.6 Over-current of the compressor

Outdoor Display: LED1 flash 3 or 24 or 25 times

The current of the compressor is too high

when the IPM Module is damaged

or the compressor is damaged.

power supply voltage is too low or too high

■

Faulty IPM Module

■

Faulty compressor

■

Faulty power supply

* Caution Be sure to turn off power switch before connect or disconnect connector, or

parts damage may be occurred.

Electrify the machine again and turn it on

with the remote controller, If malfunctions

are reported before or upon the compressor

being started up,

IPM Module is damaged and

needs replacing.

Repair the power supply

The system may have been over or under

charged with gas, which can be judged through

the pressure of the measuring system.

YES

Yes

The compressor is started normally, but

malfunctions are reported after it has

run for some time. Check the power

supply is too low or too high
