Furnace Control
Use this screen to control the power to the furnace and turn the Furnace ON or OFF. The
Furnace begins to cool down when it is turned Off. It can take a long time to fully cool to
room temperature, at least eight hours. Whenever the Analyzer is powered on, the
Furnace is automatically powered on by default.
• Furnace Cooling Guidance: Turn the Furnace OFF and open the Analyzer door.
Allow the Analyzer to remain On so the Carrier Gas continues to flow into the
Furnace, thus cooling it down faster.
Important! Turning O
FF the Furnace Power also disables the power to the Furnace
Temperature Sensor, which gives real-time temperature readings of the electric Furnace.
To check the Furnace Temperature after turning the Furnace Power Off, follow this
procedure, “To check the Furnace Temperature while the Furnace is Off” on page 147
.
Figure 4-40: Menu → Service → Furnace Control
