1. Use a power supply with a 220-240 volt (±10%) rating.
Use of a power supply with improper voltage and frequency can result in equipment
damage and possible fire.
2. Open a window or door periodically to ventilate the room, especially when using gas
appliances.
3. Never insert objects into the unit. Inserting objects can result in injury due to the high speed
rotation of internal fans.
4. Do not pull the power cord. Pulling and misuse of the power cord can result in damage to
the unit and cause electrical shock.
5. When using the air conditioner in a room where infants, children, elderly people, or
bedridden or disabled people are present, make sure the room temperature is suitable for
them.
ENGLISH
6. Make sure a fuse with the correct current rating is installed.
7. Follow the local rules and regulations for power cord cabling. Improper cable connection
can cause the power cord, plug and the electrical outlet to overheat and cause a fire.
8. For safety, turn off the circuit breaker or disconnect the power cord when the unit is not
used for an extended period of time.
This unit is designed for use in residences. Do not use for other applications such as
in a kennel or greenhouse to raise animals or grow plants.
LOCATION
» Install the unit in a place with minimal dust, fumes and moisture in the air.
REMOVAL
» Do not attempt to remove the unit. Consult your dealer or other qualified service personnel
for the removal of the unit.
This equipment complies with the requirements of Directives 89/336/EEC and 73/23/EEC as
amended by 93/68/EEC.

WHEN A POWER FAILURE OCCURS
This air conditioner has a memory function to store settings when a power failure occurs.
After power recovery, the unit will automatically re-start in the same settings which were active before
the power failure, except for timer settings.
If the timers were set before a power failure, they will need to be re-set after power recovery.
PREHEATING FUNCTION
In the HEAT operation, the indoor fan may not start for two to five minutes after the unit is turned on
to prevent cold air from blowing out of the unit.
DE-ICING FUNCTION
» When ice forms on the heat exchanger in the outdoor unit during the HEAT operation, the
automatic de-icer provides heat for about 5 to 10 minutes to remove the ice. During de-icing, the
inside and outside fans stop operating.
» After de-icing is completed, the unit automatically resumes operation in the HEAT mode.
» The built-in protective
device may prevent the
unit from operating when
used out of this range.
» Condensation may form
on the air outlet if the
unit operates continuously in the COOL or
DRY mode when humidity is over 80 percent.
ENGLISH
HEATING EFFICIENCY
» The unit uses a heat pump to obtain heat from the outside air and releases it into the room. The
outside air temperature therefore greatly affects the heating efficiency.
» If the heating efficiency is reduced due to low outside temperatures, use an additional heater.
» It takes time to warm up and heat the entire room because of the forced air circulation system.
TIPS ON SAVING ENERGY
Below are some simple ways to save energy when you use your air conditioner.
SET THE CORRECT TEMPERATURE
» Setting the thermostat 1°C higher than the desired temperature in the COOL mode and 2°C lower
in the HEAT mode will save approximately 10 percent in power consumption.
» Setting the temperature lower than necessary during cooling operation will result in increased
power consumption.
BLOCK DIRECT SUNLIGHT AND PREVENT DRAFTS
» Blocking direct sunlight during cooling operation will reduce power consumption.
» Close the windows and doors during cooling opeation and heating operation.
SET PROPER AIR FLOW DIRECTION TO OBTAIN THE BEST AIR
CIRCULATION
KEEP FILTERS CLEAN TO ENSURE THE MOST EFFICIENT OPERATION
MAKE MOST OF THE TIMER OFF FUNCTION
DISCONNECT THE POWER CORD WHEN THE UNIT IS NOT USED FOR AN
EXTENDED PERIOD OF TIME
» The indoor unit still consumes a small amount of power when it is not operating.

The air filters should be cleaned every two weeks.
1 Open the front panel.
2 Push the air filters up slightly to unlock them.
3 Pull the air filters down to remove them.
Use a vacuum cleaner to remove dust. If the
filters are dirty, wash them with warm water
and a mild detergent. Dry filters in the shade
before reinstalling.
1 Reinstall the filters in the original positions.
2 Close the front panel.
3 Push the centre part of the panel firmly to
lock it in place.
CLEANING THE UNIT AND THE REMOTE CONTROL
» Wipe them with a soft cloth.
» Do not directly splash or pour water on them. Water can cause electrical shock or
equipment damage.
» Do not use hot water, thinner, abrasive powders or strong solvents.
MAINTENANCE AFTER AIR
CONDITIONER SEASON
1 Operate the unit in the FAN
ONLY mode for about half a day
to allow the mechanism to thoroughly dry.
2 Stop the operation and unplug
the unit. Turn off the circuit
breaker, if you have one exclusively for the air conditioner.
MAINTENANCE BEFORE
AIR CONDITIONER SEASON
1 Make sure that the air filters are
not dirty.
2 Make sure that nothing obstructs
the air inlet or outlet.
3 Check the outdoor mounting rack
periodically for wear and to make
sure it is firmly in place.
3 Clean the filters, then reinstall
them.

BEFORE CALLING FOR SERVICE
The following conditions do not denote equipment malfunctions
UNIT DOES NOT OPERATE
The unit will not operate if it is
turned on immediately after it is
turned off. The unit will not operate
immediately after the mode is
changed. This is to protect the
internal mechanisms. Wait 3
minutes before operating the unit.
UNIT DOES NOT SEND OUT
WARM AIR
The unit is preheating or de-icing.
ODORS
Carpet and furniture odors that entered into the unit and the air conditioner's inner component odors at
the early stage of installation may
be sent out from the unit.
CRACKING NOISE
The unit may produce a cracking
noise. This sound is generated by
the friction of the front panel and
other components expanding or
connecting due to a temperature
change.
SWISHING NOISE
The soft, swishing noise is the sound of the
refrigerant flowing inside the unit.
WATER VAPOUR
» In the COOL and DRY operation, water
vapour can sometimes be seen at the air
outlet due to the difference between the
room air temperature and the air discharged by the unit.
» In the HEAT operation, water vapour may
flow out of the outdoor unit during deicing.

If the unit appears to be malfunctioning, check the following points before calling for
service.
IF THE UNIT FAILS TO OPERATE
Check to see if the circuit breaker has tripped or the fuse has blown.
IF THE UNIT FAILS TO COOL OR HEAT THE ROOM EFFECTIVELY
Check the filters. If dirty,
clean them.
Make sure windows and
doors are closed tightly.
Check the outdoor unit to
make sure nothing is
blocking the air inlet or
outlet.
A large number of people
in the room can prevent
the unit from achieving the
desired temeperature.
Check the thermostat is
for proper setting.
Check whether any
heat-generating appliances are operating in
the room.

window.
Check whether the remote control batteries
are installed with the
polarities properly
