•This starts the fan producing uncooled forced air with the 4 indicator lamps (OPERATION lamp, TIMER lamp, QUIET lamp, and ION lamp) on the main unit blinking. (Fig. 59c)

•After 3 minutes, the system shifts into cooling opera- tion, and cool air will start to be felt. Cool mode test run is unaffected by the room temperature.

(3)Press the ON/OFF operation button of the remote con- troller again to stop the test run. (Fig. 59a)

•“ ” and “oP-1” will disappear from the remote con- troller display area.

In the event that the green “Operation Light” is blinking upon powering up the system, an error condition exists. In this case, refer to the self-diagnostics procedure on the

inside of the front cover.
