Peltier temperature -90°C

Hi, We have a Agilent 5110 ICP-OES and when we started up the instrument, several times the temperature of polychromator´s peltier reach -90°C. In the technical consult the engineer say that the problem could be moisture in the argon Supply line that condense on the optic chamber and purging with boost for 3-4 hours may be solve the problem but not always work.
