To reset the fi lter and removable panel
The fi lter is attached to the rear side of the removable panel.
1 Pull the bottom of the removable panel toward you.
2 Lift up the fi lter’s handle and pull out.
Cleaning
Use a vacuum cleaner to remove dust and dirt from the air
fi lter, or wash in a synthetic detergent. After washing, dry in a
shaded place, then reinstall.
To set the fi lter and removable panel

Installation procedure
Installation assistance
1) Remove the sticker from the front panel.
2) Put the unit into the installation hole.
· When installing the unit, it should be slanted down to the back to avoid
the enlargement of noise or vibration. (Slant between 6-10mm. )
(Shown at right fi gure.)
· The installation place should be strong enough to avoid the
enlargement of noise or vibration.
3) Fill in the gap around the cabinet with sponge or foam.
· Use steel support
The installation hole should be strong enough to support
the air conditioner. If it cannot, steel support has to be
used outdoors.
Steel support should be fi xed on the building (Shown at
right fi gure.)
· Use sunshade board
Avoid direct sunshine to the air conditioner. If there is no
cover on it, you should contact the seller for installing the
sunshade board. When installing the sunshade board,
don’t let it block the air inlet at the side grille.
Note:
• If there is a gap between the cabinet and the unit, seal it
with the foam.
• If the unit is used for an extended period in an environment with 80% or greater humidity, condensation may drip from the unit.

• The electric components will be damaged when the voltage is too high.
If the voltage is too low, the compressor will vibrate violently to damage the refrigerant system and easily cause the compres-
sor and electric components not work.
• The ground must be connected.
Special socket must be used. Furthermore, the socket and wiring must conform to the wiring regulations. And the earthing method
must be reliable.
In fi xed circuit, there must be electricity leakage protection switch of enough power capacity and air switch with enough space.
• The exclusive circuit must be used. But removable socket can’t be used because poor contact of it can cause over heat or fi re.
• In fi xed circuit, there must be electricity leakage protection switch and leakage current is less than 30mA.
• Air switch (thermal-magnetic breaker) should be installed in the circuit.
• If the power supply cable is damaged, it must be replaced by the manufacturer or your dealer or a qualifi ed person to avoid a
hazard.
Electricity Wiring
WARNING
• This appliance shall be installed in accordance with national wiring regulations.
• The power supply sets up the air conditioner exclusive use circuit and do not share with other
electricity product.
• Always use a separate power supply line protected by a circuit breaker operating on all wires
with a distance between contact of 3 mm for this unit.
• Please install the devices for short-circuit protection and electrical leakage protection and
circuit when installing the air conditioner.
• According to the local safety regulations, use qualifi ed power supply circuit break.

Avoid installing the air conditioner
near a fireplace or other heating
apparatus.
Exposure to excessive heat could result
in deformation of the outer case.
Do not expose the air conditioner
directly to water.
Electrical insulation could be damaged,
resulting in electrical shock.
Using the fuse in a correct wire.
It will be cause of the trouble and fi re.
PRECAUTIONS
Do not start and stop air conditioner
operation by disconnecting the
power supply cable and so on.
Put in a power plug certainly.
Don’t operate with put in a power plug
to loose consent.
Don’t connect with power supply
cable each other.
It’s very dangerous to do it by yourself.
Do not block or cover the intake grille
and outlet port.
Obstructing the ports will reduce
operating effi ciency, leading to improper
operation and possible damage.
Provided occasional ventilation
during use.
Insuffi cient ventilation could lead to
oxygen starvation.
Do not pull power supply cable.
Pulling on the cable to disconnect the
plug could damage the wires inside the
cable, resulting in heat or fi re.
Do not insert fi ngers or objects into
the outlet port or intake grilles.
●
A fan operates at high speed inside the
unit, and personal injury could result.
● Be particularly careful regarding small
children.
Do not stay in direct cooling airfl ow
for long periods.
● Excessive direct exposure to chilled
air could be bad for your health.
● Be especially careful when going to
bed, and in rooms where infants,
aged, or sick people air staying.
Always operate with the air filter
installed.
Operating the unit without the air fi lter
could cause excessive dirt to collect on
internal parts, leading to malfunction.
17
TROUBLESHOOTING
Before requesting service, perform the following checks:
Symptom Problem
NORMAL
FUNCTIONS
Doesn’t operate immediately: ● If the unit is stopped and then immediately started again, the compressor
will not operate for about 3 minutes, in order to prevent fuse blowouts.
● Whenever the power plug is disconnected and then reconnected to
a power outlet, the protection circuit will operate for about 3 minutes,
preventing unit operation during that period.
Noise is heard:
● During operation and immediately after stopping the unit, the sound of
water fl owing in the air conditioner’s piping may be heard. Also, noise
may be particularly noticeable for about 2 to 3 minutes after starting
operation (sound of coolant fl owing).
● During operation, a slight squeaking sound may be heard. This is the
result of minute expansion and contraction of the front cover due to
temperature changes.
Smells: ● Some smell may be emitted from the indoor unit.
This smell is the result
of room smells (furniture, tobacco, etc.) which have been taken into
the air conditioner
.
Mist or steam are emitted:
● During Cooling operation, a thin mist may be seen emitted from the
indoor unit. This results from the sudden Cooling of room air by the air
emitted from the air conditioner, resulting in condensation and misting.
CHECK
ONCE MORE
Doesn’t operate at all: ● Is the power plug disconnected from its outlet?
● Has there been a power failure?
● Has a fuse blown out, or a circuit breaker been tripped?
● Is the main power switch set to the OFF position?
● Is the timer operating?
Poor Cooling performance:
● Is the air fi lter dirty?
● Are the air conditioner’s intake grille or outlet port blocked?
● Did you adjust the room temperature settings (thermostat) correctly?
● Is there a window or door open?
● In the case of cooling operation, is a window allowing bright sunlight
to enter? (Close the curtains.)
● In the case of Cooling operation, are there heating apparatus or
computers inside the room, or are there too many people in the room?
If the problem persists after performing these checks, or if you notice burning smells, immediately stop operation, disconnect the
Power Supply Plug, and consult authorized service personnel.

OPERATION DETAILS
Temperature and Humidity Range
Permissible ranges of temperature and humidity are as follows:
Cooling
Operation
Outdoor temperature:
About 18°C to 4°C
Indoor humidity:
About 80% or less. If the unit is used for
long periods under conditions of high hu-
midity, water may condense on and drip
from the surface of the unit.
If the unit is used under higher temperature conditions than
those noted here, the automatic protection circuit may op-
erate, interrupting the operation. If the unit is used under
lower temperature conditions than those noted here, the
heat exchanger may freeze, causing water leakage or other
malfunction.
● Do not use the air conditioner for any purpose other than
room cooling.
