• Make sure that a separate power supply circuit is provided for this air conditioner and that all electrical work is carried out by qualified personnel 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 mass

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 performance 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.

5. OPERATION PROCEDURE

Read the installation manual attached to the outdoor
unit and manual for remote controller.
Operating procedure varies with heat pump and
cooling only type. Contact your 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
conditioner smoothly.

• If the main power supply is turned off during

operation, operation will restart automatically
after the power turns back on again.

 CHARACTERISTICS OF THE COOLING

OPERA TION (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.
During the DEFROST OPERATION, the low fan
speed or a gentle wind is used to prevent the
discharge 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

temperature 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 heating capacity decrease and discha rge of cool air.

A T THE ST ART OF OPERA TION 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

prevent a draft of cool air to the inhabitants. (The
remote controller displays the set airflow direction
that is set.)
