PRECAUTIONS FOR SAFETY
1110251190-EN.indd 1
1/27/09 3:33:47 PM
Power supply cord of parts of appliance for outdoor use shall be at least polychloroprene sheathed fl exible cord (design H07RN-F) or cord designation 245
IEC66 (1.5 mm
2
or more). (Shall be installed in accordance with national wiring regulations.)
CAUTION
New refrigerant air conditioner installation
• THIS AIR CONDITIONER USES THE NEW HFC REFRIGERANT (R410A), WHICH DOES NOT DESTROY THE OZONE LAYER.
For general public use
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 insuffi cient 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.
The installation fuse (25A) must be used for the power supply line of this air conditioner.
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.

1. Die-cutting front panel slit
Cut out the slit on the leftward or right side of the front panel for the left or
right connection and the slit on the bottom left or right side of the front panel
for the bottom left or right connection with a pair of nippers.
2. Changing drain hose
For leftward connection, bottom-leftward connection and rearleftward
connection’s piping, it is necessary to change the drain hose and drain
cap.
How to remove the drain hose
• The drain hose can be removed by removing the
screw securing the drain hose and then pulling out
the drain hose.
• When removing the drain hose, be careful of any
sharp edges of steel plate. The edges can injuries.
• To install the drain hose, insert the drain hose
fi rmly until the connection part contacts with heat
insulator, and the secure it with original screw.
How to remove the drain cap
Clip the drain cap by needlenose pliers and pull out.
How to fi x the drain cap
1) Insert hexagon
wrench (4 mm)
in a center head.
2) Firmly insert the drain cap.
No gap
Insert a hexagon
wrench (4 mm).

• Bend the connecting pipe so that it is laid within 43 mm above the wall surface. If the connecting pipe is laid exceeding 43 mm above the wall surface,
the indoor unit may unstably be set on the wall.
When bending the connecting pipe, make sure to use a spring bender so as
not to crush the pipe.
Bend the connecting pipe within a radius of 30 mm.

If the pipe is bent incorrectly, the indoor unit may unstably be set on the wall.
After passing the connecting pipe through the pipe hole, connect the
connecting pipes to the auxiliary pipes and wrap the facing tape around
them.
CAUTION
• Bind the auxiliary pipes (two) and connecting cable with facing tape
tightly. In case of leftward piping and rear-leftward piping, bind the
auxiliary pipes (two) only with facing tape.

Auxiliary pipes
Installation plate
• Carefully arrange pipes so that any pipe does not stick out of the rear
plate of the indoor unit.
• Carefully connect the auxiliary pipes and connecting pipes to one another and cut off the insulating tape wound on the connecting pipe to
avoid double-taping at the joint; moreover, seal the joint with the vinyl
tape, etc.
• Since dewing results in a machine trouble, make sure to insulate both
connecting pipes. (Use polyethylene foam as insulating material.)
• When bending a pipe, carefully do it, not to crush it.
