❇ During "Discharge mode of DC link voltage", voltage of INV1 and INV2 will be displayed alternately .
❇
❇ Even when the outdoor unit power is off, it is dangerous when you come in contact with inverter PCB and fan PCB
❇
since they are charged with high DC voltage .
❇ When pressing K2 key 9 to 12 times without inverter checker, error code can be displayed on segment even though
❇
the outdoor unit is normal .
❇ When replacing/repairing the PCB, cut-off the power and wait until the DC voltage is discharged before replacing/
❇
repairing them . (Wait for more than 15 minutes to allow it to discharge naturally .)
❇ When there were error, 'Discharge mode of DC link voltage' may not have been effective . Especially if error E464
❇
and E364 have been occurred, power element might be damaged by fire and therefore, do not use the 'Discharge
mode of DC link voltage' .
❇ If the 1st-generation MCU is installed, the Auto pipe pairing operation can not be used .
❇
If the 2nd-generation MCU is installed, the Checking the pipe connection can not be used .
- 1st-generation MCU : MCU-S*NEE*N, MCU-S2NEK1N
- 2nd-generation MCU : MCU-S*NEK2N,MCU-S4NEK3N,MCU-S1NEK1N
❇ If there is an A type PBA among the outdoor units installed as a module, the Auto pipe pairing operation can not
❇
be used .
