1 Cautions and Warnings
Read these Directions for Use carefully, and
become thoroughly familiar with the operation
and maintenance of the 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.
Do not use the LSU under environmental
conditions that are outside the ranges specified
under section 11.6.This can endanger safety and
adversely affect operation of the device.
Battery:
- 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 24 hours to reach full battery
capacity.The fast charging gives approximately
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
24 hours at least once a month.
- 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.
Do not use the Reusable version without a filter
or the Float Ball. Use only the disposable Abbott
liner with filter.
If overflow of liquid from the Canister into the
pump is suspected, the LSU must be returned for
service (see section 9). Overflow of suctioned
material can damage the device.
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 liq-
uids through the vacuum pump, i.e. through the
Vacuum Connector.This can damage the LSU.
Use only accessories supplied by Laerdal or one
of our authorised distributors to ensure that the
LSU operates satisfactorily.

6.5 Charge the Battery
The internal rechargeable Lead-Acid battery can
be charged directly from external AC or DC
power as described in section 3.4. No external
charger is needed.To charge the battery, proceed
as follows:
1. Make sure the Operating Knob is set to "0".
Connect either external AC or DC power to
the LSU and charging will start automatically.
2. During charging the Battery Status Indicator
will indicate approx. achieved battery capacity
(see section 3.2.2.5 for details).
3. The LSU must be placed on charge for a
minimum of 24 hours to reach full battery
capacity.The fast charging gives approx.
80% capacity after 3 hours
(for a new battery).
Repetitive charging for only 3 hours is
not recommended.
Note:
- To maintain satisfactory operation of the battery,
it is recommended to place the LSU on
continuous charge immediately after use.
- It is recommended to always fully charge the
battery. Repetitive charging to a lower capacity
level will reduce battery life.
- 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
24 hours at least once a month.
- Do not store the battery when it is discharged.
Always fully charge the battery before storage.
- The recommended ambient temperature for
charging is from 15°C to 25°C.
- The battery will not be charged when the LSU
is in operation.
- If no battery is installed, the battery status
indicator will be fully lit for approx. 5 sec. until
it is turned off.
6.5.1 External Battery Charge
The LSU battery can also be charged
in an optional External Battery Charger.
See section 8.
6.6 Check the Battery Quality
If poor battery quality is
suspected, charge the battery
for a minimum of 24 hours and
then perform the following test
without connection to external
power:
- Run the Device Test and then let the LSU
operate continuously at 500+ mmHg setting
and free air flow for 20 minutes.
- If the LSU stops before completing the 20
minutes, the battery should be discarded.

6.7 Replace the Battery
Note:
Use only batteries recommended by Laerdal.
1. Open the Battery Door.
2. To remove the battery, push and move it
slightly to the left and then release.
3. Withdraw the battery from the LSU.*
4. To insert a battery, push it fully in and then
to the right to lock it.
5. Close the Battery Door.
6. After inserting the battery, place the LSU on
charge unless a fully charged battery
is inserted.
*When you discard the battery, dispose of safely in
accordance with local protocols for sealed lead acid
batteries.
6.8 Fastening brackets
The fastening bracket is used to hold the LSU in
the optional wall bracket. Inspect the fastening
brackets for wear and tear regularly.
Replace if worn. See section 8.
6.9 Release arm for Canister holder
An extra release arm for the canister holder can
be attached. See section 8.
7 Device test
The Device test is user initiated test program for
all models which can identify whether the LSU
operates satisfactorily or if the LSU needs
service.
The program runs 4 different tests:
1 It tests for occlusions in the Suction System
(including canister and tubing)
2 It tests the vacuum build-up efficacy of the
Pump System (How much vacuum is built up
within 3 seconds)
3 It tests the maximum achievable vacuum level
of the LSU (reaches this level within
10 seconds)
4 It tests if there are air leakages in the Pump
System (including canister and tubing)
7.1 Setup
Before the test can be performed
make sure that:
- The Patient Suction Tubing is unwound and
not blocked or bent
- The Suction Catheter Adapter is removed
from its holder (if applicable)
- The canister lid,T-bar, angled connector
and tubing are securely fastened.
7.2 Run the Test
1 Press and hold the TEST-Button while setting
the Operating Knob to 500+ mmHg.
Note: Do not release the TEST-Button until min.
2 seconds after the Operating Knob has been set
to 500+ mmHg.The test will start immediately

2 As soon as LED 2 from the bottom of the
Battery Status Indicator comes on (takes
approx. one second), fully block the Patient
Suction Tubing until all 4 LED’s have
illuminated and LED 1 lights up again.*
3 Keep the tubing blocked while LED 2 , 3
and 4 lights up.
4 Release the tubing when LED 1 comes
on again
5 Evaluate the test results (See section 7.3)
6 After evaluating the test results turn the
Operating Knob to "0" to exit the Device Test.
Note:
If you need to interrupt the test and revert to nor-
mal operation, turn the Operating Knob to another
position and then select the required setting.
Note:
To indicate that the LSU is in test mode, the Power
ON Indicator will flash rapidly (approx. twice per
second) until you exit the test program.
* If the tubing is not occluded within 2 minutes, the
test will be interrupted and the Power ON Indicator
will start to flash slowly (approx. once per second).
To restart the test, set the Operating Knop to "0"
and start over again.

* If it is not obvious where the system is leaking; go step by step
through the connections. Start by disconnecting the Vacuum Tube at
the Canister and run the Device Test (blocking the tube). Reconnect
the tube and disconnecting the patient tube, run device test (block
the PATIENT inlet on the Canister). Continue with other connections
until the leakage is identified.
Note: If the LSU does not pass one or more of the
steps in this test after suggested actions are taken,
the device might need to be returned for service
(see section 9).
