Introduction to basic functions

Basic cooling functions

Air conditioner function:

To bring the ambient temperature to a comfortable level, the air conditioner absorbs heat from inside the room and discharges it outside.

Anti-freezing function:

If the unit is running in COOL mode and in low temperature, there will be frost formed on the heat exchanger, when indoor heat exchanger temperature decreased below 0°C, the indoor unit microcomputer will stop compressor running and protect the unit.

Basic heating functions

Heating function:

* Heat is generated from the outdoor unit is discharged inside to increase the temperature of the room. The heating effect will decrease in very cold outdoor conditions.

* If outside temperatures become very low, it may be necessary to use additional heating equipment.

Defrosting:

* When the unit is on for long periods of time and outside temperatures are low with high humidity, frost will form on the outdoor unit. The auto defrosting function will start, and the heat will stop for 8-10 minutes.

* During auto defrosting the fan motors will stop.

* During defrosting the indoor indicator light flashes and the outdoor unit will possibly give off some water vapor. This is not a malfunction.

* After defrosting is complete, heating will start automatically.

■

Introduction to basic functions

Anti-cool wind function:

To prevent cool wind from blowing in Heat mode, the indoor fan will not start if the indoor heat exchanger has not reached the correct temperature within 2 minutes. The anti-cool wind function operates in these conditions:

1. When Heating starts.

2. After Auto Defrost is complete.

3. When temperatures are low.

Gentle Breeze:

The indoor unit may blow a gentle breeze, and the guide louver rotate when:

1. When the unit is turned on in Heat mode and the compressor has not started.

Do not try to repair the air conditioner; there is danger of electric shock or fire. Please refer to the troubleshooting section before requesting service; you may be able to save time and money.

Condition

There is a delay in operation after the air conditioner has started.

Waiting

Troubleshooting

• As a precaution, operation cannot be resumed for approximately 3 minutes after the air conditioner has stopped.

An unusual smell is coming from the air conditioner.

Sound of water flowing heard during operation.

• This unit does not have any particular odour.

If you detect an odour, it will be the odour of accumulated substances.

• Solution method: Cleaning the air filter. If the problem persists, the air conditioner requires further cleaning. (Please contact an authorized maintenance center.)

• When the air conditioner is started or stopped, the compressor starts and sometimes creates gurgling sounds. The sounds are caused by the flowing of refrigerant.

Sometimes mist comes out of the air outlet vent in COOL mode.

• If indoor temperatures and relative humidity are high, this can happen when air in the room is cooled down too quickly. Indoor temperatures and humidity will decrease after operating for a while.

Creaking noise heard during start or stop.

• This is caused by deformation of the plastic due to changes in temperature.

■

Troubleshooting

Condition

The unit does not operate.

Breaker off

Cooling (Heating) effect is not sufficient.

Remote controller does not operate.

Water leakage in the room.

Water leakage is coming from the outdoor unit.

Noise is coming from the indoor unit.

Troubleshooting

• Make sure the power is on.

• Make sure the power cord is connected.

• Make sure the circuit protection device has not been tripped.

• Voltage maybe too high or too low.

(To be tested by professionals only)

• Make sure the TIMER is being used correctly.

• Check the temperature setting.

• Make sure inlet and outlet vents are not blocked?

• The air filter may be dirty.

• Make sure windows and doors are closed.

• The fan speed may be set too low.

• Other contributing sources of heat/cold.

• If the unit functions are too frequently switched, sometimes the controller will not operate. At this time, disconnect the plug, connect again and try to start operation.

• Make sure the remote controller is within range. Check for obstructions. Replace the batteries in the remote controller.

• The remote controller may be damaged.

• High relative humidity

• Condensed water

• The indoor unit drainage pipe connection is loose.

• When the unit operates in COOL mode, the pipe and connection are cooled down which creates condensed water.

• When the unit operates in Auto Defrost mode ice thaws into water.

• When the unit operates in HEAT mode water on the heat exchanger drips off.

• The sound comes from the fan or compressor relay switching on or off.

• When defrosting is started or stopped this sound is given out. Refrigerant flowing in the reverse direction causes this to happen.

■

Troubleshooting

Condition

Indoor unit does not deliver air.

Troubleshooting

• In HEAT mode, air delivery is delayed until the indoor heat exchanger reaches the correct temperature. (Within 2 minutes.)

• In HEAT mode, when the outdoor temperature is cold, frost on the outdoor heat exchanger is defrosted automatically and the indoor unit stops delivering air for 3-12 minutes. During defrost there is water or vapor given out.

• In dehumidifying mode, the indoor fan will sometimes stop, this prevents water condensation from being vaporized.

Moisture gathers on the air outlet vent.

• If the unit is operates in high humidity for a long time, moisture can condense on the air outlet grill and drip off.

Stop all operations immediately and disconnect the power plug. Contact the dealer in the following situations:

Loud or unusual sounds are given out during operation.

Unusual odors are given out during operation.

Water is leaking.

Air switch or protection switch often breaks.

Water or liquid enters into the unit.

Unusually hot power supply cord or power plug.

Stop operation and disconnect the power plug.

Do not use an extension cord. Do not put other loads on the power supply, use a dedicated power circuit.

(Failure to do so may cause abnormal heat, electric shock or fi re.)

• Use the specifi ed types of wires for electrical connections between the indoor and outdoor units.

Firmly clamp the interconnecting wires so their terminals receive no external stresses.

Incomplete connections or clamping may cause terminal overheating or fi re.

• After connecting interconnecting and supply wiring be sure to shape the cables so that they do not put undue force on the electrical covers or panels.

Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock, or fi re.

• If any refrigerant has leaked out during the installation work, ventilate the room.

(The refrigerant produces a toxic gas if exposed to fl ames.)

• After all installation is complete, check to make sure that no refrigerant is leaking out.

(The refrigerant produces a toxic gas if exposed to fl ames.)

• When installing or relocating the system, be sure to keep the refrigerant circuit free from substances other than the specifi ed refrigerant (R22), such as air. (Any presence of air or other foreign substance in the refrigerant circuit causes an abnormal pressure rise or rupture, resulting in injury.)

18

• During pump-down, stop the compressor before removing the refrigerant piping.

If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the refrigerant piping is removed, causing abnormal pressure in the freezer cycle which will lead to breakage and even injury.

• During installation, attach the refrigerant piping securely before running the compressor.

If the compressor is not attached and the stop valve is open during pump-down, air will be sucked in when the compressor is run, causing abnormal pressure in the freezer cycle which will lead to breakage and even injury.

NOTE:

If you find the electrical wiring is of insufficient length for correct installation, please contact an authorized service shop.

• The electric wiring must be correctly connected. Incorrect connection can cause spare parts to

malfunction.

• Tighten the terminal screw correctly.

• After tightening the screw, lightly pull the wire to confirm that it is firmly in place.

• If the ground wire is incorrectly connected, there is danger of electric shock.

• The cover plate must be attached, and the connection must be tight. Incorrect installation can

let moisture enter in, which increases the danger of fire or electric shock.

right side of the indoor unit, you can cut off the

frame tailings if necessary. (Show in Fig.7)

(1) Cut off tailings 1 when routing the wiring only;

(2) Cut off tailing 1 and tailing 2 when routing both the wiring and piping.

2. Remove the piping from the body case, wrap the

piping electrical wiring and water pipe with tape

and pull them through the piping hole. (See Fig.8)

3. Hang the mounting slots for the indoor unit on the

upper tabs of the rear panel and check if it is

correctly attached. (See Fig.9)
