NOTE

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.
