Heating Performance*
MThis 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

heating performance is being produced, we recommend you
use this air conditioner in conjunction with another type of
heating appliance.
MHeat-pump air conditioners heat your entire room by recircu-
lating air throughout the room, with the result that some time
PD\EHUHTXLUHGDIWHU¿UVWVWDUWLQJWKHDLUFRQGLWLRQHUXQWLOWKH
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
to protect the unit.
Fan speed: AUTO
Heating*: The fan will operate at very low speed when the
temperature of the air issued from the indoor unit
is low.
Cooling : As the room temperature approaches that of the set
temperature, the fan speed becomes slower.
Fan : The fan runs at the low fan speed.
OPERATING TIPS
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
Microcomputer-controlled Automatic
Defrosting*
MWhen 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.

unit is equipped with a microcomputer-controlled automatic
defrosting function. During the defrost cycle, the indoor fan will
shutdown and will be displayed on the remote control-
OHU,WZLOOWDNHDQ\ZKHUHIURPWRPLQXWHVEHIRUHWKHDLU
conditioner starts up again.
MAfter 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, or one of the fans may stop intermittently.
Hot Start*
The indoor unit prevents cold drafts when heating operation
begins.
The indoor unit fan will not operate until the heat exchanger
reaches the set temperature.
Dual Remote Controllers (optional)
An additional remove controller can be added up to the maximum
of two remote controllers. Either remote controller can control
the air conditioner. However, the timer functions cannot be used
at the slave 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.

OPERATING TIPS
Mode operation
During heating mode:
Set the thermostat to a temperature set-
ting that is higher than the current room
temperature. The heating mode will not
operate if the thermostat is set lower than
the actual room temperature.
During cooling/dry mode:
Set the thermostat to a temperature set-
ting that is lower than the current room
temperature. The cooling and dry modes
will not operate if the thermostat is set
higher than the actual room temperature
(in cooling mode, the fan alone will ope-
rate).
During fan mode:
You can not use the unit to heat and cool
your room.
HEAT*: MUse to warm your room.
MWhen heating mode is selected, the air conditioner will operate at very
low fan speed for about 3 to 5 minutes, after which it will switch to the
selected fan setting. This period of time is provided to allow the indoor
unit to warm up before beginning full operation.
MWhen the outdoor temperature is very low, frost may form on the outdoor
unit, and its performance may be reduced. In order to remove such frost,
the unit will automatically enter the defrost cycle from time to time. During
automatic defrosting operation, the heat operation will be interrupted.

gets warmer.
COOL: MUse to cool your room.
DRY: MUse for gently cooling while dehumidifying your room.
MYou cannot heat the room during dry mode.
MDuring dry mode, the unit will operate at low speed; in order to adjust
room humidity, the indoor unit’s fan may stop from time to time. Also, the
fan may operate at very low speed when adjusting room humidity.
MThe fan speed cannot be changed manually when dry mode has been
selected.
FAN: MUse to circulate the air throughout your room.
AUTO [in HEAT & COOL (Reverse Cycle) model]:
MWhen AUTO (automatic changeover) is selected, the air conditioner selects the appropriate operation mode (cooling
or heating) according to your room’s present temperature.

MWhen the air conditioner has adjusted your room’s temperature to near the thermostat setting, it will begin monitor op-
eration. In the monitor operation mode, the fan will operate at low speed. If the room temperature subsequently chang-
es, the air conditioner will once again select the appropriate operation (heating, cooling) to adjust the temperature to
the value set in the thermostat.
MIf the mode automatically selected by the unit is not what you wish, select one of the mode operation (HEAT, COOL,
DRY, FAN).

ation. In the monitor operation mode, the fan will operate at low speed. If the room temperature subsequently changes,

OPERATING TIPS
MIf the power supply to the air conditioner is interrupted by a
power failure, the air conditioner will restart automatically in
the previously selected mode once the power is restored.
MUse 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, reconnect it, and then use the remote
controller to resume operation.

In Event of Power Interruption
Notices
*MDuring 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.
*MDuring use of the heating mode, the outdoor unit will oc-
casionally 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.
SELF-DIAGNOSIS
When “Er” in temperature indicator is displayed, inspection of the air conditioning system is necessary. Please consult authorized
service personnel.
