Power supply cord of parts of appliance for outdoor use shall be at least polychloroprene sheathed flexible cord (design H07RN-F) or cord
designation 245 IEC66. (Shall be installed in accordance with national wiring regulations.)
CAUTION
• THIS AIR CONDITIONER USES THE NEW HFC REFRIGERANT (R410A), WHICH DOES NOT DESTROY THE OZONE LAYER.
R410A refrigerant is apt to be affected by impurities such as water, oxidizing membranes, and oils because the pressure of R410A refrigerant is
approx. 1.6 times of refrigerant R22. As well as the adoption of this new refrigerant, refrigerating machine oil has also been changed. Therefore,
during installation work, be sure that water, dust, former refrigerant, or refrigerating machine oil does not enter the refrigeration cycle of a
new-refrigerant air conditioner.
To avoid mixing refrigerant and refrigerating machine oil, the sizes of charging port connecting sections on the main unit are different from those
for the conventional refrigerant, and different size tools are also required. For connecting pipes, use new and clean piping materials with highpressure withstand capabilities, designed for R410A only, and ensure that water or dust does not enter. Moreover, do not use any existing piping
as its pressure withstand may be insufficient and may contain impurities.
CAUTION
This appliance must be connected to the main power supply by means of a circuit breaker or a switch with a contact separation of at least 3 mm in
all poles. If this is not possible, a power supply plug with earth must be used. This plug must be easily accessible after installation. The plug must
be disconnected from the power supply socket in order to disconnect the appliance completely from the mains.
New refrigerant air conditioner installation
To disconnect the appliance from the main power supply
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.
• CONNECT THE CONNECTING CABLE CORRECTLY. IF THE CONNECTING CABLE IS CONNECTED WRONGLY, ELECTRIC PARTS MAY
BE DAMAGED.
• CHECK THE EARTH WIRE THAT IT IS NOT BROKEN OR DISCONNECTED BEFORE INSTALLATION.
• DO NOT INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS OR GAS VAPORS.
FAILURE TO FOLLOW THIS INSTRUCTION CAN RESULT IN FIRE OR EXPLOSION.
• TO PREVENT OVERHEATING THE INDOOR UNIT AND CAUSING A FIRE HAZARD, PLACE THE UNIT WELL AWAY (MORE THAN 2 M)
FROM HEAT SOURCES SUCH AS RADIATORS, HEATERS, FURNACE, STOVES, ETC.
• WHEN MOVING THE AIR CONDITIONER FOR INSTALLING IT IN ANOTHER PLACE AGAIN, BE VERY CAREFUL NOT TO GET THE
SPECIFIED REFRIGERANT (R410A) WITH ANY OTHER GASEOUS BODY INTO THE REFRIGERATION CYCLE. IF AIR OR ANY OTHER
GAS IS MIXED IN THE REFRIGERANT, THE GAS PRESSURE IN THE REFRIGERATION CYCLE BECOMES ABNORMALLY HIGH AND IT
RESULTINGLY CAUSES BURST OF THE PIPE AND INJURIES ON PERSONS.
• 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 BY FIRE OR SOMETHING ELSE, IT CAUSES GENERATION OF
POISONOUS GAS.
WARNING
• Never modify this unit by removing any of the safety guards or bypassing any of the safety interlock switches.
• 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.
• Before doing the electrical work, attach an approved plug to the power supply cord.
Also, make sure the equipment is properly earthed.
• 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 could result in electric shock.
Do not store it in a wet basement or expose to rain or water.
• After unpacking the unit, examine it carefully for possible 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 and 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 for proper installation.
REQUIREMENT OF REPORT TO THE LOCAL POWER SUPPLIER
Please make absolutely sure that the installation of this appliance is reported to the local power supplier before installation. If you experience any
problems or if the installation is not accepted by the supplier, the service agency will take adequate countermeasures.
Remark per EMC Directive 89/336/EEC
To prevent flicker impressions during the start of the compressor (technical process), following installation conditions does apply.
1. The power connection for the air conditioner has to be done at the main power distribution. This distribution has to be of an impedance.
Normally, the required impedance is reached at a 32A fusing point. Air conditioner fuse has to be 16A max.!
2. No other equipment should be connected to this power line.
3. For detailed installation acceptance, please contact your power supplier whether its restriction does apply for products like washing machines,
air conditioners or electric ovens.
4. For power details of the air conditioner, refer to the rating plate of the product.

OUTDOOR UNIT
Installation Place
• A place which provides the spaces 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 your neighbors
• A place which is not exposed to a strong wind
• A place free of a leakage of combustible gases
• A place which does not block a passage
• When the outdoor unit is to be installed in an elevated position,
be sure to secure its feet.
• An allowable length of the connecting pipe is up to 15 m.
• An allowable height level is up to 6 m.
• A place where the drain water does not raise any problems
CAUTION
1.Install the outdoor unit without anything blocking the air
discharging.
2.When the outdoor unit is installed in a place always exposed
to strong wind like a coast or on a high storey of a building,
secure the normal fan operation using a duct or a windshield.
3.In particularly windy areas, install the unit such as to avoid
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 as from
audio equipment, welders,

• Tightening torque of flare pipe connections
The operating pressure of R410A is higher than that of R22
(approx. 1.6 times). It is therefore necessary to firmly tighten the
flare pipe connecting sections (which connect the indoor and
outdoor units) up to the specified tightening torque. Incorrect
connections may cause not only a gas leakage, but also damage
to the refrigeration cycle.

CAUTION
• KEEP IMPORTANT 4 POINTS FOR PIPING WORK.
(1) Take away dust and moisture (inside of the connecting pipes).
(2) Tighten the connections (between pipes and unit).
(3) Evacuate the air in the connecting pipes using a VACUUM
PUMP.
(4) Check gas leak (connected points).
Evacuating
After the piping has been connected to the indoor unit, you can
perform the air purge together at once.
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 manual of the vacuum pump.
Using a vacuum pump
Be sure to use a vacuum pump with counter-flow prevention
function so that inside oil of the pump does not flow backward into
pipes of the air conditioner when the pump stops.
(If oil inside of the
vacuum pump enters
the air conditioner, which
use R410A, refrigeration
cycle trouble may result.)
