produced.
• When installing in small rooms, take prevention measures not to exceed
the density limit of refrigerant in the event of leakage.
Consult the expert about prevention measures. If the density of refrigerant
exceeds the limit in the event of leakage, lack of oxygen can occur, which
can cause serious accidents.
• After completed installation, check that no refrigerant leaks from the system.
If refrigerant leaks into the room and comes into contact with an oven or
other hot surface, poisonous gas is produced.
• Use the prescribed pipes, flare nuts and tools for R410A.
Using existing parts (for R22 or R407C) can cause the unit failure and serious accidents due to burst of the refrigerant circuit.
• Tighten the flare nut by torque wrench with specified method.
If the flare nut were tightened with excess torque, this may cause burst and
refrigerant leakage after a long period.
• Do not open the operation valves for liquid line and gas line until completed refrigerant piping work, air tightness test and evacuation.
If the compressor is operated in state of opening operation valves before
completed connection of refrigerant piping work, air can be sucked into refrigerant circuit, which can cause bust or personal injury due to anomalously
high pressure in the refrigerant.
• The electrical installation must be carried out by the qualified electrician in accordance with “the norm for electrical work” and “national
wiring regulation”, and the system must be connected to the dedicated
circuit.
Power supply with insufficient capacity and incorrect function done by improper work can cause electric shocks and fire.
• Be sure to shut off the power before starting electrical work.
Failure to shut off the power can cause electric shocks, unit failure or incorrect function of equipment.
• Be sure to use the cables conformed to safety standard and cable
ampacity for power distribution work.
Unconformable cables can cause electric leak, anomalous heat production or
fire.
• This appliance must be connected to main power supply by means of a

(d) Current safe
1)
Purpose: Current is controlled not to exceed the upper limit of the setting operation current.
2)
Detail of operation: Input current to the converter is monitored with the current sensor fixed on the printed circuit board of the outdoor unit and, if the operation current value reaches the limiting current value, the compressor
command speed is reduced.
If the mechanism is actuated when the speed of compressor command is less than 30 rps, the
compressor is stopped immediately. Operation starts again after a delay time of 3 minutes.
(e) Current cut
1)
Purpose: Inverter is protected from overcurrent.
2)
Detail of operation: Output current from the converter is monitored with a shunt resistor and, if the current exceeds the
setting value, the compressor is stopped immediately. Operation starts again after a delay time of
3 minutes.
(f) Outdoor unit failure
This is a function for determining when there is trouble with the outdoor unit during air conditioning.
The compressor is stopped if any one of the following in item 1), 2) is satisfied. Once the unit is stopped by this function, it is not restarted.
1) When the input current is measured at 1 A or less for 3 continuous minutes or more.
2) If the compressor command sends a 0 rps signal to the indoor unit 3 times or more within 20 minutes of the power being
turned on.
(g) Inching prevention
When the compressor goes into the thermo operation within 10(5) minutes since operation start or becomes various dehumidifying
operations, the operation is continued with the lower limit speed forcibly.
Note (1) Values in ( ) are for the model 18.
(h) Indoor fan motor protection
When the air conditioner is operating and the indoor fan motor is turned ON, if the indoor fan motor has operated at 300 rpm or under for more than 30 seconds, the unit enters first in the stop mode and then stops the entire system.
(i)
Serial signal transmission error protection
1) Purpose: Prevents malfunction resulting from error on the indoor ↔ outdoor signals.
2) Detail of operation
a) When the outdoor unit controller cannot receive signals from the indoor unit
If the compressor is operating and a serial signal cannot be received from the indoor control with outdoor control having serial signals continuously for 1 minute and 55 seconds, the compressor is stopped.
After the compressor has been stopped, it will be restarted after the compressor start delay if a serial signal can be received again from the indoor control.
b) When the indoor unit controller cannot receive signals from the outdoor unit
i) If the outdoor unit inverter signals cannot be received for 10 seconds continuously during the transfer error check
at the first time after turning on the power supply, the compressor is stopped immediately.
ii) If the outdoor unit inverter signals cannot be received for 1 minute and 50 seconds continuously, it tries to restart
two time but stops the operation at third failure of restart.
(j) Rotor lock
If the motor for the compressor does not turn after it has been started, it is determined that a compressor lock has occurred and
the compressor is stopped.
(k) Outdoor fan motor protection
If the outdoor fan motor has operated at 75rpm or under for more than 30 seconds, the compressor and fan motor are stopped.

8. MAINTENANCE DATA
(1) Cautions
(a) If you are disassembling and checking an air conditioner, be sure to turn off the power before beginning. When working on
indoor units, let the unit sit for about 1 minute after turning off the power before you begin work. When working on an outdoor
unit, there may be an electrical charge applied to the main circuit (electrolytic condenser), so begin work only after discharging this electrical charge (to DC 10 V or lower).
(b) When taking out printed circuit boards, be sure to do so without exerting force on the circuit boards or package components.
(c) When disconnecting and connecting connectors, take hold of the connector housing and do not pull on the lead wires.
(2) Items to check before troubleshooting
(a) Have you thoroughly investigated the details of the trouble which the customer is complaining about?
(b) Is the air conditioner running? Is it displaying any self-diagnosis information?
(c) Is a power supply with the correct voltage connected?
(d) Are the control lines connecting the indoor and outdoor units wired correctly and connected securely?
(e) Is the outdoor unit’s service valve open?
(3) Troubleshooting procedure (If the air conditioner does not run at all)
If the air conditioner does not run at all, diagnose the trouble using the following troubleshooting procedure. If the air conditioner is running but breaks down, proceed to troubleshooting step (4).
Important When all the following conditions are met, we say that the air conditioner will not run at all.
(a) The RUN light does not light up.
(b) The flaps do not open.
(c) The indoor unit fan motors do not run.
(d) The self-diagnosis display does not function.

(6) Service mode (Trouble mode access function)
This air conditioner is capable of recording error displays and protective stops (service data) which have occurred in the past. If
self-diagnosis displays cannot be confirmed, it is possible to get a grasp of the conditions at the time trouble occurred by checking
these service data.
(a) Explanation of terms
Term
Explanation
Service mode
The service mode is the mode where service data are displayed by flashing of the display lights
when the operations in item (b) below are performed with the indoor controller.
Service data
These are the contents of error displays and protective stops which occurred in the past in the air
conditioner system. Error display contents and protective stop data from past anomalous
operations of the air conditioner system are saved in the indoor unit controller’s non-volatile
memory (memory which is not erased when the power goes off). There are two types of data,
self-diagnosis data and stop data, described below.
Self-diagnosis data
These are the data which display the reason why a stop occurred when an error display (selfdiagnosis display) occurred in an indoor unit. Data are recorded for up to previous occurrences.
Data which are older than the th previous occurrence are erased.
In addition, data on the temperature of each sensor (room temperature, indoor heat exchanger,
outdoor heat exchanger, outdoor air temperature, discharge pipe), remote controller information
(operation switching, fan speed switching) are recorded when trouble occurs, so more detailed
information can be checked.
Stop data
These are the data which display the reason by a stop occurred when the air conditioning system
performed protective stops, etc. in the past. Even if stop data alone are generated, the system
restarts automatically. (After executing the stop mode while the display is normal, the system
restarts automatically.) Data for up to 0 previous occasions are stored. Data older than the 0th
previous occasion are erased.
( Important) In cases where transient stop data only are generated, the air conditioner system
may still be normal. However, if the same protective stop occurs frequently ( or
more times), it could lead to customer complaints.
(b) Service mode display procedure
Start
Turn off the air conditioner’s power once, then
wait 1 minute or longer.
Turn the air conditioner’s power on again while
pressing the unit ON/OFF button.
NO (*)
*1:If the buzzer does not sound no matter how
many times you repeat the operation, the
unit ON/OFF button may be faulty.
Did a buzzer located in
the indoor unit sound?
YES
Within 1 minute after turning the air conditioner’s power on, signals will be sent from the
remote controller (*2)
*2:Set the remote control’s settings on “Cooling
operation,” “Fan speed: MED” and “Set temperature: 21ºC.”
Count the number of times the RUN light and
TIMER light flash (*3), and check the contents of the
error, etc. from the table. (See pages 35 and 36.)
Are other data displayed?
NO
YES
Change the remote controller settings based on
the instructions in the table (*4). (See page 38.)
-
37 -
Turn off the air conditioner’s power to terminate the
service mode. If you are going to turn the power on
again, wait 1 minute or longer after turning it off.
'12 • SRK-T-124
*3:To count the number of flashes in the service mode, count the number of flashes after the light lights up for 1.5 second
initially (start signal). (The time that the light lights up for 1.5 second (start signal) is not counted in the number of
flashes.)
• In the case of current safe (heating CT1) (example: stop code “32”)
The RUN light (10’s digit) flashes 3 times and the TIMER light (1’s digit) flashes 2 times.
3 × 10 + 2 × 1 = 32 → From the table, read the instructions for error code 32, “current safe (heating CT1).

(a) Inspection of electronic expansion valve
Electronic expansion valve operates for approx. 10 seconds after the power on, in order to determine its aperture. Check the
operating sound and voltage during the period of time. (Voltage cannot be checked during operation in which only the aperture
change occurs.)
1) If it is heard the sound of operating electronic expansion valve, it is almost normal.
2) If the operating sound is not heard, check the output voltage.

Approx. 5 V is detected for 10 seconds after the power on.
If voltage is detected, the outdoor PCB is normal.
If the expansion valve does not operate (no operating sound) while voltage is detected, the expansion valve is defective.
• Inspection of electronic expansion valve as a separate unit
Measure the resistance between terminals with an analog tester.

(b) Outdoor unit fan motor check procedure
• When the outdoor unit fan motor error is detected, diagnose which of the outdoor unit fan motor or outdoor PCB is defective.
• Diagnose this only after confirming that the indoor unit is normal.
(1) Outdoor PCB output check
1) Turn off the power.
2) Disconnect the outdoor unit fan motor connector CNFAN.
3)When the indoor unit is operated by inserting the power supply plug and pressing (ON) the backup switch for more
than 5 seconds, if the voltage of pin No. ② in the following figure is output for 30 seconds at 20 seconds after
turning “ON” the backup switch, the outdoor PCB is normal but the fan motor is defective.
If the voltage is not detected, the outdoor PCB is defective but the fan motor is normal.
Note (1) The voltage is output 3 times repeatedly. If it is not detected, the indoor unit displays the error message.
