AIR FILTER CLEANING

Changing your air filter on a regular basis prevents many problems. Dirty air filters will affect

the performance and the longevity of your unit. It is recommended that air filters be cleaned

every three (3) months.

To access and clean the filter:

CARE AND CLEANING

Take notice of the following items before cleaning your Livo indoor wall unit.

• To avoid electric shock or injury, do not attempt to clean the unit unless it has been turned

off and the indoor and outdoor units have been disconnected from the main power supply.

• Do not wash the unit with water; this may cause an electric shock.

• During cleaning, be sure to use a stable and safe standing platform.

FRONT PANEL CLEANING

Wash the front panel using warm water and mild detergent with a soft cloth or soft brush.

NOTE: Do not use bleach,abrasives or water above 110°F (45°C) as it may cause

discoloration or damage to the surface of the unit.

1. Open Front Panel

Firmly grasp both sides of the front panel and pull upward

to about 60 degree angle. (NOTE: do not force panel open).

2. Remove Filter

Remove the filter as indicated in the figure at right.

3. Clean Filter

Use vacuum to clean the filter.

When the filter is very dirty, use warm water (below 110

°F

)

to clean it, and then dry filter before replacing.

4. Reinstall Filter

Reinstall the filter and then close the panel cover tightly.

WARNING

TROUBLESHOOTING

PROBLEM

System does not restart.

Indoor unit emits unpleasant odor

when started

You hear a“water flowing”sound.

A thin fog or vapor coming out

of the indoor unit when system is

running.

You hear a slight cracking sound

when the system stops or starts.

The system will not run.

The unit is not heating or cooling

adequately.

Water leakage from the

outdoor unit.

CAUSE/SOLUTION

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.

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

the coil surfaces or the 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.

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.

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.

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 will discontinue as temperature equalizes after 2 or 3 minutes.

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, contact a qualified service professional for assistance.

Cause: There are a number of reasons for inadequate cooling or heating.

Solution: Check the following:

• Remove obstructions blocking airflow into the room.

• Clean dirty or blocked air filter that is restricting airflow into the system.

• Seal around door or windows to prevent air infiltration into the room.

• Relocate or remove heat sources from the room.

Cause: It is normal for the outdoor unit to generate condensate water in the

reverse cycle heating and defrost mode.

Solution: This is normal. No action is required.

CAUTION

TROUBLESHOOTING

PROBLEM

Water leaking from the indoor

unit into the room.

Wireless remote controller

does not work.

The unit will not deliver air.

Moisture or condensation

on the discharge air louvers

or outlet vents.

CAUSE/SOLUTION

Cause: While it is normal for the system to generate condensate water in cooling

mode, it is designed to drain this water via a condensate drain system to a safe location.

Solution: 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 pipe is restricted or plugged. All restrictions must

be removed to allow continuous drainage by gravity.

• If problem persists, contact a qualified service professional for assistance.

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. (7.5 m) with no obstructions

of the indoor unit. If remote controller needs to be replaced, contact a

qualified service professional for assistance. In the meantime, use the

Aux Button to operate the system.

Cause: There are a number of system functions that will prevent air flow.

Solution: Check for the following:

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

room temperature is very low. This is to prevent blowing cold air.

• In heat mode, if the outdoor temperature is low and humidity is high,

the system may need to defrost for up to 10 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.

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.

top 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.

• Water is leaking in the room.

• You notice a burning smell or see smoke.

• Circuit breaker trips frequently, or unit stops abnormally often.

ENERGY SAVING TIPS

1. Reduce room setpoint at night: During the nighttime hours you don't require the

same level of conscious cooling or heating. 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, it is recommended 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. In winter, the sun is your friend. Open curtains and shades to

allow solar heat into your room.

3. Close doors: If you don’t need to heat and cool your whole home, confine the heat-

ing and cooling to one room by closing doors.

4. Service the unit: Some basic maintenance might be all you need. The outdoor unit

will greatly benefit from a good hosing off, 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 heating

and cooling the back of a chair instead of the actual living space. 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 heat. 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 unit to Auto mode and

make sure windows and curtains are closed. Although room temperature may be less

than optimal for a few minutes when you return, the unit will soon have the room

back to your desired temperature.

9. Don't forget the fan: The fan is much like a car. The faster it runs, the more energy it

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.
