8. Ensure the cover is fully open and retained by the stay.
9. Perform the necessary maintenance inside the instrument.
Figure 45 illustrates the primary component parts of a Frontier IR Dual-Range
spectrometer.
Figure 45 Frontier IR FT-IR/NIR components
NOTE: The Frontier FT-IR/FT-FIR spectrometer has one source only, in the MIR source
position. The FIR detector is in the NIR detector position.
NOTE: If you have an MCT detector fitted for the MIR range, the MCT detector is fitted
toward the rear of the instrument and the NIR/FIR detector is fitted at the front of
the instrument.
10. Close the cover.
11. Lock the two locking bolts by inserting the wrench into each bolt in turn and rotating it
opposite to the direction indicated by the arrows in Figure 44.
12. If required, reinstall the sampling accessory by sliding it on the ledge and pushing it into
the sample compartment until it engages with the connector.

the cover downwards until the clip engages.
14. Reconnect the power cable and switch the power back on.
15. If required change the desiccant (see
Changing the Desiccant
on page 65), and/or
purge the instrument (see
Purging the
Spectrometer on page 70).
If the cover is left open for more than 1 hour, the desiccant should be replaced.
