Operation for comfort and economy
Do not overcool the room.
This Is not good for health and
waste electricity.
Keep blinds or curtains
closed.
Do not let sunshine enter
the room directly when the air
conditioner is in operation.
Keep the room temperature
uniform.
Adjust the verticai and horizontal
airflow direction to ensure a
uniform temperature in the room.
Make sure that the doors and Clean the air filter regularly.
windows are shut tight.
Avoid opening doors and windows
as much as possible to keep the
coo! air in the room.
Blockages in the air filter reduce
the airflow and lower cooling and
dehumidifying effects. Clean at
least once every two weeks.
(See page 8).
Ventilate the room
occasionally.
Since windows are kept closed, it
is a good idea to open them and
ventilate the room now and then.

Page 8
Do not pull out the power
cord.
Damage to the cord may result in
serious electhcai shocks.
Do not use the air
conditioner for purposes
other than cooling the room.
Do not use the air conditioner for
other purposes such as drying
clothes, preserving foods, keeping
animals, or cultivating vegetables.
Do not biock the air intake
and outlet vents.
This causes lowered performance
and irregular operation. Do not
insert sticks or other objects into
these vents as it is dangerous to
touch the electric components and
the fan.
Select the most appropriate
temperature.
Take care to adjust the temperature
to suit the conditions. Rooms
occupied by infants, the elderly,
or the sick should be kept at an
appropriate temperature.
Do not use heating
apparatuses in the vicinity.
The air conditioner’s plastic parts
melt if exposed to excessive heat.
Avoid exposing the body
directiy to a continuous
unidirectionai airflow for
long periods.
This is not recommended for
health reasons.

Always turn off the air conditioner and main power supply before cleaning to ensure safety.
Air Filter
The air filter behind the intake grille should be washed
at least every two weeks or as often as it needs
cleaning.
HOW TO CLEAN THE AIR FILTER
1. To remove the air filter, grasp the tab on the filter
and pul! to the right.
2. Vacuum the filter on the dusty side to remove light
dust.
Vacuum cleaner
3. Wash the filter, cleaner side up under gently flowing
water to wash out accumulated dust and lint.
Caution
Wipe off dirt with a soft, dry cloth {use a vacuum
cleaner to remove dust from the air inlet.) Use a
cloth and water less than 40°C to remove stubborn
dirt (the cloth should be well-wrung). Do not use
the following cleansers as they cause the paint to
peel and lead to malfunctions: Benzene, thinner,
scouring powder, chemical-soaked cloths, etc.
4. If the filter is very dirty, use a mild household
detergent in the wash water.
Let the filter dry thoroughly before reinstalling it.
When reinstalling the filter, be sure the word “FRONT’
is facing you as you slide the filter back into place.
Front Grille
Clean the front grille with a clean cloth lightly dampe
ned with mild liquid dish-washing detergent.
Annual check
* After long-term usage of room air conditioners, dust
and dirt will accumulate inside, lowering the
performance. This may cause the generation of
odour or may impede the drainage of the dehumidifying
water.
* Besides regular cleaning of the air conditioner, a
separate annual check is also recommended
(chargeable). Please request your dealer to carry out
these checks.

Please read the following before insialling the Air Conditioner. Select the Best Location for the most efficient cooling.
Location
• The air conditioner should be installed in a dry place where there are no draughts.
• Condensation from the air conditioner must be drained to an appropriate location.
0 Do not install in a iocation where flammable gas leaks are a possibility.
• Using in locations where the air is salty such as beside the sea or near hot spas, or
where sulphurous gas is generated, may lead to a malfunction. Please consult your dealer.
• Ensure that the wall is strong enough to support the unit.
How to Install
There should not be any obstacles surrounding the unit.
Prepare the installation hole slightly bigger than cabinet size.
(FRONT VIEW)
1) PREPARE CHASSIS
• Remove chassis locking bracket by loosening
the screw.
• Slide the chassis out from the cabinet.
2) Place cabinet into opening and secure it by wood
screws or nails.
• The cabinet should be installed tilted slightly
lower to the rear for nescessary condensate
drainage. (Max. 10mm)
3) Slide Chassis into the cabinet which installed the
above 2).
• The tubings or ducting part should not be touched
with the cabinet.
4) Lock the chassis into cabinet by chassis locking
bracket.
5) Place FRONT GRILLE onto CABINET by screws.
• To place the grille, hook top of grille onto top of
cabinet, push bottom of grille in until it snaps
into place. Secure the Front Grille with the
screws at the right, left and centre of the grille.

Eleetrlcal work
Noise Gonsiderations
Always use at the rated voltage.
Some installation locations may require installation of
a shortcircuit breaker.
A 10 Ampere time delay fuse or circuit breaker is
required.
Nominal cross sectionai area of power supply wire
must be 3 core x 1.0 mm^ or above.
The power supply must be from an independent circuit.
All electrical installation must be made in
accordance with local wiring and safety regulations
wherever applicable.
Please consult your dealer concerning installation
requirements.
Transferring
• When repositioning the air conditioner due to
renovations, or when transferring to a different
location, the removal and re installation of the unit
requires an additional service charge. Please consult
your dealer before moving. .
RernpVal of the girille
1) REMOVE AIR FILTER
2) REMOVE FRONT GRILLE
• Loosen the screws at the right, left and centre of the
grille.
• Press the side of the cabinet firmly and at the same
time pull the corner of the grille forward to
unhook the tabs.
• Slide the grille upward to free the two tabs at the
top of the grille from slots at the top of the cabinet.
• Select an installation location that can support the
weight of the air conditioner and one that will not cause
increased operating noise and vibration.
• Ensure that airflow and noise from the rear side
of the unit (outdoors) when installed do not cause
inconvenience to neighbouring residents.
• Obstacles placed in front of the air outlet on the
rear side of the unit (outdoors), or covers placed
over it, cause excessive noise and a deterioration in
performance.
brain water
To get the maximum cooling efficiency this air
conditioner is designed to splash the condensate
on the condenser coil.
This method is called “Slinger-Up System”.
If the splashing sound annoys you, you can provide
an outside drain by using the following procedure
which may, however cause a small loss of
performance.
1. Slide out the chassis from the cabinet.
2. Remove the rubber plug from the body base plate.
(For cooling mode! only)
3. Install the drain pan prepared in the accessory kit to
the corner of the cabinet with 2 screws.
4. Connect the drain hose to the outlet on the drain pan
bottom.
5. Slide the chassis into its original place in the cabinet.
Note: Drain hose or tubing can be purchased locally to
satisfy your particular needs.

Faults
Does not operate.
Does not cool or heat effectively. Is the air fiiter dirty? See air filter cleaning instructions on page 8.
Has the fuse blown or has the circuit breaker been tripped?
Is the Main Control Knob set at Off?
Are the air intake and outlet vents on the rear side of the unit
(outdoors) blocked?
Is the air conditioner set for ventilation (the ventilation lever set
at Open) or is the Main Control Knob set at either High Fan or
Low Fan?
The Thermostat Control Knob may not be set low enough. Turn
the knob further clockwise; the indoor air should become cooler or
warmer.
The room may have been very hot when the air conditioner
was first turned on. Allow time for it to cool down or heat up.
The cooling coils have iced up. To melt the ice, turn the Main Control
Knob to FAN and the Thermostat Control Knob anti-clockwise.
The room has a peculiar odour.
Air conditioner operation is
noisy.
It seems that condensation is
leaking from the air conditioner.
Check that this is not a damp smell exuded by the walls, carpet,
furniture or cloth items in the room.
For a noise that sounds like water flowing:
This is the sound of freon circulating inside the air conditioner unit.
For a noise that sounds like a shower:
This is the sound of the dehumidifying water being processed
inside the air conditioning unit.
Condensation occurs when the airflow from the air conditioner
cools the warm room air.
