SAFETY PRECAUTIONS
Warning
Before performing an overhaul, disconnect the power plug or power cable from the unit.
Performing the work with the power supplied to the unit, may cause an electric shock.
When repair work or circuit inspection that requires power supply for the air conditioner, is to be performed,
do not touch the charging section.
Doing so may cause an electric shock.
For the step-up capacitor attached to the electric section, perform the repair work after sufficiently discharging it.
Insufficient capacitor discharge may cause an electric shock.
Do not perform repair work on the electric sections with wet hands.
Doing so may cause an electric shock.
Do not start or stop the air conditioner by means of connecting or disconnecting the power plug.
Doing so may cause an electric shock or fire.
When conducting repair work only use components included in the parts list for the corresponding unit and perform
the work with the appropriate tools.
Incorrect or poor repair work may cause an electric shock or fire.
Never modify the unit.
Doing so may cause an electric shock or fire.
Perform all electric work according to local applicable regulations related to electrical equipment or interior wiring
regulation and make sure to use the exclusive circuit.
Insufficient capacity to the electric circuit or defective arrangement results may cause an electric shock or fire.
Make sure to replace any power cable or lead wire showing any signs of scratch or deterioration.
Failure to do so may cause an electric shock, overheating or fire.
Make sure that there is no dust on or slack in the power plug and insert fully into the socket.
Dust or incomplete connections may cause an electric shock or fire.
Do not damage or process the power cord, as it may cause an electric shock or fire.
For the wiring between the indoor unit and outdoor unit, securely fix the specified cable onto the terminal plate.
Poorly fixed wiring may cause a heat or fire.
After connecting the wiring between the indoor unit and outdoor unit, attach the terminal cover securely.
Incomplete attachment of the terminal cover may cause overheating or fire.

Warning
If refrigerant gas blows off during the work, do not touch the refrigerant gas as it may cause frostbite.
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."
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.
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.
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.

7-2. Protective Functions
This function prevents the circuit breaker or fuse from operating
to open the circuit. This function works when electrical current
has increased due to an increase in the cooling load,
or to a decrease in the power supply voltage. In these cases,
operation frequency is reduced or operation is interrupted auto-
matically to control the electrical current for operation.
When the cause of the increase in electrical current is rectified,
the system will resume operation in the original mode.

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
Deletion of self-diagnostics
report 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 twice to change the display
from "oP-1" to "oP-2" and "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.

motor to the outdoor unit controller.)
[Trouble symptom 4]Fan motor rotation speed does not change during outdoor unit operation.
[Trouble symptom 5]Fan motor rotation speed varies excessively during outdoor unit operation.
(Remedy for symptom 3 to 5)
It is not possible to identify whether the trouble is outdoor unit controller trouble or motor trouble.
Therefore, first replace the outdoor 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 outdoor controller connector for (3) in the table
below, the DC motor will trip and voltage output will stop approximately 10 seconds after
operation is started. For this reason, to measure the voltage again, first turn OFF the outdoor
unit power, then, measure the voltage in Test Run mode.

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.

The insulation is in good condition if the resistance
exceeds 1M ohm.
9-1-1. Power Supply Cord
Clamp the grounding wire of power cord with the lead
clip of the insulation resistance tester and measure the
resistance by placing a probe on either of the two
power wires. (Fig. 1)
Then also measure the resistance between the
grounding and other power terminals. (Fig. 1)
9-1-2. Indoor Unit
Clamp an aluminum plate fin or copper tube with the
lead clip of the insulation resistance tester and
measure the resistance by placing a probe on each
terminal screw on the terminal plate. (Fig. 2)
Note that the ground line terminal should be skipped
for the check.
9-1-3. Outdoor Unit
Clamp a metallic part of the unit with the lead clip of
the insulation resistance tester and measure the
resistance by placing a probe on each terminal screw
where power supply lines are connected on the
terminal plate. (Fig. 2)
9-1-4.Measurement of Insulation
Resistance for Electrical Parts
Disconnect the lead wires of the desired electric part
from terminal plate, capacitor, etc. Similarly disconnect
the connector. Then measure the insulation resistance.
(Figs. 3 and 4)

10. REFRIGERANT R410A:
SPECIAL PRECAUTIONS WHEN SERVICING UNIT
10-1. Characteristics of New Refrigerant R410A
10-1-1. What is New Refrigerant R410A?
R410A is a new refrigerant that contains two types of pseudo-non-azeotropic refrigerant mixture. Its
refrigeration capacity and energy efficiency are about the same level as the conventional refrigerant, R22.
10-1-2. Components (mixing proportions)
HFC32 (50%) / HFC125 (50%)
10-1-3. Characteristics
Less toxic, more chemically stable refrigerant
The composition of refrigerant R410A changes whether it is in a gaseous phase or liquid phase. Thus, when
there is a refrigerant leak the basic performance of the air conditioner may be degraded because of a change in
composition of the remaining refrigerant. Therefore, do not add new refrigerant. Instead, recover the
remaining refrigerant with the refrigerant recovery unit. Then, after evacuation, totally recharge the specified
amount of refrigerant with the new refrigerant at its normal mixed composition state (in liquid phase).
When refrigerant R410A is used, the composition will differ depending on whether it is in gaseous or liquid
phase, and the basic performance of the air conditioner will be degraded if it is charged while the refrigerant is in
gaseous state. Thus, always charge the refrigerant while it is in liquid phase.
Ether-type oil is used for compressor oil for R410A-type units, which is different
from the mineral oil used for R22. Thus more attention to moisture prevention and
faster replacement work compared with conventional models are required.
CAUTION
48
Tubing precautions
Refrigerant R410A is more easily affected by dust or moisture compared with R22, thus be sure to temporarily
cover the ends of the tubing with caps or tape prior to installation.
Never use 0.0276" (0.7 mm)-thick copper tubing or tubing which is less than 0.0315" (0.8 mm) in thickness, since
air conditioners with R410A are subject to higher pressure than those using R22 and R407C.
No addition of compressor oil for R410A
No additional charge of compressor oil is permitted.
No use of refrigerant other than R410A
Never use a refrigerant other than R410A.
If refrigerant R410A is exposed to fire
Through welding, etc., toxic gas may be released when R410A refrigerant is exposed to fire. Therefore, be sure
to provide ample ventilation during installation work.
Caution in case of R410A leak
Check for possible leak points with the special leak detector for R410A. If a leak occurs inside the room,
immediately provide thorough ventilation.

Tools which can be com-
monly used for R22,
R407C, and R410A
CAUTION The above tools specifically for R410A must not be used for R22 and R407C.
Doing so will cause malfunction of the unit.
For the above vacuum pump (*1, *2) and vacuum pump adapter (*3), those for
R22-type units can be used for R410A-type. However, they must be used
exclusively for R410A and never alternately with R22 and R407C.
For details on tubing installation procedures, refer to the installation manuals attached to the indoor
unit and outdoor unit.
To prevent other refrigerants (R22, R407C) from being mistakenly charged to this unit, shape and external
diameter of the service port screw has been altered.
<External diameter of service port> R410A : 5/16"
R22, R407C : 1/4"
10-4. Tubing Installation Procedures
When the tubes are connected, always apply HAB oil on the flare portions to improve the sealing of tubing.
The following is the HAB oil generally used:
Esso: ZERICE S32
NOTE

10-5. In Case of Compressor Malfunction
CAUTION Should the compressor malfunction, be sure to make the switch to a replacement
compressor as quickly as possible.
Use only the tools indicated exclusively for R410A. See "10-3. Tools
Specifically for R410A."
10-5-1. Procedure for Replacing Compressor
(1) Recovering refrigerant
Any remaining refrigerant inside the unit should not be
released to the atmosphere, but recovered using the
refrigerant recovery unit for R410A.
Do not reuse the recovered refrigerant, since it will contain
impurities.
(2) Replacing Compressor
Soon after removing seals of both discharge and suction
tubes of the new compressor, replace it quickly.
(3) Checking for sealing
Use nitrogen gas for the pressurized gas, and never use a
refrigerant other than R410A. Also do not use oxygen or
any flammable gas.
(4) Evacuation
Use a solenoid valve-installed vacuum pump so that
even if power is cut off in the middle of evacuation of air
due to a power interruption, the valve will prevent the
pump oil from flowing back.
The equipment may be damaged if moisture remains in
the tubing, thus carry out the evacuation thoroughly.
When using a vacuum pump with exhaust air volume more
than 0.883 cu.ft./min. and ultimate vacuum pressure rate
of 50 micron Hg.

CAUTION Never charge a large amount
of liquid refrigerant at once to
the unit. This may cause
damage to the compressor.
CAUTION To prevent the composition
of R410A from changing,
never bleed the refrigerant
gas into the atmosphere
while transferring the
refrigerant. (Fig. 3)
(5) Recharging
Be sure to charge the specified amount of
refrigerant in liquid state using the service port
of the wide tube service valve. The proper
amount is listed on the unit's nameplate.
When the entire amount cannot be charged all at
once, charge gradually while operating the unit in
Cooling Operation.
When charging with a refrigerant cylinder, use an
electronic scale for charging refrigerant. In this
case, if the volume of refrigerant in the cylinder
becomes less than 20% of the fully-charged
amount, the composition of the refrigerant starts
to change. Thus, do not use the refrigerant if
the amount in the charging cylinder is less
than 20%.
Also, charge the minimum necessary amount to
the charging cylinder before using it to charge
the air conditioning unit.
Example:
In case of charging refrigerant to a unit requiring
1.68 lb. (0.76 Kg) using a capacity of a 22 lb. (10
Kg) cylinder, the minimum necessary amount for
the cylinder is:
1.68 + 22 0.20 = 6.08 lb.
(0.76 + 10 0.20 = 2.76 Kg)
For the remaining refrigerant, refer to the
instructions of the refrigerant manufacturer.
If using a charging cylinder, transfer the specified
amount of liquid refrigerant from the refrigerant
cylinder to the charging cylinder.
Prepare an evacuated charging cylinder
beforehand.
Do not use the refrigerant if the amount in the
charging cylinder is less than 20%.

10-6. In Case Refrigerant is Leaking
CAUTION Never attempt to charge additional refrigerant when refrigerant has been leaking
from the unit. Follow the procedure described below to locate points of leaks and
carry out repairs, then recharge the refrigerant.
(1) Detecting Leaks
Use the detector for R410A to locate refrigerant leak
points.
(2) Recovering refrigerant
Never release the gas to the atmosphere; recover
residual refrigerant using the refrigerant recovery unit for
R410A, instead.
Do not reuse the recovered refrigerant because its
composition will have been altered.
(3) Welding leaking points
Confirm again that no residual refrigerant exists in the unit
before starting welding.
Weld securely using flux and wax for R410A.
Prevent oxide film from forming inside the tubes utilizing
substitution with nitrogen (N2) in the refrigerant circuit of
the unit. Leave ends of tubes open during welding.
(4) Checking for sealing
Use nitrogen gas for the pressurized gas, and never use
a refrigerant other than R410A. Also do not use oxygen or
any flammable gas.
(5) Evacuation
Use a solenoid valve-installed vacuum pump so that
even if power is cut off in the middle of evacuation of air
due to a power interruption, the valve will prevent the
pump oil from flowing back.
The equipment may be damaged if moisture remains in
the tubing, thus carry out the evacuation thoroughly.

10-7. Charging Additional Refrigerant
10-7-1. When Tubes are Extended
Observe the proper amount of refrigerant as stated in this service manual or the installation manual that came
with the indoor unit. Charge additional refrigerant in liquid state only.
10-8. Retro-Fitting Existing Systems
10-8-1. Use of Existing Units
Never use new refrigerant R410A for existing units which use R22. This will cause the air conditioner to
operate improperly and may result in a hazardous condition.
10-8-2. Use of Existing Tubing
If replacing an older unit that used refrigerant R22 with a R410A unit, do not use its existing tubing. Instead,
completely new tubing must be used.
CAUTION Never charge additional refrigerant if refrigerant is leaking from the unit. Follow
instructions given in "10-6. In Case Refrigerant is Leaking" and completely carry
out repairs. Only then should you recharge the refrigerant.

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 59 °F
or less.
• 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.
• 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.
If the remote control unit is on and left in a location where the unit
can receive a signal, then the unit will automatically restart in
approximately 5 minutes of power being restored.
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.

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.
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 prod-
uct 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 improp-
er 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 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 over-
heating at connection points and a possible fire hazard.
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.
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
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.

In regions with snow and strong wind, the following
problems may occur when the outdoor unit is not
provided with a platform and ducting:
a) The outdoor fan may not run and damage to the
unit may occur.
b) There may be no air flow.
c) The tubing may freeze and burst.
d) The condenser pressure may drop because of
strong wind, and the indoor unit may freeze.
2-2-2. Precautions for Installation in a Snowy Area
(1) The platform should be higher than the maximum
snow depth. (Fig. 5g)
(2) The 2 anchoring feet of the outdoor unit should
be used for the platform, and the platform should
be installed beneath the air intake side of outdoor
unit.
(3) The platform foundation must be firm and the unit
must be secured with anchor bolts.

the stationary tabs from the frame. (Fig. 7a)
(3) Remove the rear panel by grasping the sections shown
in Fig. 7b and pulling it in the direction shown by the
arrow.
Tubing can be extended in 6 directions as shown in Fig. 8.
Select the direction you need providing the shortest run to
the outside unit.
●When left tubing is to be done, switch the drain hose and
drain cap. (For details, refer to “Switching drain hose and
drain cap” on page 20.)
3-2. Make a Hole
(1) Place the rear panel from the indoor unit on the wall at
the location selected. Make sure the panel is horizontal,
using a carpenter’s level or tape measure to measure
down from the ceiling. Wait until after cutting the hole
before attaching the rear panel to the wall.
(2) Determine which side of the unit you should make the
hole for tubing and wiring. (Fig. 9)
In the case of left-rear tubing, use the measurement points
6-7/32" (158 mm) from the marked position on the rear
panel for precise placement of the hose outlet. (Fig. 9)
(3) Before making the hole, check carefully that no studs or
pipes are directly run behind the spot to be cut.
The above precautions are also applicable if tubing
goes through the wall in any other location.

3-3. Install the Rear Panel on the Wall
Be sure to confirm that the wall is strong enough to sus-
pend the unit.
There are a number of screw holes on the rear panel.
Using the 8 screw holes with mark is recommended
to attach the rear panel securely to the wall.
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. 13)
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 3/16" (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

remove the cover. (Fig. 17a)
(5) Remove the lower flap by disengaging 4 pins of the
lower flap in order. (Figs. 17b and 17c)
(The flap is so flexible that it can be easily removed.)
(6) Lift up the grille in the direction shown by the arrow
and pull the grille towards you to remove it. (Fig. 17d)
How to replace the grille
(1) While aligning the top edge of the grille with the
frame, move the grille horizontally and insert the top
and bottom into the frame.
(2) Press the grille firmly with your hand to ensure no gap
exists between the frame and grille.
(3) Tighten the 6 screws. And fix the removed covers in
place.
(4) Grasp the sections near the front panel arms on both
sides, and hold the front panel so that it is nearly hori-
zontal. Push the arm shafts towards the outside so
that they come into contact with the top of the inden-
tations on the right and left sides of the air condition-
er. Then push firmly until the arm shafts click into
place. (Fig. 18)
(5) Remount the lower flap.
(In remounting the flap, it cannot be turned end for
end because the right and left pins of the flap differ in
form. (Fig. 17c))
(6) Insert the top of the anti-mold filter, and then secure
the bottom of the filter with the protrusions on the unit.
(7) When closing the front panel, push the central part of

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 hazards due to insulation failure,
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,
compressor, or any moving parts of the fan.
(6) Unauthorized changes in the internal wiring can be
very dangerous. The manufacturer will accept no
responsibility for any damage or misoperation that
occurs as a result of such unauthorized changes.

4. How to Install the Outdoor Unit
First refer to Section 2. Installation Site Selection.
4-1. Wiring Instructions for the Outdoor Unit
Regulations on wire size differ from locality to locality. For
field wiring requirements, please refer to your local elec-
trical codes. Make sure that the installation fully complies
with all local and national regulations.
(1) Remove the 3 screws from the inspection panel.
(Fig. 46a)
Remove the inspection panel by sliding it downward
and pulling it toward you. (Fig. 46b)
(2) Connect the inter-unit and power supply line accord-
ing to the wiring system diagram on the inspection
panel. (Fig. 46c)
(3) When connections are completed, check that all
connections are correct as shown in the wiring sys-
tem diagram.
(4) Be sure to ground the unit according to your local
codes.
4-2. Routing the Tubing and Wiring
●The tubing and wiring can be extended out in 3 direc-
tions: front, rear, and right. Use a nipper or similar
tool to cut out the knockout holes for the inter-unit
control wiring outlet, power wiring outlet, and tubing
outlet from the appropriate covers A and B. (Fig. 46d)
●Route the tubing so that it does not contact the
compressor, panel, or other parts inside the unit.
Increased noise will result if the tubing contacts
these parts.
●When routing the tubing, use a tube bender to
bend the tubes.

5. Refrigerant Tubing
5-1. Use of the Flaring Method
Many of the conventional split system air conditioners
employ the flaring method to connect refrigerant tubes
which run between indoor and outdoor units. In this
method, the copper tubes are flared at each end and
connected with flare nuts.
5-2. Flaring Procedure with a Flare Tool
(1) Cut the copper tube to the required length with a
tube cutter. It is recommended to cut approx. 12" to
20" (30 to 50 cm) longer than the tubing length you
estimate.
(2) Remove burrs at the end of the copper tube with a
tube reamer or file. This process is important and
should be done carefully to make a good flare.
(Fig. 47)
When reaming, hold the tube end downward and be
sure that no copper scraps fall into the tube. (Fig. 48)
(3) Remove the flare nut from the unit and be sure to
mount it on the copper tube.
(4) Make a flare at the end of copper tube with a flare
tool.*(Figs. 49a and 49b)
(*Use “RIDGID” or equivalent.)
A good flare should have the following characteristics:
●inside surface is glossy and smooth.
●edge is smooth.
●tapered sides are of uniform length.
5-3. Caution before Connecting Tubes Tightly
a) Be sure to apply a sealing cap or water-proof tape
to prevent dust or water from getting into the tubes
before they are used.
b) Be sure to apply refrigerant lubricant to the match-
ing surfaces of the flare and union before connect-
ing them together. This is effective for reducing gas
leaks. (Fig. 50)
c) For proper connection, align the union tube and
flare tube straight with each other, then screw in the
flare nut lightly at first to obtain a smooth match.

5-4. Connecting Tubing between Indoor and
Outdoor Units
a) Tightly connect the indoor side refrigerant tubing exten-
ded from the wall with the outdoor side tubing. (Fig. 52)
b) To fasten the flare nuts, apply specified torque as:
Table 6
5-5. Insulation of Refrigerant Tubing
To prevent heat loss and wet floors due to dripping of con-
densation, both tubes must be well insulated with a
proper insulation material. (Fig. 53)
The thickness of the insulation should be a minimum 5/16"
(8 mm). (Fig. 54)
5-6. Taping the Tubes
(1) At this time, the 2 refrigerant tubes (and electrical wire
if local codes permit) should be taped together with
armoring tape. The drain hose may also be included
and taped together as 1 bundle with the tubing.
(2) Wrap the armoring tape from the bottom of the outdoor
unit to the top of the tubing where it enters the wall. As
you wrap the tubing, overlap half of each previous tape
turn. (Fig. 55)
(3) Clamp the tubing bundle to wall, using 1 clamp approx.
every 47" (120 cm).
Do not wind the armoring tape too tightly, since this will
decrease the heat insulation effect. Also, be sure the con-
densation drain hose splits away from the bundle and drips
clear of the unit and the tubing.
5-7. Finishing the Installation
After finishing insulating and taping over the tubing, use
sealing putty to seal off the hole in the wall to prevent rain
and draft from entering. (Fig. 56)

6. Air Purging
Air and moisture remaining in the refrigerant system
have undesirable effects as indicated below. Therefore,
they must be purged completely.
●pressure in the system rises
●operating current rises
●cooling (or heating) efficiency drops
●moisture in the air may freeze and block capillary tubing
●water may lead to corrosion of parts in the refrigerant
system
■Air Purging with a Vacuum Pump (for Test Run)
(1) Check that each tube (both narrow and wide tubes)
between the indoor and outdoor units have been
properly connected and all wiring for the test run
has been completed. Note that both narrow and
wide tube service valves on the outdoor unit are
kept closed at this stage.
(2) Using an adjustable wrench or box wrench, remove
the valve caps from the service valve on both nar-
row and wide tubes.
(3) Connect a vacuum pump and a manifold valve (with
pressure gauges) to the service port on the wide
tube service valve. (Fig. 57)
(4) With the “Lo” knob of the manifold valve open, run
the vacuum pump. The operation time for the vacu-
um pump varies with tubing length and the capacity
of the pump. The following table shows the amount
of time for evacuation:

CAUTION
Be sure to use a manifold valve
for air purging. If it is not avail-
able, use a stop valve (field sup-
ply) for this purpose. The “Hi”
knob of the manifold valve must
always be kept closed.
The required time in Table 7 is calculated based on the
assumption that the ideal (or target) vacuum condition
is around 10 mmHg abs.
NOTE

100 liter/h vacuum pump is used
If tubing length is If tubing length is
less than 33 ft. (10 m) more than 33 ft. (10 m)
10 min. or more 15 min. or more
CAUTION
The service port on the wide tube
service valve uses a Schrader core
valve to access the refrigerant sys-
tem. The valve core is similar to
those used in automobile tires.
Therefore, be sure to use a vacuum
hose connector which has a push-
pin inside.
To prevent other refrigerants from being mistakenly
charged to units which use R410A, the size of the
charge port on the service valve is different from the
one for other refrigerant types. For servicing such as
recharging, the specified charging hose, manifold and
vacuum pump adapter (with reverse flow prevention)
for R410A must be used.

(5) With the vacuum pump still running, close the “Lo”
knob of the manifold valve. Then stop the vacuum
pump.
(6) With the hex wrench, turn the valve stem on the nar-
row tube service valve counter-clockwise by 90
degrees (1/4 turn) for 10 seconds, and then turn the
stem clockwise to close it again. (Fig. 58)
(7) Leak test all joints at the tubing (both indoor and out-
doors) with soapy water. Bubbles indicate a leak. Tight-
en the joint more when leaks, then check if there is no
leak. Be sure to wipe off the soap with a clean cloth.
(8) With the hex wrench, turn the wide tube service
valve stem counter-clockwise to fully open the valve.
(9) Turn the narrow tube service valve stem counter-
clockwise to fully open the valve.
(10) Loosen the vacuum hose connected to the wide
tube service port slightly to release the pressure.
Then, remove the hose.
(11) Fasten the valve cap on the wide tube service port
securely with an adjustable wrench or box wrench.
Next, mount the valve cap on the service valve and
tighten it to 170 lbs·in (200 kgf·cm) with a torque
wrench. This process is very important to prevent
gas from leaking from the system.
(12) Test run the air conditioner. (See next page.)
(13) While the air conditioner is running, apply liquid
soap to check for any gas leaks around the service
valves or caps.
(14) If there is no leakage, stop the air conditioner.
(15) Wipe off the soap on the tubing.
This completes air purging with a vacuum pump and the
air conditioner is ready for actual operation.
CAUTION
Be sure to completely insert
the hex wrench before
attempting to turn the valve.

CAUTION
This may cause the refriger-
ant gas to leak. In order to
avoid this, take off the hose
quickly.

How to Test Run the Air Conditioner
After turning on the power of the air conditioner, use the
remote controller and follow the steps below to conduct the
test run.
(1) Set the remote controller in Test Run mode.
(Fig. 59a)
a) Press and hold the QUIET button and the 1HR.
TIMER button.
b) Then press and hold the ACL (Reset) button with a
pointed object such as the tip of a pen. After 5 sec-
onds, release the ACL button first.
c) Then release the QUIET and 1HR. TIMER buttons.
d) appears and “oP-1” blinks in the remote controller
clock display area. (Fig. 59b)
(2) Start Cooling mode test run by pressing the ON/OFF
operation button of the remote controller. (Fig. 59a)
• This starts the fan producing uncooled forced air with
the 3 indicator lamps (OPERATION lamp, TIMER
lamp, and LED CLEAN lamp) on the main unit
blinking. (Fig. 59c)
• After 3 minutes, the system shifts into cooling opera-
tion, and cool air will start to be felt. Cooling mode test
run is unaffected by the room temperature.
(3) Press the ON/OFF operation button of the remote con-
troller again to stop the test run. (Fig. 59a)
(4) Finally press the ACL (Reset) button of the remote con-
troller to release it from Test Run mode to return to nor-
mal mode. (Fig. 59a)
• “ ” and “oP-1” will disappear from the remote con-
troller clock display area.
Troubleshooting:
In the event that the green OPERATION lamp is blinking
upon powering up the system, an error condition exists. In
this case, refer to the self-diagnostics procedure on the
inside of the front cover.
After the test run is completed, be sure to press the ACL
(Reset) button to return to normal mode. The air conditioner
will not operate correctly if this is not done.

■Pump Down
Pump down means collecting all refrigerant gas in the
system back into the outdoor unit without losing any of
the gas. Pump down is used when the unit is to be
moved or before servicing the refrigerant circuit.
Pump Down Procedure
Be sure to carry out pump down with the unit in
cooling mode.
(1) Connect the Lo side charging hose of the manifold
valve to the service port on the wide tube service
valve.
(2) Using a hex wrench, turn the narrow tube service
valve clockwise all the way to close the service
valve. (Be sure to confirm that the wide tube service
valve is fully open.)
(3) Press the operation button and start cooling oper-
ation.
(4) When the low pressure gauge reading falls to 14.2 to
7.1 psi (1 to 0.5 kg/cm2), fully close the wide tube
valve stem. Then quickly stop the unit.
(5) Disconnect all gauges and hoses, and replace the
valve caps as they were before.

7. Remote Control Unit Installation Position
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:
●In direct sunlight
●Behind a curtain or other place where it is covered
●More than 26' (8 m) away from the air conditioner
●In the path of the air conditioner’s airstream
●Where it may become extremely hot or cold
●Where it may be subject to electrical or magnetic
interference
●Where there is an obstacle between the remote con-
trol unit and the air conditioner (since a check signal
is sent from the remote control unit every 5 minutes)
7-1. Mounting on a Wall
Before mounting the remote control unit, press the
ON/OFF operation button at the mounting location to
make sure that the air conditioner operates from that
location. The indoor unit should make a beeping sound
to indicate that it has received the signal.

8. Address Switch
8-1. Address Setting of the Remote Control Unit
The address can be set in order to prevent interference
between remote controllers when 2 indoor units are
installed near each other. The address is normally set to
“A.” To set a different address, it is necessary to change
the address on the second remote controller.
Once changed, you cannot restore the original address
setting of the air conditioner.
(1) Switch on the power source.
(2) Break the address-setting tab marked “A” on the
second remote controller to change the address
(Fig. 62). When the tab is removed, the address is
automatically set to B (Fig. 63).
(3) Press and hold the remote controller QUIET button
and 1HR. 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 the ACL
button first, then release the QUIET and 1HR.
TIMER buttons. “oP-1” (Test Run) appears, blinking
in the remote controller clock display area.
(4) Each time the 1HR. TIMER button is pressed, the
display changes as shown below. Press this button
3 times to change the display to “oP-7” (Address
setting). (Fig. 64)
(5) “oP-7” has now been selected for address setting.
(6) Press the ON/OFF operation button on the remote
controller. (Fig. 64) Check that the “beep”signal-
received sound is heard from the second indoor unit
(approximately 5 times). The sound you hear is the
signal that the remote controller address has been
changed.
(7) Finally press the remote controller ACL (Reset) but-
ton to cancel the blinking “oP-7” display.
