Warning
If refrigerant gas blows off during the work, do not touch the refrigerant gas as it may cause frostbite.
Prohibit
If refrigerant gas leaks during the work, ventilate the room.
If refrigerant gas catches fire, harmful gas may be generated.
Do not mix any gas other than the specified refrigerant gas in the refrigerating cycle.
If air or other contaminants mix with the gas, pressure will become extremely high in the refrigerating cycle,
which may cause a unit breakdown."
Prohibit
When the welded section of the compressor intake or discharge pipe is to be disconnected, perform it in
a well-ventilated place after sufficiently recovering the refrigerant gas.
Any residue gas may jet out refrigerant or refrigerating machine oil, which may cause an injury.
When the work is to be performed in a high place (About 2 meters or more), make sure to wear a safety helmet,
gloves and safety belt. Insufficient safety gear may cause a serious injury in case of a fall.
When the unit is to be relocated, confirm that the new installation location has sufficient strength for the weight of the unit.
Insufficient strength of the installation location and incomplete installation work may cause an injury due to
the unit falling.
When the remote controller batteries are replaced, dispose of the old batteries out of the reach of children.
If a child swallows a battery, make sure that the child gets immediate medical attention.
Caution
Do not wash the air conditioner with water, as this may cause an electric shock or fire.
Prohibit
For the repair work in places with high humidity or moisture, make sure to ground the unit.
Failure to do so may cause an electric shock.
Confirm that the component attachment position, wiring condition, soldering condition and connector connection
are normal.
If not, it may cause overheating or fire.
Confirm that the temperature around the compressor is not too high, and then perform the repair work.
Failure to do so may cause a burn.
Perform welding work in a place with good ventilation.
If the work is performed in a poorly ventilated area, it might cause a lack of oxygen.
If the installation plate or attachment frame has deteriorated due to corrosion, etc., replace it.
Failure to do so may cause an injury due to the unit falling.
When the cleaning is to be performed, make sure to turn off the power and pull out the plug.
Touching the fan that is rotating at high speed may result in an injury.
When the indoor unit is to be removed, do not place it on an incline.
Doing so may cause wet furniture because water left inside may trickle down.
Prohibit
Prohibit
Do not hold the sharp end of the unit or the aluminum fins, as it may cause an injury to your hand or finger.
After repairs, make sure to measure the insulation resistance and confirm that the value is 1 Mohm or more.
Any insulation error may cause an electric shock.
After repairs, make sure to check the drainage of the indoor unit.
Inappropriate drainage may cause wet furniture and floors due to water leakage.

temperature in the case of cooling operation. The flap and
fan speed settings are AUTO.
Conditions are monitored at all
times when the room temperature
is below 59°F(15°C).
DRY A
The compressor operation frequency varies.
The indoor fan operates with 1/f fluctuation.
DRY B
The compressor operates at a low operating frequency.
The indoor fan operates with 1/f fluctuation.
Monitor
• Monitoring operation takes place when the room temperature
is below 59°F
temperature.
(15°C), or more than 5°F(3°C) below the set
• When the monitoring range is entered, the compressor stops,
and the indoor fan operates with 1/f fluctuation.
PAM- control
• In order to further improve inverter performance, control is
switched between PWM control at low operation speeds, and
PAM control at high operation speeds, making the most
effective use of power.

HIGH POWER
NIGHT SETBACK
This function acts to raise the power but keeps the AC system in
the same operating mode.
This function is set with the HIGH POWER button on the remote
controller.
(It can be set regardless of the temperature and fan speed
settings.)
When NIGHT SETBACK operation is set, the temperature and
fan speed settings will be adjusted automatically to allow
comfortable sleep.
When NIGHT SETBACK operation is set, " mark" appears on
the remote controller. The main unit display lamp also becomes
dimmer.
HIGH POWER operation from remote controller
COOL and DRY modes
The unit operates at maximum output for 30 minutes,
regardless of the desired temperature.
The fan speed is 1 step above "High."
When the night setback mode is selected, the air conditioner
automatically raises the temperature setting 2°F(1°C) when 30
minutes have passed after the selection was made, and then
another 2°F(1°C) after another 30 minutes have passed,
regardless of the indoor temperature when night setback was
selected. This enables you to save energy without sacrificing
comfort. This function is convenient when gentle cooling is
needed.

8. TROUBLESHOOTING
8-1. Precautions before Performing Inspection or Repair
After checking the self-diagnostics monitor, turn the power OFF before starting inspection or repair.
High-capacity electrolytic capacitors are used inside the outdoor unit controller (inverter). They retain an electrical charge
(charging voltage DC 310V) even after the power is turned OFF, and some time is required for the charge to dissipate. Be
careful not to touch any electrified parts before the controller LED (red) turns OFF.
If the outdoor controller is normal, approximately 30 seconds will be required for the charge to dissipate. However, allow
at least 5 minutes for the charge to dissipate if there is thought to be any trouble with the outdoor controller.
8-2. Method of Self-Diagnostics
< Clock display >
Follow the procedure below to perform detailed trouble diagnostics.
Test run mode
Self-diagnostics mode
NOTE
1:If the operation lamp blinks every 0.5 seconds immediately when the
power is turned ON, there is an external ROM (OTP data) failure on the
indoor circuit board, or a ROM socket insertion problem, or the ROM
has not been installed.
2:The failure mode is stored in memory even when the power is not ON.
Follow the procedure below to perform diagnostics.
PROCEDURE
ON/OFF
operation
button
After turning on power to the air conditioner, use the remote controller and
follow the steps below to execute self-diagnostics.
Step 1: Press and hold the remote controller HIGH POWER button and 1
HR TIMER button. Then, press and hold the ACL (reset) button
with a pointed object such as the tip of a pen. After 5 seconds,
release ACL button first, then release HIGH POWER and 1 HR
TIMER buttons, "oP-1" (test run) appears, blinking in the remote
controller clock display area.
HIGH POWER
button
1HR.
TIMER
button
Step 2: Next, press the 1 HR TIMER button once to change the display
from "oP-1" to "oP-3" (self-diagnostics). (The display continues to
blink.)
Step 3: Finally press the ON/OFF button to engage self-diagnostics mode.
• The self-diagnostics function utilizes the 3 indicator lamps on the main
unit, in combinations of ON lamps, blinking lamps, and OFF lamps, to
report the existence of sensor trouble or a protective operation. (The
lamps blink or remain ON for 5 seconds, then turn OFF for 2 seconds.)
Self-diagnostics is completed when the buzzer sounds 3 short beeps.
• A maximum of 3 self-diagnostics reports are displayed, for 5 seconds
each, beginning with the most recent report. Following this display the
lamps turn OFF. In order to view the self-diagnostics results again,
press the ON/OFF button again.
ACL
(Reset)
button
• The 3 lamps remain OFF if no trouble has occurred.
<IMPORTANT> After self-diagnostics is completed, be sure to press the
ACL (reset) button to return to normal mode. The air
conditioner will not operate if this is not done.

8-4. Trouble Diagnosis of Fan Motor
8-4-1. Indoor Fan Motor
This indoor DC fan motor contains an internal control PCB. Therefore, it is not possible to measure the coil
resistance, and the following procedure should be used to check the motor.
To perform diagnosis, operate the unit in cooling mode with indoor fan speed "High". Next, make sure that the
indoor unit receive the signals from the remote controller when the ON/OFF operation button is pressed.
Important:
(A) Turn OFF the power before connecting or disconnecting the motor connectors.
(B) When performing voltage measurement at the indoor controller connector for (3) in the table
below, the DC motor will trip and voltage output will stop approximately 1 minute after operation
is started. For this reason, to measure the voltage again, turn OFF the unit once using the
remote controller, and then start the air conditioner again.
[Trouble symptom 1] The fan does not stop when the unit stops. Indoor unit controller trouble.
[Trouble symptom 2] The fan motor does not rotate when the unit is operating.
(Diagnostic procedure)
* Disconnect the motor connectors and measure the voltage at the DC motor connectors on the indoor
unit controller (3 locations).
Measurement location
Normal value
DC 280V to 340V
(1) Vm-Gnd: Between pin 1 and pin 3
(2) Vcc-Gnd: Between pin 4 and pin 3
(3) Vs-Gnd: Between pin 5 and pin 3
DC 15V +/- 10%
Fluctuation between DC 1.8V to 5.7V
(Diagnostic results)
All of the above measured values are normal. Fan motor trouble (Replace the motor.)
Any one of the above measured values is not normal. Indoor unit controller trouble (Replace the controller .)
(Reference)
DC motor connector pin arrangement
Pin 1: Vm (red)
Pin 2: Not used
Pin 3: Gnd (black)
Pin 4: Vcc (white)
Pin 5: Vs (yellow)
Pin 6: PG (blue)
[Trouble symptom 3] Motor rotates for some time (several seconds), but then quickly stops, when the indoor
unit operates.
(There is trouble in the system that provides feedback of motor rotation speed from the
motor to the indoor unit controller.)
[Trouble symptom 4] Fan motor rotation speed does not change during indoor unit operation.
[Trouble symptom 5] Fan motor rotation speed varies excessively during indoor unit operation.
(Remedy for symptom 3 to 5)
It is not possible to identify whether the trouble is indoor unit controller trouble or motor trouble.
Therefore, first replace the indoor unit controller, then (if necessary) replace the DC motor.

8-5. Noise Malfunction and Electromagnetic Interference
An inverter A/C operates using pulse signal control and high frequencies. Therefore, it is susceptible to the effects of external
noise, and is likely to cause electromagnetic interference with nearby wireless devices.
A noise filter is installed for ordinary use, preventing these problems. However, depending on the installation conditions, these
effects may still occur. Please pay attention to the points listed below.
(1) Noise malfunction
This refers to the application of high-frequency noise to the signal wires, resulting in abnormal signal pulses and malfunction.
Locations most susceptible to noise
Trouble
Correction
1. Locations near broadcast stations where
there are strong electromagnetic waves
Either of the following trouble may occur.
(The fundamental concept is to make the
system less susceptible to noise.)
1. The unit may stop suddenly during
operation.
2. Locations near amateur radio (short wave)
stations
- Insulate for noise or
distance from the noise source. -
2. Indicator lamps may flicker.
3. Locations near electronic sewing machines
and arc-welding machines
1. Use shielded wires.
2. Move unit away from the noise source.
(2) Electromagnetic interference
This refers to noise generated by high-speed switching of the microcomputer and compressor. This noise radiates through
space and returns to the electric wiring, affecting any wireless devices (televisions, radios, etc.) located nearby.
Locations most susceptible to noise
Trouble
Correction
1. A television or radio is located near the
A/C and A/C wiring.
1. Noise appears in the television picture, 1. Select a separate power source.
or the picture is distorted.
2. Keep the A/C and A/C wiring at least 1 meter
away from wireless devices and antenna cables.
2. The antenna cable for a television or
radio is located close to the A/C and A/C
wiring.
2. Static occurs in the radio sound.
3. Change the wireless device’s antenna to a high-
sensitivity antenna.
3. Locations where television and radio
signals are weak.
4. Change the antenna cable to a BS coaxial cable.
5. Use a noise filter (for the wireless device).

SPECIAL REMARKS
‘‘DRY’’ ( ) Operation
How it works?
• Once the room temperature reaches the level that was set, the
unit’s operation frequency is changed automatically.
• During DRY operation, the fan speed automatically runs at lower
speed for providing a comfortable breeze.
• ‘‘DRY’’ operation is not possible if the indoor temperature is 59 °F
or less.
Night Setback Mode is used for saving energy.
Press the NIGHT SETBACK button while operation.
The
mark appears in the display.
To release the night setback function, press the NIGHT SETBACK
button again.
Cooling ( ) operation
• Sometimes the indoor unit may not get to the set fan speed such as
LOW under cool operation at very low outdoor temperatures due to
the indoor unit being protected from ice or frost when combined with
the outdoor unit for Low Ambient Cooling models.
In Cooling and DRY Mode: ( and
)
When the night setback mode is selected, the air conditioner
automatically raises the temperature setting 2 °F when 30 minutes
have passed after the selection was made, and then another 2 °F
after another 30 minutes have passed, regardless of the indoor
temperature when night setback was selected. This enables you
to save energy without sacrificing comfort. This function is
convenient when gentle cooling is needed.
Power failure during operation
• In the event of power failure, the unit will stop. When the power is
resumed, the unit will restart automatically in approximately
5 minutes by the remote control unit.

‘‘DRY’’ ( ) Operation
How it works?
• Once the room temperature reaches the level that was set, the
unit’s operation frequency is changed automatically.
• During DRY operation, the fan speed automatically runs at lower
speed for providing a comfortable breeze.
• ‘‘DRY’’ operation is not possible if the indoor temperature is 59 °F
or less.
Night Setback Mode is used for saving energy.
Press the NIGHT SETBACK button while operation.
The
mark appears in the display.
To release the night setback function, press the NIGHT SETBACK
button again.
Cooling ( ) operation

LOW under cool operation at very low outdoor temperatures due to
the indoor unit being protected from ice or frost when combined with
the outdoor unit for Low Ambient Cooling models.
In Cooling and DRY Mode: ( and
)
When the night setback mode is selected, the air conditioner
automatically raises the temperature setting 2 °F when 30 minutes
have passed after the selection was made, and then another 2 °F
after another 30 minutes have passed, regardless of the indoor
temperature when night setback was selected. This enables you
to save energy without sacrificing comfort. This function is
convenient when gentle cooling is needed.
Power failure during operation
• In the event of power failure, the unit will stop. When the power is
resumed, the unit will restart automatically in approximately
5 minutes by the remote control unit.

part of your job to install or service the system so it operates
safely and efficiently.
When Installing…
…In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the
unit’s weight. It may be necessary to construct a strong
wood or metal frame to provide added support.
For safe installation and trouble-free operation, you
must:
…In a Room
G
Carefully read this instruction booklet before beginning.
Properly insulate any tubing run inside a room to prevent
“sweating” that can cause dripping and water damage to
walls and floors.
G
Follow each installation or repair step exactly as shown.
G
Observe all local, state, and national electrical codes.
G
Pay close attention to all warning and caution notices
When Connecting Refrigerant Tubing
given in this manual.
This symbol refers to a hazard
or unsafe practice which can
result in severe personal injury
or death.
• Do not add any refrigerant, air, or substance into the
refrigeration circuit other than the designated refrigerant
(R410A). Adding anything other than the specified refrig-
erant may cause the pressure to rise excessively in the
refrigeration circuit, rupturing the circuit and causing injury
or damage.
WARNING
This symbol refers to a hazard
or unsafe practice which can
result in personal injury or prod-
uct or property damage.
CAUTION
• Use all-new tubing and flare nuts to make the tubing con-
nections. Using any previous parts (from R22-based sys-
tems) may result in damage to the equipment, and may
lead to the refrigeration circuit rupturing, causing a seri-
ous accident.
If Necessary, Get Help
These instructions are all you need for most installation
sites and maintenance conditions. If you require help for a
special problem, contact our sales/service outlet or your
certified dealer for additional instructions.
• Apply refrigerant lubricant to the matching surfaces of
the flare and union tubes before connecting them, then
tighten the nut with a torque wrench for a leak-free
connection.
In Case of Improper Installation
The manufacturer shall in no way be responsible for improp-
er installation or maintenance service, including failure to
follow the instructions in this document.
• Check carefully for leaks before starting the test run.
When Servicing
SPECIAL PRECAUTIONS
• Turn the power OFF at the main power box (mains) before
opening the unit to check or repair electrical parts and
wiring.
WARNING
When Wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH. ONLY A
QUALIFIED, EXPERIENCED ELECTRICIAN
SHOULD ATTEMPT TO WIRE THIS SYSTEM.
• Keep your fingers and clothing away from any moving
parts.
• Clean up the site after you finish, remembering to check
that no metal scraps or bits of wiring have been left inside
the unit being serviced.
• Do not supply power to the unit until all wiring and tubing
are completed or reconnected and checked.
• Highly dangerous electrical voltages are used in this
system. Carefully refer to the wiring diagram and these
instructions when wiring. Improper connections and
inadequate grounding can cause accidental injury or
death.
CAUTION
• Ground the unit following local electrical codes.
• Connect all wiring tightly. Loose wiring may cause over-
heating at connection points and a possible fire hazard.
Others
• Ventilate any enclosed areas when installing or testing
the refrigeration system. Escaped refrigerant gas, on
contact with fire or heat, can produce dangerously
toxic gas.
When Transporting
Be careful when picking up and moving the indoor and out-
door units. Get a partner to help, and bend your knees when
lifting to reduce strain on your back. Sharp edges or thin alu-
minum fins on the air conditioner can cut your fingers.
• Confirm upon completing installation that no refrigerant
gas is leaking. If escaped gas comes in contact with a
stove, gas water heater, electric room heater or other heat
source, it can produce dangerously toxic gas.

2-2. Embedding the Tubing and Wiring
G Before beginning embedding installation work, consult
fully with agencies or offices related to the building’s
foundation, construction, electricity, and water.
G Wait to make connections to the embedded portion.
Each connection step is described later in this
manual.
G Securely cover the end of the embedded tubing to
prevent intrusion of dirt or moisture.
G If an embedded tube is to be left for a long time, fill
the tube with nitrogen and seal both ends securely.
If a tube is left open for an extended time, moisture in
the air inside the tubing may condense into water
droplets, and lead to water contamination of the refrig-
erant circuit.
G In order to prevent insulation breakdown and ground
faults, do not allow wiring ends to come in contact with
rainwater, or be subjected to condensation or dew.
G Apply sufficient thermal insulation to the refrigerant
tubing and drain pipes.

USING THE 1-HOUR OFF
TIMER
ADJUSTING THE AIRFLOW
DIRECTION
The vertical airflow can be adjusted by moving the flap with the
remote control unit. Do not move the flap with your hands. Confirm
that the remote control unit has been turned on. Use the FLAP
button to set either the sweep function or one of the six airflow
direction settings.
1. 1-Hour OFF Timer
This function causes the unit to operate for one hour and then
stop, regardless of whether the unit is on or off when this
button is pressed.
A. Sweep function
The flap starts moving
up and down to deliver
air over the sweep
range.
The
indicator in the display indicates that this function is
operating.
Setting procedure:
Regardless of whether the unit is operating or stopped, press the 1
HR. TIMER button.
B. Setting the airflow manually
appears in the display.
SWEEP
Referring to the above
Cancellation procedure:
Press the ON/OFF operation button to turn the unit off, wait for the
unit to stop operating, and then press the ON/OFF operation button
again.
The 1-Hour Timer function is now cancelled and the unit operates
normally.

operation.
NOTE
• If, while the 1-Hour Timer function is operating, the 1HR. TIMER
button is pressed once to cancel the function and then again, the
unit continues to operate for one hour from that point in time and
then stops.
• It is not possible to use the OFF Timer and 1-Hour OFF Timer
together. Whichever function is set last takes precedence. If the 1
HR. TIMER button is pressed while the TIMER OFF function
operates, the OFF Timer is cancelled and the unit will stop
operating one hour later.
NOTE
• The flap automatically closes when the unit is off.
• During the heating operation, the fan speed will be very low and the
flap will be in the horizontal position (position ) until the air being
blown out of the unit begins to warm. Once the air warms up, the
flap position and fan speed change to the settings specified with
the remote control unit.
CAUTION
2. Operation together with the daily ON/OFF
repeat timer
• Use the FLAP button on the remote control unit to adjust the
position of the flap. If you move the flap by hand, the flap
position according to the remote control unit and the actual
flap position may no longer match. If this should happen,
shut off the unit, wait for the flap to close, and then turn on
the unit again; the flap position will now be normal again.
• Do not have the flap pointed down during cooling operation.
Condensation may begin to form around the air vent and drip
down.
The 1-Hour OFF Timer setting is given priority over the DAILY ON/
OFF REPEAT setting.

Switching the room temperature sensor
Room temperature sensors are separately incorporated in both the indoor unit and the remote controller. Either sensor can
be used to sense the room temperature. The indoor unit sensor is usually used.
If you wish the remote controller to sense the room temperature, press the SENSOR button with a ballpoint pen or tool with
a small tip. (Refer to Fig. 9 on page 4 to locate the SENSOR button.)
I How to install the remote controller
IMPORTANT
• The remote controller is set to “Cool/Dry/Heat model” at
the time of shipment from the factory. If the purchased air
conditioner is a COOL/DRY model, follow the instructions
on the label and change the switch on the reverse side of
the remote controller unit to “Cool/Dry model”. (Fig. 1)
• The remote controller is also set to “Single” at the time of
shipment from the factory. For multiple use, set the
switch on the reverse side of the remote controller unit to
“Multi”. (Fig. 1)
