Regarding wiring

• All wiring must be performed by an authorized 

electrician.

To do wiring, ask your dealer. Never do it by yourself.

• Make sure that a separate power supply circuit 

is provided for this air conditioner and that all 
electrical work is carried out by qualified per-
sonnel according to local laws and regulations.

Pay attention to running noises, too

• Are the following places selected?

a. A place that can sufficiently withstand the 

weight of the air conditioner with less running 
noises and vibrations.

b. A place where the hot wind discharged from the 

air outlet of the outdoor unit and the running 
noises do not cause a nuisance to neighbours.

• Are you sure that there are no obstacles near 

the air outlet of the outdoor unit?

Such obstacles may result in declined perfor-
mance and increased running noises.

• If abnormal noises occur in use, stop the oper-

ation of the air conditioner by remote control-
ler, consult your dealer.

Regarding drainage of drain piping

• Is the drain piping carried out properly to 

ensure complete drainage?

If drain piping is not carried out properly, dirt and 
debris may be accumulated in the drain pipe and 
cause water leakage. If it occurs, stop the air con-
ditioner and consult with your dealer for assis-
tance.

Read the operation manual that came with 
the remote controller.

Operating procedure varies with heat pump type 
and cooling only 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 oper-
ation, operation will restart automatically after the 
power turns back on again.

5. OPERATION PROCEDURE

[CHARACTERISTICS OF THE COOLING 

OPERATION (COOLING OPERATION AND 

AUTOMATIC COOLING OPERATION)]

If the COOLING OPERATION is used when the 
indoor temperature is low, frost forms on the heat 
exchanger of the indoor unit. This can decrease 
the cooling capacity. In this case, the system 
automatically switches to DEFROST OPERA-
TION for a while.
Low airflow rate is used prevent humidity increase.

When the outdoor temperature is high, it takes 
some time until the indoor temperature reaches 
the set temperature.

[CHARACTERISTICS OF THE HEATING 

OPERATION (HEATING OPERATION AND 

AUTOMATIC HEATING OPERATION)]

START OF OPERATION

It generally takes a longer time for HEATING 
OPERATION to reach the set temperature com-
pared to COOLING OPERATION. It is advisable 
to start operation in advance using TIMER OPER-
ATION.

Perform the following operation to prevent heat-
ing capacity decrease and discharge of cool air.

AT THE START OF OPERATION AND AFTER 

DEFROSTING OPERATION

A warm air circulating system is employed, and 
therefore it takes some time until the entire room 
is warmed up after the start of operation.

The indoor fan runs to discharge a gentle wind 
automatically until the temperature inside the air 
conditioner reaches a certain level. At this time, 
the remote controller displays “

”. Leave it 

as it stands and wait for a while.

The remote controller displays the airflow rate 
that is set.

DEFROST OPERATION (Frost removal oper-

ation for the outdoor unit)

As the frost on the coil of an outdoor unit increase, 
heating effect decreases and the system goes 
into DEFROST OPERATION.

The indoor unit fan stops and the remote control-
ler display shows “

”.

The remote controller displays the airflow rate 
that is set.

After 6 to 8 minutes (maximum 10 minutes) of 
DEFROST OPERATION, the system returns to 
HEATING OPERATION.
