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

 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.

3
 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
