Cat. No. 78002001
Read this User Guide carefully, and become thoroughly familiar with
the operation and maintenance of the Laerdal Suction Unit (LSU) before using it.
The LSU should only be used by persons trained in the use of medical
suction equipment.
The LSU is not suitable for use in the presence of flammable liquids or gases.
There can be a danger of explosion or fire.
The LSU is not intended to be used in MRI enviriments.
Do not re-use the canister or patient tubing. Re-use will lead to
increased risk of cross-contamination, degradation of performance and/or
device malfunction. Laerdal is not responsible for any consequences of re-use.
Do not use the LSU under environmental conditions that are outside the
ranges specified under section 9.6. This can endanger safety and adversely
affect operation of the device.
Even if the Operating Knob is in “0” position, voltage is present on some
of the internal circuitry, when the LSU is connected to mains. To fully
remove power, pull out the Power Cord.
Battery:
- The LSU must be charged between each clinical use
- To maintain satisfactory operation of the battery, it is recommended to place
the LSU on continuous charge when not in use.
- The LSU must be placed on charge for a minimum of 4 hours to reach full battery
capacity. The fast charging gives approx. 80% battery capacity after 3 hours (for a
new battery). Please note that repetitive 3 hour charging is not recommended.
- If it is not possible to place the LSU on continuous charge when not in use, make
sure the battery is charged for a minimum of 4 hours at least once a month. If LSU
battery is kept on constant charge, perform device test at least once a month to
exercise battery.
- Do not store the battery when it is discharged. Always fully charge the
battery before storage.
Do not block the Exhaust Outlet during use. This will lead to reduced flow and
can also cause damage to the LSU.
If overflow of liquid from the Canister into the pump is suspected, discontinue use of
the LSU and contact a Laerdal Service Center.
Disconnect the LSU from external power prior to cleaning. Use a minimum of
liquid to prevent any electrical shock hazard.
Do not immerse the LSU or allow it to stand in water or other liquids. This might
damage the device, and cause electrical hazard.
Do not pump any cleaning solution or other liquids through the vacuum pump,
i.e. through the Vacuum Connector. This can damage the LSU.
Use only accessories supplied by Laerdal or one of its authorized dealers to
help ensure that the LSU operates satisfactorily.
Caution: Federal (US) law restricts this device to sale by or on the
order of a physician.

2.1 Indications for Use
The LSU is a portable, electrically powered, medical suction equipment
intended for field and transport use. It is intended for intermittent
operation to remove secretions, blood or vomit from a patient´s airway
to allow ventilation. Higher vacuum levels are generally selected for
oropharyngeal suctioning, and lower vacuum levels are usually selected
for tracheal suctioning and the suctioning of children and infants.
2.2 Contraindications
None known.
2.3 Features and Benefits
- Splash proof, rugged and solid.
- Easy access to the tubing.
- Equipped with an internal battery that can easily be replaced
without using tools.
- Charging of battery can be done directly from AC or DC mains -
no external charger is needed.
- Fast charge of 3 hours, giving approx. 80% battery capacity.
- Operation possible from internal battery and directly from AC or DC mains
- no adapter is needed.
- A large combined ON/OFF switch and vacuum selector makes operation
easy even with heavy-duty gloves.
- A green LED bar graph makes it easy to observe the actual vacuum level
during operation.
- Another green LED bar graph indicates approx. remaining battery capacity.

2.4 Limited Warranty
The LSU comes with five (5) year limited warranty*. See the enclosed
“Laerdal Global Warranty” for terms and conditions.
The warranty is also available at www.laerdal.com
* Excluding the canister, tubing systems and battery.
2.5 Unpacking
- Remove the LSU from its packaging and inspect all parts for
damage. If there are any signs of damage or if any parts are missing, imme-
diately notify Laerdal or one of its authorized dealers.
- Insert the battery according to section 5.6.
- Place the LSU on charge for a minimum of 4 hours to make sure you have
a fully charged battery (see section 5.4).
- Perform the Device Test according to section 3.2.3.

3.2 User Interface
3.2.1 Operating Knob
The Operating Knob is a combined ON/OFF switch and vacuum selector,
located at the bottom of the User Interface.
The LSU is switched ON by turning the Operating
Knob to the required setting. Each setting
indicates the maximum achievable vacuum level
for the selected position (80, 120, 200, 350,
500+ mmHg). The free air flow value changes
along with the increasing vacuum settings
(see section 9.4 for details). The LSU is switched
OFF by resetting the Operating Knob to “0”.

3.2.2 Indicators
3.2.2.1 Power ON Indicator
This green LED has 3 modes:
- It is lit continuously while the LSU is switched ON.
- It flashes rapidly (approx. twice per second) during the Device Test.
- It flashes slowly (approx. once per second) while the Automatic
Power-save Function is activated, if the Device Test is interrupted
and when the battery is discharged.
3.2.2.2 External Power Indicator
This green LED is continuously lit while external AC- or DC-power is
connected.
3.2.2.3 Failure Mode Indicator
The red LED is lit when a possible malfunction of the LSU has been
detected. If lit turn the LSU OFF, and then ON again to check if the
indication disappears*. Provided that the indication does not occur
again the LSU can be operated. If the Indicator continues to be lit after
three OFF/ON cycles and after replacing the battery with a fully charged
battery, discontinue use and contact a Laerdal Service Center. (See section 6).
*Failure Mode Indication caused by external electrical interference may occur on any digital
equipment including the LSU. Such fault will usually not be repeated.
3.2.2.4 Vacuum Indicator
This green LED bar graph displays the actual
vacuum level during operation of the LSU. Each fully lit
segment represents 50 mmHg. If a segment has a weak
light, this represents 25 mmHg (e.g. 125 mmHg means
2 fully lit and 1 weakly lit segments).
3.2.2.5 Battery Status Indicator
During operation from internal battery and during charging
the displayed values must only be used as indications.
Several parameters can influence battery capacity e.g. device settings,
state of battery, temperature etc.

mmHg 80 120 200 350 500

This green LED bar graph has 3 functions:
During operation from internal battery - indicates approx. remaining battery capacity.
Note: Immediately after turning the LSU ON and immediately after switching from external
power to internal battery operation, all 4 LED’s will flash for 5 seconds before the remaining
battery capacity is displayed. Due to the nature of voltage based battery capacity measurement,
the battery status indication may differ from unit to unit. Each battery may vary in voltage versus
remaining capacity, thus allowing for variability in the reading. Other outside variables such as
temperature may also affect accuracy. The indication is targeted to show battery capacity as
indicated below. The graph shows how the accuracy of the indication can vary.
TYPICAL REMAINING BATTERY CAPACITY
(for a new battery stored in room temperature ) OUTPUT
> 50% 4 LEDs lit.
30 - 50% 3 LEDs lit.
20 - 30% 2 LEDs lit.
< 20% 1 LED lit.
Battery Low; (min. 1 minute of operation left based on
500+ mmHg/free flow). 1 LED flashes.
Note: If the LSU or the NiMH battery has been stored at low temperatures
(< 12 °C / < 54 °F), the LSU may indicate lower remaining battery capacity than actual when
first switched on. This is due to the nature of NiMH batteries. The battery indicator may
flash on one LED, which normally indicates Battery Low. The LED may continue to flash
until the LSU temperature is above 12 °C / 54 °F and the LSU is switched off and on again.
The low battery indication in this instance is not a correct indication of the residual
battery capacity.
During charging - indicates approx. achieved battery capacity.
CAPACITY OUTPUT*
< 75% The LED’s will be lit sequentially.
75-80% 3 LED’s lit and 4th flashing.
> 80% 4 LED’s lit.
*Note: If no battery is installed, the battery status indicator will be fully lit for approx. 5 sec.
until it is automatically turned off.
During the Device Test - indicates which step of the test is currently in
progress or which corresponding test result is being displayed:
LED 1 (lower LED) lit = STEP 1, LED 2 lit = STEP 2 etc.
