6-6 PRECAUTIONS FOR GROUP CON-

This system provides two other control systems
beside individual control (one remote controller con-
trols one indoor unit) system. Confirm the following if
your unit is of the following control system type.
• Group control system
One remote controller controls up to 16 indoor
units. All indoor units are equally set.
• Two remote controller control system
Two remote controllers control one indoor unit (in
case of group control system, one group of indoor
units). The unit is individually operated.
NOTE
• Contact your Daikin dealer in case of chang-

systems.

8. FOLLOWING SYMPTOMS ARE
8-1 THE SYSTEM DOES NOT OPERATE
• Ventilate often.
Extended use requires special attention to venti-
lation.
• Keep doors and windows closed. If the doors and
windows remain open, air will flow out of your
room causing a decrease in the cooling or heating
effect.
• Never place objects near the air inlet or the air
outlet of the unit. It may cause deterioration in the
effect or stop the operation.
• Turn off the main power supply switch to the unit
when the unit is not used for longer periods of
time. If the switch is on, it uses electricity. Before
restarting the unit, turn on the main power supply
switch 6 hours before operation to ensure smooth
running. (Refer to the chapter "Maintenance" in
the indoor unit manual.)
• When the display shows "
air filter), ask a qualified service person to clean
the filters. (Refer to the chapter "Maintenance" in
the indoor unit manual.)
• Keep the indoor unit and remote control at least
1 m away from televisions, radios, stereos, and
other similar equipment.
Failing to do so may cause static or distorted pic-
tures.
NOT AIR CONDITIONER TROU-
BLES
• The air conditioner does not start immediately
after the ON/OFF button on the remote con-
troller is pushed.
If the operation lamp lights, the system is in nor-
mal 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 pre-
pared for operation.
