CLEANING AND CARE
lBefore cleaning the unit, be sure to stop the unit and turn off the electrical breaker.
lA fan operates at high speed inside the unit, and personal injury could result.
CAUTION!
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 40 °C, harsh abrasive cleansers, or volatile agents like benzene
or thinner.
lDo not expose the unit body to liquid insecticides or hairsprays.
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.
Cleaning the Air Filter
lRemove the dust from the air filters by vacuuming or washing them. After washing, allow the air filters to dry thoroughly
in an area protected from sunlight.
lDust can be cleaned from the air filter either with a vacuum cleaner, or by washing the filter in a solution of mild detergent
and warm water. If you wash the filter, be sure to allow it to dry thoroughly in a shady place before reinstalling.
lIf dirt is allowed to accumulate on the air filter, air flow will be reduced, lowering operating efficiency and increasing
noise.
TROUBLESHOOTING
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the
electrical breaker, and consult authorized service personnel.
Merely turning off the unit’s power switch will not completely disconnect the unit from the power
source. Always be sure to turn off the electrical breaker to ensure that power is completely off.
WARNING!
Before requesting service, perform the following checks:

OPERATING TIPS
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
*Heating Performance
Low Ambient Cooling
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
insufficient heating performance is being produced, we
recommend you use this air conditioner in conjunction
with another kind of heating appliance.
lWhen 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 opera-
tion begins.
The indoor unit fan will not operate until the heat exchanger
reaches the set temperature.
lHeat-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.
About ECONOMY OPERATION
*When Indoor and Outdoor Tempera-
ture are High
At the maximum output, ECONOMY OPERATION is approxi-
mately 70% of normal air conditioner operation for cooling
and heating.
When ECONOMY OPERATION is performed during the
cooling mode, dehumidification is improved. This function
is especially convenient when you want to remove the
humidity in the room without significantly lowering the
room temperature.
lWhen both indoor and outdoor temperatures are high
during use of the heating mode, the outdoor unit’s fan
may stop at times.
Fan speed: AUTO
During ECONOMY OPERATION, the thermostat setting
automatically changes according to the temperature to avoid
Unnecessary cooling and heating for the most economical
operation.
lIf the room is not cooled (or heated) well during economy
operation, select normal operation.
*Heating: The fan will stop 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.
lDuring the monitor period in the AUTO mode, the air
conditioner operation will not change to ECONOMY
OPERATION even if ECONOMY OPERATION is selected
by pressing the ECONOMY button.
*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 per-
formance.
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.
In order to prevent this kind of reduced performance,
this 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 controller. It will take anywhere from 4 to
15 minutes before the air conditioner starts up again.
Group Control
One remote controller can control up to 16 air conditioners.
All of the air conditioners will be operated with the same
settings.
12
OPERATING TIPS
Mode operation: AUTO
COOLING MODEL
lWhen the room temperature is 2 °C higher than the set
temperature, the mode will switch between Cooling and
Drying.
lDuring 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.
HEAT & COOL MODEL (Reverse Cycle)
Auto changeover function
lWhen AUTO CHANGEOVER is selected, the air conditioner
selects the appropriate operation mode (Cooling or Heat-
ing) according to your room’s present temperature.
lWhen the room temperature is near the thermostat set-
ting, the air conditioner will begin monitor operation. In
the monitor operation mode, the fan will operate at 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 2 °C relative to the thermostat setting.)
lWhen AUTO CHANGEOVER is first selected, the fan will
operate at low speed for about 1 minute while the unit
determines the current conditions of the room and selects
the proper operation mode.
If the difference between thermostat setting and actual
room temperature is more than +2 °C
→ Cooling or dry operation
(Monitor operation may be selected if the outdoor
temperature is low.)
If the difference between thermostat setting and actual
room temperature is within 2 °C
→ Monitor operation
If the difference between thermostat setting and actual
room temperature is more than –2 °C
→ Heating operation
(Monitor operation may be selected if the outdoor
temperature is high.)
About 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.
*Heating:lUse to warm your room.
lWhen Heating mode is selected, the air conditioner will stop 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.
lWhen the room temperature is very low, frost may form on the outside
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.
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).
lAfter the start of heating operation, it takes sometime before the room
gets warmer.
Cooling: lUse to cool your room.
Dry: lUse for gently cooling while dehumidifying your room.
lYou cannot heat the room during Dry mode.
During Fan mode:
You can not use the unit to heat and cool
your room.
lDuring 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.
lThe fan speed cannot be changed manually when Dry mode has been
selected.
Fan: lUse to circulate the air throughout your room.
AUTO Restart
In Event of Power Interruption
lShould 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.
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
disconnect the power supply, reconnect it, and then use
the remote control unit to resume operation.
13
OPERATING TIPS
Notice
*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.
*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.
SELF-DIAGNOSIS
When “EE” in Temperature Display is displayed, inspection of the air conditioning system is necessary. Please consult
