Diagnosis
Countermeasure
Is the
power source voltage
OK?
Reset the power source and restart operation.
Does the compressor start?
Does E59 occur?
NO
Does it
start up normally without
recurrence of
E60.
NO
Does the
compressor run without
occurrence of
E42?
Is the noise
or vibration of compressor
normal?
Is the
output from inverter
checker OK?

Replace.
Replace compressor.
Check compressor for
insulation, resistance.
Replace compressor if
necessary.

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 main 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 M
Ω
or lower. If the electric leakage breaker is activated due to low insulation resistance, check followings.
①
Check 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.)
