to the below v)
i) If an excessively low voltage state (180V or below) is continued for 4 seconds or longer,
mains lighting up even after the voltage has been recovered.
ii) If the voltage drops down to a low voltage level of 160V or below,
short beep sounds (Pi, Pi, Pi, ...), until power switch is turned off.
If the voltage drops down further and motor stops with error,
beep sounds (Pi, Pi, Pi, ...), until power switch is turned off.
iii) If an excessively high voltage state (255V or over) is continued for 2 seconds or longer,
up without beep sounds.
iv) If the voltage increases to a high voltage level of 265V or over for 2 seconds or longer, motor stops
automatically and
turned off.
v) In other cases of abnormal motor stop automatically,
beep sounds (Pi, Pi, Pi, ...), until power switch is turned off.

Symptom
Cause
Voltage is too low or high
• Motor temperature
went abnormally high
• Temperature in the
control circuit has built
up to an abnormally
high level
(LED remains lighting
up.)
• Motor does not run
• Failure in the control
circuit
(LED remains blinking.)

Actions taken
Examine the state of the
power supply (See
page 23)
• Do not use the com-
pressor in extremely
high temperatures.
• Do not clog the airflow
orifice.
• Examine the state of
the power supply
(See page 23)
• Do not use the com-
pressor in a place
where it can be
splashed with water or
in a highly humid place.
It is due to a failure on the
inverter or motor. Send
the machine to your deal-
er or authorized service
facility to have their
checkup or repair.
