1. PRECAUTIONS
■ Ensure when installing National Regulations are complied with.
Failure to do so, could cause damage or injury.
■ Read "PRECAUTIONS" carefully before installation.
■ The following precautions include important safety items.
■ Keep this manual with the owner's manual for future reference.
The safety precautions listed here are divided into two categories. In
either case, important safety information is listed which must be read
carefully prior to installing or servicing.
WARNING
Failure to observe a warning may result in injury.
CAUTION
Failure to observe a caution may result in injury or damage to
the equipment.
After completing the installation, make sure that the unit operates
properly during the start-up operation. Please instruct the customer
on how to operate the unit and keep it maintained.Also, inform customers that they should store this installation manual along with the
owner's manual for future reference.
WARNING
Only trained and qualified service personnel to install,
repair or service the equipment.
Incorrect installation, repair, and maintenance may result in
electric shocks, short-circuit, leaks, fire or other damage to
the equipment.
CONTENTS PAGE Install according to this installation instructions only.
If the installation is defective, it will cause water leakage, electrical
shock and fire.
When installing the unit in a small room, take measures against to
stop refrigerant concentration from exceeding allowable safety
limits in the event of refrigerant leakage.
Contact your installer immediately should this happen. Excessive
refrigerant in a closed ambient can lead to oxygen deficiency.
Use the enclosed parts and specified parts for installation,
Failure to do so could cause the set to fall, water leakage, electrical
shock fire.
If the wall is not sufficient to hold the units weight, this could cause
the unit to drop and result in injury.
The appliance must be installed 2.3m above the floor.
The appliance shall not be installed in the laundry.
Before obtaining access to electrics, all supply circuits must be
disconnected.
For electrical work, follow the local national a separate electrical,
regulation and this installation manual. An independent circuit and
single outlet must be used.
If the electrical circuit capacity is not enough or defect in electrical
work, it will cause an electrical shock and fire.
Only use the specified cable and ensure the cable is connect tightly
and clamp the cable so that no external force will be acted on the
terminal.
If the connection or fixing is not perfect, it will cause heat-up or fire at
the connection.
Wiring routing must be properly arranged so that control board
cover is fixed properly.
If control board cover is not fixed perfectly, it will cause heat-up at
connection point of terminal, possibly causing a fire or electrical shock.
If the supply cord is damaged, it must be replaced by the
manufacture or its sevice agent or a similarly qualified person in
order to avoid a hazard.
An all-pole disconnection swith having a contact separation of at
least 3mm in all poles should be connected in fixed wiring.
When carrying out piping connection, take care not to let air
substances go into refrigeration cycle.
Otherwise, it will cause lower capacity, abnormal high pressure in the
refrigeration cycle, explosion and injury.
Do not modify the length of the power supply cable or use of
extension cable, and do not share the single outlet with other
electrical appliances.
Otherwise, it will cause fire or electrical shock.
The temperture of refrigerant circuit will be high, please keep the
interconnection cable away from the copper tube.

PRECAUTIONS | 3
Only carry out work on the unit in suitable weather conditions.
Improper installation work may result in the equipment falling
and causing accidents.
If the refrigerant leaks during installation, ventilate the
area immediately.
Toxic gas may be produced if the refrigerant comes into
contact with a naked flame.
After completing the installation work, check that the
refrigerant does not leak.
Toxic gas may be produced if the refrigerant leaks into the
room and comes into contact with a naked flame, such as a
fan heater, stove or cooker.
CAUTION
Ground the air conditioner.
Do not connect the ground cable to gas or water
pipes,lightning rod or a telephone ground cable. Incomplete
grounding may result in electric shocks.
Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in
electric shocks.
Connect the outdoor unit cables, then connect the
indoor unit wires.
You are not allowed to connect the air conditioner with the
power source until wiring and refrigeration to the air conditioner is complete.
While following the instructions in this installation
manual, install drain piping in order to ensure proper
drainage and insulate piping in order to prevent condensation.
Improper drain piping may result in water leakage and
property damage.
Install the indoor and outdoor units, power supply cables
and connecting cables at least 1m away from televisions
or radios in order to prevent image interference or noise.
Depending on the radio waves, a distance of 1 metre may
not be sufficient enough to eliminate the noise.
The appliance is not intended for use by young children
or infirm persons without supervision.
Don't install the air conditioner in the following locations:
■ There is petrolatum existing.
■ Salty environment i.e (near the coast).
■ There is caustic gas (the sulfide, for example) existing
in the air.
■ The Volt vibrates violently (in the factories).
■ In kitchens where it is full of oil gas.
■ There is strong electromagnetic wave existing.
■ There are inflammable materials or gas.
■ There is acid or alkaline liquid evaporating.
■ Other special conditions.
2. INSTALLATION INFORMATION
To install properly, please read this "installation manual" first.
The air conditioner must be installed by qualified persons.
When installing the indoor unit or its tubing, please follow this
manual as strictly as possible.
If the air conditioner is installed on a metal part of the building, it
must be electrically insulated according to the relevant standards
to electrical appliances.
When all the installation work is finished, please turn on the
power only after a thorough check.

range.
■ Keep the remote controller at least 1m apart from the nearest TV set or stereo equipment.
(it is necessary to prevent image disturbances or noise interferences.)
■ Do not install the remote controller in a place exposed to direct sunlight or close to a
heating source, such as a stove.
■ Insert the batteries in the correct order.
