Notes:
• The power indicator light will start and stop with the heater.
• For units installed in a small shelter or prefabricated structure, it is recommended that the steam
vent is pointed to the outer side of the structure.
The heater temperature is factory-programmed at 108 °C (226 °F) at the factory and the sample flow
rate must be between 100 and 150 ml/minute (6 and 9 L/hr). Decrease the flow rate if there is no
vapor at the steam vent. Droplets of hot boiling water at the steam vent shows that the distilled water
is too hot. If the distilled water becomes too hot, decrease the set temperature or increase the flow
rate within the specified range.
Refer to Figure 9 on page 16.
1. Set the water flow to the cooler to on.
2. Examine cooler for leaks at the two cooler inlets and the outlet.
3. Examine the outlet tube for correct drainage.
4. Set the sample flow to on.
5. Adjust the sample flow to 100 to 150 ml/minute.
6. Look for leaks and for correct drainage.
7. Set the temperature controller power switch to on. Refer to Figure 8. The power light comes on.
8. Make sure that the display on the controller is on.
9. Monitor the temperature controller. The temperature will increase continuously to approximately
106 °C.
Note: The temperature controller may not reach 106 °C, based on local air pressure and
temperature. The heater will heat the sample to the boiling point of water. If there is a constant
column of water vapor from the steam vent, the unit is operating correctly.
