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. FHQ
Read the operation manual attached to the
remote controller.
5-2. FXHQ
Read the operation manual attached to the out-
door unit and remote controller.
CHARACTERISTICS OF THE COOLING
OPERATION (COOLING OPERATION AND
AUTOMATIC COOLING OPERATION)
•
When operating continuously at downward airflow
direction, air blows in the automatically set direc-
tion for a period of time to prevent condensation
on the horizontal blade. (The remote controller
displays the airflow direction that is set.)
•
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 air condi-
tioner automatically switches to the DEFROST
OPERATION for a while.
During the DEFROST OPERATION, the low fan
speed 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 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 airflow direc-
tion 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 con-
troller displays the fan speed that is set.)
•
After maximum 10 minutes of the DEFROST
OPERATION, the air conditioner returns to the
HEATING OPERATION.
•
The airflow direction becomes horizontal. (The
remote controller displays the airflow direction
that is set.)
•
During or after the DEFROST OPERATION, white
mist comes out from the air inlet or outlet of the air
conditioner.
(Refer to “
VI.
” on page 13.)
•
A hissing and “Shuh” sound may be heard during
this particular operation.
