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
fluctuation 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 local dealer about snow
protection hoods, etc.
Regarding wiring
• All wiring must be performed by a qualified
personnel.
To do wiring, ask your local dealer. Never do it by
yourself.
• Make sure that a separate power supply cir­
cuit is provided for this air conditioner and
that all electrical work is carried out by quali­
fied 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
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
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
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.
System relocation
• Consult your Daikin dealer about remodelling
and relocation.
5. OPERATION PROCEDURE
• 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
conditioner smoothly.
• If the main power supply is turned off during
operation, operation will restart automatically
after the power turns back on again.
Read the operation manual attached to the
remote controller.
6. OPERATION CHARACTERISTICS
■
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
air conditioner 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.
