FEATURES AND FUNCTIONS
n Energy saving and Comfortable function
INVERTER
At the start of operation, large amount of power is used to
bring the room quickly to the desired temperature. Afterwards,
the unit automatically switches to a low power setting for
economic and comfortable operation.
ECONOMY OPERATION
When ECONOMY operation mode is operated, the room
temperature will be little higher than the set-temp under
cooling mode and lower than set-temp under heating mode.
Therefore, the ECONOMY mode is able to save more energy
than other normal mode.
OMNI-DIRECTIONAL AIR FLOW
(SWING OPERATION)
3-dimensional control over air direction swing is possible
through dual use of both an up/down air direction swing and
right/left air direction swing. Since up/down air direction aps
operate automatically according to the operating mode of the
unit, it is possible to set air direction based on the operating
mode.
SUPER QUIET OPERATION
When the FAN button is used to select QUIET, the indoor
unit begins super quiet operation; the indoor unit’s airow is
reduced to produce quieter operation.
AUTO CHANGEOVER
The operation mode (cooling, dry, heating) is switched auto-
matically to maintain the set temperature, and the temperature
is kept constant at all times.

NORMAL
FUNCTION
Does not operate imme-
diately:
lIf the unit is stopped and then immediately started again, the
compressor will not operate for about 3 minutes, in order to
prevent fuse blowouts.
lWhenever the power supply plug is disconnected and then
reconnected to a power outlet, the protection circuit will oper-
ate for about 3 minutes, preventing unit operation during that
period.
—
Noise is heard: lDuring operation and immediately after stopping the unit, the
sound of water owing in the air conditioner’s piping may be
heard. Also, noise may be particularly noticeable for about 2
to 3 minutes after starting operation (sound of coolant ow-
ing).
lDuring operation, a slight squeaking sound may be heard.
This is the result of minute expansion and contraction of the
front cover due to temperature changes.
—
*l During heating operation, a sizzling sound may be heard oc-
casionally. This sound is produced by the automatic defrosting
operation.
16
Smells: lSome smell may be emitted from the indoor unit. This smell is
the result of room smells (furniture, tobacco, etc.) which have
been taken into the air conditioner.
—
Mist or steam are
emitted:
lDuring cooling or dry operation, a thin mist may be seen emit-
ted from the indoor unit. This results from the sudden Cooling
of room air by the air emitted from the air conditioner, result-
ing in condensation and misting.
—
*l During heating operation, the outdoor unit’s fan may stop,
and steam may be seen rising from the unit. This is due to the
automatic defrosting operation.

TROUBLESHOOTING
OPERATING TIPS
Heating Performance*
lThis air conditioner operates on the heat-pump principle,
absorbing heat from outdoor air and transferring that heat
indoors. As a result, the operating performance is reduced
as outdoor air temperature drops. If you feel that insufcient
heating performance is being produced, we recommend you
use this air conditioner in conjunction with another kind of
heating appliance.
lHeat-pump air conditioners heat your entire room by recircu-
lating air throughout the room, with the result that some time
may be required after rst starting the air conditioner until the
room is heated.
When Indoor and Outdoor Temperature are High *
When both indoor and outdoor temperatures are high during use
of the heating mode, the outdoor unit’s fan may stop at times.
Microcomputer-controlled Automatic Defrosting *
lWhen using the heating mode under conditions of low outdoor
temperature and high humidity, frost may form on the outdoor
unit, resulting in reduced operating performance.
In order to prevent this kind of reduced performance, this unit is
equipped with a microcomputer-controlled automatic defrost-
ing function. If frost forms, the air conditioner will temporarily
stop, and the defrosting circuit will operate briey (for about
4 to 15 minutes).
During automatic defrosting operation, the OPERATION
indicator lamp (green) will ash.
lAfter heating operation stops, if frost forms on the outdoor
unit, the unit will start automatic defrosting operation. At this
time, the outdoor unit will automatically stop after operating
for a few minutes.
Low Ambient Cooling*
When the outdoor temperature drops, the outdoor unit’s fans
may switch to low speed.
Hot Start (for heating)*
The indoor unit prevents cold drafts when heating operation
begins.
The indoor unit fan will not operate or it will operate at a very low
speed until the heat exchanger reaches the set temperature.
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).

OPERATING TIPS
AUTO Restart
In Event of Power Interruption
lShould the power supply to the air conditioner be
interrupted by a power failure, the air conditioner will restart
automatically in the previously selected mode once the
power is restored.
lShould a power failure occur during TIMER operation, the
timer will be reset and the unit will begin (or stop) operating
under the new timer setting. In this event, the TIMER
indicator lamp (orange) will ash.
lUse of other electrical appliances (electric shaver, etc.) or
nearby use of a wireless radio transmitter may cause the air
conditioner to malfunction. In this event, temporarily discon-
nect the power supply plug, reconnect it, and then use the
remote controller to resume operation.
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
**Dual Remote Controllers (optional)
An additional remote controller can be added up to the maximum of 2 remote controllers. Either remote controller can control the air
conditioner. However, the timer functions cannot be used at the secondary unit.
**Group Control
1 remote controller can control up to 16 air conditioners. All of the air conditioners will be operated with the same settings.
The wired remote controller option is required to use the following function (**).
*lDuring use of the heating mode, the top of the indoor unit
may become warm, but this is due to the fact that cool-
ant is circulated through the indoor unit even when it is
stopped; it is not a malfunction.
*lDuring use of the heating mode, the outdoor unit will
occasionally commence the defrost operation for brief
periods. During the defrosting operation, if the user sets
the indoor unit for heating again, the defrosting mode
will continue, and the heating operation will begin after
completion of defrosting, with the result that some time
may be required before warm air is emitted.
