6-6 PRECAUTIONS FOR GROUP CON-
TROL SYSTEM OR TWO REMOTE CON-
TROLLER CONTROL SYSTEM
This system provides two other control systems
beside individual control (one remote controller con-
trols one indoor unit) system. Confirm about your sys-
tem to Daikin dealer.
• 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-
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.
• Adjust the air outlet properly and avoid direct air
flow to room inhabitants.
• Adjust the room temperature properly for a com-
fortable environment. Avoid excessive heating or
cooling.
• Prevent direct sunlight from entering a room dur-
ing cooling operation by using curtains or blinds.
• Ventilate often.
Extended use requires special attention to venti-
lation.
• 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.
• 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 “ ” (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.
• Do not use other heating devices directly beneath
the indoor unit.
If you do, they might get deformed by the heat.
• Fully use the function of air flow direction adjust.
Cold air gathers on the floor, and warm air gathers
in the ceiling.
Set the air flow 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.
