OPERATING TIPS
Instructions relating to heating are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
Mode operation: AUTO
AUTO restart
COOLING MODEL
• 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.
• When the room temperature is 4 °F higher than the set
temperature, the mode will switch between Cooling and
Drying.
• During the Drying mode operation, the FAN setting should
be switched to LOW for a gently cooling effect during
which the fan may temporarily stop rotating.
• 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
turn off the circuit breaker turn it on again and then use
the remote controller to resume operation.
HEAT & COOL MODEL (Reverse Cycle)
Auto changeover function
• When AUTO CHANGEOVER is selected, the air conditioner
selects the appropriate operation mode (Cooling or
Heating) according to your room’s present temperature.
• When AUTO CHANGEOVER is first selected, the fan will
stop or operate at a very low speed for about 1 minute
while the unit determines the current conditions of the
room and selects the proper operation mode.
• When the room temperature is near the thermostat
setting, the air conditioner will begin monitor operation.
In the monitor operation mode, the fan will stop or operate
at a very low speed. If the room temperature subsequently
changes, the air conditioner will once again select the
appropriate operation (Heating or Cooling) to adjust
the temperature to the value set in the thermostat. (The
monitor operation range is 4 °F relative to the thermostat
setting.)
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
insufficient 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
recirculating air throughout the room, with the result
that some time may be required after first starting the
air conditioner until the room is heated.
Fan speed: AUTO
Heating: The fan will stop or operate at a very low speed
if the temperature of the airflow from the indoor
unit is lower than the set temperature.
Cooling: As the room temperature approaches that of the
set temperature, the fan speed becomes slower.
Fan:
The fan alternately turns on and off; when on, the
fan runs at the low fan speed.

OPERATING TIPS
Energy save
Hot start (for heating)
• The energy conservation mode (ENERGY SAVE) raises the
set temperature slightly in the cooling mode and lowers
the set temperature in the heating mode to economically
control the operation of the unit.
• If you press the ENERGY SAVE button while the unit is
in the timer mode, the unit will go into the conservation
mode when the unit starts with the timer.
• If you turn off the air conditioner while in the conservation
mode, the mode will be shut off.
• The temperature set on the remote controller will not
change if the energy save mode is used.
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.
Defrosting (for heating)
When the outdoor temperature is low and the humidity
high, frost will collect on the outdoor unit, reducing heater
efficiency.
When this happens, the computer will automatically start
the defrost cycle. During the defrost cycle, the indoor fan

OPERATING TIPS
Multi-type Air conditioner
This indoor unit can be connected to a multi-type outdoor unit. The multi-type air conditioner allows multiple indoor units
to be operated in multiple locations. The indoor units may be operated simultaneously, in accordance with their respective
output.
Simultaneous Use of Multiple Units
Instructions relating to inverter (v) are applicable only to “INVERTER MODEL”.
v
lOperation can be done in the following different
operating modes.
l
When using a multi-type air conditioner, the multiple
indoor units can be operated simultaneously, but when
two or more indoor units of the same group are operated
simultaneously, the heating and cooling efficiency will
be less than when a single indoor unit is used alone.
Accordingly, when you wish to use more than one indoor
unit for cooling at the same time, the use should be
concentrated at night and other times when less output
is required. In the same way, when multiple units are
used simultaneously for heating, it is recommended that
they be used in conjunction with other auxiliary space
heaters, as required.
Seasonal and outdoor temperature conditions, the
structure of the rooms and the number of persons present
may also result in differences of operating efficiency.
We recommend that you try various operating patterns
in order to confirm the level of heating and cooling
output provided by your units, and use the units in the
way that best matches your family’s lifestyle.
Cooling mode and dry mode
Cooling mode and fan mode
Dry mode and fan mode
v
lThe operating mode (heating mode or cooling (dry) mode)
of the outdoor unit will be determined by the operating
mode of the indoor unit that was operated first.
If the indoor unit was started in fan mode, the operating
mode of the outdoor unit will not be determined.
For example, if indoor unit (A) was started in fan mode
and then indoor unit (B) was then operated in heating
mode, indoor unit (A) would temporarily start operation
in fan mode but when indoor unit (B) started operating
l
in heating mode,
will be shown on the remote
controller display and it would go into standby mode.
Indoor unit (B) would continue to operate in heating
mode.
l
lf you discover that one or more units delivers a low level
of cooling or heating during simultaneous operation, we
recommend that you stop simultaneous operation of the
multiple units.
v
lOperation cannot be done in the following different
operating modes.
If the indoor unit is instructed to do an operating mode
that it cannot perform,
will be shown on the remote
controller display and the unit will go into the standby
mode.

Heating mode and fan mode
Notice
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
*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.
*lDuring 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.

CARE AND MAINTENANCE
CAUTION!
Before cleaning the unit, be sure to stop the unit and power supply. (Turn off the electrical breaker)
Cleaning the air filter
If dirt is allowed to collect in the air filter, the airflow will be reduced, leading to reduced performance, and increased
operation noise. Be sure to clean the filters regularly.
How to cleaning
Use a vacuum cleaner to remove dust and dirt from the air filter, or wash in a synthetic detergent. After washing, dry in a
shaded place, then reinstall.
lWhen used for extended periods, the unit may accumulate dirt inside, reducing its performance. We recommend that
the unit be inspected regularly, in addition to your own cleaning and care. For more information, consult authorized
service personnel.
lWhen cleaning the unit’s body, do not use water hotter than 104 °F, harsh abrasive cleansers, or volatile agents like
benzene or thinner.
lDo not expose the unit body to liquid insecticides or hairspray.
lIf the unit will not be operated for a period of one month or more, be sure to allow the inner parts of the unit to dry
thoroughly, in advance, by operating the unit in fan mode for half a day.
