  1. Place humidifier centrally in room, at least 12 inches from walls and furniture.
  2. Set humidistat to desired level (start at 45%).
  3. Choose mist level based on room size and dryness (High for quick humidification).
  4. Monitor room humidity with a separate hygrometer for best accuracy.
  5. Refill tank when low water indicator lights or mist output decreases.
