Note (1) This LED isinstalled on models SRC40-60 only.
1. Applicable model
Model s SRC40-60
2. Error detection method
Anomalous stop
Reset
53(51) 63(56)
Outdoor heat exchanger temperature (°C)
Note(1) Values in ( ) are appli-
cable when outdoor
temperature (TH2) is
lower than 32°C
3. Condition of error displayed
When anomalous outdoor heat
exchanger temperature occurs
5 times within 60 minutes or
63(56)°C or higher continues
for 10 minutes, including the
compressor stop.
4. Presumable cause
• Defective outdoor heat
exchanger temperature sensor
• Defective outdoor unit PCB
• Indoor, outdoor unit
installation spaces
• Short-circuit of air on indoor,
outdoor units
• Fouling, clogging of heat
exchanger
• Excessive refrigerant quantity

5. Troubleshooting
Diagnosis
Are normal
the characteristics of
outdoor heat exchanger
temperature sensor
normal?
YES
Is the
unit operating in
the state of cooling
overload?
NO
Is the high
pressure control
normal
YES
Is
the temperature
(measured actually) at
direction of error
correct?
* For the contents of control, refer to the protective control by controlling
compressor rotation speed and cooling high pressure protective control of
microcomputer control function for corresponding models.

Countermeasure
Replace outdoor heat
exchanger temperature
sensor.
Check unit side.
• Isn't the air circulation
of outdoor unit short-
circuited?
• Are installation spaces
adequate?
• Isn't there any fouling
or clogging on heat
exchanger?
Control operation check*.
