7. OPERATION DESCRIPTION

FILE NO. SVM-02005(1)

7-1. Outline of Air Conditioner Control

This is a fixed capacity type air conditioner, which uses
a AC motor for an indoor fan. The AC motor drive
circuit is mounted in the indoor unit. And electrical
parts which operate the compressor and the outdoor
fan motor, are mounted in the outdoor unit.
The air conditioner is mainly controlled by the indoor
unit controller. The controller operates the indoor fan
motor based upon commands transmitted by the
remote control and transfers the operation commands
to the outdoor unit controller.
The outdoor unit controller receives operation
commands from the indoor unit, and operates the
outdoor fan motor and the compressor.

(1) Role of indoor unit controller

The indoor unit controller receives the operation

commands from the remote control and executes
them.

• Temperature measurement at the air inlet of the
indoor heat exchanger by the indoor
temperature sensor

• Temperature setting of the indoor heat
exchanger by the heat exchanger sensor

• Louver motor control

• Indoor fan motor operation control

• LED display control

• Transferring of operation commands to the

outdoor unit

• Receiving of information of the operation status
and judging of the information or indication of
error

7-1-1. Louver control

(1)Vertical air flow louver

Position of veritcal air flow louver is automatically
controlled according to the operation mode.
Besides, position of vertical air flow louver can be
arbitrarily set by pressing [FIX] button.
The louver position which is set by [FIX] button is
stored in the microcontroller, and the louver is
automatically set at the stored position for the next
operation.

(2)Swing

If [SWING] button is pressed when the indoor unit is
in operation, the vertical air flow louver starts
swinging. When [FIX] button is pressed, it stops
swinging.

7-1-2. Indoor fan control (AC fan motor)

(1)The indoor fan is operated by the stepless speed

change AC motor.

(2)For air flow level, speed of the indoor fan motor is

controlled in five steps (LOW, LOW

+

, MED, MED
and HIGH). If AUTO mode is selected, the fan
motor speed is automatically controlled by the
difference between the preset temperature and the
room temperature.

8. INSTALLATION PROCEDURE

8-1. Safety Cautions

For general public use

Power supply cord of parts of appliance for Outdoor use shall be at least polychloroprene sheathed flexible
cord (design H07 RN-F), or cord designation 245 IEC 66.

CAUTION

• THIS AIR CONDITIONER USES THE NEW HFC REFRGERANT (R-410A), WHICH DOES NOT

DESTROY THE OZONE LAYER.

R-410A refrigerant is apt to be affected by impurity such as water, oxidizing membranes, and oils because
the pressure of R-410A refrigerant is approx. 1.6 times of refrigerant R-22. 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 into the refrigerating 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. Accordingly, special tools are required for the new refrigerant (R-410A) as shown below. For
connecting pipes, use new and clean piping materials with high-pressure withstand capabilities, designed for
R-410A 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.
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.

FILE NO. SVM-02005(1)

DANGER

• FFOR 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, HEATORS,
FURNACE, STOVES, ETC.

• WHEN MOVING THE AIR-CONDITIONER FOR INSTALLING IT IN ANOTHER PLACE AGAIN, BE VERY
CAREFUL NOT TO GET THE SPECIFIED REFRIGERANT (R-410A) 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 instruc-

tions 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 do 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 electrical ovens.

4. For power details of the air conditioner, refer to the rating plate of the product.

8-5-3. 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 into the air conditioner, which use R-410A,
refrigeration cycle trouble may result.)

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 start 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.)
Then confirm that the compound pressure gauge
reading is –101 kPa (–76 cmHg).

5. Close the low pressure side 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.
