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 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 local dealer about snow
protection hoods, etc.
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 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
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.
4. INSTALLATION SITE
• 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 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.
5-1. FHQ
Read the operation manual attached to the
remote controller.
5-2. FXHQ
Read the operation manual attached to the out-
door unit and remote controller.
■ 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.
