Replacing The Filter; Charging The Batteries - CORNING Stripettor Ultra Manual De Instrucciones

7. Replacing the filter

CAUTION:
The work safety instructions given in section 2 shall be observed when disassembling
the pipet controller.
The filter replacement is necessary, if drawing efficiency deterioration is observed.
The direct reason may be a dirty filter after a long period of use.
In order to replace the filter:
• Remove the pipet.
• Unscrew the nose piece (Figure 4A).
• Remove the membrane filter (Figure 4A) and the pipet holder (Figure 4B).
• Rinse the holder using a wash bottle (Figure 4C).
• Blow liquid out of the holder and set it aside until it is completely dry.
• Install new membrane filter (Figure 4D) and assemble the device in reverse order.

8. Charging the batteries

CAUTION!
The pipet controller may be charged only with the original charger. The main voltage must
conform with the specification on the charger.
Using chargers other than the original one may damage the battery.
The pipet controller is delivered with 3 NiMH type AAA batteries.
The batteries can be replaced easily if necessary after the battery cover is taken off
(Figure 1K). The manner in which the batteries are arranged is shown in Figure 8.
Charging:
1. Charging temperature: 10°C to 35°C.
2. Charging the battery is carried out through a charger (power supply) by direct connection
to the main power. Batteries charging is indicated by successive lighting of "bars".
3. Full charging time: 7 to 8 hours.
4. The batteries are charged when all 3 "bars" are displayed simultaneously
(Figure 5.1).
When the batteries are charged, the charging circuit disconnects automatically.
The service life of the batteries: approx. 1,000 charging cycles, if used correctly.
It is not possible to overcharge the batteries if all instructions of the manufacturer
are followed.
