3. If the fuse on PC board is broken please change it with the type of T. 3.15A/250V.
4. The distance between the indoor unit and the floor should be more than 2m.
5. The wiring method should be in line with the local wiring standard.
6. After installation, the power plug should be easily reached.
7. The waste battery should be disposed properly.
8. The appliance is not intended to use by young children or infirm persons without supervision.
9.Young children should be supervised ensure that they do not play with the appliance.
10.The appliance must be installed on strong enough supporter.
11.The wiring diagram is attached inside the machine.
12.Through poor conditions of the electrical MAINS, shortly voltage drops can appear when
starting the EQUIPMENT. This can influence other equipment (eg. Blinking of a lamp).
If the MAINS-IMPEDANCE Zmax=0.18+0.11j, such disturbances are not expected. (In case of
need, you may contact your local supply authority for further information).

BRIEF INTRODUCTION TO HEALTH OPERATION
The anion generator in the air conditioner can generate a lot of anion to
effectively balance the quantity of position and anion in the air and also to kill
bacteria and speed up the dust sediment in the room and finally clean the air
in the room.
NOTE: Cooling only unit do not have displays and functions related with heating
Hints
After replacing with new batteries, remote controller will conduct self-check, displaying
all information on LCD. Then, it will become normal.

Operation
Remote controller's 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 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 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.

Note:
Use two new same-typed batteries when loading.
If the remote controller can't run normally or doesn't work at all,
use a sharp pointed item to press the reset key.
Hint:
Remove the batteries in case unit won't be in usage for a long period.
If there are any display after taking-out just need to press reset key.
Power failure resume(please set and apply as necessary)
If sudden power failure occurs, the unit will resume original operation when power is
supplied again.
Note: When sudden power failure happens during unit operation in power failure resume mode, if
the air conditioner is not desired for use in a long period, please shut off the power supply
in case that the unit automatically resume operation when power is re-supplied, or press
ON/OFF to turn off the unit when power resumes.

Cautions:
Cautions:
It is advisable not to keep vertical flap at
downward position for a long time in COOL
or DRY mode, otherwise, condensate
water might occur.
When humidity is high, condensate water
might occur at air outlet if all horizontal
louvers are adjusted to left or right.
Cautions:
(6) Unit stop
Unit won't restart until 3 minutes have
elapsed, due to system protection.
HEAT mode is not available on
cooling only unit.
Press ON/OFF button.
Only time remains on LCD.
All indicators on indoor unit go out.
Vertical flap closes automatically.
Hints
As cold air flows downward in COOL mode, adjusting air flow horizontally will be much more
helpful for a better air circulation.
As warm air flows upward in HEAT mode, adjusting air flow downward will be much more
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.
difference is above 7oC. Temp. difference of 3-5oC will remove your fatigue.
More than this, unit's load can be reduced and power consumption cut down as well. So, you'd
better set a temp. difference of 3-5oC between indoor and outdoor temp. in COOL mode.

Maintenance
Different models have different appearance
Cleaning of unit casing
Cut off power supply
before cleaning unit casing with soft cloth.
In case of heavy stain, clean it with neutral detergent.
squeeze water in the cloth, wipe off the detergent on unit
casing completely.
Cleaning of remote controller
Don't use water to wash unit casing, please use dry cloth.
Don't use glass cleaner or cloth soaked with chemicals.
Cleaning of air filter
Air Filter
1.Open inlet grille by pulling it upward. 2.Remove air filter
Push up the filter's center tab
slightly until it is caesura of
the stopper. Remove it by
pulling down.
3.Clean the filter
Use a vacuum
cleaner to remove
dust,or wash the
filter with water.
After washing,
dry the filter
completely in the shade.
4.Attach the filter
Attach filter behind the stopper so that
the "Front" indication is facing to the front. Make sure
that it is completely behind the stopper, otherwise
problems might occur.
5.Close the inlet grille.

Maintenance
Better use of air conditioner
Proper room temperature.

Once every
two weeks
Proper
temperature
Effective use of the timer.
Closing of doors and windows
during operation
Curtains or blinds
for windows
Avoid time-wasteful
operation
Never fail to observe the followings
Do not sprinkle water over
the unit.
Do not block the inlet or outlet.
Do not pull power plug.
Do not use for other purposes.
Such as food preservation
plant cultivation or animal
breeding.
14
Trouble shooting
Before asking for service, check the following first.
Phenomenon
Cause or check points
The system does not restart
immediately.
When unit is stopped, it won't restart
immediately until 3 minutes have elapsed
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.)
Noise is heard
Normal
Performance
inspection
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.
Smells are generated.
Mist or steam are blown out.
During COOL or DRY operation, indoor unit
may blow out mist. This is due to the sudden
cooling of indoor air.
Does not work at all.
Poor cooling
Is power plug inserted?
Is there a power failure?
Is fuse blown out?
Multiple
check
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?
Application temp. range of air conditioner -7oC~43oC.
