1. Precaution
1.1 Safety Precaution
To prevent injury to the user or other people and
property damage, the following instructions must
be followed.
Incorrect operation due to ignoring instruction
will cause harm or damage.
Before service the unit, be sure to read this
service manual at first.
1.2 Warning
Installation
Do not use a defective or underrated circuit
breaker. Use this appliance on a dedicated circuit.
There is risk of fire or electric shock.
For electrical work, contact the dealer, seller, a
qualified electrician, or an authorized service center.
Do not disassemble or repair the product, there is risk of
fire or electric shock.
Always ground the product.
There is risk of fire or electric shock.
Install the panel and the cover of control box
securely.
There is risk of fire of electric shock.
Always install a dedicated circuit and breaker.
Improper wiring or installation may cause fore or electric
shock.
Use the correctly rated breaker of fuse.
There is risk of fire or electric shock.
Do not modify or extend the power cable.
There is risk of fire or electric shock.
Do not install, remove, or reinstall the unit by
yourself (customer).
There is risk of fire, electric shock, explosion, or injury.
Be caution when unpacking and installing the
product.
Sharp edges could cause injury, be especially careful of
the case edges and the fins on the condenser and
evaporator.
For installation, always contact the dealer or an
authorized service center.
Do not install the product on a defective
installation stand.
Be sure the installation area does not deteriorate
with age.
If the base collapses, the air conditioner could fall with it,
causing property damage, product failure, and personal
injury.
Do not let the air conditioner run for a long time
when the humidity is very high and a door or a
window is left open.
Take care to ensure that power cable could not be
pulled out or damaged during operation.
There is risk of fire or electric shock.
Do not place anything on the power cable.
There is risk of fire or electric shock.
Do not plug or unplug the power supply plug
during operation.
There is risk of fire or electric shock.
Do not touch (operation) the product with wet
hands.
Do not place a heater or other appliance near the
power cable.
There is risk of fire and electric shock.
Do not allow water to run into electrical parts.
It may cause fire, failure of the product, or electric shock.
Do not store or use flammable gas or combustible
near the product.
There is risk of fire or failure of product.
Do not use the product in a tightly closed space
for a long time.
Oxygen deficiency could occur.
When flammable gas leaks, turn off the gas and
open a window for ventilation before turn the
product on.
If strange sounds or smoke comes from product,
turn the breaker off or disconnect the power supply
cable.
There is risk of electric shock or fire.
Stop operation and close the window in storm or
hurricane. If possible, remove the product from the
window before the hurricane arrives.
There is risk of property damage, failure of product, or
electric shock.
Do not open the inlet grill of the product during
operation. (Do not touch the electrostatic filter, if the
unit is so equipped.)
There is risk of physical injury, electric shock, or product
failure.

When the product is soaked, contact an
authorized service center.
There is risk of fire or electric shock.
Be caution that water could not enter the product.
There is risk of fire, electric shock, or product damage.
Ventilate the product from time to time when
operating it together with a stove etc.
There is risk of fire or electric shock.
Turn the main power off when cleaning or
maintaining the product.
There is risk of electric shock.
When the product is not be used for a long time,
disconnect the power supply plug or turn off the
breaker.
There is risk of product damage or failure, or unintended
operation.
Take care to ensure that nobody could step on or
fall onto the outdoor unit.
This could result in personal injury and product damage.
CAUTION
Always check for gas (refrigerant) leakage after
installation or repair of product.
Low refrigerant levels may cause failure of product.
Install the drain hose to ensure that water is
drained away properly.
A bad connection may cause water leakage.
Keep level even when installing the product.
It can avoid vibration of water leakage.
Do not install the product where the noise or hot
air from the outdoor unit could damage the
neighborhoods.
It may cause a problem for your neighbors.
Use two or more people to lift and transport the
product.
Do not install the product where it will be exposed
to sea wind (salt spray) directly.
It may cause corrosion on the product. Corrosion,
particularly on the condenser and evaporator fins, could
cause product malfunction or inefficient operation.
Operational
Do not expose the skin directly to cool air for long
time. (Do not sit in the draft).
Do not use the product for special purposes,
such as preserving foods, works of art etc. It is a
consumer air conditioner, not a precision
refrigerant system.
There is risk of damage or loss of property.
Do not block the inlet or outlet of air flow.
Use a soft cloth to clean. Do not use harsh
detergents, solvents, etc.
There is risk of fire, electric shock, or damage to the
plastic parts of the product.
Do not touch the metal parts of the product when
removing the air filter. They are very sharp.
Do not step on or put anything on the product.
(outdoor units)
Always insert the filter securely. Clean the filter
every two weeks or more often if necessary.
A dirty filter reduces the efficiency of the air conditioner
and could cause product malfunction or damage.
Do not insert hands or other objects through air
inlet or outlet while the product is operated.
Do not drink the water drained from the product.
Use a firm stool or ladder when cleaning or
maintaining the product.
Be careful and avoid personal injury.
Replace the all batteries in the remote control
with new ones of the same type. Do not mix old and
new batteries or different types of batteries.
There is risk of fire or explosion.
Do not recharge or disassemble the batteries. Do
not dispose of batteries in a fire.
They may burn of explode.
If the liquid from the batteries gets onto your skin
or clothes, wash it well with clean water. Do not use
the remote of the batteries have leaked.
