9. MALFUNCTIONS NOT RELATED TO HEAT
PUMP
The following symptoms do not indicate heat pump malfunction:
I. THE SYSTEM DOES NOT OPERATE
• The system does not restart immediately after the ON/
OFF button is pressed. If the OPERATION lamp lights,
the system is in normal condition. It does not restart
immediately because a safety device operates to prevent
overload of the system. After 3 minutes, the system will turn
on again automatically.
• The system does not restart immediately when
TEMPERATURE SETTING button is returned to the
former position after pushing the button. If the
OPERATION lamp lights, the system is in normal condition.
It does not restart immediately because a safety device
operates to prevent overload of the system. After 3 minutes,
the system will turn on again automatically.
• The system does not start when the display shows
"CENTRAL CONTROL" and it flashes for few seconds
after pressing an operation button. This is because the
system is under centralized control. Flashes on the display
indicate that the system cannot be controlled by the remote
controller.
• The system does not start immediately after the power
supply is turned on. Wait one minute until the micro
computer is prepared for operation.
II. The fan speed is different from the setting.
• Pressing the fan speed control button does not change
the fan speed.
• When the room temperature reaches the set temperature in
heating mode, the outdoor unit stops and the indoor unit
switches to whisper mode. This is to prevent the cool air
from being blown directly onto anyone in the room.
• To protect electric parts, the unit operates with the airflow
rate at H speed during ELECTRIC HEATER operation
regardless of the remote controller indication.
III. WHITE MIST COMES OUT OF A UNIT
• When humidity is high during cooling operation (In oily
or dusty places) If the inside of an indoor unit is extremely
contaminated, the temperature distribution inside a room
becomes uneven. It is necessary to clean the inside of the
indoor unit. Ask your Daikin dealer for details on cleaning
the unit. This operation requires a qualified service person.
