1. SAFETY PRECAUTIONS
Electrical Safety
  CAUTION : The power cord of this air conditioner contains a current sensing device designed to 
reduce the risk of re. Please refer to the Operation of Current Device section below for more details. 
If the power cord is damaged, it cannot be repaired. It must be replaced with a power cord from the 
product manufacturer.
▪  The  power  cord  is  equipped  with a  3-prong grounding  plug that  can only  be used  with a  standard 
3-prong wall outlet to minimize the risk of electric shock. If you have a 2-prong plug, it is your responsi-
bility to replace it with a properly grounded 3-prong wall outlet.
▪  Do not use a power cord that has any damage or cracks along the length or at the connector. A dam-
aged power cord must be replaced with a new cord obtained from the manufacturer. Please contact 
Customer Service for replacement options.
▪  Do not alter the length of the power cord or share an outlet with another device. Doing so may result in 
electric shock or re.
▪  Always use a dedicated power circuit. The voltage of the  plug must match the voltage rating on the 
nameplate.
▪  Do not use an outlet if it is loose or damaged. Doing so may cause electric shock.
▪  Never use an extension cord, surge protector, or power strip adapter with this unit.
Operation of Current Device
The  power  supply  cord  contains  a  current  device  that  senses 
damage to the power cord. To  test  your  power  supply cord, do 
the following :
1. Plug the power supply cord.
2. The power supply cord has 2 buttons on the plug head. Press 
the TEST button. You should hear a clicking sound as the 
RESET button pops out.
3.  Press the RESET button. Again, you should hear a click as the 
button engages.
4. The power supply cord is now supplying electricity to the unit 
(on some devices this is indicated by a light on the plug head).
Notes :
▪  Do not use the power cord to turn the unit on or off.
▪  Always make sure the RESET button is pressed down for proper operation.
▪  The power cord must be replaced if it fails to reset when the TEST button is pressed, or if it cannot be 
reset. Please contact Customer Service.
▪  If the power cord is damaged, it cannot be repaired. It MUST be replaced with a new power cord. Please 
contact customer service.
NOTICE :  If you turn off the air conditioner, wait at least three minutes before turning it on again. This 
prevents the unit from blowing a fuse or tripping a circuit breaker.
