The air conditioner unit must always be stored and transported upright, otherwise you may cause irreparable damage to the compressor. In case of doubt, we suggest that you wait for at least 24 hours before you start the air-conditioning unit.

A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

  • Do not plug this machine into an outlet with several other high electrical usage appliances.
  • Keep the machine away from heat sources and avoid direct sunlight.
  • If the machine is making a loud noise or producing an odor or smoke, switch off it, disconnect the plug, and immediately try to determine the cause.
  • Do not place heavy objects on the power cord to avoid it being crushed and causing an electric shock.
  • Do not put your fingers or hard objects into the outlet air guide bars.
  • Turn the machine off and unplug it if there is water inside it, then contact qualified service personnel for servicing.
  • Turn the machine off and unplug it before cleaning, moving, or servicing it.

  • Do not use aerosol sprays or other solvents near the machine. This may cause plastic deformation or possibly damage the electrical components of the machine.
  • Avoid restarting the air conditioning unit unless three minutes have passed since being turned off, or the compressor may get damaged.


Failure to follow these instructions can result in electric shock, fire, or death.

  • This unit must be properly grounded.
  • Do not, under any circumstances, cut or remove the grounding plug.
  • If you do not have a properly grounded AC outlet, or if there is any doubt that the outlet is not properly grounded, a qualified electrician should check the outlet and circuit and, if necessary, install a properly grounded outlet.
  • This air conditioner must be plugged into a grounded 115V, 60Hz AC outlet, protected by a 15 amp time-delay fuse or circuit breaker.
  • This air conditioner must be installed in accordance with national wiring codes.
  • Do not alter or modify the plug or cord of this air conditioner. If the power cord becomes worn or damaged, the cord should only be replaced by a qualified service technician using genuine replacement parts.
  • Do not use an extension cord.


Integrated circuit breaker.
For additional safety, the power cord on this air conditioner features an integrated circuit breaker. You can test and reset the circuit breaker using the buttons provided on the plug case.
Consult a qualified electrician or service person if the grounding instructions are not completely understood, or if doubt exists as to whether the air conditioner is properly grounded.
Electric Safety
The circuit breaker should be tested periodically by pressing the TEST button, then pressing the RESET button. If the TEST button does not cause the circuit breaker to trip, or if the RESET button does not stay engaged, unplug the air conditioner immediately and contact an Insignia technician.

Preferred grounding method.
Grounding Method  

Temporary grounding
Due to potential safety hazards, we strongly discourage the use of an adapter plug. If an adapter plug must be used for a temporary connection, use only a UL-listed adapter. The minimum capacity for 10,000 BTU is 120V, 60Hz, 13A, and 1560W, and for 12,000 BTU is 120V, 60Hz, 15A, and 1800W.
Make sure that the large slot of the adapter is aligned with the large slot in the outlet.
Temporary Grounding

To prevent damage to the adapter’s ground terminal, hold the adapter in place while plugging or unplugging the air conditioner.
Attaching the adapter ground terminal to the wall receptacle cover screw does not ground the appliance unless the cover screw is metal and not insulated and the wall receptacle is grounded through the house wiring.
Frequent connection and disconnection can damage the ground terminal on the adapter. Never use a broken or damaged adapter.
