Cautions

All electrical repairs must be carried out
by qualified electricians. Inadequate repairs
may result in a major source of danger for
the user of the air conditoiner.

Do not damage any parts of the air
conditioner that carry refrigerant by piercing
or perforating the air conditioner's 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
conditioner. In no case should children be
allowed to sit on the outdoor unit.

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

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
