IMPORTANT NOTICE
• For details on how to install the indoor units, refer to the installation manual accompanying the indoor units.
1 SAFETY PRECAUTIONS
For general public use
Power supply cord of outdoor unit shall be 1.5 mm2(H07RN-F or 60245IEC66) polychloroprene sheathed flexible cord.
CAUTION
New Refrigerant Air Conditioner Installation
• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY OZONE
LAYER.
R410A refrigerant is apt to be affected by impurities such as water, oxidizing membrane, and oils because the working pressure of
R410A refrigerant is approx. 1.6 times of refrigerant R22. Accompanied with the adoption of the new refrigerant, the refrigeration
machine oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or
refrigeration machine oil does not enter into the new type refrigerant R410A air conditioner circuit.
To prevent mixing of refrigerant or refrigerating machine oil, the sizes of connecting sections of charging port on main unit and
installation tools are different from those used for the conventional refrigerant units. Accordingly, special tools are required for the
new refrigerant (R410A) units as shown on page 4. For connecting pipes, use new and clean piping materials with high pressure
fittings made for R410A only, so that water and/or dust does not enter. Moreover, do not use the existing piping because there are
some problems with pressure fittings and possible impurities in existing piping.
CAUTION
TO DISCONNECT THE APPLIANCE FROM THE MAIN POWER SUPPLY
This appliance must be connected to the main power supply by a circuit breaker or a switch with a contact separation of at least
3mm.

DANGER
• FOR USE BY QUALIFIED PERSONS ONLY.
• TURN OFF MAIN POWER SUPPLY BEFORE ATTEMPTING ANY ELECTRICAL WORK. MAKE SURE ALL POWER
SWITCHES ARE OFF. FAILURE TO DO SO MAY CAUSE ELECTRIC SHOCK.
• CORRECTLY CONNECT THE CONNECTING CABLE. IF THE CONNECTING CABLE IS INCORRECTLY CONNECTED,
ELECTRIC PARTS MAY BE DAMAGED.
• CHECK THAT THE EARTH WIRE IS NOT BROKEN OR DISCONNECTED BEFORE INSTALLATION. FAILURE TO DO SO
MAY CAUSE ELECTRIC SHOCK.
• DO NOT INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS OR GAS VAPORS. FAILURE TO FOLLOW THIS
INSTRUCTION CAN RESULT IN FIRE OR EXPLOSION.
• TO PREVENT THE INDOOR UNIT FROM OVERHEATING AND CAUSING A FIRE HAZARD, PLACE THE UNIT WELL
AWAY (MORE THAN 2 M) FROM HEAT SOURCES SUCH AS RADIATORS, HEAT REGISTORS, FURNACE, STOVES,
ETC.
• WHEN MOVING THE AIR-CONDITIONER FOR INSTALLATION IN ANOTHER PLACE, BE VERY CAREFUL NOT TO
ALLOW THE SPECIFIED REFRIGERANT (R410A) TO BECOME MIXED WITH ANY OTHER GASEOUS BODY INTO THE
REFRIGERATION CIRCUIT. IF AIR OR ANY OTHER GAS IS MIXED IN THE REFRIGERANT, THE GAS PRESSURE IN
THE REFRIGERATION CIRCUIT WILL BECOME ABNORMALLY HIGH AND IT MAY RESULT IN THE PIPE BURSTING
AND POSSIBLE PERSONNEL INJURIES.
• IN THE EVENT THAT THE REFRIGERANT GAS LEAKS OUT OF THE PIPE DURING THE INSTALLATION WORK,
IMMEDIATELY LET FRESH AIR INTO THE ROOM. IF THE REFRIGERANT GAS IS HEATED, SUCH AS BY FIRE,
GENERATION OF POISONOUS GAS MAY RESULT.
• WHEN CARRYING OUT THE INSTALLATION WORK, CONNECT THE REFRIGERANT PIPE SECURELY BEFORE
OPERATING THE COMPRESSOR. OPERATING THE COMPRESSOR WITH THE SERVICE VALVE LEFT OPEN AND
WITHOUT FIRST CONNECTING THE REFRIGERANT PIPE WILL CAUSE AIR, ETC. TO BE SUCKED IN, RAISING THE
PRESSURE INSIDE THE REFRIGERATION CYCLE TO AN ABNORMALLY HIGH LEVEL, AND POSSIBLY RESULTING IN
RUPTURING, INJURY, ETC.
• WHEN CARRYING OUT THE PUMP-DOWN WORK, SHUT DOWN THE COMPRESSOR BEFORE DISCONNECTING
THE REFRIGERANT PIPE. DISCONNECTING THE REFRIGERANT PIPE WITH THE SERVICE VALVE LEFT OPEN AND
WITH THE COMPRESSOR STILL OPERATING WILL CAUSE AIR, ETC. TO BE SUCKED IN, RAISING THE PRESSURE
INSIDE THE REFRIGERATION CYCLE TO AN ABNORMALLY HIGH LEVEL, AND POSSIBLY RESULTING IN
RUPTURING, INJURY, ETC.
WARNING
• Never modify this unit by removing any of the safety guards.
• Do not install in a place which cannot bear the weight of the unit. Personal injury and property damage can result if the unit
falls.
• Appliance shall be installed in accordance with national wiring regulations.
• If you detect any damage, do not install the unit. Contact your Toshiba dealer immediately.
CAUTION
• Exposure of unit to water or other moisture before installation may result in an electrical short. Do not store in a wet
basement or expose to rain or water.
• After unpacking the unit, examine it carefully for any damage.
• Do not install in a place that can increase the vibration of the unit. Do not install in a place that can amplify the noise level of
the unit or where noise or discharged air might disturb neighbors.
• To avoid personal injury, be careful when handling parts with sharp edges.
• Please read this installation manual carefully before installing the unit. It contains further important instructions necessary for
proper installation.
• Wear work gloves when carrying out the installation work or repairs. Contact with parts, etc. may cause injury if the work or
repairs are conducted without wearing gloves.

Changes in the product and components
In air conditioners using R410A, in order to prevent any other refrigerant from being accidentally charged, the service port diameter
size of the outdoor unit control valve (3 way valve) has been changed. (1/2 UNF 20 threads per inch)
• In order to increase the pressure resisting strength of the refrigerant piping, flare processing diameter and opposing flare nuts sizes
have been changed. (for copper pipes with nominal dimensions 1/2 and 5/8)
New tools for R410A
• Incidentally, the “refrigerant cylinder” comes with the refrigerant designation (R410A) and protector coating in the U.S’s ARI
specified rose color (ARI color code: PMS 507).
• Also, the “charge port and packing for refrigerant cylinder” requires 1/2 UNF 20 threads per inch corresponding to the charge hose’s
port size.
Installation/Service Tools
New tools for R410A Applicable to R22 model Changes
Gauge manifold As the working pressure is high, it is impossible to measure
the working pressure using conventional gauges. In order to
prevent any other refrigerant from being charged, the port
diameters have been changed.
Charge hose In order to increase pressure resisting strength, hose
materials and port sizes have been changed (to 1/2 UNF 20
threads per inch).
When purchasing a charge hose, be sure to confirm the
port size.
Electronic balance for refrigerant
charging
As working pressure is high and gasification speed is fast, it
is difficult to read the indicated value by means of charging
cylinder, as air bubbles occur.
Torque wrench
(nominal dia. 1/2, 5/8)
The size of opposing flare nuts have been increased.
Incidentally, a common wrench is used for nominal
diameters 1/4 and 3/8.
Flare tool (clutch type) By increasing the clamp bar’s receiving hole size, strength
of spring in the tool has been improved.
Gauge for projection adjustment — Used when flare is made by using conventional flare tool.
Vacuum pump adapter Connected to conventional vacuum pump. It is necessary to
use an adapter to prevent vacuum pump oil from flowing
back into the charge hose. The charge hose connecting
part has two ports — one for conventional refrigerant (7/16
UNF 20 threads per inch) and one for R410A. If the vacuum
pump oil (mineral) mixes with R410A a sludge may occur
and damage the equipment.
Gas leakage detector Exclusive for HFC refrigerant.

• A place which provides enough space around the outdoor
unit as shown in the diagram.
• A place which can bear the weight of the outdoor unit and
does not allow an increase in noise level and vibration.
• A place where the operation noise and discharged air do not
disturb neighbors.
• A place which is not exposed to a strong wind.
• A place free of combustible gases.
• A place which does not block a passageway.
• When the outdoor unit is to be installed in an elevated
position, be sure to secure its feet.
• Piping connections to the outdoor unit should be arranged in
the sequence A, then B, starting from the bottom. (For each
piping connection, the gas pipe is on the bottom and the
liquid pipe on top.)
• When multiple indoor units are to be connected to the
outdoor unit, make sure the ends of the pipes and wires from
each indoor unit are connected to the outdoor unit correctly.
(Problems caused by indoor units being connected to the
outdoor unit incorrectly are very common in multiple-unit
installations.)
• The length and height differences of the connecting pipes,
between the indoor and outdoor units, must be within the
ranges indicated below.
• Total piping length:
Two room (A+B) Multi
• This air conditioner accepts a connection piping length
of up to 30 m.
• There is no need to add refrigerant as long as the
length of the connection piping is 20 m or less.
• You will need to add 20 g of refrigerant per meter of
added connection piping for installations requiring
connection piping to be between 21 m to 30 m.
• Minimum piping length:
A or B = 2 m or more
• Maximum indoor piping length:
A or B = 20 m or less
• Maximum piping height difference:
A or B = 10 m or less
• Maximum piping / height difference
between two rooms = 10 m or less
• If the outdoor unit is to be mounted on a wall, make sure the platform supporting it is sturdy enough.
The platform should be designed and manufactured to maintain its strength over a long period of time, and sufficient consideration
should be given to ensuring that the outdoor unit will not fall.
• When the outdoor unit is to be mounted high on a wall, take particular care to ensure that parts do not fall, and that the installer is
protected.
• When doing installation work at ground level, it is usual to make wiring and pipe connections to the indoor units, first, and then to
make connections to the outdoor unit.
However, if outdoor work is difficult it is possible, instead, to make changes to the procedure.
For example, by making adjustments to the wiring and piping lengths on the inside (rather than the outside).
• A place where the drain water does not cause any problems.
• The outdoor unit should not be installed with one indoor unit only. Be sure the (outdoor) unit is installed with at least two indoor
units.
Precautions for Adding Refrigerant
• Use a scale having a precision with at least 10 g per index line when adding the refrigerant. Do not use a bathroom scale or similar
instrument.
• Use liquid refrigerant when refilling the refrigerant. Since the refrigerant is in liquid form, it can fill quickly. Therefore, perform the
filling operation carefully and insert the refrigerant gradually.

• Holes are provided on the base plate of the outdoor unit to ensure that the
defrost water produced during heating operations is drained off efficiently. If a
centralized drain is required when installing the unit on a balcony or wall, follow
the steps below to drain off the water.
1. Proceed with water-proofing by installing the water-proof rubber caps din the
2 elongated holes on the base plate of the outdoor unit.
[How to install the water-proof rubber caps]
1) Place four fingers into each cap, and insert the caps into the water drain
holes by pushing them into place from the underside of the base plate.
2) Press down on the outer circumferences of the caps to ensure that they
have been inserted tightly.
(Water leaks may result if the caps have not been inserted properly, if their
outer circumferences lift up or the caps catch on or wedge against
something.)
2. Install the drain nipple cand a commercially available drain hose (with 16 mm
inside diameter), and drain off the water.
(For the position where the drain nipple cis installed, refer to the installation
diagram of the indoor and outdoor units.)
• Check that the outdoor unit is horizontal, and route the drain hose at a
downward sloped angle while ensuring that it is connected tautly.
CAUTION
1. Install the outdoor unit without anything blocking the discharging air.
2. When the outdoor unit is installed in a place always exposed to strong winds like on the coast or on a high story of a
building, secure the normal fan operation using a duct or a wind shield.
3. Especially in windy areas, install the unit to prevent the admission of wind.
4. Installation in the following places may result in trouble. Do not install the unit in such places.
• A place full of machine oil.
• A saline-place such as the coast.
• A place full of sulfide gas.
• A place where high-frequency waves are likely to be generated, such
as from audio equipment, welders, and medical equipment.

• Tightening torque for connection of flare pipe
The pressure of R410A is higher than R22. (Approx. 1.6 times.) Therefore securely tighten the flare pipes which connect the outdoor
unit and the indoor unit with the specified tightening torque using a torque wrench.
If any flare pipe is incorrectly connected, it may cause not only a gas leakage but also trouble in the refrigeration cycle.
*1 When connecting a capacity class 16 pipe to the indoor unit, attach the
expander which is available as an optional accessory to the 9.52 mm
diameter packed valve of the outdoor unit.
After the piping has been connected to the indoor unit, perform the air purge.
Use a vacuum pump
Be sure to use a vacuum pump with counter-flow prevention function so that
oil inside the pump does not flow back into the air conditioner pipes when the
pump stops. (If oil inside the vacuum pump enters into the air conditioner
circuit which uses R410A, trouble with the refrigeration system may develop.)
1. Connect the charge hose from the manifold valve to the service port of
the gas side packed valve.
2. Connect the charge hose to the port of the vacuum pump.
3. Open fully the low pressure side handle of the gauge manifold valve.
4. Operate the vacuum pump to begin evacuating. Perform evacuating for
about 15 minutes if the piping length is 20 meters (15 minutes for 20
meters) (assuming a pump capacity of 27 liters per minute). Confirm that
the compound pressure gauge reading is –101 kPa (–76 cmHg).
5. Close the low pressure valve handle of gauge manifold.
6. Open fully the valve stem of the packed valves (both sides of Gas and
Liquid).
7. Remove the charging hose from the service port.
8. Securely tighten the caps on the packed valves.
9. Perform steps 1 through 8 above on each connected indoor unit.

Evacuating
AIR PURGE
Evacuate the air in the connecting pipes and in the indoor unit using a vacuum pump. Do not use the refrigerant in the outdoor unit.
For details, see the vacuum pump manual.
CAUTION
• IMPORTANT POINTS FOR PIPING WORK
(1) Keep dust and moisture from entering the pipes.
(2) Tighten connections carefully (between pipes and unit).
(3) Evacuate the air in the connecting pipes using a VACUUM PUMP.
(4) Check for gas leaks at all connections.

• Securely tighten the valve stem cap with torque in the following table:
1. Remove the valve cover, the electric parts cover and the cord clamp from the outdoor unit.
2. Connect the connecting cable to the terminal as identified by the matching numbers on the terminal block of indoor and outdoor
unit.
3. Insert the power cord and the connecting cable fully into the terminal block and secure it tightly with screws.
4. Insulate the unused cords (conductors) from water entering in the outdoor unit. Locate them so that they do not touch any
electrical or metal parts.
5. Secure the power cord and the connecting cable with the cord clamp.
6. Attach the electric parts cover and the valve cover on the outdoor unit.

ENGLISH
This air conditioner must be grounded without fail.
Grounding is necessary not only to safeguard against the possibility of receiving an electric shock but also to absorb both the static,
which is generated by high frequencies and held in the surface of the outdoor unit, and noise since the air conditioner incorporates a
frequency conversion device (called an inverter) in the outdoor unit. If the air conditioner is not grounded, users may receive an
electric shock if they touch the surface of the outdoor unit and that unit is charged with static.
* The conventional leak detector for HCFC refrigerant (R22, etc.) cannot be used because its sensitivity for HFC refrigerant lowers to
approx. 1/40 of that manufactured exclusively for HFC refrigerant.
• Pressure of R410A becomes approx. 1.6 times that of R22. If
installation work has not completely finished, gas leaks may occur in
cases such as when pressure rises during operation.
• Check the flare nut connections, valve stem cap connections and
service port cap connections for gas leaks with a leak detector or
soap water.
Make sure that the wiring and piping for each room have the same alphabetical code (A, B).
Connect and secure the power cord.
Use the power cord/cables with thickness, type, and protective devices specified in this manual.
Insulate the unused cords (conductors) with PVC tape.
1. Turn on the electrical power breaker.
2. Operate the indoor unit in cooling mode.
3. Start checks.
• Run the indoor unit in room A, and confirm cool air blows out.
• Confirm the indoor unit in room B is not running. (Also check at this time that refrigerant, which can be heard, is not flowing.)
• Stop operation of the indoor unit in room A and execute the same checks on the indoor unit in room B.
5 GROUNDING
6 CHECK AND TEST OPERATION
For R410A, use the leak detector exclusively manufactured for HFC refrigerant (R410A, R134a, etc.)
CAUTION
• Use a circuit breaker of a type that is not tripped by shock waves.
• Incorrect/incomplete wiring will cause electrical fires or smoke.
• Prepare the power source for exclusive use with the air conditioner.
• Proceed as follows when connecting the product to the mains power.
• Connection to fixed wiring:
A switch or circuit breaker which disconnects all poles and has a contact separation of at least 3 mm must be incorporated
into the fixed wiring.
Utilize only approved short circuit breakers and switches.
* (A breaker having sensitivity of approximately 0.1 second or less and capacity of approximately 30 mA is usually used.)

• For this outdoor unit, by referring to the 5 LED (Red) indicator lights, self-diagnosis is possible.
• LEDS (Red, D09 to D13) are located on the sub-control board underneath the inverter.
• These LEDs do not normally light.
1. If trouble occurs, LED (Red) goes on according to the contents of trouble
as shown in the table above.
2. When two or more troubles occur, LEDs go on cyclically (alternately).
3. When the trouble is eliminated, LEDs (Red) go off.
