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.
10 °C HEAT OPERATION
The room temperature can be maintained at 10°C so as to prevent the room temperature from falling too far.
n
Convenient function
PROGRAM TIMER
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 airow is
reduced to produce quieter operation.
AUTO CHANGEOVER
The operation mode (cooling, dry, heating) is switched automatically to maintain the set temperature, and the temperature is kept constant at all times.
The program timer allows you to integrate OFF timer and ON
timer operations in a single sequence. The sequence can
involve 1 transition from OFF timer to ON timer, or from ON
timer to OFF timer, within a 24 hour period.
SLEEP TIMER
When the SLEEP timer button is pressed during Heating
mode, the air conditioner’s thermostat setting is gradually
lowered during the period of operation; during cooling or dry
mode, the thermostat setting is gradually raised during the
period of operation. When the set time is reached, the unit
automatically turns off.

source. Always be sure to disconnect the power supply plug or turn off your circuit breaker to ensure that power is completely off.
NORMAL
FUNCTION
Symptom Problem
Does not operate
immediately:
Noise is heard:
Smells:
Mist or steam are
emitted:
Airow is weak or stops:
Water is produced from the
outdoor unit:
The ECONOMY indicator
lamp ashing:
●
If the unit is stopped and then immediately started again, the
compressor will not operate for about 3 minutes, in order to
prevent fuse blowouts.
●
Whenever the power supply plug is disconnected and then
reconnected to a power outlet, the protection circuit will operate for about 3 minutes, preventing unit operation during that
period.
●
During 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 owing).
●
During 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.
●
*
During heating operation, a sizzling sound may be heard occasionally. This sound is produced by the automatic defrosting
operation.
●
Some 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.
●
During 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, resulting in condensation and misting.
●
*
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.
●
*
When heating operation is started, fan speed is temporarily
very low, to allow internal parts to warm up.
●
*
During heating operation, if the room temperature rises above
the thermostat setting, the outdoor unit will stop, and the
indoor unit will operate at very low fan speed. If you wish to
warm the room further, set the thermostat to a higher setting.
●
*
During heating operation, the unit will temporarily stop operation (Max. 15 minutes) as the automatic defrosting mode
operates. During the automatic defrosting operation, the OP-
ERATION indicator lamp will ash.
●
The fan may operate at very low speed during dry operation
or when the unit is monitoring the room’s temperature.
●
During SUPER QUIET operation, the fan will operate at very
low speed.
●
In the monitor AUTO operation, the fan will operate at very
low speed.

OPERATING TIPS
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
Heating Performance*
● This 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 insufcient
heating performance is being produced, we recommend you
use this air conditioner in conjunction with another kind of
heating appliance.
● Heat-pump air conditioners heat your entire room by recir-
culating 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.
The wired remote controller option is required to use the following function (**).
Microcomputer-controlled Automatic Defrosting
● When using the heating mode under conditions of low out-
door 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
defrosting function. If frost forms, the air conditioner will
temporarily stop, and the defrosting circuit will operate
briey (for about 4 to 15 minutes).
During automatic defrosting operation, the OPERATION
indicator lamp will ash.
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.
*
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.
AUTO Restart
In Event of Power Interruption
● Should the power supply to the air conditioner be inter-
rupted by a power failure, the air conditioner will restart
automatically in the previously selected mode once the
power is restored.
● Should 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 will ash.
● Use 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
disconnect the power supply plug, reconnect it, and then
use the remote controller to resume operation.
Notices
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
*● During use of the heating mode, the outdoor unit will occa-
sionally 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.
● During use of the heating mode, the top of the indoor unit
*
may become warm, but this is due to the fact that coolant is
circulated through the indoor unit even when it is stopped;
it is not a malfunction.
