PerkinElmer Spectrum RX I Getting Started Manual page 25

Before switching on the Spectrum RX I for the first time, renew
the desiccant to make sure that the purge is good. Old used
desiccant releases moisture and can cause catastrophic failure o
CAUTION
the beamsplitter.
Do not use damaged bags of desiccant. Make sure that the bags
o desiccant you use have not been left in contact with the air. f
During the following procedu e, the purged optical system is
exposed to the atmosphere. To minimize the loss of purge, have
the new desiccant ready before you begin, and complete the
CAUTION
procedure as quickly as possible.
Do not start the procedure if the temperature of the Spectrum
RX I has not equilibrated with the ambient temperature of the
laboratory.
Do not start the procedure if the relative humidity is >75%. You
can determine the relative humidity using the humidity detector
on the purge cover (Figure 6).
1. Loosen the screws on the desiccant box, and lift the box from the
Spectrum RX I.
The desiccant box is located behind the sample compartment (Figure 6).
