6.4.5 Disinfection
To disinfect the parts, the following methods are recommended:
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.
