WARNING
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 a 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 remain in) to resume operation.
■A household fuse has blown, or a circuit breaker has tripped. Replace the fuse or reset the circuit breaker. If the problem continues, call an electrician. See “Electrical Requirements.”
■The Fan Speed control is turned to the off position. Turn the Fan Speed control to an active setting.
■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.
■
■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 the Fan control off. Wait at least 3 minutes after turning the Fan control off before trying to restart the air conditioner.
■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 remain in) 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 remain in) 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 units, 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 heat- producing 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/heat room in cooling/heating mode
■The Fan Speed control is set to Power Saver (on some models). Use Power Saver only when you are asleep or away from home, since the fan does not circulate the room air continuously. Use Low Cool, High Cool, Turbo Cool, Turbo Heat or Low Heat for your best comfort.
■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.”
