1PRECAUTIONS FOR SAFETY
The three indoor units of TOSHIBA simultaneous triple packaged air conditioning
system are the same units. Set and install the header and follower units taking the
installation site into consideration. (Be certain to use the new refrigerant R410A in the
indoor units.) The indoor unit connected to the remote controller will be the header
unit.
• Ensure that all Local, National and International regulations are satisfied.
• Read indoor, outdoor installation manual and this manual carefully before Installation.
• The precautions described below include the important items regarding safety. Observe
them without fail.
• After the installation work, perform a trial operation to check for any problem.
Follow the Owner’s Manual to explain how to use and maintain the unit to the customer.
• Turn off the main power supply switch (or breaker) before the unit maintenance.
• Ask the customer to keep the Installation Manual together with the Owner’s Manual.
WARNING
• Ask an authorized dealer or qualified installation professional to install/maintain
the air conditioner.
Inappropriate installation may result in water leakage, electric shock or fire.
• Turn off the main power supply switch or breaker 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 in a wrong way, electric parts may be damaged.
• When moving the air conditioner for the installation into another place, be very
careful not to enter any gaseous matter other than the specified refrigerant 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 resultantly causes pipe burst and injuries on
persons.
• Do not modify this unit by removing any of the safety guards or by by-passing any
of the safety interlock switches.
• Exposure of unit to water or other moisture before installation may cause a short-
circuit of electrical parts.
Do not store it in a wet basement or expose to rain or water.
• After unpacking the units, examine them carefully if there are possible damage.
• Do not install in a place that might increase the vibration of the unit.
• To avoid personal injury (with sharp edges), be careful when handling parts.
• Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
• When the air conditioner is installed in a small room, provide appropriate
measures to ensure that the concentration of refrigerant leakage occur in the
room does not exceed the critical level.

3EN
Branch Kit 1:3
• Install the air conditioner securely in a location where the base can sustain the
weight adequately.
• Perform the specified installation work to guard against an earthquake.
If the air conditioner is not installed appropriately, accidents may occur due to the falling
unit.
• If refrigerant gas has leaked during the installation work, ventilate the room
immediately.
If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.
• After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source, such as a cooking
range, noxious gas might generate.
• Electrical work must be performed by a qualified electrician in accordance with
the Installation Manual. Make sure the air conditioner uses an exclusive power
supply.
An insufficient power supply capacity or inappropriate installation may cause fire.
• Use the specified cables for wiring connect the terminals securely fix. To prevent
external forces applied to the terminals from affecting the terminals.
• Conform to the regulations of the local electric company when wiring the power
supply.
Inappropriate grounding may cause electric shock.
• Do not install the air conditioner in a location subject to a risk of exposure to a
combustible gas.

CAUTION
New Refrigerant Air conditioner Installation
• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH
DOES NOT DESTROY OZONE LAYER.
• The characteristics of R410A refrigerant are; easy to absorb water, oxidizing membrane
or oil, and its pressure is approx. 1.6 times higher than that of refrigerant R22.
Accompanied with the new refrigerant, refrigerating oil has also been changed.
Therefore, during installation work, be sure that water, dust, former refrigerant, or
refrigerating oil does not enter the refrigerating cycle.
• To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting
sections of charging port of the outdoor unit and installation tools are changed from
those for the conventional refrigerant.
• Accordingly the exclusive tools are required for the new refrigerant. (R410A)
• For connecting pipes, use new and clean piping designed for R410A, and please care
so that water or dust does not enter. Moreover, do not use the existing piping because
there are problems with pressure-resistance force and impurity in it.
• The three indoor units of TOSHIBA simultaneous triple packaged air conditioning
system are the same units.
• Set and install the header and follower units taking the installation site into
consideration.
(Be certain to use the new refrigerant R410A in the indoor units.)
The indoor unit connected to the remote controller will be the header unit.
Wiring
• TO DISCONNECT THE APPLIANCE FROM MAIN POWER SUPPLY.
• This appliance must be connected to the main supply by means of a switch with a
contact separation of at least 3 mm.
• The remote controller cannot be connected to all the three indoor units (header and
follower units).
Connect it only to the indoor unit that will become the header indoor unit (Unit A).
Connecting the remote controller to the follower indoor unit will cause malfunction.
Refrigerant Piping (Branch piping system is used for refrigerant piping)
• Compared with R22, pressure of R410A is about 1.6 times. Unless the piping is installed
correctly, gas leak may be caused during operation such as pressure boosting. Conduct
a leak test of the pipe connecting parts correctly.
• In case the actual length of the piping exceeds the standard piping length, accurately
add the refrigerant referring to Additional Refrigerant Amount.
• Heat insulation materials for the branch pipes are not supplied as accessories. Provide
heat insulation correctly using fitting covers or other materials sold on the market. For
further information, read Refrigerant Piping and Piping heat Insulation on this manual.
Improper heat insulation work will result in a failure and a claim.
