CHECKING YOUR HUMIDIFIER OPERATION
After winter startup or servicing, check the humidifier operation:
1. Turn on the humidifier power and water supply.
2. Turn H8908B Control to highest setting, or H1008A Control to test position; set
thermostat to 10°F (6°C) above room temperature.
NOTE: The H1008A Automatic Humidity Control stays in test mode for thirty minutes.
Then it automatically resets to the maximum frost factor setting. If system
checkout is not completed in thirty minutes, test mode can be extended by
turning dial setting back and then returning it to test mode.
3. Observe that water is flowing out of the drain hose.
NOTE: The furnace blower must be on to activate the humidifier.
4. Reset thermostat and H8908A Control to comfortable setting or H1008A
Automatic Control to desired frost factor setting for automatic operation.
