environment. Avoid excessive heating or cooling.
Prevent direct sunlight from entering a room during cooling
operation by using curtains or blinds.

OLLOWING SYMPTOMS ARE NOT AIR
CONDITIONER TROUBLES
Symptom 1: The system does not operate
The air conditioner does not start immediately after the ON/OFF
button on the remote controller is pushed.
If the operation lamp lights, the system is in normal condition.
To prevent overloading of the compressor motor, the air
conditioner starts 5 minutes after it is turned ON again in case it
was turned OFF just before. The same starting delay occurs
after the operation mode selector button was used.
If "Centralized Control" is displayed on the remote control and
pressing the operation button causes the display to blink for a
few seconds.
This indicates that the central device is controlling the unit.
The blinking display indicates that the remote control cannot be
used.
The system does not start immediately after the power supply is
turned on.
Wait one minute until the micro computer is prepared for
operation.
Symptom 2: Cool/Heat cannot be changed over
When
