• 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 

operation of the air conditioner, consult your 
local 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 piping 
and cause water leakage. If it occurs, stop the air 
conditioner and consult with your local dealer for 
assistance.

Operating procedure varies with heat pump type 
and cooling only type. Contact your local dealer to 
confirm your system type.

To protect the air conditioner, turn on the main 
power switch 6 hours before operation.

Do not shut off the power supply during seasonal 
use of the air conditioner.
This is required in order to activate the air condi-
tioner smoothly.

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

5-1. FUQ

Read the operation manual attached to the 
remote controller.

5-2. FXUQ

Read the operation manual attached to the out-
door unit and remote controller.

CHARACTERISTICS OF THE COOLING 
OPERATION (COOLING OPERATION AND 
AUTOMATIC COOLING OPERATION)

If the COOLING OPERATION is used when the 
indoor temperature is low, frost adheres to the 
heat exchanger of the indoor unit. 
This can decrease the cooling capacity. 
In this case, the air conditioner automatically 
switches to the DEFROST OPERATION for a 
while.

5. OPERATION PROCEDURE

6. OPERATION CHARACTERIS-

TICS

During the DEFROST OPERATION, the low fan 
speed or a gentle wind is used to prevent the dis-
charge of melt water. 
(The remote controller displays the fan speed that 
is set.) 

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 indoor temper-
ature of the HEATING OPERATION to reach the 
set temperature compared to the COOLING 
OPERATION.
It is advisable to start operation in advance using 
the TIMER OPERATION.

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

AT THE START OF OPERATION AND AFTER 
THE DEFROST 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 fan speed that 
is set.)

The airflow direction becomes horizontal to pre-
vent a draft of cool air to the inhabitants. (The 
remote controller displays the set airflow direction 
that is set.) 

DEFROST OPERATION
(Frost removal operation for the outdoor 
unit)

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

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

”.

With the wireless remote controller, the warm air 
stops, and the DEFROST OPERATION lamp on 
the light receiving unit turn on. 
(The remote controller displays the fan speed that 
is set.)

After maximum 10 minutes of the DEFROST 
OPERATION, the air conditioner returns to the 
HEATING OPERATION.
