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 9.6. 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 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 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.
If overflow of liquid from the Canister into the pump is suspected, the LSU
must be returned for service (see section 6). 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 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.

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 (59°F to 77°F ).
- 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.
5.5 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/free flow for 20 minutes.
- If the LSU stops before completing the 20 minutes, the battery
should be discarded.
