places.
a.Filled with much mineral oil such as cutting oil
b.Where there is much salt such as a beach area
c.Where sulfured gas exists such as a hot-spring
resort
d.Where there are considerable voltage fluctua-
tions such as a factory or plant
e.Vehicles and vessels
f .Where there is much spray of oil and vapor
such as a cookery, etc.
g.Where there are machines generating electro-
magnetic waves
h.Filled with acid and/or alkaline steam or vapor
• Is a snow protection measure taken?
For details, consult your dealer.
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.
• 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 dealer.
Regarding drainage of drain piping
• Is the drain piping executed to perform com-
plete drainage?
If proper drainage is not carried out from the out-
door drain pipes during air-conditioning operation,
chances are that dust and dirt are clogged in the
pipe. This may result in a water leakage from the
indoor unit. Under such circumstances, stop the
operation of the air conditioner, and then consult
your dealer or our service station.
4. INSTALLATION SITE
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.
[EXPLANATION OF HEATING OPERATION]
DEFROST OPERATION
• 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 “
”.
• After 6 to 8 minutes (maximum 10 minutes) of
DEFROST OPERATION, the system returns to
HEATING OPERATION.
Regarding outside air temperature and heat-
ing capacity
• The heating capacity of the air conditioner
declines as the outside air temperature falls. In
such a case, use the air conditioner in combina-
tion with other heating systems.
• 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.
• An 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.
• When the warm air stays under the ceiling and
your feet are cold, we recommend that you use a
circulator (a fan to circulate the air inside the
room). For details, consult your dealer.
AIR FLOW DIRECTION ADJUST
• There are 2 ways of adjusting the air discharge
angle.
5. OPERATION PROCEDURE
A. Up and down adjustment
B. Left and right direction
