Regarding wiring
•
All wiring must be performed by an qualified
personnel.
To do wiring, ask your local 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 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 neighbors.
•
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, 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 manual attached to the remote controller.
•
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.
6. OPERATION CHARACTERISTICS
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 tem-
perature 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 heat exchanger of an outdoor
unit increase, heating effect decreases and the air
conditioner goes into the DEFROST OPERA-
TION.
•
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.)
