1. When power is on, it checks the power status used for 3-phase power compressor.
When the order of 3-phase L1(R) – L2(S) – L3(T) is changed (reversed) or there is a phase that does not receive power (phase fai l ) ,
it will display [E425] and the air conditioner will stop operating.
1) Check the voltage on L1(R) – L2(S) phase/ L1(R) – L3(T) phase/
L2(S) – L3(T) phase.
2) When there is any terminal that does not have normal voltage,
check the external power of the air conditioner and take
appropriate measures.
3) If 3-phase power is normal check the phase of the power line using
3-phase tester. If it shows reverse phase, please change the current
power line connection.
4) After completing above, press reset key (K3) then check the power again.
