the 1HR. TIMER button.

a pointed object such as the tip of a pen. After 5
seconds, release the ACL button first.

TIMER buttons.

operation button of the remote controller. (Fig. 9)
This starts the fan producing uncooled forced air
with the 3 indicator lamps (OPERATION lamp,
TIMER lamp, and HIGH POWER lamp) on the
main unit blinking. (Fig. 11)
After 3 minutes, the system shifts into cooling
operation, and cool air will start to be felt. Cooling
mode test run is unaffected by the room tempera-
ture.

controller again to stop the test run. (Fig. 9)

controller to release it from Test Run mode to return
to normal mode. (Fig. 9)
" " and "oP-1" will disappear from the remote
controller clock display area.

Troubleshooting:
In the event that the green OPERATION lamp is blink-
ing upon powering up the system, an error condition
exists. In this case, refer to the self-diagnostics proce-
dure which can be seen by opening the air-intake grille.
IMPORTANT
After the test run is completed, be sure to press the
ACL (Reset) button to return to normal mode. The air
conditioner will not operate correctly if this is not done.
