(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.
NOTE
(CLxx models only)
The Sensor Dry operation during the Low Ambient Cooling
Mode (outside air temperature:59°F(15°C) or lower) is as
follows.
DRY A
and
DRY B
The compressor operates a cycle of 3 minutes ON and 6
minutes OFF repeatedly.
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.
32
HIGH POWER
NIGHT SETBACK
This function acts to raise the power but keeps the AC system in
the same operating mode.
ꢀ 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.
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.)
ꢀ HIGH POWER operation from remote controller
COOL and DRY modes
ꢀ The unit operates at maximum output for 30 minutes,
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.

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 43°F(6°C).
2.ꢀ Restart after freeze-prevention operation occurs when the
temperature of the indoor heat exchanger reaches 46°F(8°C)
or above.

*ꢀ When the temperature drops to below 36°F(2°C) (continuously
for 2 minutes or longer), the compressor stops.
Once the freeze condition is detected, the air conditioner will
work less than the maximum frequency until it is turned off.
NOTE
(CLxx models only)
The Freeze Prevention Control during the Low Ambient Cooling
Mode (outside air temperature:59°F(15°C) or lower) is as follows.
The compressor stops when the temperature of indoor heat
exchanger becomes less than 36°F(2°C).
The compressor restarts when the temperature of indoor heat
exchanger becomes 46°F(8°C) or higher.

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
Follow the procedure below to perform detailed trouble diagnostics.
< Clock display >
Test run mode
NOTE
Self-diagnostics mode
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.
ION
button
Step 1: Press and hold the remote controller ION button and 1 HR TIMER
button. At the same time, press the ACL (reset) button. Use a
pointed object such as the tip of a pen to press the ACL button.
1HR.
ꢀ
When this has been done, "oP-1" (test run) appears, blinking, in
the remote controller clock display area.
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
• ꢀThe 3 lamps remain OFF if no trouble has occurred.

8-3. Checking the Indoor and Outdoor Units
(1) Checking the indoor unit
No.
Control
Check items (unit operation)
• The rated voltage must be present between inter-unit wirings 1 and 2.
1
Use the remote controller to operate the
unit in "TEST run" mode. To determine
whether the mode is currently in
"TEST run" mode, check the 4 indicator
lamps on the unit. If all 4 are blinking,
the current mode is "TEST run."
•
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.
If there are no problems with the above, then check the outdoor unit.
For the "Test run" procedure, refer to "4. How to Test Run the Air Conditioner" on Appendix B.
(2) Checking the outdoor unit
No.
Control
Check items (unit operation)
1
Apply the rated voltage between outdoor
unit terminals L1 and L2.
• The control panel LED (red) must illuminate.
2
Short-circuit the outdoor unit COM terminal
to the T-RUN terminal.
• The compressor and fan motor must all turn on.
If there are no problems with the above, then check the indoor unit.

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 230 V or more
DC 14 V or more
(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
Fluctuation between DC 1.7 to 6.1 V
(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)

[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.

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.
Cooling ( ) 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 when combined with the outdoor
unit for Low Ambient Cooling models.
•
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
Clicking sound is heard from
the air conditioner
•
•
In cooling operation, any plastic parts may 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.

“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
• 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
or death.
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.
Others
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.
• 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
• 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.
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.

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.
