Basic cooling functions
Basic heating 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.
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.

Troubleshooting
CAUTION
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 Troubleshooting
• As a precaution, operation cannot be
resumed for approximately 3 minutes after
the air conditioner has stopped.
• 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.
• 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.
• This is caused by deformation of the plastic
due to changes in temperature.
There is a delay in operation after the air
conditioner has started.
An unusual smell is coming from the air
conditioner.
Sound of water flowing heard during
operation.
Sometimes mist comes out of the air outlet vent
in COOL mode.
Creaking noise heard during start or stop.

• 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 unit does not operate.
Cooling (Heating) effect is not sufficient.
Remote controller does not operate.
Water leakage in the room.
Water leakage is coming from the outdoor
unit.
• 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.
Noise is coming from the indoor unit.

Troubleshooting
Condition 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.
• 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:
Indoor unit does not deliver air.
Moisture gathers on the air outlet vent.
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.

Safety Precautions
Read these Safety Precautions carefully to ensure correct installation.•
This manual classifies the precautions into WARNING and CAUTION.•
Be sure to follow all the precautions below: they are all important for ensuring safety.
WARNING CAUTION
Failure to follow any of WARNING is likely to
result in such grave consequences as death or
serious injury.
Failure to follow any of CAUTION may result in
grave consequences in some cases.
The following safety symbols are used throughout this manual:•
Be sure to observe this instruction. Be sure to establish an earth connection.
Never attempt.
After completing installation, test the unit to check for installation errors. Give the user adequate•
instructions concerning the use and cleaning of the unit according to the Operation Manual.
WARNING
Installation should be left to the dealer or another professional.•
Improper installation may cause water leakage, electrical shock, or fire.
Install the air conditioner according to the instructions given in this manual.•
Incomplete installation may cause water leakage, electrical shock, or fire.
Be sure to use the supplied or specified installation parts.•
Use of other parts may cause the unit to come to lose, water leakage, electrical shock, or fire.
Install the air conditioner on a solid base that can support the weight of the unit.•
An inadequate base or incomplete installation may cause injury in the event the unit falls off the base.
Electrical work should be carried out in accordance with the installation manual and the national•
electrical wiring rules or code of practice.
Insufficient capacity or incomplete electrical work may cause electrical shock or fire.
Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance.•
For wiring, use a cable length enough to cover the entire distance with no connection.•
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 fire.)
Use the specified 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 fire.
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 fire.
If any refrigerant has leaked out during the installation work, ventilate the room.•
(The refrigerant produces a toxic gas if exposed to flames.)
After all installation is complete, check to make sure that no refrigerant is leaking out.•
(The refrigerant produces a toxic gas if exposed to flames.)
When installing or relocating the system, be sure to keep the refrigerant circuit free from substances•
other than the specified 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.)

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.
Be sure to establish an earth. Do not earth the unit to a utility pipe, arrester, or telephone earth. •
Incomplete earth may cause electrical shock, or fire. A high surge current from lightning or
other sources may cause damage to the air conditioner.
Be sure to install an earth leakage breaker. Failure to install an earth leakage breaker may result in•
electric shocks, or fire.
CAUTION
Do not install the air conditioner in a place where there is danger of exposure to inflammable•
gas leakage.
If the gas leaks and builds up around the unit, it may catch fire.
Establish drain piping according to the instructions of this manual. Inadequate piping may cause•
flooding.
Tighten the flare nut according to the specified method such as with a torque wrench.•
If the flare nut is tightened too hard, the flare nut may crack after a long time and cause refrigerant
leakage.
Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a•
shelter by small animals.
Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please
instruct the customer to keep the area around the unit clean.
