Section 1: Sacksafoam II Overview
Introduction to Model 8044
This manual provides helicopter operators with important information on the operation and maintenance of
the Sacksafoam dispensing system for use with the Bambi bucket.
The Sacksafoam II has advanced features to enhance the efficiency of helicopter fire fighting.
The control box has a quartz digital timer to control the delivery of an accurate percentage of foam concen-
trate. The timer circuit has crowbar over-voltage protection and its own circuit breaker.
The operation of the Sacksafoam II can be quickly mastered by users with no prior experience. Several
dumps with foam will provide familiarity with the use of the system.
Please read this manual prior to flying the bucket, particularly the sections on installation, filling and dis-
pensing. If problems are experienced, please refer to the manual.
For your own protection and for longer system life, always heed the instructions and warnings. Ignoring
them could result in damage to the Sacksafoam II, the Bambi bucket and aircraft or in personal injury.
SEI offers complete parts supply and repair facilities for the Sacksafoam II. For maintenance and repair pur-
poses, parts diagrams and descriptions are provided in this manual.
When ordering parts, please provide the model and serial number of the unit which is printed on the back of
the controller and on the inside of the container lid that is normally removed during operation. The side of
the grey container also shows the Sacksafoam model number.
Additional copies of this manual are available from SEI Industries Ltd.

Section 1: Sacksafoam II Overview System Description
Sacksafoam II Model 8044 Operations Manual (Version C) 2
System Description
The Sacksafoam II Model SF2-8044 is used inside smaller helicopters to supply foam to the Bambi
bucket (models 8096 to 1821).
Sacksafoam II model SF2-8044 will hold up to 10 USG (38 litres) of foam concentrate. The foam is held
in two standard 5 USG (19 litre) containers within a large plastic case. The unit is self-contained and de-
signed to prevent foam from contacting the helicopter.
The Sacksafoam pump is operated by a controller box with a long wiring harness. A timer on the controller
box determines the amount of foam concentrate that is pumped into the Bambi bucket. This controller box
comes in two models; an in-dash mount and a remote mounted model.
Ground crew members should replace the foam containers as required. In areas, where a second member is
allowed on board, replacement of the container can be accomplished in flight. This same procedure applies
to foam dispensing. Either the pilot or a crew member can activate the foam dispenser.
Unpacking
Whether receiving the Sacksafoam II for the first time or unpacking it at the start of the season, ensure that
you have the following:
1. Sacksafoam II unit
2. Controller box with cable
3. 6 ft. (1.8 m.) breakaway hose
4. 1 male/1 female garden hose fitting
5. Webbing tie-down straps (two), attached to the grey container.
The following operator-supplied equipment is also required:
1. Dump hose to supply foam to the Bambi bucket (5/8" hose with a 5/8" female garden hose fitting
on one end).
Important Note
Cable and hose lengths must be determined by the operator. They will depend on the helicopter
model, Bambi bucket model and length of the cargo line/longline in use. Please refer to the Bambi
bucket operations manual.

The control box has a 3-amp breaker that protects its electronic components. Be sure to observe the correct
polarity. The control box will not operate if hooked up with reverse polarity.
The injection pump is protected by the helicopter circuit breaker. The injection pump will work, but at a
greatly reduced volume, if hooked up with reverse polarity.
1. Connect power input wires (red is positive, black is negative) to a 28-volt direct current power
supply, protected by a 10-amp breaker (20-amp breaker for HL series Sacksafoam only). In this
case, 28-volts is the nominal charging voltage on a 24-volt system.
2. Depending on the model, mount the control box in the appropriate location (the standard model
can be mounted in a convenient location, the console model must be mounted on the console).
3. Connect the nine-pin plug to the socket on the back of the control box (pin 1 is positive, pin 2 is
negative).
4. Place the Sacksafoam unit inside the helicopter and remove the lid. Ensure that the lid is stored
securely or removed completely from the helicopter.

Important Note
Make sure the circuit can carry a load of 11-amps at 24VDC.
Caution
Excessive force or twisting on the wiring connector can damage the contacts.

5. Secure the "D" rings to the cargo tie-downs on the
floor of the helicopter. Tie the supplied webbing
straps onto the Sacksafoam cleats.
6. Attach power to the unit.
7. Uncoil the stored breakaway hose and connect the
breakaway hose to the foam outlet fitting.
8. Push the garden hose fitting into the free end of the
breakaway hose.
Secure using cleats and "D" rings.
Pushing in fittings.

9. Secure the breakaway hose to the helicopter. Run the 5/8" (16 mm) ID female garden hose from
the end of the breakaway hose down to the Bambi bucket. Attach the hose to the suspension lines
using tie wraps. Take care not to pinch or kink the hose as this will restrict the flow of foam.
Warning
Do not secure the garden hose fitting to the breakaway hose with a clamp. The breakaway hose is
intended for safe jettisoning of the Bambi bucket.
Important Note
If the bucket has to be jettisoned, the hose will pull apart at the unclamped fitting. Since the break-
away hose is secured, there will be no tendency for the garden hose to pull the Sacksafoam from
the helicopter. In this event, any foam in the hose will drip safely outside the helicopter.

Testing the Sacksafoam
Dry Test
Important Note
The testing procedure should be performed before every use to check the operation of the Sasksa-
foam unit.
Important Note
A dry test can be done to determine if all power hook-ups are correct. Set the controller to 10 sec-
onds, take one dip tube out and lift the float on the end of the dip tube. If the pump starts, the hook-
up is correct.
