, depends on the type of foam concentrate being used.

WARNING

The nozzle must be operated fully open to prevent excessive back pressure which will prevent foam pickup. Lack of foam can result in injury or death.

The following table lists the compatibility between eductors and nozzles. NOTE: A nozzle under 100 psi will result in lower nozzle

pressure and shorter stream reach.

9.1 FOAM SUPPLY LOGISTICS

When using Class B foams for extinguishing burning pools of liquids a continuous foam supply is essential. Foam fl ow may be interrupted by not changing foam buckets quickly or by switching the metering head to OFF. Foam buckets can be diffi cult to move or open quickly, therefore training and planning for a continuous foam supply is recommended.

DANGER

Lack of foam can place operator at risk of injury or death. Establish foam fl ow before advancing into hazardous situations. Make sure you do not run out of foam concentrate before the task is complete. Check concentrate level periodically and keep an adequate supply on hand.

10.0 MAINTENANCE

The eductor does not need regular maintenance. However, make sure the eductor is completely cleaned after each use. Otherwise the foam concentrate may dry inside and around the percentage ball resulting in plugged metering orifi ces. Look down inside the metering head after fl ushing and check valve to ensure clean passageways.
