Having trouble?
Noise is louder than specifications.
Nothing appears in the wireless remote controller display, the display
is faint, or signals are not received by the indoor unit unless the remote
controller is close.
After battery installation/replacement of remote controller, part of function
cannot be used.
The operation lamp near the receiver for the wireless remote controller on
the indoor unit is flashing.
The wireless remote controller does not operate (the indoor unit beeps
4 times).
The indoor unit which is not operating becomes warm and a sound, similar
to water flowing, is heard from the unit.
