Test in resistance.
TOOL: Multimeter.
Test the resistance of the main winding. The outdoor fan motor is fault if the
resistance of main winding 0(short circuit)or∞（open circuit）.
Notes:
1) Please don't hold motor by lead wires.
2) Please don't plug IN/OUT the motor connector while power ON.
3) Please don't drop .Hurl or dump motor against hard material.Malfunction may not
be observed at early stage after such shock.But it may be found later,This type of
mishandling void our warranty.
3. COMPRESSOR
COMPRESSOR EXAMINE AND REPAIR.
Test in resistance.
TOOL: Multimeter.
Test the resistance of the winding. The compressor is fault if the resistance of
winding 0(short circuit)or∞（open circuit）
Familiar trouble: 1) Compressor motor lock. 2）Discharge pressure value approaches
static pressure value .3) Compressor motor winding abnormality.
Notes：1）Don't put a compressor on its side or turn over.
2) Please assembly the compressor in your air conditioner rapidly after removing
the plugs. Don't place the comp. In air for a long time.
3) Avoiding compressor running in reverse caused by connecting electrical wire
incorrectly.
