1. Error
Code
High pressure fault 2 (Outdoor unit)
2. Error
definition and error detection method
If the pressure of 0.098MPa [14psi] or lower is registered on the pressure sensor immediately before start-up, it will trigger an
abnormal stop, and error code "1302" will be displayed.
3. Cause, check method and remedy
1. Error
Code
Refrigerant overcharge
2. Error
definition and error detection method
An error can be detected by the discharge temperature superheat.
1) If the formula "TdSH 10°C [18°F]" is satisfied during operation (first detection), the outdoor unit stops, goes into the 3-minute
restart mode, and starts up in three minutes.
2) If the formula "TdSH 10°C [18°F]" is satisfied again within 30 minutes of the fifth stoppage of the outdoor unit (sixth detec-
tion), the unit comes to an abnormal stop, and the error code "1500" appears.
3) If the formula "TdSH 10°C [18°F]" is satisfied 30 minutes or more after the first stoppage of the outdoor unit, the same se-
quence as Item "1 above (first detection) is followed.
4) For 30 minutes after the stop of the outdoor unit, preliminary errors will be displayed on the LED display.
3. Cause, check method and remedy
1302
Cause
Check method and remedy
(1)
Inner pressure drop due to a leakage.
Refer to the page on the troubleshooting of the high
pressure sensor.(page 224)
(2)
Pressure sensor failure
(3)
Shorted-circuited pressure sensor cable due to torn
outer rubber
(4)
A pin on the male connector on the pressure sensor
is missing or contact failure
(5)
Disconnected pressure sensor cable
(6)
Failure of the pressure sensor input circuit on the
controller board
1500
Cause
Check method and remedy
(1)
Overcharged refrigerant
Refer to the page on refrigerant amount
evaluation.(page 117)
(2)
Thermistor input circuit failure on the control board
Check the temperature and pressure readings on the sen-
sor that are displayed on the LED monitor.
(3)
Faulty mounting of thermistor (TH4)
Check the temperature and pressure readings on the
thermistor that are displayed on the LED monitor.
(4)
Outdoor unit LEV2a, b actuation failure -> Heating
Refer to the section on troubleshooting the LEV.
