NOTE: When using a POC or PSS injector with the subambient accessory, the injector
temperature must not be set below the oven temperature. You can minimize coolant
consumption if using the oven subambient with the PSS or POC installed but not being
used, by deconfiguring the PSS or POC.
Setting a Coolant Cut-In Temperature
The coolant cut-in temperature is the temperature at which the coolant starts to cool the
oven. The default cut-in temperature is 60 ° C. The allowable cut-in temperature range is
30
°
C - 110
°
C. We recommend that YOU NOTE THE AMBIENT TEMPERARTURE
AND SET
the cut-in temperature 20 °C above your current ambient temperature.
For example: A room temperature of 20 ° C uses a default temperature of 40 ° C, whereas
a room temperature of 25 ° C uses a 45 ° C cut-in temperature. Examples for setting up
isothermal, 1, and 2 ramp programs follow.
NOTE: Higher cut-in temperatures cause more coolant to be consumed.
Setting Up an Isothermal Program
Setting up an isothermal program requires entering the following information in the
sequence shown:
• Initial oven temperature (Temp 1)
• The total run time for the initial temperature (Time 1)
• A temperature rate increase of 0 (Rate 1).
