RISK OF FIRE, REPLACE FUSES AS MARKED.
When the voltage selection and fuses are correct for your power source,
plug in the power cable.
The AS 3900 is factory installed with a 250 µl syringe, a 100 µl loop, a
500 µl buffer tubing and a stainless steel sample needle.
A schematic presentation of all parts that have contact with any kind of
fluid is shown below. This sticker can be found on the inside of the front
cover.
To get access to the fluidics, it is necessary to open the front cover of the
AS 3900, therefore remove the screw on the right-hand side of the AS
3900 front cover.
See Table 1 for the dimension of the standard installed tubing.
To obtain an optimal performance of the AS 3900, a correct combination
of syringe, loop and buffer tubing should be installed, see also section
Needle and tubing on page 52.
