1.0 MEANING OF SAFETY SIGNAL WORDS
A safety related message is identified by a safety alert symbol and a signal word to indicate the level of risk involved with a particular
hazard. Per ANSI standard Z535.6-2006, the definitions 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, may result in minor
or moderate injury.
NOTICE
NOTICE is used to address practices not related to personal injury.
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 fighting fire. 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 flow rate of the mixed water plus
concentrate solution, shall be minus zero (0) percent, plus thirty (30) percent of the manufacturer’s specified 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.

Lack of foam can place operator at risk of injury or death. Establish foam flow 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 fires or Class B foam on Class A fires. Note: Some foam
concentrates are universal and can be used on Class B fires and spills and as a wetting agent
on Class A fires. (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 fire service training to avoid the following:
• Using the wrong type of foam on a fire, i.e. Class A foam on Class B flammable liquid fire
• 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 significant amounts of water or foam.
Such damage may be difficult 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 qualified 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 fire 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 flammable 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-floating
check disk with three fins. The check disk is pressure activated to keep water from coming out of the fire hose and back into the
foam pail.
The metering head contains a red back flush 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 five choices: Off, ½%, 1%, 3%, and 6%. Each foam setting has a precision sized metering orifice in the valve ball.
The eductor cannot be operated between settings, as the metering orifices 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 flow.
5) Adjust the pump pressure so the eductor inlet is set at pressure specified 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 flush button and
run fresh water through the hose and metering head on each setting until there is no visible foam in the flush 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 flush above 75 psi. Rapid back flush discharge from the wand could cause injury.
The back flush 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,
flexible 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 flow, 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 “Specification for Fire Suppressant Foam for
Wildland Firefighting (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 fires 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 Brookfield #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 nozzles 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 flow
resulting in risk of injury or death from an ineffective stream. Verify that adequate foam flow 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 find 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 flow 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 specified on the eductor body. The water flow does not change with different percentage settings; however the inducted
concentrate will change when the percentage setting is changed. Therefore, the total flow exiting the eductor is lower at 1/2% than
at 6%. Lower flow 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 finished 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
flammable liquids if not carefully applied. The stream impact can be softened by deflecting 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-flaking” effect at the end of the
stream.
The expansion ratio is the amount of finished 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 finished 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 finished 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 finished 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 final expansion ratio and, therefore, the
amount of finished 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.

Do not intermix metering heads with eductor bodies of different flow rates. Intermixing can
cause weaker or stronger foam than expected resulting in risk of injury as the ability to control
the fire is compromised.

9.1 FOAM SUPPLY LOGISTICS
When using Class B foams for extinguishing burning pools of liquids a continuous foam supply is essential. Foam flow may be
interrupted by not changing foam buckets quickly or by switching the metering head to OFF. Foam buckets can be difficult to move
or open quickly, therefore training and planning for a continuous foam supply is recommended.
DANGER
©Copyright Task Force Tips, Inc. 2010
Lack of foam can place operator at risk of injury or death. Establish foam flow 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.
15
LIU-360 October 4, 2010 Rev01
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 orifices. Look down inside the
metering head after flushing and check valve to ensure clean passageways.
