The air conditioner should always be plugged into its own individual electrical outlet which has a voltage rating that matches the rating plate.
The power cord of this appliance is equipped with a 3-prong (grounding) plug which mates with a standard 3-prong (grounding) wall outlet to minimize the possibility of electric shock hazard from this appliance.
This provides the best performance and also prevents overloading house wiring circuits which could cause a fire hazard from overheated wires.
Have the wall outlet and circuit checked by a qualified electrician to make sure the outlet is properly grounded.
Where a 2-prong wall outlet is encountered, it is your personal responsibility and obligation to have it replaced with a properly grounded
3-prong wall outlet.
See the Installation Instructions, Electrical
Requirements section for specific electrical connection requirements.
USE OF EXTENSION CORDS 115-Volt models only
Because of potential safety hazards under certain conditions, we strongly recommend against the use of an extension cord.
DO NOT use an extension cord with any of the 230/208 volt models.
However, if you must use an extension cord, it is absolutely necessary that it be a UL-listed,
14 gauge, 3-wire grounding type appliance extension cord having a grounding type plug and outlet and that the electrical rating of the cord be 15 amperes (minimum) and 125 volts.
USE OF ADAPTER PLUGS 115-Volt models only
Because of potential safety hazards under certain conditions, we strongly recommend against the use of an adapter plug.
The larger slot in the adapter must be aligned with the larger slot in the wall outlet to provide proper polarity in the connection of the power
When disconnecting the power cord from the adapter, always hold the adapter in place with one hand while pulling the power cord plug with the other hand. If this is not done, the adapter ground terminal is very likely to break with repeated use.
If the adapter ground terminal breaks, DO NOT
USE the air conditioner until a proper ground
has been established.
Attaching the adapter ground terminal to a wall outlet cover screw does not ground the appliance unless the cover screw is metal, and not insulated, and the wall outlet is grounded through the house wiring. You should have the cir
