CAUTION!
Cleaning the Intake Filters
1. Remove the intake filters.
1 Place fingers in grids on the front of the intake filters
and lift up.
2 Hold the intake filters level and pull them out.
2. Clean the intake filters.
Remove the dust from the intake filters by vacuuming or
washing them. After washing, allow the intake filters to
dry thoroughly in an area protected from sunlight.
● Dust can be cleaned from the intake filters either with a
vacuum cleaner, or by washing the filters in a solution of
mild detergent and warm water. If you wash the filters,
be sure to allow them to dry thoroughly in a shady place
before reinstalling.
● If dirt is allowed to accumulate on the intake filters, air
flow will be reduced, lowering operating efficiency and
increasing noise.
● During periods of normal use, the intake filters should be
cleaned every five weeks.
3. Install the intake filters.
Hang the edge of the intake filter on the body. Using this
as a support point, push forward to secure as shown in
the illustration.
When using the optional Air Cleaning Filter
● Install the optional air cleaning filter set as instructed (installation instructions are furnished with the air cleaning filter set).
● When 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.
● When cleaning the unit’s body, do not use water hotter than 40 °C, harsh abrasive cleansers, or volatile agents like
benzene or thinner.
● Do not expose the unit body to liquid insecticides or hairsprays.
● When shutting down the unit for one month or more, first allow the fan mode to operate continuously for about one-half
day to allow internal parts to dry thoroughly.

TROUBLESHOOTING
Instructions relating to heating (*) are applicable to “HEAT PUMP MODEL” and “HEAT RECOVERY MODEL”.
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.
Before requesting service, perform the following checks:
Symptom
Doesn’t operate immediately:
Noise is heard:
Smells:
Mist or steam are
emitted:
Airflow is weak or stops:
Water is produced from
the outdoor unit:
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 electrical breaker is turned off then on again, 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 flowing 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 flowing).
● 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 occa-
sional. 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 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 Heating operation, the outdoor unit’s fan may stop, and
steam may be seen rising from the unit. This is due to Automatic
Defrosting operation.
*● When Heating operation is started, indoor unit’s fan may stop, 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’s fan will stop. If you wish to warm the room further, set the
thermostat for a higher setting.
*● During Heating operation, the unit will temporarily stop opera-
tion (between 2 and 16 minutes) as the Automatic Defrosting mode
operates. During Automatic Defrosting operation, the OPERATION
indicator lamp will flash.
● The fan may operate at low speed during Dry operation or when
the unit is monitoring the room’s temperature.
● In the monitor AUTO operation, the fan will operate at low speed.
*● During Heating operation, water may be produced from the out-
door unit due to Automatic Defrosting operation.

CHECK ONCE
MORE
Items to check
● Has there been a power failure?
● Has a fuse blown out, or a circuit breaker been tripped?
● Is the main power switch set to the OFF position?
● Is the timer operating?
● Is the air filter dirty?
● Are the air conditioner’s intake grille or outlet port blocked?
● Did you adjust the room temperature settings (thermostat) cor-
rectly?
● Is there a window or door open?
● In the case of Cooling operation, is a window allowing bright sun-
light to enter? (Close the curtains.)
● In the case of Cooling operation, are there heating apparatus and
computers inside the room, or are there too many people in the
room?
If the problem persists after performing these checks, or if you notice burning smells, stop operation immediately, turn off the
electrical breaker, and consult with authorized service personnel.
OPERATING TIPS
*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.
Cooling/Heating Priority (HEAT PUMP MODEL only)
● If another indoor unit in the same refrigerant system is
already operating in the cooling mode or dry mode, heating mode settings cannot be performed. (Operation in
the cooling or dry mode will continue.)
● If another indoor unit in the same refrigerant system is
already operating in the heating mode, cooling mode or
dry mode settings cannot be performed. (Operation in
the heating mode will continue.)
Operation and Performance
*Microcomputer-controlled Automatic Defrosting
When using the Heating mode under conditions of low outdoor air temperature 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
briefly (for about 2 to 16 minutes).
During Automatic Defrosting operation, the OPERATION indicator lamp (red) will flash.
Oil Recovery Operation
Periodically, the oil recovery operation is performed in order to return compressor oil to the outdoor unit. Operation
is stopped during this oil recovery operation. During oil recovery operation, the OPERATION indicator lamp will flash.
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.
