Error code
E60
Remote control:
1. Applicable model
Models SRC40-60
2. Error detection method
Compressor rotor position
3. Condition of error displayed
If it fails again to detect the
rotor position after shifting to
the compressor rotor position
detection operation, the
compressor stops.
4. Presumable cause
• Defective outdoor fan motor
• Defective outdoor unit PCB
• Anomalous power source
voltage
• Improper refrigerant amount
and refrigerant circuit
• Defective compressor (motor,
bearing)
Note: Insulation resistance
• The unit is left for long period without power source or soon after installation, migrated liquid refrigerant may dissolve in the refrigerant oil in the compressor.
In such case insulation resistance decreases upto several MW or lower. If the electric leakage breaker is activated due to low insulation resistance, check followings.
➀ Check 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.)
➁ C heck whether the electric leakage breake conforms to high-hermonic specifications.
(As units has inverter, in order to prevent from improper operation, be sure to use high-hermonic one.)

Diagnosis
Is the
power source voltage
OK?
YES
Reset the power source and restart operation.
Does the compressor start?
YES
Is the
output from inverter
checker OK?
YES
Is the noise
or vibration of compressor
normal?
YES
Does it
start up normally without
recurrence of
E60.
