OPERATION PROCEDURE

■ If a function that is not available is selected, the
message NOT AVAILABLE will appear.

■ Operating procedure varies with heat pump type and
straight cooling type. Contact your Daikin dealer to
confirm your system type.

■ To protect the unit, turn on the main power switch
6 hours before operation.

■ If the main power supply is turned off during
operation, operation will restart automatically after the
power turns back on again.

NOTE

Precautions for group control system or two remote controller control system

This system provides two other control systems beside individual
control (one remote controller controls one indoor unit) system.
Confirm the following if your unit is of the following control system
type.

■ Group control system

■ Tw o remote controller control system

NOTE

Set the temperature within the ranges mentioned
under "Operation range" on page 2.

One remote controller controls up to 16 indoor units.
All indoor units are equally set.

Tw o remote controllers control one indoor unit (In case of group
control system, one group of indoor units). The unit is
individually operated.

Contact your Daikin dealer in case of changing the
combination or setting of group control and two remote
controller control systems.

INSTALLATION SITE

■ Never place anything under the indoor unit that you
don't want to get wet.
The unit may sweat when the humidity is over 80% or
when the drain outlet is clogged.

■ Never place other heating equipment directly beneath
the indoor unit. Subject to deformation caused by
heat.

■ Do not place TV, radio, stereo, etc. within 1 meter from
the indoor unit and remote controller.
Doing so may cause interference in the picture or
sound.

■ Do not place objects in direct proximity of the outdoor unit and
do not let leaves and other debris accumulate around the unit.
Leaves are a hotbed for small animals which can enter the unit.
Once in the unit, such animals can cause malfunctions, smoke
or fire when making contact with electrical parts.

NAME AND FUNCTION OF EACH SWITCH AND

DISPLAY ON THE REMOTE CONTROLLER

Refer to the operation manual delivered with the remote
controller.

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 comfortable
environment. Avoid excessive heating or cooling.

■ Prevent direct sunlight from entering a room during cooling
operation by using curtains or blinds.

■ Keep doors and windows closed. If the doors and windows
remain open, room air will flow out and decrease the effect of
cooling and heating.

■ Never place objects near the air inlet and the air outlet of the
unit. It may retard effectiveness or cause operation to stop.

■ Tu rn off the main power supply switch when not using for long
periods of time. Electricity is consumed as long as the switch is
on. Turn off the main power supply switch in order to save
energy. Turn on the main power supply switch 6 hours before
restarting operation in order to ensure smooth operation. (Refer
to "Maintenance" on page 4.)

■ When the display shows " " (TIME TO CLEAN AIR
