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 batter y
before storage.
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 our authorised distributors to ensure that the
LSU operates satisfactorily.
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.
