Disposal of the old air conditioner
Before disposing an old air conditioner
that goes out of use, please make sure it's
inoperative and safe. Unplug the air
conditioner in order to avoid the risk of
child entrapment.
It must be noticed that air conditioner
system contains refrigerants, which require
specialized waste disposal. The valuable
materials contained in a air conditioner can
be recycled. Contact your local waste
disposal center for proper disposal of an
old air conditioner and contact your local
authority or your dealer if you have any
question. Please ensure that the pipework
of your air conditioner does not get
damaged prior to being picked up by the
relevant waste disposal center, and
contribute to environmental awareness by
insisting on an appropriate, anti-pollution
method of disposal.
Disposal of the packaging of your new
air conditioner
All the packaging materials employed in
the package of your new air conditioner
may be disposed without any danger to the
environment.
The cardboard box may be broken or cut
into smaller pieces and given to a waste
paper disposal service. The wrapping bag
made of polyethylene and the polyethylene
foam pads contain no fluorochloric
hydrocarbon.
Consult your local authorities for the name and
address of the waste materials collecting
centers and waste paper disposal services
nearest to your house.
Safety Instructions and Warnings
Before starting the air conditioner, read the
information given in the User's Guide

tubes with sharp or pointed items, crushing
or twisting any tubes, or scraping the
coatings off the surfaces. If the refrigerant
spurts out and gets into eyes, it may result
in serious eye injuries.
Do not obstruct or cover the ventilation
grille of the air conditioner. Do not put
fingers or any other things into the
inlet/outlet and swing louver.
Do not allow children to play with the air

When in use, put the signal transmission head directly to the receiver hole on the indoor unit.
The distance between the signal transmission head and the receiver hole should be within 7m
without any obstacle as well.
Don't throw the controller, prevent it from being damaged.
When electronic-started type fluorescent lamp or change-over type fluorescent lamp or wireless
telephone is installed in the room, the receiver is apt to be disturbed in receiving the signals so
the distance to the indoor unit should be shorter.

Remove the battery cover :
Slightly press " " and push down the cover.
Load the battery :
Be sure that the loading is in line with the " + " / " - " pole request as

helpful for a better air circulation.
Be careful not to catch a cold when cold air blows downward.
It is harmful to your health in summer to go frequently in and out of places where temp.
differenceis above 7 C . Temp. difference of 3-5 C will remove your fatigue.
More than this, unit's load can be reduced and power consumption cut down as well. So, you'd
