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
entrapment.
It must be noticed that air conditioner
system contains refrigerants, which require
specialized waste disposal. The valuable
materials contained in an air conditioner
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
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.

Safety Instructions and Warnings
Before starting the air conditioner, read the
information given in the User's Guide
carefully. The User's Guide contains very
important observations relating to the
assembly , operation and maintenance of
the air conditioner.
The manufacturer does not accept
responsibility for any damages that may
arise due to non-observation of the following
instruction.
Damaged air conditioners are not to be
put into operation. In case of doubt, consult
your supplier.
Use of the air conditioner is to be carried
out in strict compliance with the relative
instructions set forth in the User's Guide.
Installation shall be done by professional
people, don't install unit by yourself.
For the purpose of the safety,the air conditioner
must be properly grounded in accordance
with specifications.
All the packaging materials employed in
package of your new air conditioner may
disposed without any danger to the
environment.
The cardboard box may be broken or cut
smaller pieces and given to a waste paper
disposal service. The wrapping bag made of
polyethylene and the polyethylene foam pads
All these valuable materials may be taken
to a waste collecting center and used again
after adequate recycling.
Consult your local authorities for the name
and address of the waste materials
collecting centers and waste paper disposal
services nearest to your house.
the
be
into
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 performating 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.

Maintenance
Cleaning of the unit
Turn off the power switch
Take off the air inlet grill
First switch off the power supply,take off the
screw cap,loosen the screw with cross screwdriver .
Clean the filter
Use water or vacuum cleaner to remove
dust. If it is too dirt, clean with detergent or
neutral soap water.
Rinsing with fresh water, dry the filter and
re-assemble.
Caution:
Do not wash filter in hot water above 40∞C,
which will damage the filter.
Do carefully wipe the filter.
Clean the indoor(outdoor) unit
Clean with warm cloth or neutral detergent,
then wipe away moisture with dry cloth. Do
not use too hot water(above 40∞C),which will
cause discoloration or deformation. Do not
use pesticide or other chemical detergents.
Do not touch with wet hand
Do not clean with hot
water or solvent
Maintenance at the end of application season
On a fine day, unit shall be started and operate in
FAN mode for about half a day until the inside of
the unit becomes thoroughly dry.
Turn off the unit operation switch and power on/off.
Otherwise,there will be some electricity consumption
even the unit is in stop status.
Clean the filter and indoor,cover the units well.
Maintenance before beginning of application season
Check there are no obstacles in the air
inlet and
outlet to avoid impairing of working
efficiency.
Please do attach the air filter to ensure the
electrostatic filters not soiled.Otherwise,dirt
will come into and damage the unit or bring
failures.

Trouble shooting
Before asking for service, check the following first.
Cause or check pointsPhenomenon
Normal
Performance
inspection
The system does not restart
immediately.
Noise is heard:
Smells are generated.
Mist or steam are blown out.
When unit is stopped, it won't restart
immediately until 3 minutes have elasped
to protect the system.
When the electric plug is pulled out and
reinserted, the protection circuit will work
for 3 minutes to protect the air conditioner.
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
unit operation, air filter 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
cooling of indoor air.
Multiple
check
Does not work at all.
Poor cooling
Is power plug inserted?
Is there a power failure?
Is fuse blown out?
Is the air filter dirty? Normally it should be
cleaned every 15 days.
Are there any obstacles before inlet and outlet?
Is temperature set correctly?
Are there some doors or windows left open?
Is there any direct sunlight through the
window during the cooling operation?(Use
curtain)
Are there too much heat sources or too many
people in the room during cooling operation?

selection of installation place
Place where it is easy to route drainage pipe
and outdoor piping.
Place ,away from heat source and with less
direct sunlight.
Place where cool and warm air could be
delivered evently to every corner of the room.
Place near power supply socket.Leave enough
space around the unit.
Place ,robust not causing vibration,where the
body can be supported sufficiently.
To prevent interference, place it at least 1m
away from other electric machines, such as
TV set, radio.
Installing
According to the dimension of the figure 2 shown,
nail two cement steel nails on the wall,Keep 2~3
mm out.then hang the back of the unit on them.
There must be no gap between the indoor unit
and wall.
Remove the front panel,then use two expansible
screws to fix the unit on the floor.As figure 3
shown.
Once refrigerant piping and drain piping connections
are complete,fill the gap of the throght hole with putty.
Attach the front panel and front grille in their orginal
positions once all connections are complete.

Resumable failures are marked with " ", the others are not resumable failures.
Resumable failure will disappear when the failure is eliminated and its failure code
will disappear automatically within 30 seconds. But the other failure code will
disappear only after the unit starts up once again.
When failure occurs, the unit only can receive "OFF" signal from the controller.
And when the unit is shut off, the failure code will disappear.
