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
• RAS-4M23SAV-E, RAS-4M23SACV-E
Power supply cord of outdoor unit shall be 1.5 mm
• RAS-3M26GAV-E, RAS-4M27GAV-E, RAS-4M27GACV-E
Power supply cord of outdoor unit shall be 2.5 mm
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 as that 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 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 of 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.

ENGLISH
TO DISCONNECT THE APPLIANCE FROM THE MAIN POWER SUPPLY
Disconnection from the supply mains:
The means for disconnection must be incorporated in the fixed wiring in accordance with the wiring rules.
1 EN
OutdoorInstallation.book Page 2 Tuesday, February 13, 2007 5:58 PM
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 THE UNIT IN A PLACE WHERE INFLAMMABLE GAS CAN LEAK. A FIRE CAN RESULT IF
INFLAMMABLE GAS ACCUMULATES AROUND THE UNIT.
• 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 TO 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 MIXES WITH THE REFRIGERANT, THE GAS PRESSURE IN
THE REFRIGERATION CIRCUIT WILL BECOME ABNORMALLY HIGH AND IT MAY RESULT IN THE PIPE BURSTING OR
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, POISONOUS GAS MAY
RESULT.
• WHEN INSTALLING THE AIR CONDITIONER UNIT, MAKE SURE THAT THE REFRIGERANT PIPE IS CONNECTED
SECURELY BEFORE THE COMPRESSOR IS OPERATED. IF THE COMPRESSOR IS OPERATED WITH THE
REFRIGERANT PIPE UNCONNECTED, WHICH MEANS THAT THE SERVICE VALVE WILL BE LEFT OPEN, AIR, ETC.
WILL BE SUCKED IN, CAUSING THE PRESSURE INSIDE THE REFRIGERATION CYCLE TO RISE TO AN
ABNORMALLY HIGH LEVEL, AND POSSIBLY RESULTING IN RUPTURE, 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.
• The installation of the air conditioner must be positioned in a location that can sufficiently support its weight. Failure to do so
may result in unit damage and human injury.
• 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.

Installation/Service Tools
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)

4 INSTALLATION OF OUTDOOR UNIT
Installation Location
• 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, C, D, 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.

* 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.
*1 If the total piping length for the 4M23 is 40 m or more, add an extra 20 g/m of refrigerant.
*2 If a 4-way air discharge cassette type is connected to the 4M27, the maximum piping length is 50 m.
• 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.
NOTE: For installation, at least 3 sides should be kept
away from obstacles (walls).

CAUTION
1. Install the outdoor unit in a location where there are no obstructions near its air intake or air outlet.
2. When the outdoor unit is installed in a place that is 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.
Strong
wind
Draining the water (heat pump models only)
A hole is provided on the base plate of the outdoor unit to ensure that the defrost water produced during heating operations is drained
off efficiently.
When the outdoor unit is to be installed in an area with a moderate
climate
• Allow the water in the outdoor unit to drip onto the ground.
• If a centralized drain is required, which is the case when the unit is installed on a
balcony or against a wall, follow the steps below.
• When a drain pipe is to be used to drain the water
• Use a drain pan to catch the defrost water, and drain the pan.
• Use a pipe made of hard PVC with a nominal diameter of 25A (25 mm inside
diameter) for the drain pipe.

Tips when using a drain pan and elbow
• When using a drain pan, check its dimensions before deciding where the
outdoor unit is to be installed.
• When the elbow supplied is to be used, be advised that its dimensions are as
shown in the figure. Ensure that the foundation does not protrude beyond
where the elbow and the part of the hose connected to it are to be installed.
• When draining off the water using a drain nipple
When a drain hose is to be used to drain the water, install the drain nipple and
water-proofing rubber cap shown in the figure, and use a commercially available
drain hose (16 mm inside diameter). Tightly seal the knock-out holes and screw/
thread areas using a silicon adhesive, etc. to ensure that there is no water
drippage. Under some conditions, condensation may form on the base plate and
drip down. When all the defrost water is to be drained off using a centralized
drain, use the drain pan.
When the outdoor unit is to be installed in an area with a snowy or
cold climate
• Allow the water in the outdoor unit to drip onto the ground. (Do not use a hose to
drain off the water.)
• The drain water may freeze inside the base plate at below freezing outside air
temperatures so use a screwdriver or other tool to open the knock-out holes in
the base plate.
The water will drain more efficiently when the knock-out holes are opened. (Use
a screwdriver or other tool to pull out the knock-out pieces.)
