WARNING: Attaching the adapter ground terminal to the wall

10 Room Air Conditioner

We strongly discourage the use of an adapter due to potential :safety h_ards..
For temporary connections, use only a UL-fisted adapter, available from most

local hardware stores. Ensure that the, large slot in the adapter is aligned with
the large slot in the receptacle for a proper polarity connection.

To disconnect the power cord from the adapter, use one hand on each to avoid
damaging the ground terminal. Avoid frequently unplugging the p,ower cord as

this can lead to eventual ground terminal damage.
