tions
The equipment is designed to be safe under the
following conditions:
• Indoor use
• Altitude up to 2000 m.
• Temperature 5 °C to 40 °C.
• Maximum relative humidity 80 % for tem-
peratures up to 31 °C decreasing linearly to
50 % relative humidity at 40 °C.

8.2 Installation
8.2.1 Voltage Feed
Mains Voltage Selector
A mains voltage selector is located at the rear of
the Sampler and is used for setting the correct

mains voltage. The mains voltage selector has the
following positions: Neutral, 100V, 115V, 130V,
200V and 230V. Refer to the figure.
When the Sampler is delivered, the selector is in
the neutral position and there are no fuses fitted.
Note:
Never connect the Sampler to the
mains before setting the mains volt-
age selector into the desired position
and fitting the fuses.
Fuses
Choose the appropriate fuse in accordance with
the following table:
Mains voltage Fuse
100-130 V T 0.5 A
200-230 V T 0.315 A
Fit the fuses as shown in the figure.
Fig. 8:1 How to fit the fuses
8.2.2 Connecting the Sample
Probe
Fit the sample probe by pushing it down into the
probe arm. The probe may protrude downwards a
maximum of 125 mm.
Fix the probe by tightening the screw on the arm.
For some analysis system different sample probes
are used. These are supplied in accessory kits and
are described in respective analysis system´s User
Manual or separate Operator Instructions
supplied with the kits.
When the sample probe is fitted, check that the
probe arm has slotted into its groove by carefully
turning it both to the left and to the right. You
should hear a clicking sound to indicate that the
arm is in the right position.
For FIAstar systems the Random Access kit needs
to be installed, see the enclosed Operators
instruction for mounting instructions.
8.2.3 Fitting the sample rack
Fit the sample racks so that the coding on the
racks and the centre circle on the sampler match
each other.
The sample racks must be positioned correctly to
ensure that the numbering of the sample cups will
