20.1 GENERAL INFORMATION
20.1.1 Specific features
(1) Fuzzy control
(a) Response speed and stability are enhanced.
• The system automatically controls changes of return air temperature, set temperature and room temperature according to
the fuzzy control.
• The system response speed, can keep room temperature constant, and can adjust room temperature to set temperature
quickly.

(Return air thermistor)
E.E.V. pulse
(b) Elimination of temperature irregularity as the time of operation ON/OFF control
• The system finely controls the compressor to room temperature according to the temperature sensor, air conditions room
temperature consistently and improves cooling or heating feeling in each room (or minimize influence of shutdown in
other room).
(2) Super lynk system
• Non polar 2-core signal wires for indoor, outdoor units by means of the automatic polarity selection.
• In addition, the max. 48 units can be controlled with a pair of signal wires. The high speed transmission method same as
the computer network system [start up of 48 units can be completed within a few seconds by the determination of operation
mode and the start of operation].
• As separate power supplies for the indoor and the outdoor units are employed, a pair of 2 signal wires only are required for
the inter connecting wiring of indoor and outdoor units regardless of the number of units so that the installation work can
be simplified, the cost of wiring work can be curtailed and causes of wiring error can be minimized.

(3) Installation of automatic address setting function
• The address setting method are divided into three types according to wiring method: “Automatic Address Setting,”
“Remote control Address Setting.” and “Manual Address Setting.” In case of the Automatic Address Setting, no
address needs be set as usual.
(4) Connectable indoor capacity
Capacity from 50% to 130% is possible.
• FDCP2001HKXRE2
Number of connectable units: 1 to 8 units
Connectable capacity: 11000 ~ 29200 W
• FDCP2501HKXRE2
Number of connectable units : 1 to 8 units
Connectable capacity: 13200 ~ 37100 W
(5) Cooling opetation down to -5˚C outdoor temperature
(6) Indoor units are available with 9 capacities, in 9 types and 54 models.
● 9 capacities…22(0.8 HP), 28(1 HP), 36(1.25 HP), 45(1.6 HP), 56(22 HP), 71(2.5 HP), 90(3.2 HP), 112(4 HP) and 140(5 HP).
● 9 types…Ceiling recessed type(FDT), 2-way outlet ceiling recessed type(FDTW), 1-way outlet ceiling recessed type(FDTS),
Cassetteria type(FDR), Satellite ducted type(FDUM), Ceiling suspension type(FDE), Wall mounted type(FDK), Floor standing
exposed type(FDFL) and Floor standing hidden type(FDFU).
(7) Vertical blow or horizontal blow type can be selected for the outdoor unit.
horizontal blow
Standard
Vertical blow
Using an adapter
(Optional)
(8) Long piping design offeres One way piping length of 100 m
● Indoor and outdoor units can have a level difference of up to 50 m, with a one way piping length of up to 100 m. This is the topclass long piping design in the industry. A level difference of as much as 15 m between indoor units ensures that the system can
meet a wide variety of air conditioning requirements in any building.
(9) Layout free refrigerant piping
The branch type piping makes the system flexible enough to satisfy any layout plan on the floor or in a room.
(10) Improvement of serviceability
(a) Failures of indoor unit and outdoor units are shown on the liquid crystal display on the remote controller.
● Failures of indoor unit and outdoor units can be checked by remote controller.
(b) Easy checking of outdoor inspection LED.
● The LED can be checked without removing the service panel, and faulty units can be easily indentified out of several units.

(2) The values shown in the above table are common to both cooling and heating operations.
(c) Calculation of total operation characteristics
Since the operation characteristics of series Multi-KXR depend on combination of indoor unit, calculate the total operation
characteristics of the system by using the formulas below according to specifications of each indoor unit or outdoor unit.
1) Total power input
Total power input (kW) = Power input of outdoor unit + ∑ (Power input of indoor unit)
2) Total running current
Total running current (A) = Running current of outdoor unit + [∑ (Running current) × 2/3]
3) Total power factor
—
Total power factor (%) = [Total power input (W) / √ 3 × Total running current (A) × Power source] × 100
Total operation characteristics = Operation characteristic value of outdoor unit + Operation characteristic value of indoor unit
[Example]

Operation Voltage ········Indoor unit: 220 V, 50 Hz
Outdoor unit: 380 V, 50 Hz

(2) Automatic Operation
Once the [Auto] mode is selected by remote control, the operating mode is automatically selected according to the setting temperature
and the intake air temperature of the indoor unit and cooling or heating operation is performed. The determination is performed
when the thermostat has been in the OFF mode for 10 minutes or more continuously.
Notes (1) No determination is made if the mode setting is cooling, dehumidify or heating
and the cooling and heating thermostats have been in the off mode for 10 minutes
in the automatic operation mode.
(2) If set to automatic operation mode when the intake temperature is within ± 2 ˚C in
relation to the setting temperature, the same operation as the previous automatic

Heating operation
(a) Heating
• This is same as the cooling operation.
(b) Heating operation with thermostat OFF
1) Intermittent fan operation control
a) When the jumper wire J3 on the indoor PCB is shorted (installed at shipping),the fan of the unit of which the thermostat is
turned OFF during heating is operated in the Lo mode, and the indoor fan is turned OFF if the temperature rises 1˚C or more
than the return air temperature at the thermostat OFF.
b) Indoor fan OFF condition is maintained for 5 minutes and then the operation is reset at the Lo mode again. After operating
for 2 minutes in the Lo mode, return air temperature is checked and, if it is 1˚C or higher, the indoor fan is turned OFF or, if
it is not higher than 1˚C, the Lo mode operation continues.
Notes (1) If the heating thermostat has been turned OFF, the temperature is indicated on the remote controller only when the indoor fan is operated in the Lo
mode. When it is OFF, the room temperature at the end of Lo operation is indicated.
(2) If the operation is changed to the defrosting mode while the heating thermostat is at OFF or the thermostat is turned OFF during defrosting, the indoor
fan is turned OFF.
(3) Residual operation of heater is dominant over this control.
2) Fan stop control
a) If the jumper wire J3 on the indoor PCB (installed at shipment) is opened or the thermostat is turned OFF during heating
operation with the remote control sensor operating, the fan on the indoor unit is turned OFF.
(c) Hot start (Prevention of cold draft during heating)
If the required frequency in the room is other than 0 Hz at the start of heating operation, the indoor fan is controlled in
accordance with the temperature of indoor air heat exchanger (detected with ThI-R).
(Setting blow rate)
Stop
Indoor air heat exchanger temperature (˚C)
1034
Notes(1) When the hot start (the compressor is operating and the indoor unit fan is not operating at the setting
blow rate) is going on, the heating preparation is displayed (LCD on the remote controller).
(2) When the required frequency is other than 0 Hz, once the blower should start, it will not stop even
if the temperature drops below 20˚C.
(3) After the blower has been turned OFF for 7 minutes, the blower is operated regardless of the heat
exchanger temperature. (For 7 minutes after completion of defrosting during defrosting operation)
FDC-HKXR
(7) Value shift adjustment of room air temperature detection in heating
Under the standard specifications, the room temperature is adjusted at the setting temperature by controlling the indoor unit
capacity based on the setting temperature of thermostat and the suction air temperature.
However, where the unit is installed in the ceiling and warm air tends to stay around the ceiling, temperature in the living space may
not be adjusted at the setting temperature. In such occasion, it is recommended to change the setting of dip switch SW5-2, which is
found on the PCB of the indoor unit, to ON position so that the capacity control is tripped at +3 above the setting temperature of
thermostat and thus the heating feeling will improve.

Note (1) Refer to page 911 for position of SW
(8) Auto Swing Control (Excepted FDR, FDUM, FDFL, FDFU models)
(a) Have a louver motor to move the louvers up and down for the so called “AUTO SWING” function.
(b) The louver auto swing starts when the AUTO SWING switch is pressed once and stops when the AUTO SWING switch is
pressed again. The louver position is displayed on the LCD on the remote controller. During auto swing, the
position displayed on the LDC changes, but the positions of the louvers and the display are not coordinated. (The louvers
swing3-4 times per minute but the display changes once per second.)
(c) Stopping the louvers
When the AUTO SWING switch is pressed to stop the louver movement, the LCD louver-position display stops and the louvers
stop when they come to the position displayed on the LCD. There are four louver stop position on the LCD. (When jumper wire
J2 on the indoor unit printed circuit borad is cut, the louvers stop immediately at the AUTO SWING switch is pressed to stop
them and the LCD display changes to show this posiition. Refer to page 180 for position of jumper wire J2.
(d) Movement of louver when the power supply to the controller controlling 4 positions of the louver is switched on.
When power supply is switched on, the louver will automatically swing about 2 times (without operating remote controller).
This is an action for the microcomputer to confirm the louver position in order to input the cycle of the luver motor (LM) to the
microcomputer with the limit switch (LS) pushing the louver motor (LM). If the LS action is not input to the microcomputer, the
louver will stop within 1 minute after the power supply is switched on and will not move from then on.
(e) Keeping the louvers horizontal during heating
While HOT KEEP is displayed (during hot start operation or when the thermostat has turned off during heating operation),
the louvers stay in the horizontal position to prevent cold drafts, independent of the setting of the AUTO SWING switch (auto
swing or stop). The louver position display of LCD displays continuously the original position before this control operation.
When the HOT KEEP display goes out, both the louver and the LCD display return to their previous positions. (However,
after the power supply to the unit is switched on, the louvers swing two times as a check of the power source frequency,
regardless of the setting of the ON/OFF or AUTO SWING switches.)
(9) FILTER sign
When the operation time (time when the ON/OFF switch is turned to ON) is counted up at 600 hours (1), the filter sign on the remote
controller flickers.
This condition can be reset any time with the “Filter reset” switch. It is effective also to turn power OFF to reset.
Note (1) The function is invalidated if the jumper wire (J4) is opened. (See page 911 for the location of PCB.)
1035
FDC-HKXR
(10) Condensate pump motor (DM) control (Only FDT, FDTW, FDTS, FDR, FDUM models)
(a) Drain motor is started no sooner than the compressor is turned ON during cooling or dehumidifying operation. The drain motor
continues to operate for 2 minutes after the stop of unit operation, stop with the error stop, thermostat stop and at switching
from cooling or dehumidifying operation to blowing or heating operation. When there is any unit subjected to oil return
control, the drain motor is operated for 3 minutes at such occasion.
Note (1) Drain motor may be operated forcibly by turning ON the dip switch SW5-3 on the PCB. Turn the switch OFF to stop the drain motor.
(b) Overflow detection is always operable by means of the float switch regardless of operation modes. If the overflow is detected
(or when the float switch is disconnected or its wire is broken), operation is stopped with the error stopped. (FDT, FDTW,
FDTS, FDR and FDUM) If the overflow is detected while the drain motor is stopped, the drain motor is operated for 3 minutes
and then the overflow detection is performed to judge whether it is normal or not.

(i) Control A
a) If the float switch detects the draining, operation is stopped with the error stop (E9 is displayed) and operate the drain pump.
b) Float switch is checked 3 minutes later on the unit stopped by the error and, if the error persists still, the drain motor is left
at ON but, if the error has already been reset, the drain motor is turned OFF. E9 is displayed till the error is reset.
(ii) Control B
a) If the float switch detects the draining, the expansion valve is closed, the drain motor is turned ON for 3 minutes and, as 10
seconds elapses after the drain motor OFF, the float switch is checked. If the result is normal, the operation stops in the
normal way while, if it is not normal, E9 is displayed, the drain motor is turned ON and the operation stops with the error
stop with the expansion valve being closed completely. (It is left at ON while the draining is detected.)

(16) High pressure control
The high pressure control consists of the HP protection, HP-A control, HP-B control and LP control and the order of priority
among them is assigned as HP protection >HP-A > LP > HP-B down > HP-B up.
HP protection
Pressure switch [If 63H1: 3.24 open/2.65 close MPa (33 Open/27 close kgf/cm2) is actuated twice within 45 minutes, the
operation is stopped due to the error and the check and indication (Remote controller: E40, indoor LED-green; repeated flickers,
red: dark, outdoor LED-green; reperted flickers, red; 3 flickers) are performed. In case of initial operation, however, the
compressor is stopped and after a delay of 3 minutes it returns to the normal operation.]
HP-A control
• If the pressure switch (63H2) is actuated, the outdoor blower is opreated in the Hi mode (for the operations of patterns A1 to C1)
or stopped (for the operations of patterns C2 to E2) and, if it is still actuated 2 minutes after a drop of 10 Hz in the inverter
frequency, the frequency is dropped futher by 10 Hz. (Minimum frequency is specified at the partial load of 35 Hz.)
• Operation returns to the normal mode after operating with the frequency control at off(1) 6 minutes after the 63H2 having been reset.
Note (1): If the high pressure A control is released,the frequency is raised by 5 Hz and retained at the level for 3 minutes. The
frequency is then raised by 5 Hz at 3-minute intervals till it returns to the normal operation.

• LP control
If the pressure switch [63L: 1.96 close/2.75 open MPa (20 close/28 open kgf/cm2)] is actuated, the operation pattern is changed
by one step in the direction of A1 to E2 so as to raise the low level pressure by controlling the heat exchanger capacity.
• HP-B down control
If the pressure switch [63H3: 2.11 close/2.50 open MPa (21.5 close/25.5 open kgf/cm2)] is actuated, it enters the HP-B down
control and the operation pattern is changed by one step in the direction of E2 to A1 so as to lower the high level pressure by
controlling the heat exchanger capacity.
• HP-B up control
If the pressure switch [63H4: 1.86 close/1.67 open MPa (19.0 close/17.0 open kgf/cm2)] is actuated, it enters the HP-B up
control and the operation pattern is changed by one step in the direction of A1 to E2 so as to raise the high level pressure by

Remarks : Fuzzy control is not performed in test run operation.
(Operation is executed.) Other controls are effective.
(b) Expansion Valve Control for oil Return
After the compressor operated for 10 hours, and when the compressor is turned, stop the compressor to collect refrigerant
oil, turn off the thermostat, and fully open indoor unit expansion valves of FAN and adnormally stopped units one by one.
(Open expansion valves in the sequence that addresses were registered to outdoor units and not of the address number.
(c) High Pressure Control in Heating Operation
When (63H2) [2.84 close/2.26 open MPa (29.0 close/23.0 open kgf/cm2)] operates, the compressor revolution decrease 10
Hz, and outdoor unit fan stops preventing pressure increase. Frequency control is canceled after 6 minutes from reset of
63H2, then the compressor returns to the normal operation.
Note (1) Detail of Frequency Control Canceling Operation
When a high pressure control is canceled, the frequency increases 5 Hz, and the frequency is retained for 3 minutes. The
frequency increases 5 Hz every 3 minutes to the normal operation.
(d) Discharge gas Temperature Control (All Operation Modes)
When the discharge gas temperature (discharge gas thermistor : ThO-D) increases above the set point, the temperature (detected
with ThO-D) is controlled by opening and closing the liquid bypass solenoid valve (SV1) and by lowering the frequency.
Note (1) ThO-D > 115°C .......SV1-Open [ThO-D < 108°C Closes]
The expansion valve of operating indoor unit open 5% approx.
ThO-D > 120°C .......The frequency is lowered 10Hz each time at intervals of 2 minutes (Lower Limit: 35 Hz of the
full load or a hot gas bypass.) (ThO-D = < 115°C are canceled)
ThO-D > 130°C.......abnormal stop
[The operation can be resumed at a temperature bellow 90°C]
(e) Compressor Control at the during of startup
(i)
Inrush Current the compressor with 5Hz to the starting.
Also, at the time of startup, fully open the expansion valve of the indoor unit in the operator cab for 4 minutes.
(ii) Protective Start of Compressor
When the inverter starts, the compressor start under protection.
Operate with hot gas bypass up to 35 Hz after the start, operate with full loads of 60 Hz for 15 seconds, then operate
with the decision frequency. When the frequency is higher than 65 Hz, they operate with 65 Hz for one minute 45
seconds after the start. But when the compressor starts first time after the power is turned on, and when the compressor
starts after stop for more than 6 hours, it increases the frequency 5 Hz each minute for 13 minutes.

(g) Open-phase Protection
When the T-phase voltage of the secondary side of 52C is 0V, an abnormal stop will occur and the inspection displays
(Remote controller : E34, indoor unit green LED : Continuous flashing, red LED : OFF, outdoor unit green LED : red LED
: 2 times flash) will appear.
(h) Current Safe Control
The operation corrent is automatically controlled.
When the operation current at the converter inlet increases, the frequency is lowered 5 Hz by 5 Hz so that the operation
current does not increase above the set point.
Lower limit frequency: Hot gas bypass 35 Hz
1) Retain the operations with hot gas bypass of 35 Hz for 3 minutes, and when it is foud to be the current safe value, stop the
inverter, operate them with hot gas bypass 3minutes later for 3 minutes. When the frequency is below the current safe
value, operate them with full loads of 35 Hz, cancel the frequency control to bring them back to the normal operation.
2) When the decision frequency under the fuzzy control get lower than the current safe frequency during a current safe
control, bring them back to the normal operation. When the current value comes to the current cancel value during a
current safe control, retain the frequency for 3 minutes, then cancel the frequency control.
(i) Current Cut Control
This control aims to prevent over current in the converter. When the current increases above the set point, stop the inverter
immediately, then let is reset by itself 3 minutes later. After the self-reset, start the inverter with 35 Hz, and increase the
frequency 5 Hz every 3 minutes to let it return to the fuzzy indication frequency. When the current is cut four times in 15
minutes, turn off 52C bring it to an abnomal stop and the inspection displays (Remote controller : E42, indoor unit green LED
: Continuous flashing, red LED : OFF, outdoor green LED : Continuous flashing,and red LED : 1 time flash will appear.
(j) Protection of Power Transistor from Overheat
When the temperature of the power transistor increases to the set temperature, stop the inverter immediately and let is reset
by itself 3 minutes later. If the power transistor is overheated again within 2 hours, turn off 52C, bring it to an abnormal
stop and the inspection displays (Remote controller : E41, indoor unit green LED : Continuous flashing, red LED : OFF,
outdoor unit green LED : Continuous flashing, red LED : 4 times flash) will appear.

stop and the inspection displays (Remote controller : E41, indoor unit green LED : Continuous flashing, red LED : OFF,
outdoor unit green LED : Continuous flashing, red LED : 4 times flash) will appear.
(l) Protection of Number of Connected indoor Units
When the number of connected indoor units exceeds the quantities shown in the table below, they will come to an abnormal
stop, and the inspection displays (Remote controller E43, indoor unit green LED : Continuous flashing, red LED : OFF,
outdoor unit green LED : Continuous flashing, red LED : 7 times flash) will appear.

(m) Frost prevention during cooling
To prevent frost during a cooling operation, check temperature (to be detected with ThI-R) of the indoor unit heat exchanger
and lower the frequency of indoor unit (opening of expansion valve) when the temperature drops below 3°C.
When the heat exchanger temperature is below 2°C for more than 2 minutes, turn off the thermostat and start a ventilating
operation. If the heat exchanger temperature rises above 16°C after the thermostat is turned off, reset it to a cooling operation.
But this operation shall not be executed for 10 minutes after the thermostat is turned on.
Also when temperatures of standing units have been below 2°C for an hour in succession, turn off the compressor for 3
minutes.

20.5 APPLICATION DATA
SAFETY PRECAUTIONS
• Please read these “Safety Precautios” first then accurately execute the installation work.
• Though the precautionary points indicated herein are divided under two headings,
WARNING and
CAUTION , those
points which are related to the strong possibility of an installation done in error resulting in death or serious injury are listed in
the
WARNING section. However, there is also a possibility of serious consequences in relationship to the points listed in
the
CAUTION section as well.
In either case, important safety related information is indicated, so by all means, properly observe all that is mentioned.
• After completing the installation, along with confirming that no abnormalities were seen from the operation tests, please explain
operating methods as well as maintenance methods to the user (customer) of this equipment, based on the owner’s manual.
Moreover, ask the customer to keep this sheet together with the owner’s manual.
WARNING
• This system should be applied to places of office, restautant, residence and the like. Application to
inferior environment such as engineering shop could cause equipment malfunction.
• Please entrust installation to either the company which sold you the equipment or to a professional
contractor. Defects from improper installations can be the cause of water leakage, electric shocks
and fires.
• Execute the installation accurately, based on following the installation manual. Again, improper installations can result in water leakage, electric shocks and fires.
• When a large air-conditioning system is installed to a small room, it is necessary to have a prior
planned countermeasure for the rare case of a refrigerant leakage, to prevent the exceeding of threshold concentration.
In regards to preparing this countermeasure, consult with the company from which you purchased the
equipment, and make the installation accordingly. In the rare event that a refrigetant leakage and
exceeding of threshold concentration does occur, there is the danger of a resullant oxygen deficiency
accident.
• For installation, confirm that the installation site can sufficiently support heavy weight. When strength
is insufficient, injury can result from a falling of the unit.
• Execute the prescribed installation construction to prepare for earthquakes and the strong winds of
typhoons and hurricanes, etc. Improper installations can result in accidents due to a violent falling
over of the unit.
• For electrical work, please see that a licensed electrician executes the work while followig the safety
standards related to electrical equipment, and local requlations as well as the installation instructions,
and that only exclusive use circuits are used.
Insufficient power source circuit capacity and defective installment execution can be the cause of
electric shocks and fires.
• Accurately connect wiring using the proper cable, and insure that the external force of the cable is not
conducted to the terminal connection part, through properly securing it. Improper connection or securing can result in heat generation or fire.
• Take care that wiring does not rise upward, and accurately install the lid/service panel. Its improper
installation can also result in heat generation or fire.
• When setting up or moving the location of the air-conditioner, do not mix air etc. or anything other
than the designated refrigerant within the refrigeration cycle.
• Always use accessory parts and authorized parts for installation construction. Using parts not authorized by this company can result in water leakage, electric shock, fire and refrigerant leakage.
CAUTION
• 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.
• The installation of an earth leakage breaker is necessary depending on the established location of the
unit. Not installing an earth leakage breaker may reslut in electric shock.
• Do not install the unit where there is a concern about leakage of combustible gas.
The rare event of leaked gas collecting around the unit could result in an outbreak of fire.
• For the drain pipe, follow the installation manual to insure that it allows proper drainage and thermally
insulate it to prevent condensation. Inadequate plumbing can result in water leakage and water damage to interior items.

20.5.4 Refrigerant piping
(1) Precautions no refrigerant piping work for prevention against compressor lock
Compressor trouble including lock and motor burn-out is due to faulty parts but mainly concerned in installation and refrigerant
piping conditions, The precautions for refrigerant piping are as belows.
(a) Be sure to perform brazing while flowing nitrogen.
1)
Without flowing nitrogen gas, a lot of oxide film (CU2O) is generated. In particular, in case of for building with many
2)
A foreign material (oxide film) causes clogging of the capillary tube or expansion valve, leading to non-cooling (non-
brazed portions, oxide film is so much generated that this causes a fatal failure in the air conditioning system.
heating), abnormal discharge temperature, compressor lock due to a faulty oil return. In some cases, a lot of foreign
materials block the oil return hole of the accumulator, thereby causing a compressor lock. (This lock trouble may occur
repeatedly 2 or 3 times.)
(b) Don’t admit water (waterdrops, condensation) into the piping.
1)
Use a copper piping that is free from water (waterdrops,
condensation).
2)
Don’t perform refrigerant piping work while it rains.
3)
To suspend outdoor piping work, perform curing to prevent
water admission.

generation resulting from reaction on refrigerating
machine oil
(c) Don’t admit dust or foreign particles in the pipe.
Various foreign particles are included in air conditioners that caused trouble. Be careful about them.
(Concrete fragments, cement, sand, paint, metal powder (copper refuse after deburring, etc.), etc.
(d) Adopt the specified dimensions for pipes.
Too thick:
Improper charge volume
Compressor lock
Faulty oil return (insufficient gas flow rate)
Too long (L):
Overcharge
Liquid back
Compressor lock
Faulty oil return
(e) Be sure to support the refrigerant piping with support fittings.
1)
The pipe vibrates and expands/shinks during operation. Without proper supports, a load is concentrated partially and
cracks and collapse occur on the piping, thereby causing a unit failure.
2)
A support should be provided at intervals of 2 or 3 m so as not to partially concentrate a load.

(4) Heat insulation
(i) There is a need to insulate both gas and liquid piping with heat insulation for protection against heat and
condensation.
1) Always use heat insulation to prevent condensation on the gas piping from becoming drain water and
causing leakage during cooling and to prevent people from being burned by the high temperature of the
surface of the gas piping as discharge gas flows through it.
2) Use heat insulation (pipe cover) on the flare connection sections of the indoor unit.
(Insulate both the gas and liquid piping.)
3) Insulate both the gas and liquid piping. Apply the insulation so that is tight against the piping and free of
gaps. Route the connecting wires with the insulation and wrap the entire bundle with exterior tape.

Insulation
Use insulation material with good resistance heat properties (120 ˚C or more).
(5) Air-tight test
(a)
When conducting an air-tight test of local piping, connect the piping to the check joint of the evacuating pipe connected to
the gas side service valve, and keep the service valve closed. The air-tight test pressure shall be 3.23MPa(33 kgf/cm2.)
(b)
To conduct the test, pressurize the check joint of evacuating pipe by nitrogen gas as shown below. The local piping
including indoor units can be tested as for airtightness.
(6) Evacuating
Evacuating can be completed faster by evacuating both the check joint on the liquid side service valve and the check joint of the
evacuating gas pipe (accessory) connected to the gas side operation valve at the same time. (Of course, evacuating is possible
even through the liquid side check joint only.)

Additional refrigerant
Charge is not required
Notes (1) When the refrigerant piping length exceeds the length that additional refrigerant charge is not required, charge
additional refrigerant based on to calculated amount of refrigerant per unit piping length.
(2) The unit is holding charge type that all of the refrigerant is charged in the outdoor unit and in the indoor unit only
a small amount of refrigerant is filled for prevention of the air entry.
Calculation of amount of refrigerant to be charged in local piping
The amount refrigerant additionally charged in local piping depends on connection pipe size but not on indoor unit type.
[Amount of refrigerant to be charged in the local piping = Actual length of liquid pipe × Amount of
refrigerant additionally charged per meter of liquid pipe]
[Example] Amount of refrigerant additionally changed = (I1 × 0.12) + (I2 × 0.06) + (I3 × 0.03)
I1 : Overall length (m) of φ12.7 liquid pipe
I2 : Overall length (m) of φ9.52 liquid pipe
I3 : Overall length (m) of φ6.35 liquid pipe
Following precautions must be observed when the model is adapted to R407C.
(1) Tools and related components should be changed when handling a different kind of refrigerant in order to prevent mixing of different oils.
Gauge manifold and charge hose, particularly, should never be used after using them for R22.
(2) Charge cylinder should not be used. Otherwise, the refrigerant composition may change when charging R407C into the cylinder.
(3) Refrigerant should be charged in the liquid phase from the container. Charging the refrigerant in the gaseous phase could change the
refrigerant composition substantially.
(4) Volume of refrigerant to be taken out in the liquid phase from the container should be up to 90% of necessary quantity (in weight percent)
as a standard.
(5) Refrigerant should not be replenished even if a leakage is discovered because it could change the refrigerant composition substantially.
When a leakage is discovered, replace with new refrigerant in the specified volume. However, it could be replenished temporarily in case of
an emergency.

(a) Use separate power supplies for the outdoor and indoor units respectiveliy (Standard specification)
(b) Signal wiring (for indoor and outdoor units)
Double-core cable with a diameter 0.75 to 2 mm2 should be used for the signal wires.
Never make the indoor and outdoor connecting signal line use “co-axial cable” or “strand” with the
power wiring for indoor and outdoor unit and other ower line.
(Never use a multiconductor wire together with power line. It may cause erroneous operation.)
Do not connect high voltage wires 220/240 V or 380/415 V to signal wires. as these wires are DC 5V. Signal wires
should be connected so that the terminal Nos. conform with each other for between outdoor and between indoor units.
However, they will work properly if different polarities are connected.
(Connect (A) and (A), (B)and (B).)
Do not strand or run the remote control cord with power line, electric line, etc.
The total length of the signal wires Should be 1000m or less.

NO
Cause is accidental (noise, etc.)
and the unit is normal.
YES
Check of error code
Errors due to external noise, etc.
Error code may be displayed or the error may not be displayed normally even if the controller is normal because of external noise
source(1) or joined or parallel arrangement of power cables and signal wires. It is because the wire of remote controller, wired
remote controller signal wires for multiple units or the network signal wires may be influenced by external noises whitch are
judged as signals by the microcomputer whitch reacts mistakenly.
When there is any noise source, it is necessary to the shield wire for the remote controller and signal wires.
Note (1) High frequency medical machine, rectifier motor application device, thyristor, broadcast transmission tower, power
transmission line, power line of electric train, automatic door motor, elevator (voltage drop), wireless telephone, high
voltage power distribution line, computer, personal compouter and their cables.
There do not necessarily always cause problems but they can be a source of electrical noise.

Reference Effect of noise
• When noises inturude into the remote controller.
Abnormal or irregular display such as the flashing of irrelevant display (lamp) (for example, LEDs of cooling and heating
illuminated simultaneously or the like) is observed even if the remote controller is not operated or the remote controller and,
as the result, the operation of units may be disabled or similar abnormal phenomenons are observed.
• When noises intruded into the microcomputer of printed circuit board; State of operation becomes abnormal such as the units
perform irregular operation while the remote controller is not operated, the operation cannot be stopped with the remote
controller, etc.
Electro magnetic noise prevention(example)
• Cover the entire surface of control box or
the inside of unit cover with the cover foil
or cover the enitre unit with a wire net.
Use the shield or
twist pair wires

l1
Put in a steel case Remote controller
Separate from cutting machine as for as
possible. This is very effective because
the effect of noise is in inverse
proportion to 1.5 times of distance.
•Insert in a steel pipe to shield.
Power
cable
Unless it has a sufficient current
capacity, mini split current drops
momentarily at the start/stop of
cutting machine.
Distribution
board
Avoid supply from the same
distribution board to prevent troubles
by the power source propagation.
Install the line filter at the power
supply of cutting machine of mini split
(Positive grounding is necessary.)
(b) Eroor diagnosis procedures at the indoor unit side
The error diagnosis for indoor units is the same as for the Multi KX Series. For details, please refer to the section for the KX
Series found on pages 910 to 917.
(c) Error diagnosis procedures at the outdoor unit side
At the error diagnosis related to the outdoor unit, check at first the error code of remote controller and the illumination patterns of
norma l and inspection display lamps in the same manner as the case of indoor unit.
Then estimate the outline, the cause and the location of error based on the pattern and proceed to the inspection and repair. Since
the self diagnosis function by means of the microcomputers of indoor/outdoor units provide the judgement of error of
microcomputers them selves irregularity power supply line, overload, etc. caused by the installation space, inadequate volume of
refrigerant etc., the location and cause of trouble will be discovered without difficulty.
In addition, the display lamps error code of indoor/outdoor units is kept flashing, (except when the power supply is
interrupted)after the irregularity is automatically recovered to give irregularity information to the service presonnel. If any mode
of higher priority than the error retained in memory occurs after the reset of error, it is switched to that mode and saved in the
memory.

(2) Check the wirng between the power transistor
module and inverter PCB. If it is normal,
judge that the power transistor module is
fauly.
(3) The 52C turns on, then turn off in 10 seconds.
This is repeated 3 times and E45 is indicated.
(iii) Cooling(heating) effectiveness is low. (Check the refrigerant volume and refrigerating cycle in addition to
the following items.)
1) For low cooling effectiveness
a) Check if the protective function operates with the result that the operating frequency of the compressor goes below the
specified frequency value.
Note (1) When the current safe control and discharge temperature control are activated, the frequency is lowered.
b) Check if the operation of the indoor unit expansion valve is normal or there is no clogging.
c) Check if the anti-frost function operates.
Procedure for Checking Indoor unit Electronic Expansion Valve Operation
Check the indoor unit controller to expansion valve output according to the following procedure.
Measure the voltage value appearing at the pin on the control side of the expansion valve (SM) connector CnA (white, 6P
(5-conductor), and also the duration of voltage application.
Orange~Gray, Yellow~Gray
Approx DC5V(2) for 15 seconds(1) when the power supply is turned on.
Red ~Gray, Black ~Gray
Notes (1) After the power supply is turned on, the voltage is about 5 V for 8 seconds, decreases momentarily, and then is kept
at about 5 V for about 7 seconds.
(2) When a measurement is made with a digital multitester, voltages of 6-3 V are output in sequence.
}
When the above duration and voltage value can be verified, the indoor unit controller is normal.
If the expansion valve does not operate (no operating sound is produced) though a voltage is provided, the expansion valve is
faulty.
By changing the setting of the thermostat, the expansion valve is operated in about 20 seconds. Like the above, a DC voltage
of about 5 V can be checked at the connector CnA.
2) Low heating effectiveness.
a) Check if the operating frequency of the compressor is lowered below the specified frequecny because the protective
function is activated.
Note (1) When high pressure control [63H2 ON: 2.26 open/2.84 closeMPa (23 open/29 close kgf/cm2)], current safe
control and discherge temperature control is exerted, the frequecny is lowered.
b) Check if the operation of the outdoor unit expansion valve is normal, or if any clogging occurs.
