Is the
difference between
high and low pressure
before startup not more
than 0.2MPa?
Turn the main power supply
off, and then disconnect the
connection between the
compressor and inverter.
Is the
inverter output
voltage generated
approximately at the same
increasing speed on each
phase after turning
on again? (

(U-V, V-W,
W-U)
Continuity check in the
power transistor (IGBT)
Is the continuity
normal?
Is the stop valve open?
Check the
installation conditions.
Caution
Be sure to turn off power switch before connect or disconnect connector,

* When operating compressor
with compressor output line
disconnected, the compressor
stops due to malfunction after
elapsed time of 5 seconds.
Therefore, check the voltage
increase for 5 seconds.
Open the stop valve.
Insufficient pressure equalization
Check refrigerant system.

Compressor inspection
Inspect according to the diagnosis
procedure for abnormal noises,
vibration, operating status, etc. of
