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:

Solution:

Indoor unit emits unpleasant

Cause:

odor when started.

Solution:

You hear a "water flowing"

Cause:

sound.

Solution:

A thin fog or vapor coming

Cause:

out of the indoor unit when

system is running.

Solution:

You hear a slight cracking

Cause:

sound when the system

stops or starts.

Solution:

The system will not run.

Cause:

Solution:

Heating or cooling

Cause:

not running efficiently.

Solution:

The system has a built-in three-minute delay to prevent short and/or rapid cycling

of the compressor.

Wait three minutes for the protection delay to expire.

Typically unpleasant odors are the result of mold or mildew forming on the coil

surfaces or air filter.

Wash indoor air filter in warm water with mild cleaner. If odors persist, contact

a qualified service professional to clean the coil surfaces.

It is normal for the system to make "water flowing" or "gurgling" sounds from

refrigerant pressures equalizing when the compressor starts and stops.

The noises should discontinue as the refrigerant system equalizes after two or

three minutes.

It is normal for the system to emit a slight fog or water vapor when cooling

extremely humid warm air.

The fog or water vapor will disappear as the system cools and

dehumidifies the room space.

It is normal for the system to make "slight cracking" sounds from parts expanding

and contracting during system starts and stops.

The noises should discontinue as temperature equalizes after two or three minutes.

There are a number of situations that will prevent the system from running.

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.

With routine maintenance, your system is designed for years of peak efficiency.

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.

The unit will not deliver air.

Cause:

Solution:

Moisture or condensation

air louvers or outlet vents.

Solution:

CAUTION

WARNING

C UTION

Stop operation and call for service in the following circumstances:

• You hear a harsh or unusual sound during operation

• Unusually foul odor is emitted during operation

• Circuit breaker trips frequently, or unit stops

abnormally often

There are a number of possible reasons.

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.

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.

• 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.

It is normal for outdoor unit to generate condensate water in reverse cycle

heating mode and defrost.

This is normal. No action is required.

There are a number of system functions that will prevent the indoor fan from running.

Check for the following:

• In heating mode, the indoor fan may not start for three minutes if the room

temperature is very low to prevent blowing cold air.

• I n heat mode, if the outdoor temperature is low and humidity is high, the system

may need to defrost for up to 12 minutes before beginning a heating cycle.

• 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.

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.

The condensation or moisture will disappear as the system cools and

dehumidifies the room space.

• Water is leaking in the room

• Liquid is spilled into unit

• You notice a burning smell or

see smoke
