FEATURES AND FUNCTIONS
■
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 the Economy operation is operated, the room
temperature will be little higher than the set-temp under the
Cooling mode and lower than set-temp under the Heating
mode. Therefore, the Economy operation is able to save more
energy than other normal operation.
OMNI-DIRECTIONAL AIRFLOW
(SWING OPERATION)
3-dimensional control over air direction swing is possible
through dual use of both the Up/down Swing operation and the
Left/right Swing operation. Since up/down air direction louvers
operate automatically according to the operating mode of the
unit, it is possible to set air direction based on the operating
mode.

outdoor unit:
The Economy indicator
lamp is blinking:
In following events, immediately stop operation of the air conditioner, and disconnect all the power
supply by turning off the electrical breaker or disconnecting the power plug. Then consult your
dealer or authorized service personnel.
As long as the unit is connected to the power supply, it is not insulated from the power supply
even if the unit is turned off .
Symptom Problem
●
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 fl 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
fl 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 the Heating mode 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 the Cooling mode or the Dry mode operation, a thin
mist may be seen emitted 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 the Heating mode 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 the Heating mode operation is started, fan speed is
temporarily very low, to allow internal parts to warm up.
●
*
During the Heating mode operation, if the room temperature
rises above the temperature 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 temperature to a higher
setting.
●
*
In the Heating mode, the indoor unit temporarily stops for
maximum of 15 minutes to perform the Automatic Defrosting
operation while the Operation indicator lamp is blinking.
●
The fan may operate at very low speed during the Dry
mode operation or when the unit is monitoring the room’s
temperature.
●
During the Super Quiet operation, the fan will operate at very
low speed.
●
When the Monitor operation is performed in the Auto mode,
the fan rotates at very low speed.
●
During the Heating mode operation, water may be produced
*
from the outdoor unit due to the Automatic Defrosting
operation.
●
Clean the air filter. Afterwards, turn the Economy indicator
lamp off .

OPERATING TIPS
Instructions relating to heating (*) are applicable only to Heating and Cooling model (Reverse Cycle).
Heating performance*
● This air conditioner operates on the heat-pump principle,
absorbing heat from air outdoors and transferring that heat
to the indoor unit. As a result, the operating performance is
reduced as outdoor air temperature drops. If you feel that the
heating performance is insuffi cient, we recommend you to use
this air conditioner in conjunction with other kinds of heating
appliance.
● Heat-pump air conditioners heat your entire room by
recirculating air throughout the room, with the result that some
time may be required after fi rst starting the air conditioner until
the room is heated.
When indoor and outdoor temperatures 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.
*
Automatic Defrosting operation*
● When 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
Defrosting operation. If frost forms, the air conditioner will
temporarily stop, and the defrosting circuit will operate briefl y
(for about 4 to 15 minutes).
During the Automatic Defrosting operation, the Operation
indicator lamp (green) will blink.
● After the Heating mode operation stops, if frost forms on
the outdoor unit, the unit will start the 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.
En-15
Hot start (for Heating mode)*
The indoor unit prevents cold drafts when the Heating mode
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.
OPERATING TIPS
The wired remote controller option is required to use the following function (**).
**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.
Instructions relating to heating (*) are applicable only to Heating and Cooling model (Reverse Cycle).
Auto restart
In event of power interruption
●
Should 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.
●
Should a power failure occur during the 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 blink.
●
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.
Simultaneous multi air conditioner
This indoor unit can also be connected to a simultaneous multi connection that enables simultaneous operation of multiple indoor
units by connecting the outdoor unit using a separation tube.
NOTES:
The number of connectable indoor units and connectable type of the separation tube vary by model.
In simultaneous multi connection, all indoor units can be operated simultaneously, from one remote controller connected to the
primary indoor unit.
For this unique characteristic of the simultaneous multi connection, the functions of other indoor units may be restricted.
Notices
●
*
During use of the Heating mode, the outdoor unit will
occasionally commence the Automatic Defrosting
operation for brief periods. During the Automatic Defrosting
operation, if the user sets the indoor unit for the Heating
mode again, the Automatic Defrosting operation will
continue, and the Heating mode 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.
