1. In quiet operation or stopping the running, its heard slight flowing noise of
refrigerant in the refrigerating cycle occasionally, but this noise is not abnormal
for the operation.
2. When it thunders near by, it is recommend to stop the operation and to
disconnect the power cord plug from the power outlet for safety.
3. The room air conditioner dose not start automaticaly after recovery of the
electric power failure for preventing fuse blowing. Re-press START / STOP
button after 3 minutes from when unit stopped.
4. If the room air conditioner is stopped by adjusting thermostat, or missoperation,
and re-start in a moment, there is occasion that the cooling and heating
operation does not start for 3 minutes, it is not abnormal and this is the result
of the operation of IC delay circuit. This IC delay circuit ensures that there is
no danger of blowing fuse or damaging parts even if operation is restarted
accidentally.
5. This room air conditioner should not be used at the cooling operation when the
outside temperature is below –10˚C (14˚F).
6. This room air conditioner (the reverse cycle) should not be used when the
outside temperature is below –15˚C (5˚F).
If the reverse cycle is used under this condition, the outside heat exchanger is
frosted and efficiency falls.
7. When the outside heat exchanger is frosted, the front is melted by operating
the hot gas system, it is not trouble that at this time fan stops and the vapour
may rise from the outside heat exchanger.
