WARNING
WARNING
Important!
Please Read Before Starting
This air conditioning system meets strict safety and
operating standards. As the installer or service person, it
is an important part of your job to install or service the
system so it operates safely and efficiently.
For safe installation and trouble-free operation, you
must:
Carefully read this instruction booklet before beginning.
Follow each installation or repair step exactly as shown.
Observe all local, state, and national electrical codes.
Pay close attention to all warning and caution notices
given in this manual.
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.
In Case of Improper Installation
The manufacturer shall in no way be responsible for
improper installation or maintenance service, including
failure to follow the instructions in this document.
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.
Ground the unit following local electrical codes.
Connect all wiring tightly. Loose wiring may cause
overheating at connection points and a possible fire
hazard.
Install a protective leakage breaker depending on the
installation location (especially a damp or humid
location). If a leakage breaker is not installed, electric
shock can occur.
When Transporting
Be careful when picking up and moving the indoor and
outdoor units. Get a partner to help, and bend your knees
when lifting to reduce strain on your back. Sharp edges or
thin aluminum fins on the air conditioner can cut your
fingers.
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.
In a Room
Properly insulate any tubing run inside a room to prevent
"sweating" that can cause dripping and water damage to
walls and floors.
In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide a
solid, level foundation for the outdoor unit. This prevents
water damage and abnormal vibration.
In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a
metal frame. Provide a suitable air baffle.
In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher
than drifting snow. Provide snow vents.
When Connecting Refrigerant Tubing
Use the flare method for connecting tubing.
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.
Check carefully for leaks before starting the test run.
When Servicing
Turn the power off at the main power box (mains) before
opening the unit to check or repair electrical parts and
wiring.
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.
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.
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.

temperature and fan speed according to the conditions in the
room, in order to maintain a comfortable room environment.
SENSOR DRY operation
• DRY operation is as shown in the figure below.
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.
The compressor operation frequency varies.
The indoor fan operates with 1/f fluctuation.
The compressor operates at a low operating frequency.
The indoor fan operates with 1/f fluctuation.
• Monitoring operation takes place when the room temperature
is below 15 °C, or more than 3 °C below the set temperature.
• When the monitoring range is entered, the compressor stops,
and the indoor fan operates with 1/f fluctuation.

Overload prevention during heating
During HEAT operation, the temperature of the indoor heat
exchanger is used to control the frequency and lessen the load
on the compressor before the protective device is activated.
Cold-air prevention during heating
During heating, the fan speed is set to "LL" (very low) or stopped.
As the temperature of the indoor heat exchanger rises, the fan
speed is changed to the set speed.
Freeze prevention
During COOL or DRY operation, freezing is detected and
operation is stopped when the temperature of the indoor heat
exchanger matches the conditions below.
1.
Freeze-prevention operation is engaged when the
temperature of the indoor heat exchanger is below 6 °C.
2.

8. TROUBLESHOOTING
8-1. Precautions before Performing Inspection or Repair
NOTE
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.
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.
8-2. Method of Self-Diagnostics
Follow the procedure below to perform detailed trouble diagnostics.
< Clock display >
Test run mode
Self-diagnostics mode
PROCEDURE
Step 1: Press and hold the remote controller QUIET 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 QUIET and 1 HR TIMER buttons,
"oP-1" (test run) appears, blinking in the remote controller clock
display area.
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.
•  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.
After turning on power to the air conditioner, use the remote controller and
follow the steps below to execute self-diagnostics.

Connect a 5 k ohm resistor between inter-unit wirings 2 and 3. When the
voltage at both ends is measured, approximately 12 to 15V DC must
be output and the multimeter pointer must bounce once every 8
seconds.
Or instead of measuring the voltage, you can insert an LED jig and
check that the LED flickers once every 8 seconds.

ControlNo. Check items (unit operation)
Apply the rated voltage between outdoor
unit terminals L and N.
If there are no problems with the above, then check the indoor unit.
Turn the power OFF before performing short circuiting procedures.
Refer to the previous pages when performing system self-diagnostics.
So that the check can be made quickly, indicators blink at first communication after power ON.
Before performing the above checks, perform “TEST run” operation, and check that the rated voltage is output to terminals L and N
on the outdoor unit. If it is not output, there is a failure related to the indoor unit power.
1 The control panel LED (red) must illuminate.
Short-circuit the outdoor unit COM terminal
to the T-RUN terminal.
2 The compressor, fan motor, and 4-way valve must all turn on.

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.
[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).
(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.
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.
(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

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
1. Locations near broadcast stations where
there are strong electromagnetic waves
2. Locations near amateur radio (short wave)
stations
3. Locations near electronic sewing machines
and arc-welding machines
Correction
(The fundamental concept is to make the
system less susceptible to noise.)
- Insulate for noise or
distance from the noise source. -
1. Use shielded wires.
2. Move unit away from the noise source.
Trouble
Either of the following trouble may occur.
1. The unit may stop suddenly during
operation.
2. Indicator lamps may flicker.
(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
1. A television or radio is located near the
A/C and A/C wiring.
2. The antenna cable for a television or
radio is located close to the A/C and A/C
wiring.
3. Locations where television and radio
signals are weak.
Correction
1. Select a separate power source.
2. Keep the A/C and A/C wiring at least 1 meter
away from wireless devices and antenna cables.
3. Change the wireless device’s antenna to a high-
sensitivity antenna.
4. Change the antenna cable to a BS coaxial cable.
5. Use a noise filter (for the wireless device).
6. Use a signal booster.
Trouble
1. Noise appears in the television picture,
or the picture is distorted.
2. Static occurs in the radio sound.

• Depending on the room brightness, light from the LED CLEAN
lamp may reflect inside the air conditioner and be visible. This is
not a malfunction.
SPECIAL REMARKS
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 15 °C
or less.
Heating performance
• Because this air conditioner heats a room by drawing in the heat
of the outside air (heat pump system), the heating efficiency will
fall off when the outdoor temperature is very low. If sufficient heat
cannot be obtained with this air conditioner, use another heating
appliance together with it.
Defrosting
• When the outdoor temperature is low, frost or ice may form on
the heat exchanger coil, reducing heating performance. When
this happens, a microcomputer defrosting system operates. At
the same time, the fan on the indoor unit stops and the
OPERATION lamp lights red and orange alternately until
defrosting is completed. Heating operation restarts after several
minutes. (This interval will vary slightly depending upon the
outdoor temperature and the way in which frost forms.)
Cold draft prevention
• For several minutes after the start of heating operation, the
indoor fan runs at a lower speed until the indoor heat exchanger
coil has warmed up sufficiently. However, the fan may remain
stopped when the room temperature is low. This is because the
COLD DRAFT PREVENTION SYSTEM is in operation.
• In the event of power failure, the unit will stop. When the power is
resumed, the unit will restart automatically within 15 minutes by
the remote control unit.
Clicking sound is heard from the air conditioner
• In heating or cooling operation, any plastic parts may expand or
shrink due to a sudden temperature change. In this event, a
clicking sound may occur. This is normal, and the sound will
soon disappear.
• The remote control unit sends the setting condition to the air
conditioner regularly at five minute intervals.

TIPS FOR ENERGY SAVING
Do not
• Block the air intake and outlet of the unit. If they are
obstructed, the unit will not work well, and may be
damaged.
• Let direct sunlight into the room. Use sunshades, blinds or
curtains. If the walls and ceiling of the room are warmed by the
sun, it will take longer to cool the room.
Do
• Always try to keep the air filter clean. (Refer to “CARE AND
CLEANING”.) A clogged filter will impair the performance of the
unit.
• To prevent conditioned air from escaping, keep windows, doors
and any other openings closed.
ADJUSTING THE AIRFLOW
DIRECTION
1. Horizontal
The horizontal airflow can be adjusted by moving the vertical
vanes with your hands to the left or right.
When the humidity is high, the vertical vanes should be in the
front position during the cooling or dehumidifying operation.
If the vertical vanes are positioned all of the way to the right
or left, condensation may begin to form around the air vent
and drip down.
2. Vertical
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.
• 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.
• Use the FLAP button on the remote control to adjust the
position of the flap. If you move the flap by hand, the flap
position according to the remote control 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.

• Do not open the front panel while the LED CLEAN lamp on the
display is on.
• Depending on the room brightness, light from the LED CLEAN
lamp may reflect inside the air conditioner and be visible. This is
not a malfunction.
SPECIAL REMARKS
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 15 °C
or less.
Heating performance
• Because this air conditioner heats a room by drawing in the heat
of the outside air (heat pump system), the heating efficiency will
fall off when the outdoor temperature is very low. If sufficient heat
cannot be obtained with this air conditioner, use another heating
appliance together with it.
Defrosting
• When the outdoor temperature is low, frost or ice may form on
the heat exchanger coil, reducing heating performance. When
this happens, a microcomputer defrosting system operates. At
the same time, the fan on the indoor unit stops and the
OPERATION lamp lights red and orange alternately until
defrosting is completed. Heating operation restarts after several
minutes. (This interval will vary slightly depending upon the
outdoor temperature and the way in which frost forms.)
Cold draft prevention
• For several minutes after the start of heating operation, the
indoor fan runs at a lower speed until the indoor heat exchanger
coil has warmed up sufficiently. However, the fan may remain
stopped when the room temperature is low. This is because the
COLD DRAFT PREVENTION SYSTEM is in operation.
• Sometimes the indoor unit may not get to the set fan speed such
as LOW and QUIET under cool operation at very low outdoor
temperatures due to the indoor unit being protected from ice or
frost.
• In the event of power failure, the unit will stop. When the power is
resumed, the unit will restart automatically within 5 minutes or
15 minutes at M position of the S/M switch on AUTO mode by the
remote control unit.
Clicking sound is heard from the air conditioner
• In heating or cooling operation, any plastic parts may expand or
shrink due to a sudden temperature change. In this event, a
clicking sound may occur. This is normal, and the sound will
soon disappear.
• The remote control unit sends the setting condition to the air
conditioner regularly at five minute intervals.

TIPS FOR ENERGY SAVING
Do not
• Block the air intake and outlet of the unit. If they are
obstructed, the unit will not work well, and may be
damaged.
• Let direct sunlight into the room. Use sunshades, blinds or
curtains. If the walls and ceiling of the room are warmed by the
sun, it will take longer to cool the room.
Do
• Always try to keep the air filter clean. (Refer to “CARE AND
CLEANING”.) A clogged filter will impair the performance of the
unit.
• To prevent conditioned air from escaping, keep windows, doors
and any other openings closed.
ADJUSTING THE AIRFLOW
DIRECTION
1. Horizontal
The horizontal airflow can be adjusted by moving the vertical
vanes with your hands to the left or right.
When the humidity is high, the vertical vanes should be in the
front position during the cooling or dehumidifying operation.
If the vertical vanes are positioned all of the way to the right
or left, condensation may begin to form around the air vent
and drip down.
2. Vertical
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.
• 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.
• Use the FLAP button on the remote control to adjust the
position of the flap. If you move the flap by hand, the flap
position according to the remote control 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.

IMPORTANT!
Please Read Before Starting
This air conditioning system meets strict safety and oper-
ating standards. As the installer or service person, it is an
important part of your job to install or service the system
so it operates safely and efficiently.
For safe installation and trouble-free operation, you
must:
GCarefully read this instruction booklet before beginning.
GFollow each installation or repair step exactly as
shown.
GObserve all local, state, and national electrical codes.
GPay close attention to all warning and caution notices
given in this manual.
This symbol refers to a hazard
or unsafe practice which can
result in severe personal injury
or death.
This symbol refers to a hazard
or unsafe practice which can
result in personal injury or
product or property damage.
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.
In Case of Improper Installation
The manufacturer shall in no way be responsible for
improper installation or maintenance service, including
failure to follow the instructions in this document.
SPECIAL PRECAUTIONS
When Wiring
ELECTRICAL SHOCK CAN CAUSE
SEVERE PERSONAL INJURY OR DEATH.
ONLY A QUALIFIED, EXPERIENCED
ELECTRICIAN SHOULD ATTEMPT TO
WIRE THIS SYSTEM.
• Do not supply power to the unit until all wiring and tub-
ing 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.
• Ground the unit following local electrical codes.
• Connect all wiring tightly. Loose wiring may cause
overheating at connection points and a possible fire
hazard.
• Install a protective leakage breaker depending on the
installation location (especially a damp or humid loca-
tion). If a leakage breaker is not installed, electric
shock can occur.
When Transporting
Be careful when picking up and moving the indoor and
outdoor units. Get a partner to help, and bend your knees
when lifting to reduce strain on your back. Sharp edges or
thin aluminum fins on the air conditioner can cut your fin-
gers.
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.
…In a Room
Properly insulate any tubing run inside a room to prevent
“sweating” that can cause dripping and water damage to
walls and floors.
…In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide
a solid, level foundation for the outdoor unit. This pre-
vents water damage and abnormal vibration.
When Connecting Refrigerant Tubing
• Do not add any refrigerant, air, or substance into the
refrigeration circuit other than the designated refriger-
ant (R410A). Adding anything other than the specified
refrigerant may cause the pressure to rise excessively
in the refrigeration circuit, rupturing the circuit and
causing injury or damage.
• Use all-new tubing and flare nuts to make the tubing
connections. Using any previous parts (from R22-
based systems) may result in damage to the equip-
ment, and may lead to the refrigeration circuit ruptur-
ing, causing a serious accident.
• 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.
• Check carefully for leaks before starting the test run.
When Servicing
• Turn the power OFF at the main power box (mains)
before opening the unit to check or repair electrical
parts and wiring.
• 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.
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.
• 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.

as shown on its nameplate, then carry out the
wiring closely following the wiring diagram.
(2) Provide a power outlet to be used exclusively for
each unit, with a power supply disconnect and cir-
cuit breaker for overcurrent protection provided in
the exclusive line.
(3) To prevent possible hazard due to insulation fail-
ure, the unit must be grounded.
(4) Each wiring connection must be done tightly and
in accordance with the wiring system diagram.
Wrong wiring may cause the unit to misoperate or
become damaged.
(5) Do not allow wiring to touch the refrigerant tubing,

IMPORTANT!
Please Read Before Starting
This air conditioning system meets strict safety and oper-
ating standards. As the installer or service person, it is an
important part of your job to install or service the system
so it operates safely and efficiently.
For safe installation and trouble-free operation, you
must:
GCarefully read this instruction booklet before beginning.
GFollow each installation or repair step exactly as
shown.
GObserve all local, state, and national electrical codes.
GPay close attention to all warning and caution notices
given in this manual.
This symbol refers to a hazard
or unsafe practice which can
result in severe personal injury
or death.
This symbol refers to a hazard
or unsafe practice which can
result in personal injury or
product or property damage.
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.
In Case of Improper Installation
The manufacturer shall in no way be responsible for
improper installation or maintenance service, including
failure to follow the instructions in this document.
SPECIAL PRECAUTIONS
When Wiring
ELECTRICAL SHOCK CAN CAUSE
SEVERE PERSONAL INJURY OR DEATH.
ONLY A QUALIFIED, EXPERIENCED
ELECTRICIAN SHOULD ATTEMPT TO
WIRE THIS SYSTEM.
• Do not supply power to the unit until all wiring and tub-
ing 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.
• Ground the unit following local electrical codes.
• Connect all wiring tightly. Loose wiring may cause
overheating at connection points and a possible fire
hazard.
• Install a protective leakage breaker/fuse link depend-
ing on the installation location (especially a damp or
humid location). If a leakage breaker/fuse link is not
installed, electric shock can occur.
When Transporting
Be careful when picking up and moving the indoor and
outdoor units. Get a partner to help, and bend your knees
when lifting to reduce strain on your back. Sharp edges or
thin aluminum fins on the air conditioner can cut your fin-
gers.
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.
…In a Room
Properly insulate any tubing run inside a room to prevent
“sweating” that can cause dripping and water damage to
walls and floors.
…In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide
a solid, level foundation for the outdoor unit. This pre-
vents water damage and abnormal vibration.
When Connecting Refrigerant Tubing
• Do not add any refrigerant, air, or substance into the
refrigeration circuit other than the designated refriger-
ant (R410A). Adding anything other than the specified
refrigerant may cause the pressure to rise excessively
in the refrigeration circuit, rupturing the circuit and
causing injury or damage.
• Use all-new tubing and flare nuts to make the tubing
connections. Using any previous parts (from R22-
based systems) may result in damage to the equip-
ment, and may lead to the refrigeration circuit ruptur-
ing, causing a serious accident.
• 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.
• Check carefully for leaks before starting the test run.
When Servicing
• Turn the power OFF at the main power box (mains)
before opening the unit to check or repair electrical
parts and wiring.
• 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.
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.
• 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.

3-3. Install the Rear Panel on the Wall
Be sure to confirm that the wall is strong enough to
suspend the unit.
See either Item a) or b) below depending on the wall
type.
a) If Wooden Wall
(1) Attach the rear panel to the wall with the 8 screws
provided. (Fig. 13a, 13b or 13c)
If you are not able to line up the holes in the rear
panel with the beam locations marked on the wall,
use rawl plugs or toggle bolts to go through the
holes on the panel or drill 5 mm dia. holes in the
panel over the stud locations and then mount the
rear panel.
(2) Double check with a carpenter’s level or tape mea-
sure that the panel is level. This is important to
install the unit properly. (Fig. 14)
(3) Make sure the panel is flush against the wall. Any
space between the wall and unit will cause noise
and vibration.
b) If Block, Brick, Concrete or Similar Type Wall
Make 4.8 mm dia. holes in the wall. Insert rawl plugs
for appropriate mounting screws. (Fig. 15)

The remote control unit can be operated from either a
non-fixed position or a wall-mounted position.
To ensure that the air conditioner operates correctly,
do not install the remote control unit in the following
places:
GIn direct sunlight
GBehind a curtain or other place where it is covered
GMore than 8 m away from the air conditioner
GIn the path of the air conditioner’s airstream
GWhere it may become extremely hot or cold
GWhere it may be subject to electrical or magnetic
interference
GWhere there is an obstacle between the remote
control unit and the air conditioner (since a check
signal is sent from the remote control unit every 5
minutes)
6-1. Mounting on a Wall
