Recommended Grounding Method
This air conditioner must be grounded. This air conditioner is equipped with a power supply cord with a three-prong grounding plug. The cord must be plugged into a mating, grounded three-prong outlet, grounded in accordance with all local codes and ordinances. If a mating outlet is not available, it is the customer’s responsibility to have a properly grounded three-prong outlet installed by a qualified electrical installer.

It is the customer’s responsibility:
To contact a qualified electrical installer. To assure that the electrical installation is adequate and conforms to the Nation Electrical Code,ANSI/NFPA 70-last edition,and all local codes and ordinances.
Copies of the standards listed may be obtained from: Nation Fire Protection Association 1 Batterymarch Park Quincy,Ma 02169-7471 www.nfpa.org

Power Supply Cord

NOTE: Your air conditioner’s device may differ from the one shown. This room air conditioner is equipped with a power supply cord required by UL. This power supply cord contains state-of-the-art electronics that sense leakage current. If the cord is crushed, the electronics detect leakage current and power will be disconnected in a fraction of a second.

To test your power supply cord:

1. Plug power supply cord into a grounded 3 prong outlet.
2. Press RESET (on some devices, a green light will turn on).
3. Press TEST (listen for click; Reset button will trip, and on some devices, a green light will turn off).
4. Press and release RESET (listen for click; Reset button will latch, and on some devices, a green light will turn on). The power supply cord is ready for operation.

NOTE:

• The Reset button must be pushed in for proper operation.
• The power supply cord must be replaced if it fails to trip when the test button is pressed or fails to reset.
• Do not use the power supply cord as an off/on switch. The power supply cord is designed as a protective device.
• A damaged power supply cord must be replaced with a new power supply cord obtained from the product manufacturer and must not be repaired.
• The power supply cord contains no user serviceable parts. Opening the tamper-resistant case voids all warranty and performance claims.

TROUBLESHOOTING

Before calling for service, try the suggestions below to see whether you can solve your problem without outside help.

Air conditioner does not operate

Electrical Shock Hazard

Plug into a grounded 3 prong outlet.
Do not remove ground prong.
Do not use an adapter.
Do not use an extension cord.
Failure to follow these instructions can result in death, fire, or electrical shock.

• The power supply cord is unplugged. Plug into grounded 3 prong outlet. See “Electrical Requirements”.
• The power supply cord has tripped (Reset button has popped out). Press and release RESET (listen for click; Reset button will latch and on some devices, a green light will turn on) to resume operation.
• A household fuse has blown, or circuit breaker has tripped. Replace the fuse or reset the circuit breaker. If the problem continues, call an electrician. See “Electrical Requirements”.
• The Power button has not been pressed. Press the Power button.
• The local power has failed. Wait for power to be restored.

Air conditioner blows fuses or trips circuit breakers

• Too many appliances are being used on the same circuit. Unplug or relocate appliances that share the same circuit.
• Time-delay fuse or circuit breaker of the wrong capacity is being used. Replace with a time-delay fuse or circuit breaker of the correct capacity. See “Electrical Requirements”.
• An extension cord is being used. Do not use an extension cord with this or any other appliance.
• You are trying to restart the air conditioner too soon after turning off the air conditioner. Wait at least 3 minutes after turning off the air conditioner before trying to restart the air conditioner.

Air conditioner power supply cord trips (Reset button pops out)

• Disturbances in your electrical current can trip (Reset button will pop out) the power supply cord. Press and release RESET (listen for click; Reset button will latch and on some devices, a green light will turn on) to resume operation.
• Electrical overloading, overheating, cord pinching or aging can trip (Reset button will pop out) the power supply cord. After correcting the problem, press and release RESET (listen for click; Reset button will latch, and on some devices, a green light will turn on) to resume operation.

NOTE: A damaged power supply cord must be replaced with a new power supply cord obtained from the product manufacturer and must not be repaired.

Air conditioner seems to run too much

• The current air conditioner replaced an older model. The use of more efficient components may cause the air conditioner to run longer than an older model, but the total energy consumption will be less. Newer air conditioners do not emit the “blast” of cold air you may be accustomed to from older air conditioners, but this is not an indication of lesser cooling capacity or efficiency. Refer to the efficiency rating (EER) and capacity rating (in Btu/h) marked on the air conditioner.
• The air conditioner is in a heavily occupied room, or heatproducing appliances are in use in the room. Use exhaust vent fans while cooking or bathing and try not to use heat-producing appliances during the hottest part of the day. A higher capacity air conditioner may be required, depending on the size of the room being cooled.

Air conditioner cycles on and off too much or does not cool

• The air conditioner is not properly sized for your room. Check the cooling capabilities of your room air conditioner. Room air conditioners are not designed to cool multiple rooms.
• The filter is dirty or obstructed by debris. Clean the filter.
• The inside evaporator and outside condenser coils are dirty or obstructed by debris. See Annual Maintenance.
• There is excessive heat or moisture (open container cooking, showers, etc.) in the room. Use a fan to exhaust heat or moisture from the room. Try not to use heat-producing appliances during the hottest part of the day.
• The louvers are blocked. Install the air conditioner in a location where the louvers are free from curtains, blinds, furniture, etc.
• The temperature of the room you are trying to cool is extremely hot. Allow extra time for the air conditioner to cool off a very hot room.
• Windows or doors to the outside are open. Close all windows and doors.
• The Temp control is not at a cool enough setting. Adjust the Temp control to a cooler setting by pressing the minus button to reduce the temperature. Set the Fan Speed control to the highest setting.

Water drips from the rear of the unit

• You see water dripping from the rear of the unit. Water may be collected in the base pan in highly humid conditions or on rainy days. This water overflows and drips from the rear of the unit.

Water drips from cabinet into your house

• The air conditioner is not properly leveled. The air conditioner should slope slightly downward toward the outside. Level the air conditioner to provide a downward slope toward the outside to ensure proper drainage. See the Installation Instructions.

NOTE: Do not drill a hole in the bottom of the metal base and condensate pan.
