Temperature Adjustment
5.1. Steam Heated Systems
Steam control valve is factory set to 180 O F and is normally not field adjustable. This
temperature is adequate for most applications in which sample gas water content is not
in excess of 50% water vapor by volume. Consult factory if condensation in sample
tubing is detected.
5.2. Electrically Heated Systems
1. Check that no condensate is present in sample line between filter and dryer.
2. If water droplets are visible, increase temperature of filter/dryer compartment by
5
°C.
3. Allow about ½ hour for system to stabilize and then check again for condensate.
4. If necessary, continue to increase temperature at 5
°C intervals until condensate
is no longer visible. Do not exceed 100
°C! Maximum system temperature is
100
°C. Operation above this temperature can cause damage to Nafion dryer.
It is essential that purge gas flows continuously and setpoint temperature
is not above 100
°°°°°C to prevent damage to dryer.
