invalidate the warranty. Before proceeding with replacement
ensure the unit is in a clean, dust and humidity free area.
Remove the four screws from the base plate, two at the front, one
at the far right hand side in front of the detector PCB the other on
the far left hand side. Carefully lift the monochromator assembly
unplugging the connectors SK1 and SK9 without straining the
cables. The monochromator can now be removed.
Replacement is the reverse of dismantling, but ensure that all
cables are carefully fitted in the appropriate recesses so that they
are not crushed when screwing the unit down. When fitting a
replacement unit ensure a full calibration is run so that the new
calibration data for the new monochromator is stored. (See Section
8.5, 8.4 and 8.7)
Power Supply PCB
With the monochromator removed as above
the power supply PCB is easily removed by undoing the four
screws holding it to the lower case assembly. SK3 to the
transformer and SK1 to the fan should be removed before lifting it
out of the lower case.
Cooling Fan
Carry out the above procedures to enable the fan to
be lifted out of its recess in the lower case. Ensure the position of
the retaining spring and the direction of the airflow are noted for
re-assembly.
Transformer
Remove SK3 from the power supply PCB and the
push on connectors for the cables that go to the mains switch and
inlet filter assembly. Then remove the transformer by undoing the
single bolt through the centre that holds it to the moulded bracket
in the base assembly.
