ket is damaged (fig. 1K).
Connect the charger to charge
the batteries.
Discharged batteries.
Check the valve for flooding.
If it is wet - rinse it and dry.
Check the valve for blockage
or displacement due to excessive
force during pipette installation
- if it is blocked or displaced try
to set it in the right position.
The check valve is blocked
(fig. 1J).
Take the pipette out of the holder.
Disassemble the pipette holder.
Take out the filter - check it for
impurities - if it is dirty, replace it
with a new one.
The filter is dirty (fig. 1H).
The pump is working,
but the pipetting aid does
not draw liquid or draws
liquid very slowly.
If the holder is damaged, replace
it with a new one.
The pipette holder is dam-
aged.
Take the pipette out of the holder.
Disassemble the pipette holder
and check for mechanical
damage.
Clean, wash and dry the pipette
holder.
The pipette holder is dirty
or wet (fig.1G).
The pipette falls out (the
holding force of the pipette
is to small), or tilts to the
side too much.
Action

Problem
17
If the actions specified in the table do not solve the problem, pipetting aid should be sent to
your
Gilson
Distributor.
Warning! Before sending the product should be cleaned and decontaminated.
7 - REPLACING THE FILTER AND CLEANING THE VALVES
Note:
The work safety instructions given in Chapter 2 shall be observed when disassembling
the pipetting aid.
Replace the filter, if the aspiration efficiency deteriorates. This is because the filter may be
dirty after a long period of use.
Note: Only use the original manufacturers filters.
The procedure is shown in (fig. 3).
• Remove the pipette.
• Unscrew the nosepiece (fig. 3A).
• Remove the membrane filter (fig. 3A) and the pipette holder (fig. 3B).
• Rinse the holder with the safety valve using a wash bottle (fig. 3C).
• Blow liquid out of the holder and leave it until it is completely dry.
• Install new membrane filter (fig. 3D) and assemble the device in reverse order.
8 - CHARGING THE BATTERY
The
Gilson Pipetting Aid
has a low battery indicator. If the control lamp (fig. 1E) lights up,
when the aspiration button is pressed, it means that the battery is discharged and should
be charged.
Note:
The Gilson Pipetting Aid may be charged only with the original charger. The mains
voltage must conform with the specification on the charger.
Using other chargers than the original one may damage the battery of the pipetting aid.
Battery charging is regulated by a time circuit, which controls the entire process. When the
battery has been charged, the charging circuit disconnects automatically. This is indicated
by the control lamp (fig. 1E), which shines continuously.
Charging:
1. Charging temperature: 10 °C to 35 °C.
2. Charging is done with the charger included with each pipetting aid.
Battery charging is signalled by the control lamp, which flashes during charging.
3. Full charging time: 11- 14 hours.
Check the pipette holder and the
connector gasket for mechanical
damage - if there is damage,
replace the damaged part with
a new one.
The pipette holder and/or
the connector gasket is
damaged (fig.1G, fig 1K).
