(a)
FDTC, FDT, FDEN, FDUM and FDU series
Auto operation
If “Auto” mode is selected by the remote controller, the heating and the cooling are automatically switched according to the
difference between outdoor air temperature and setting temperature and the difference between setting temperature and return
air temperature. (When the switching of cooling mode ¢ heating mode takes place within 3 minutes, the compressor does
not operate for 3 minutes by the control of 3-minute timer.) This will facilitate the cooling/heating switching operation in
intermediate seasons and the adaptation to unmanned operation at stores, etc (ATM corner of bank).

Plural unit control – Control of 16 units group by one remote controller
1)
Function
One remote controller switch can control a group of multiple number of unit (Max. 16 indoor units). “Operation mode”
which is set by the remote controller switch can operate or stop all units in the group one after another in the order of unit
No.(1). Thermostat and protective function of each unit function independently.
Note (1) Unit No. is set by SW2 on the indoor unit control PCB. Unit No. setting by SW2 is necessary for the indoor unit only. In cases of the twin, triple
and double-twin specification, it is necessary set for the master and the slave units. This can be selected by SW5. (All are set for the master unit at
the shipping from factory.)

d) In case of anomaly
i) If any anomaly occurs on a unit in a group (a protective function operates), that unit stops with the anomalous
stop but any other normal units continue to run as they are.
ii) Signal wiring procedure
Signal wiring between indoor and outdoor units should be made on each unit same as the normal wiring.
For the group control, lay connect with sires wiring between rooms using terminal blocks (X, Y) of remote
controller.
Connect the remote controller communication wire separately from the power supply wire or wires of other
electric devices (AC220V or higher).

Note (1) During defrosting and for 3 minutes after the end of defrosting, it is not detected.
• Discharge pipe temperature thermistor: -10°C or lower
• Suction pipe temperature thermistor: -50 or lower
(o) Open phase protection (3-phase models only)
When 0V is detected on any of L1, L2 or L3 phase for 5 seconds continuously after the power ON, it judges the state of
open phase on the power supply and activates the anomalous stop (E34) 1 second later.
(p) Fan motor error
1)
If the fan speed of 100rpm or under is detected for 30 second continuously under the outdoor unit fan control (with
the operation command of fan tap at Πspeed or higher), the compressor stops.
2) When the fan motor speed drops to 100rpm or under 5 times within 60 minutes and the compressor stops, it enters
the anomalous stop mode with E48 displayed on the remote controller.
(q) Anomalous stop by the compressor start stop
1)
2)
When it fails to shift to the compressor DC motor’s rotor position defection operation at 5 seconds after establishing
the compressor start condition, the compressor stops temporarily and restarts 3 minutes later.
If it fails to shift to the position detection operation again at second time, it judges the anomalous compressor start
and stops the compressor by the anomalous stop (E59).

Red and green lamps (LED) flash continuously on the outdoor unit control PCB.
Each of protection and error detection controls, excluding the low pressure control, anti-frost control and dewing
prevention control, is effective.
5) Outdoor unit fan is controlled as usual.
6) Electronic expansion valve is fully opened.
(b) Control ending conditions
Stop control is initiated depending on any of the following conditions.
1) Low pressure of 0.087MPa or lower is detected for 5 seconds continuously.
a) Red LED: Light, Green LED: Flashing, Remote controller: Displays stop.
b) It is possible to restart when the low pressure is 0.087MPa or higher.
c) Electronic expansion valve (cooling/heating) is kept fully open.
2) Stop by the error detection control
a) Red LED: Flashing, Green LED: Flashing
b) Restart is prohibited. To return to normal operation, reset the power supply.
c) Electronic expansion valve (cooling/heating) is left fully open.
3) When the cumulative operation time of compressor under the pump-down control becomes 5 minutes.
a) Red LED: OFF, Green LED: Flashing, Remote controller: Stop
b) It is possible to pump-down again.
c) Electronic expansion valve (cooling/heating) is left fully open.
Note (1) After the stop of compressor, close the operation valve at the gas side.
Caution: Since pressing the pump-down switch cancels communications with the indoor unit, the indoor unit and the
remote controller display “Transmission error – E5”. This is normal.

This PCB is a general PCB. Replace the PCB according to this instruction.
ԘReplace the PCB
(refer to right dwg.)
1. Unscrew terminal of the wiring(yellow/green) soldered to PCB from the box.
2. Cut the band that binds the wiring (red and blue) from connector CNW1 and CNW2, and the wiring (yellow/green) from PCB (T2/T3) . (Note 1)
㵘(However, do not cut the band that binds only the red and blue wirings.)
3. Replace the PCB only after all the wirings connected to the connector are removed.
4. Fix the board such that it will not pinch any of the wires.
5. Reconnect the wirings to the PCB. Wiring connector color should match with the color of connector of the PCB. (Note 2)
6. Let the wiring (red and blue) pass beneath the (yellow/green) wiring and bind together with band.
7. Screw back the terminal of wiring (yellow/green) from PCB(T1䋬T2/T3), that was removed in 1.
In that case, do not place the crimping part of the wiring under the PCB.
㵘 1): It might not be applicable on some models.
(Note
㵘 2): After replacing PCB, connection between capacitor assy and connector CNP is no longer needed.

Power transistor module terminal short circuit check procedure
Disconnect the compressor wiring, then conduct a short circuit check.
P-U, P-V, P-W
N-U, N-V, N-W
Check for a power transistor short circuit.
• When you do not have a diagnostic checker for judging if the inverter
is defective, measure between the terminals of the power transistor
parts, judge whether the power transistor is defective or not.
• Disconnect the compressor, then measure with the controller
incorporated.
Check between the P-N terminals.
Bring the tester probes in contact with the following
places on each te rminal.

Check of the outdoor unit grounding wire/earth leakage breaker
Run an independent grounding wire from the grounding screw
of outdoor unit to the grounding terminal on the distribution
panel. (Do not connect to another grounding wire.)
In order to prevent malfunction of the earth leakage breaker
itself, confirm that it is conformed to higher harmonic
regulation.
* Insulation resistance of compressor
4. Presumable cause
• Defective compressor
• Noise
• Immediately after installation or when the unit has been left
for long time without power supply, the insulation resistance
may drop to a few M because of refrigerant migrated in
the compressor.
When the earth breaker is activated at lower insulation
resistance, check the following points.
6 hours after power ON, check if the insulation resistance
recovers to normal.
When power ON, crankcase heater heat up compressor and
evaporate the refrigerant migrated in the compressor.
Check if the earth leakage breaker is conformed to higher
harmonic regulation or not.
Since the unit is equipped with inverter, it is necessary to use
components conformed to higher harmonic regulation in order
to prevent malfunction of earth leakage breaker.

4-way valve. This causes
a large change in pressure
which produces a blowing
sound. It may accompany
also the hissing sounds as
mentioned above. They are

After the start or stop of
heating operation or during
defrosting, abrupt changes
in temperature cause resin

Compressor startup failure
Yellow LED
Stays off or 4 times flash
5. Troubleshooting
All models
Diagnosis
Compressor does not start at all.
Neither noise nor vibration cannot be heard
Does
compressor
startup?
Countermeasure
Disconnect the outdoor fan motor
connector and try to startup
YES
Replace outdoor fan motor
NO
2. Error detection method
If it fails to change over to
the rotor detection operation
of compressor motor (If the
compressor speed cannot
increase 11Hz or higher)
Is power
supply voltage
OK?
NO
Check power supply
voltage
NO
Check refrigerant amount
and refrigerant circuit
NO
Repalce compressor
YES
Is
the pressure balance
at starting OK?
YES
Is the
insulation resistance
and coil resistance of
compressor OK ?
YES
3. Condition of Error displayed
If compressor fails to startup for
20 times (10 patterns x 2 times).
(It is availabel to reset by
remote controller after 3
minutes delay)
Is power transistor
module OK?
• Faulty outdoor fan motor
• Faulty inverter PCB
• Anomalous power supply
voltage
• Improper refrigerant amount
and refrigerant circuit
• Faulty compressor (Motor
bearing)
Defective inverter PCBª
Replace.
YES
Is
the output of inverter
checker OK ?
YES
4. Presumable cause
NO (Inverter PCB is defective)
Try to startup
several times
Does it start?
NO
Defective inverter PCBª
Replace.
Note: Several times restarting
may resolve it, because migrated
liquid refrigerant in the
compresser is discharged from
the compressor.
NO
Repalce compressor
Note: Insulation resistance
• The unit is left for long period without power supply or soon after installation, migrated liquid refrigerant may dissolve in the refrigerant oil in the compressor.
In such case insulation resistance decreases upto several M: or lower. If the electric leakage breaker is activated due to low insulation resistance,
check followings.
ΠCheck whehter the insulation resistance can recover or not, ater 6 hours has passed since power ON.
(By energize the crankcase heater, migrated liquid refrigerant in the refrigerant oil in compressor can be evaporated)

Method of trial operation
1. Trial operation can be performed by using
SW5-3.
2. Cooling trial operation will be performed
when SW5-4 is OFF, and heating trial
operation when SW5-4 is ON.
3. Be sure to turn OFF SW5-3 after the trial
operation is finished.
When this switch is turned ON, the outdoor
unit fan will run for 10 seconds in every 10
minutes, when outdoor temperature falls to
3㩩C or lower and the compressor is not
running when the unit is used in a very
snowy country, set this switch to ON.
The defrosting operation interval becomes
shorter by turning ON this switch.
This switch should be turned ON in the area
where outside temperature becomes below
the freezing point.

The specifications shown in the above table are for units without heaters. For units with heaters, refer
to the installation instructions or the construction instructions of the indoor unit.
Switchgear of Circuit breaker capacity which is calculated from MAX. over current should be chosen
along the regulations in each country.
The cable specifications are based on the assumption that a metal or plastic conduit is used with no
more than three cables contained in a conduit and a voltage drop is 2%. For an installation falling
outside of these conditions, please follow the internal cabling regulations. Adapt it to the regulation
in effect in each country.
Refer to installation manual or technical manual about usage of local setting switch.

The specifications shown in the above table are for units without heaters. For units with heaters, refer
to the installation instructions or the construction instructions of the indoor unit.
Switchgear of Circuit breaker capacity which is calculated from MAX. over current should be chosen
along the regulations in each country.
The cable specifications are based on the assumption that a metal or plastic conduit is used with no
more than three cables contained in a conduit and a voltage drop is 2%. For an installation falling
outside of these conditions, please follow the internal cabling regulations. Adapt it to the regulation
in effect in each country.

xAreas where the indoor unit can deliver hot and cold wind sufficiently. Suggest to the user to use
a circulator if the ceiling height is over 3m to avoid warm air being accumulated on the ceiling.
xAreas where there is enough space to install and service.
xAreas where it can be drained properly. Areas where drain pipe descending slope can be taken.
xAreas where there is no obstruction of airflow on both air return grille and air supply port.
xAreas where fire alarm will not be accidentally activated by the air conditioner.
xAreas where the supply air does not short-circuit.
xAreas where it is not influenced by draft air.
xAreas not exposed to direct sunlight.
xAreas where dew point is lower than around 28°C and relative humidity is lower than 80%.
This indoor unit is tested under the condition of JIS (Japan Industrial Standard) high humidity
condition and confirmed there is no problem. However, there is some risk of condensation drop
if the air conditioner is operated under the severer condition than mentioned above.
If there is a possibility to use it under such a condition, attach additional insulation of 10 to
20mm thick for entire surface of indoor unit, refrigeration pipe and drain pipe.
xAreas where TV and radio stays away more than 1m. (It could cause jamming and noise.)
xAreas where any items which will be damaged by getting wet are not placed such as food, table
wares, server, or medical equipment under the unit.
xAreas where there is no influence by the heat which cookware generates.
xAreas where not exposed to oil mist, powder and/or steam directly such as above fryer.
xAreas where lighting device such as fluorescent light or incandescent light doesn’t affect the
operation.
(A beam from lighting device sometimes affects the infrared receiver for the wireless remote
controller and the air conditioner might not work properly.)
N Check if the place where the air conditioner is installed can hold the weight of the unit. If it is not
able to hold, reinforce the structure with boards and beams strong enough to hold it. If the strength
is not enough, it could cause injury due to unit falling.
O If there are 2 units of wireless type, keep them away for more than 5m to avoid malfunction due to
cross communication.
P When plural indoor units are installed nearby, keep them away for more than 4m.

z Use the new refrigerant pipe.
When re-using the existing pipe system for R22 or R407C, pay attention to the following items.
xChange the flare nuts with the attached ones (JIS category 2), and reprocess the flare parts.
xDo not use thin-walled pipes.
z Use phosphorus deoxidized copper alloy seamless pipe (C1220T specified in JIS H3300) for
refrigeration pipe installation.
In addition, make sure there is no damage both inside and outside of the pipe, and no harmful
substances such as sulfur, oxide, dust or a contaminant stuck on the pipes.
z Do not use any refrigerant other than R410A.
Using other refrigerant except R410A (R22 etc.) may degrade inside refrigeration oil. And air getting
into refrigeration circuit may cause over-pressure and resultant it may result in bursting, etc.
z Store the copper pipes indoors and seal the both end of them until they are brazed in order to avoid
any dust, dirt or water getting into pipe. Otherwise it will cause degradation of refrigeration oil and
compressor breakdown, etc.
z Use special tools for R410 refrigerant.

2. Prepare a joint for connecting VP-20 pipe, adhere and connect the joint to the drain hose (the end
made of rigid PVC), and adhere and connect VP-20 pipe (prepare on site).
As for drain pipe, apply VP-20 made of rigid PVC which is on the market.
z Make sure that the adhesive will not get into the supplied drain hose.
It may cause the flexible part broken after the adhesive is dried up and gets rigid.
z Do not bend or make an excess offset on the drain hose as shown in the picture.
Bend or excess offset will cause drain leakage.
Over 20mm
Work procedure
1. Remove the flare nut and blind flanges on the pipe of the indoor unit.
Make sure to loosen the flare nut with holding the nut on pipe side with a spanner and giving
torque to the nut with another spanner in order to avoid unexpected stress to the copper pipe,
and then remove them.
(Gas may come out at this time, but it is not abnormal.)
z Pay attention whether the flare nut pops out. (as the indoor unit is sometimes pressured.)
2. Make a flare on liquid pipe and gas pipe, and connect the refrigeration pipes on the indoor unit.
Bend the pipe with as big radius as possible and do not bend the pipe repeatedly. In addition, do
not twist and crush the pipes.
Do a flare connection as follows:
z Make sure to loosen the flare nut with holding the nut on pipe side with a spanner and giving
torque to the nut with another spanner in order to avoid unexpected stress to the copper pipe,
and then remove them.
z When fastening the flare nut, align the refrigeration pipe with the center of flare nut, screw the
nut for 3-4 times by hand and then tighten it by spanner with the specified torque mentioned
in the table below. Make sure to hold the pipe on the indoor unit securely by a spanner when
tightening the nut in order to avoid unexpected stress on the copper pipe.
3. Cover the flare connection part of the indoor unit with attached insulation material after a gas
leakage inspection, and tighten both ends with attached straps.
z Make sure to insulate both gas pipes and liquid pipes completely.
Incomplete insulation may cause dew condensation or water dropping.
4. Refrigerant is charged in the outdoor unit.

Imperfection in draining may cause flood indoors and wetting the household goods etc.
z Do not put the drain pipe directly into the ditch where toxic gas such as sulfur, the other harmful and
inflammable gas is generated. Toxic gas would flow into the room and it would cause serious
damage to user’s health and safety (some poisoning or deficiency of oxygen). In addition, it may
cause corrosion of heat exchanger and bad smell.
z Connect the pipe securely to avoid water leakage from the joint.
z Insulate the pipe properly to avoid condensation drop.
z Check if the water can flow out properly from both the drain outlet on the indoor unit and the end of
the drain pipe after installation.
z Make sure to make descending slope of greater than 1/100 and do not make up-down bend and/or
trap in the midway. In addition, do not put air vent on the drain pipe. Check if water is drained
out properly from the pipe during commissioning. Also, keep sufficient space for inspection and
maintenance.

SAFETY PRECAUTIONS
This instruction manual illustrates the method of installing an indoor unit.
For electrical wiring work, please see instructions set out on the backside.
For outdoor unit installation and refrigerant piping, please refer to the installation manual that comes with your outdoor unit.
A wired remote control unit is supplied separately as an optional part.
– 140 –
z Execute proper grounding. Do not connect the ground wire to a gas pipe, water pipe, lightning rod or a telephone ground wire. Improper placement of
ground wires can result in electric shock.
z Do not put the drain pipe directly into the ditch where toxic gas such as sulfur is generated.
Toxic gas would flow into the room. Also, this may cause corrosion of indoor unit, and malfunction or refrigerant leakage.
z Be sure to bring back the packing material, form polystyrene, band and vinyl back etc., of the indoor and/or outdoor units after complete the installation
work, and then implement appropriate measures such as breaking them.
z When setting up or moving the location of the air conditioner, do not mix air etc. or anything other than the designated refrigerant (R410A) within the
refrigeration cycle.
Rupture and injury caused by abnormal high pressure can result from such mixing.
z Do not processing, splice the power cord, or share a socket with other power plugs.
This may cause fire or electric shock due to defecting contact, defecting insulation and over-current etc.
