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.
Before starting the air conditioner, read the
information given in the User's Guide caref-
ully. The User's Guide contains very impor-
tant observations relating to the assembly,
operation and maintenance of the air
conditioner.
The manufacturer does not accept respon-

Always remember to unplug the air
conditioner before openning inlet grill. Never
unplug your air conditioner by pulling on
the power cord. Always grip plug firmly and
pull straight out from the outlet.
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 conditioner.
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.

start of the compressor(Technical Process)
and the adversely influence caused by
the 2nd harmonies of compressor following
installation conditions do apply:
1.The power connection for air conditioner
has to be done at the main power
distribution.This distribution has to be of a
Iow impedance. Normally the required
impedance is reached at a 32A fusing point.
2.No other equipment has to be connected:
to this power line.
3.For the details installation acceptance
please refer to your contract with the power
supplier, if restrictions do apply for products:
like washing machines,air conditioners or

Operation
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 7 m 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 receivering the signals
so the distance to the indoor unit should be shorter.
Loading of the battery
Load the batteries as illustrated. 2 R-03 batteries,
resetting key (cylinder)
Remove the battery cover:
Slightly press " " and push down the cover.
Load the battery:
Be sure that the loading is in line with the" + "/"-"

The air purifying filter of the bacteria-killing medium and the multi-lights
touching intermediary purifying filter accessories with machine will be used
based on real situation.
The green aspect of the bacteria-killing medium air purifying filter will face outside,
the white aspect will face to the machine.
The bacteria-killing medium air purifying filter is available for a long time and
need not to be changed. But it must be noticed to use the vacuum cleaner
frequently to adsorb the dusts covering the purifying filter lest the covering dusts
effect the function of the bacteria-killing medium air purifying filter. (It is strictly
prohibited for the bacteria-killing medium air purifying filter to be washed).
The air purifying filter of multi-lights touching intermediary will be solarized in fixed
time. In normal family , it will be solarized every 6 months.The solarization time will
last no less than 8 hours under the state of abundant sun.

During unit operation or at stop, a swishing
or gurgling noise may be heard. At first 2-3
minutes after unit start, this noise is more
noticeable. (This noise is generated by
refrigerant flowing in the system.)
During unit operation, a cracking noise may
be heard. This noise is generated by the
casing expanding or shrinking because of
temperature changes
Should there be a big noise from air flow in
unitoperation,airfilter may be too dirty.
This is because the system circulates smells
from the interior air such as the smell of
furniture,cigarettes.
During COOL or DRY operation, indoor unit
may blow out mist. This is due to the sudden
