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

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

PRECAUTION
Version - 1 4 DCH DCI
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

PRECAUTION
