Cleaning the Front Panel

• Turn off the air conditioner.
• Clean the front panel with a soft, damp cloth.
• Air dry completely.

Repairing Paint Damage

Check for paint damage once or twice a year, especially in coastal areas or where rust is a problem. Touch up with a good grade enamel paint if needed.

Annual Maintenance

Annual maintenance ensures steady performance. Call your local authorized dealer to schedule a checkup. The expense of an annual inspection is your responsibility.

Troubleshooting

Try these suggestions before calling for service.

Air conditioner will not operate

• WARNING: [Electrical Hazard Symbol] 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.
• Power supply cord is unplugged. Plug into grounded outlet.
• Power supply cord has tripped (Reset button popped out). Press and release RESET to resume operation.
• Household fuse blown or circuit breaker tripped. Replace fuse or reset breaker. Call electrician if problem persists.
• Power button not pressed. Press the Power button.
• Local power has failed. Wait for power restoration.

Air conditioner blows fuses or trips circuit breakers

• Too many appliances on the same circuit. Unplug or relocate appliances.
• Time-delay fuse or circuit breaker of wrong capacity used. Replace with correct capacity.
• Extension cord is being used. Do not use extension cords.

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

• Electrical current disturbances can trip the cord. Press and release RESET to resume operation.
• Electrical overloading, overheating, cord pinching, or aging can trip the cord. After correcting, press and release RESET to resume operation.
• NOTE: A damaged power supply cord must be replaced with a new one from the manufacturer; do not repair.

Air conditioner seems to run too much

• If replacing an older model, newer units may run longer due to more efficient components, but consume less energy. Newer units may not emit as strong a "blast" of cold air but this indicates no loss of capacity or efficiency. Refer to EER and Btu/h ratings.
• Room is heavily occupied or heat-producing appliances are in use. Use exhaust fans for cooking/bathing. Avoid heat-producing appliances during hottest parts of day. A higher capacity unit may be needed for the room size.

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

• Unit may not be properly sized for the room. Check cooling capabilities. Units are not designed to cool multiple rooms.
• Filter is dirty or obstructed. Clean the filter.
• Inside evaporator and outside condenser coils are dirty or obstructed. See Annual Maintenance.
• Excessive heat or moisture in the room (e.g., cooking, showers). Use a fan to exhaust heat/moisture. Avoid heat-producing appliances during hottest parts of day.
• Louvers are blocked. Install unit where louvers are free from curtains, blinds, furniture, etc.

Additional Troubleshooting Points

• Extremely hot room: Allow extra time for cooling.
• Windows or doors open: Close all windows and doors.
• Temperature control setting too high: Adjust to a cooler setting. Set fan speed to highest.

Water drips from cabinet into your house

• Air conditioner is not properly leveled. It should slope slightly downward toward the outside for proper drainage. Level the unit.
• NOTE: Do not drill a hole in the bottom of the metal base and condensate pan.
