Step 10. Airflow Configuration Setting
When the Air Outlet Selection Switch (found behind the
filter cover, see illustration) is set in the left position, the
airflow outlet is determined by the mode of operation
(heating or cooling). This is the factory default setting.
When the Air Outlet Selection Switch set in the right
position, airflow will be supplied only out of the upper
outlet. This setting must be made manually.
