Be sure to read the following safety cautions before conducting repair work.
The caution items are classified into “ Warning” and “ Caution”. The “ Warning”
items are especially important since they can lead to death or serious injury if they are not
followed closely. The “ Caution” items can also lead to serious accidents under some
conditions if they are not followed. Therefore, be sure to observe all the safety caution items
described below.
About the pictograms
This symbol indicates the item for which caution must be exercised.
The pictogram shows the item to which attention must be paid.
This symbol indicates the prohibited action.
The prohibited item or action is shown in the illustration or near the symbol.
This symbol indicates the action that must be taken, or the instruction.
The instruction is shown in the illustration or near the symbol.
After the repair work is complete, be sure to conduct a test operation to ensure that the
equipment operates normally, and explain the cautions for operating the product to the
customer.
1.1.1 Cautions Regarding Safety of Workers
Be sure to disconnect the power cable plug from the plug socket before
disassembling the equipment for repair.
Working on the equipment that is connected to the power supply may cause an
electrical shook.
If it is necessary to supply power to the equipment to conduct the repair or
inspecting the circuits, do not touch any electrically charged sections of the
equipment.
If the refrigerant gas is discharged during the repair work, do not touch the
discharged refrigerant gas.
The refrigerant gas may cause frostbite.
When disconnecting the suction or discharge pipe of the compressor at the
welded section, evacuate the refrigerant gas completely at a well-ventilated
place first.
If there is a gas remaining inside the compressor, the refrigerant gas or
refrigerating machine oil discharges when the pipe is disconnected, and it may
cause injury.
If the refrigerant gas leaks during the repair work, ventilate the area. The
refrigerant gas may generate toxic gases when it contacts flames.
Warning
The step-up capacitor supplies high-voltage electricity to the electrical
components of the outdoor unit.
Be sure to discharge the capacitor completely before conducting repair work.
A charged capacitor may cause an electrical shock.
Do not start or stop the air conditioner operation by plugging or unplugging the
power cable plug.
Plugging or unplugging the power cable plug to operate the equipment may
cause an electrical shock or fire.
vii
Introduction Si12-619A
Warning
Be sure to wear a safety helmet, gloves, and a safety belt when working at a
high place (more than 2m). Insufficient safety measures may cause a fall
accident.
In case of R410A refrigerant models, be sure to use pipes, flare nuts and tools
for the exclusive use of the R410A refrigerant.
The use of materials for R22 refrigerant models may cause a serious accident
such as a damage of refrigerant cycle as well as an equipment failure.
Caution
Do not repair the electrical components with wet hands.
Working on the equipment with wet hands may cause an electrical shock.
Do not clean the air conditioner by splashing water.
Washing the unit with water may cause an electrical shock.
Be sure to provide the grounding when repairing the equipment in a humid or
wet place, to avoid electrical shocks.
Be sure to turn off the power switch and unplug the power cable when cleaning
the equipment.
The internal fan rotates at a high speed, and cause injury.
Be sure to conduct repair work with appropriate tools.
The use of inappropriate tools may cause injury.
Be sure to check that the refrigerating cycle section has cooled down enough
before conducting repair work.
Working on the unit when the refrigerating cycle section is hot may cause
burns.
viii
Use the welder in a well-ventilated place.
Using the welder in an enclosed room may cause oxygen deficiency.
Si12-619A Introduction
1.1.2 Cautions Regarding Safety of Users
Warning
Be sure to use parts listed in the service parts list of the applicable model and
appropriate tools to conduct repair work. Never attempt to modify the
equipment.
The use of inappropriate parts or tools may cause an electrical shock,
excessive heat generation or fire.
If the power cable and lead wires have scratches or deteriorated, be sure to
replace them.
Damaged cable and wires may cause an electrical shock, excessive heat
generation or fire.
Do not use a joined power cable or extension cable, or share the same power
outlet with other electrical appliances, since it may cause an electrical shock,
excessive heat generation or fire.
Be sure to use an exclusive power circuit for the equipment, and follow the local
technical standards related to the electrical equipment, the internal wiring
regulations, and the instruction manual for installation when conducting
electrical work.
Insufficient power circuit capacity and improper electrical work may cause an
electrical shock or fire.
Be sure to use the specified cable for wiring between the indoor and outdoor
units. Make the connections securely and route the cable properly so that there
is no force pulling the cable at the connection terminals.
Improper connections may cause excessive heat generation or fire.
When wiring between the indoor and outdoor units, make sure that the terminal
cover does not lift off or dismount because of the cable.
If the cover is not mounted properly, the terminal connection section may cause
an electrical shock, excessive heat generation or fire.
Do not damage or modify the power cable.
Damaged or modified power cable may cause an electrical shock or fire.
Placing heavy items on the power cable, and heating or pulling the power cable
may damage the cable.
Do not mix air or gas other than the specified refrigerant (R410A / R22) in the
refrigerant system.
If air enters the refrigerating system, an excessively high pressure results,
causing equipment damage and injury.
If the refrigerant gas leaks, be sure to locate the leaking point and repair it
before charging the refrigerant. After charging refrigerant, make sure that there
is no refrigerant leak.
If the leaking point cannot be located and the repair work must be stopped, be
sure to perform pump-down and close the service valve, to prevent the
refrigerant gas from leaking into the room. The refrigerant gas itself is
harmless, but it may generate toxic gases when it contacts flames, such as fan
and other heaters, stoves and ranges.
When relocating the equipment, make sure that the new installation site has
sufficient strength to withstand the weight of the equipment.
If the installation site does not have sufficient strength and if the installation
work is not conducted securely, the equipment may fall and cause injury.
ix
Introduction Si12-619A
Warning
Check to make sure that the power cable plug is not dirty or loose, then insert
the plug into a power outlet securely.
If the plug has dust or loose connection, it may cause an electrical shock or fire.
Be sure to install the product correctly by using the provided standard
installation frame.
Incorrect use of the installation frame and improper installation may cause the
equipment to fall, resulting in injury.
Be sure to install the product securely in the installation frame mounted on the
window frame.
If the unit is not securely mounted, it may fall and cause injury.

1. Main Functions
Note: See the list of functions for the functions applicable to different models.
1.1 Frequency Principle
Main Control
Parameters
Additional
Control
Parameters
The compressor is frequency-controlled during normal operation. The target frequency is set by
the following 2 parameters coming from the operating indoor unit:
The load condition of the operating indoor unit
The difference between the room temperature and the set temperature
The target frequency is adapted by additional parameters in the following cases:
Frequency restrictions
Initial settings
Forced cooling / heating operation
Inverter Principle To regulate the capacity, a frequency control is needed. The inverter makes it possible to vary
the rotation speed of the compressor. The following table explains the conversion principle:
Phase Description
1 The supplied AC power source is converted into the DC power source for the present.
2 The DC power source is reconverted into the three phase AC power source with variable
frequency.
When the frequency increases, the rotation speed of the compressor increases resulting
in an increased refrigerant circulation. This leads to a higher amount of the heat
exchange per unit.
When the frequency decreases, the rotation speed of the compressor decreases
resulting in a decreased refrigerant circulation. This leads to a lower amount of the heat
exchange per unit.

Si12-619A Main Functions
Inverter Features The inverter provides the following features:
The regulating capacity can be changed according to the changes in the outdoor air
temperature and cooling / heating load.
Quick heating and quick cooling
The compressor rotational speed is increased when starting the heating (or cooling). This
enables a quick set temperature.

Start
Even during extreme cold weather, the high capacity is achieved. It is maintained even when
60 120 300
seconds
(R1187)
the outdoor air temperature is 2°C.
Comfortable air conditioning
A detailed adjustment is integrated to ensure a fixed room temperature. It is possible to air
condition with a small room temperature variation.
Energy saving heating and cooling
Once the set temperature is reached, the energy saving operation enables to maintain the
room temperature at low power.
Frequency Limits The following table shows the functions that define the minimum and maximum frequency:
Frequency limits Limited during the activation of following functions

Function and Control 79
Main Functions Si12-619A
1.2 Power-Airflow Dual Flaps, Wide Angle Louvers and
Auto-Swing
Power-airflow
Dual Flaps
The large flaps send a large volume of air downwards to the floor. The flap provides an optimum
control area in cooling, heating and dry mode.
Heating Mode
During heating mode, the large flap enables direct warm air straight downwards. The flap
presses the warm air above the floor to reach the entire room.
Cooling Mode
During cooling mode, the flap retracts into the indoor unit. Then, cool air can be blown far and
pervaded all over the room.
Wide-Angle
Louvers
The louvres, made of elastic synthetic resin, provide a wide range of airflow that guarantees a
comfortable air distribution.
Auto-Swing In case of FTK(X)S20-35D, FTK(X)S25/35E

3-D Airflow Wall Mounted Type 50-71 Class
Alternative repetition of vertical and horizontal swing motions enables uniform airconditioning of the entire room. This function is effective for starting the air conditioner.
When the horizontal swing and vertical swing are both set to auto mode, the airflow become
3-D airflow and the horizontal swing and vertical swing motions are alternated. The order of
swing motion is such that it turns counterclockwise, starting from the right upper point as
viewed to the front side of the indoor unit.

80 Function and Control
Si12-619A Main Functions
1.3 Fan Speed Control for Indoor Units
Control Mode The airflow rate can be automatically controlled depending on the difference between the set
temperature and the room temperature. This is done through rotation speed control, or phase
and Hall IC control.
For more information about Hall IC, refer to the troubleshooting for fan motor on page 214.
Fan speed Steps Phase control and fan speed control contains 9 steps: LLL, LL, SL, L, ML, M, MH, H and HH.

1.4 Programme Dry Function
Programme dry function removes humidity while preventing the room temperature from
lowering.
Since the microcomputer controls both the temperature and air flow volume, the temperature
adjustment and fan adjustment buttons are inoperable in this mode.
In Case of
Inverter Units
The microcomputer automatically sets the temperature and fan settings. The difference
between the room temperature at startup and the temperature set by the microcomputer is
divided into two zones. Then, the unit operates in the dry mode with an appropriate capacity for
each zone to maintain the temperature and humidity at a comfortable level.

1.5 Automatic Operation
Automatic Cooling / Heating Function (Heat Pump Only)
When the AUTO mode is selected with the remote controller, the microcomputer automatically
determines the operation mode from cooling and heating according to the room temperature
and setting temperature at the time of the operation startup, and automatically operates in that
mode.
The unit automatically switches the operation mode to cooling or heating to maintain the room
temperature at the main unit setting temperature.
Detailed
Explanation of
the Function
1. Remote controller setting temperature is set as automatic cooling / heating setting
temperature (18 to 30°C).
2. Main unit setting temperature equals remote controller setting temperature.
3. Operation ON / OFF point and mode switching point are as follows.

1.7 Night Set Mode
When the OFF timer is set, the Night Set circuit automatically activates.
The Night Set circuit maintains the airflow setting made by users.
The Night Set
Circuit
Cooling
Operation
The Night Set circuit continues heating or cooling the room at the set temperature for the first
one hour, then automatically raises the temperature setting slightly in the case of cooling, or
lowers it slightly in the case of heating, for economical operations. This prevents excessive
heating in winter and excessive cooling in summer to ensure comfortable sleeping conditions,
and also conserves electricity.
In case of FTK(X)S25-35E, FTK(X)S20-35D, FTK(X)S50-71F the temperature rises once.

1.8 ECONO Mode
Outline FTK(X)S20-35D, FTK(X)S25/35E
The "ECONO mode" reduces the maximum operating current and power consumption by
approx. 30% during start up etc..
This mode is particularly convenient for energy-saving-oriented users. It is also a major bonus
for those whose breaker capacities do not allow the use of multiple electrical devices and air
conditioners.
It is easily activated from the wireless remote controller by pushing the ECONO button.
When this function is ON, the maximum capacity is also down. (Approx. 20%)
This function can only be set when the unit is running. Pressing the operation stop button
causes the settings to be canceled.
This function and POWERFUL operation cannot be used at the same time. The latest
command has the priority.
