4. INSTALLATION SITE
Regarding places for installation
• Is the air conditioner installed at a well-ventilated
place where there are no obstacles around?
• Do not use the air conditioner in the following 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 fluctuations
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 electromagnetic
waves
h. Filled with acid and/or alkaline steam or vapor
• Is a snow protection measure taken?
For details, consult your dealer about snow protection
hoods, etc.
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 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 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 performance and
increased running noises.
• If abnormal noises occur in use, stop the operation
of the air conditioner, consult your dealer.
System relocation
• Consult your Daikin dealer about remodelling and
relocation.
Regarding drainage of drain pipe
• Is the drain pipe executed to perform complete
drainage?
If proper drainage is not carried out from the outdoor 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.
5. OPERATION PROCEDURE
• Operation procedure
Read the operation manual attached to the remote
controller.
• Operation procedure varies with heat pump type and
cooling only type. Contact your local dealer to confirm
your system type.
• To protect the unit, turn on the main power supply 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 switch is turned off during
operation, operation will restart automatically after the
power turns back on again.
6.OPERA TION 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 direction
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.
• When the outdoor temperature is high, it takes some time
until the indoor temperature reaches the set temperature.
■ CHARACTERISTICS OF THE PROGRAM DRY
OPERATION
• This operation lowers the humidity without lowering the
indoor temperature. The indoor temperature, when the
operation button is pressed,will be the set temperature.
At this time, the fan speed and temperature are set
automatically, so the remote controller does not display
the fan speed and set temperature.
To efficiently lower the indoor temperature and humidity,
first use the COOLING OPERATION to lower the indoor
