2.1.3 Location
Position the instruments in the laboratory at a location convenient for
operation, free from vibrations and protected against a corrosive at-
mosphere and contamination by chemicals. The same applies to all
other components of the IC system.
To avoid disturbing temperature influences on the insulated column
compartment, the entire system including pump and eluent reservoir
must be protected against direct sunlight.
2.1.4 Arrangement of the instruments
If the 817 Bioscan is used as a single detector (see chapter 2.4), the
709 IC Pump, 812 Valve Unit and 817 Bioscan are best stacked on top
of one another in this order.
In a two-channel system (see chapter 2.5), the optimum arrangement
(1, 2 or 3 towers) depends on the laboratory space available.
In general, the IC pumps should be set up at the very bottom and the
IC detectors at the very top.
2.2 Mains connection
Follow the instructions below for connecting to the power supply. If
the instrument is operated with a mains voltage set wrongly and/or
wrong mains fuse, there is a danger of fire!
2.2.1 Setting the mains voltage
Before switching on the 817 Bioscan for the first time, check that the
mains voltage set on the instrument (see Fig. 4) matches the local
mains voltage. If this is not the case, you must reset the mains voltage
on the instrument as follows:
1 Disconnect mains cable
Disconnect mains cable from mains connection plug 17.
2 Remove fuse holder
Using a screwdriver, loosen fuse holder 16 below the mains
connection plug and take out completely.
3 Check and change fuse if necessary
Carefully take the fuses installed for the desired mains voltage
out of fuse holder and check their specifications:
