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.
