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-
ing the combination or setting of group con-
trol and two remote controller control
systems.
7. OPTIMUM OPERATION
Observe the following precautions to ensure the
system operates properly.
• Prevent direct sunlight from entering a room dur-
ing cooling operation by using curtains or blinds.
• Do not keep doors and windows opened. If the
doors and windows remain open, air will flow out
of your room causing a decrease in the cooling or
heating effect.
• Do not use other heating devices directly beneath
the indoor unit.
If you do, they might get deformed by the heat.
• 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.
• Adjust the room temperature properly for a com-
fortable environment. Avoid excessive heating or
cooling.
• Ventilate often.
Extended use requires special attention to venti-
lation.
• When the display shows “
” (time to clean the
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.
• 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.)
• Fully use the function of airflow direction adjust.
Cold air gathers on the floor, and warm air gathers
in the ceiling.
Set the airflow direction parallel during cooling or
dry operation, and set it downwards during heat-
ing operation.
Do not let the air blow directly to a person.
• It takes time for the room temperature to reach the
set temperature.
We recommend starting the operation in advance
using timer operation.
8. SEASONAL MAINTENANCE
CAUTION
• Do not touch the air inlets or aluminum fins
of the outdoor or indoor units.
Touching them may result in injury.
• Do not wash the outdoor or indoor units with water.
An electric shock or fire may result.
• Watch your steps at the time of air filter cleaning etc.
If the scaffold is unstable, you may fall or topple
down, thus causing injury.
• Be sure to stop the operation, and turn the
breaker off before cleaning.
This may cause electric shock and injury.
• Consult with the dealer for cleaning the interior
of the indoor units.
Incorrect cleaning may damage the plastic parts
and cause failures, such as water leakage, and an
electric shock may result.
8-1 AT THE BEGINNING OF THE SEASON
Check
• Are the indoor and outdoor unit intake and outlet
vents blocked?
Remove anything that might be blocking them.
Clean the exterior.
• See the operation manual included with the
indoor unit for details on how to clean it.
Turn the power on.
• When the power comes on, the characters in the
remote controller display appear.
(To protect the unit, turn the power on at least 6
hours before operating it. This makes operation
smoother.)
8-2 AT THE END OF THE SEASON
On a clear day, use fan operation for around half a
day to thoroughly dry out the interior of the unit.
• Refer to chapter 6 for details on fan operation.
Turn off the power.
• When the power is shut off, the characters in the
remote controller display disappear.
• When the power is on, the unit consumes up to
several dozen Watts of power.
Turn off the power to conserve energy.
Clean the exterior.
• See the operation manual included with the
indoor unit for details on how to clean it.
