WARNING

Do not attempt any repairs on the unit yourself. Incorrect repair can cause shock or fire. Always call a qualified service professional. Using these troubleshooting suggestions can save time when you contact the qualified service professional.

PROBLEM
CAUSE/SOLUTION

System does not restart.	Cause: The system has a built-in three-minute delay to prevent short and/or rapid cycling of the compressor.Solution: Wait three minutes for the protection delay to expire.
Indoor unit emits unpleasant odor when started.	Cause: Typically unpleasant odors are the result of mold or mildew forming on the coil surfaces or air filter.Solution: Wash indoor air filter in warm water with mild cleaner. If odors persist, contact a qualified service professional to clean the coil surfaces.
You hear a "water flowing" sound.	Cause: It is normal for the system to make "water flowing" or "gurgling" sounds from refrigerant pressures equalizing when the compressor starts and stops.Solution: The noises should discontinue as the refrigerant system equalizes after two or three minutes.
A thin fog or vapor coming out of the indoor unit when system is running.	Cause: It is normal for the system to emit a slight fog or water vapor when cooling extremely humid warm air.Solution: The fog or water vapor will disappear as the system cools and dehumidifies the room space.
You hear a slight cracking sound when the system stops or starts.	Cause: It is normal for the system to make "slight cracking" sounds from parts expanding and contracting during system starts and stops.Solution: The noises should discontinue as temperature equalizes after two or three minutes.
The system will not run.	Cause: There are a number of situations that will prevent the system from running.Solution: Check for the following:Circuit breaker is "tripped" or "turned off."Power button of remote is not turned on.Batteries in the remote controller are low.Remote controller is in sleep mode or timer mode.Otherwise, you should contact a qualified service professional for assistance.
Cooling not running efficiently.	Cause: With routine maintenance, your system is designed for years of peak efficiency.Solution: Check the following:Remove obstructions blocking airflow into the room.Clean dirty or blocked indoor air filter that is restricting airflow into the system.Seal outdoor air leaks in the room space from door or windows.Relocate (if possible) other heating sources in the room space.

TROUBLESHOOTINGTROUBLESHOOTING

PROBLEM	CAUSE/SOLUTION
Wireless remote controller lost or does not work.	Cause: There are a number of possible reasons.Solution: Check the following:The batteries might be low. Change the batteries.The remote controller must be within 25 ft. (7.6 m) with no obstructions of the indoor unit. If remote controller is lost or damaged and needs to be replaced, contact your qualified service professional for assistance. In the meantime, use the manual override mode to operate the system.
Water leaking from indoor unit into the room.	Cause: While it is normal for the system to generate condensate water in cooling mode, it is designed to drain this water to the outdoors via a condensate drain tube. If water is leaking into the room, it may indicate one of the following.Solution: The indoor unit is not level right to left. Level indoor unit.The condensate drain tube is restricted or plugged. All restrictions must be removed to allow continuous gravity force drainage.If problem persists, contact a qualified service professional for assistance.
The unit will not deliver air.	Cause: There are a number of system functions that will prevent the indoor fan from running.Solution: In dry mode, the indoor fan may stop for up to three minutes during the compressor off delay. Otherwise, you should contact a qualified service professional for assistance.
Moisture or condensation on the discharge air louvers or outlet vents.	Cause: It is normal for the system to develop condensation or moisture on the discharge air louvers when cooling warm humid air for a long period of time.Solution: The condensation or moisture will disappear as the system cools and dehumidifies the room space.

CAUTION

Stop operation and call for service in the following circumstances:

• You hear a harsh or unusual sound during operation • Water is leaking in the room
• Unusually foul odor is emitted during operation
• Liquid is spilled into unit
• Circuit breaker trips frequently, or unit stops abnormally often
• You notice a burning smell or see smoke

COOLING OPERATION

How it works:

In cooling mode, youmeo indoor unit will absorb heat from the room, then the neo outdoor unit will discharge the heat to the outdoors. Theo cooling capacity decreases as the outdoor temperature increases. This causes theo to work harder and longer to hold the selected room temperature. Youneo unit will operate in cooling down to 41°F (5°C)

Indoor Coil Freeze Protection:

Frost may form on the indoor coil during cooling operations when the outdoor temperature below 50^ F ( 10^ C). Prolong operation may cause ice to form on the indoor coil and block airflow. If the indoor unit microcomputer detects ice on the indoor coil it will stop the compressor to defrost the coil and protect the unit.

1. Relaxing room temperature at night is OK: During the nighttime hours you don't require the same level of conscious cooling. Try using Sleep Mode to gradually relax room temperature and allow the unit to run less and save energy.
2. Curtains and shades: In the summer, you need to block the effects of the sun. Close window curtains and shades on the south and west side of your home to help block solar heat.
3. Close doors: If you don't need to cool your whole home, confine the cooling to one room by closing doors. Limit the space you're cooling to specified capability of the unit.
4. Service the unit: Some basic maintenance might be all you need. The outdoor unit will greatly benefit from a good hosing out, especially in treed areas where seeds and other debris can stick to coil fins and make the unit work up to 15% harder!
5. Rearrange the room: Furniture that obstructs airflow means you could be cooling the back of a chair or the front of a sofa instead of the actual living space. Use the Swing Louvers to help direct the air in the right direction for the room; remove or rearrange obstacles blocking airflow.
6. Try 75 degrees: 75^ F is a good point for an air conditioner to run at its optimal performance level. Even a 5-degree change in temperature can make your unit use up to 40% more energy!
7. Lighting: Turning lights off can help reduce your cooling. Each light bulb is a tiny heater. Your air conditioner must waste energy overcoming the heat from your lights to reach and hold your desired room temperature.
8. Is anyone home? If possible, while you're away turn your setpoint temperature up and make sure windows and drapes are closed. Although the room temperature will be uncomfortable for a few minutes when you come home, the unit will have the room back to your desired temperature in no time.
9. Don't forget the fan: The fan is much like a car. The faster it runs, the more energy is uses. Sometimes we need the car to go fast, but slow is good enough most of the time. Try saving money by using the comfortable quiet low fan speed as much as possible.
