run down. The unit will start and OPERATION INDICATOR lamp will light.
The first 30 minutes of operation is the test run operation. This operation is for servicing. The Indoor fan speed runs at
High speed and the temperature control does not work.
After 30 minutes of test run operation the system shifts to EMERGENCY COOL/HEAT

ture of 75°F (24°C). The fan speed shifts to Med.

Emergency operation continues until the emergency operation switch is pressed once or twice or the unit receives any
signal from the remote controller. In case of latter normal operation will start.
NOTE
