Emergency operation is available when the remote controller is missing
or has failed, or when the batteries in the remote controller are running
down. The unit will start and OPERATION INDICATOR lamp will light up.
The first 30 minutes of operation is the test run operation. This opera-
tion is for servicing. The indoor fan runs at High speed and the tem-
perature control does not work.
After 30 minutes of test run operation, the system shifts to
EMERGENCY COOL/HEAT MODE with a set temperature of 75°F (24°C).
The fan speed shifts to Medium.
The coil frost prevention works even in the test run or the emergency
operation.
In the test run or emergency operation, the horizontal vane operates in
VANE AUTO ( ) mode.
Emergency operation continues until EMERGENCY OPERATION
switch is pressed once or twice or the unit receives any signal from the
remote controller. In the latter case, normal operation will start.
NOTE:
Do not press EMERGENCY OPERATION switch during normal
operation.
