*Fixed Hz operation may not be possible under the following tempera- ture ranges.

A)In cool mode, outdoor intake air temperature is 104˚F or higher or indoor intake air temperature is 73˚F or lower.

B)In heat mode, outdoor intake air temperature is 68 ˚F or higher or indoor intake air temperature is 77 ˚F or lower.

*If the air conditioner is operated at a temperature range other than the ones above but operation is not stabilized after 30 minutes or more have elapsed, carry out inspection.

*In heat mode, the operation state may vary due to frost forming on the

outdoor heat exchanger.
