• Do not cool excessively indoors. This may be harmful for your health and may consume more
electricity.
• Block sunlight with blinds or curtains while you are operating the air conditioner.
• Keep doors or windows closed tightly while you are operating the air conditioner.
• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
• Speed up the fan to cool or warm indoor air quickly, in a short period of time.
• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air condi-
tioner is used for many hours.
• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the
air flow or weaken the cooling / dehumidifying functions.

Here are some tips that will help you minimize the power consumption when you use the air
conditioner. You can use your air conditioner more efficiently by referring to the instructions
below:
TIPS FOR SAVING ENERGY
- Otherwise, the expansion valve or capillary tube may become blocked with contaminants.
• For R410A model, use piping, flare nut and tools which is specified for R410A refrigerant.
- Using of (R22) piping, flare nut and tools may cause abnormally high pressure in the refrigerant
cycle (piping), and possibly result in explosion and injury.
• It is desirable that the amount of residual oil less than 40 mg/10 m.
• Do not turn on the breaker or power under condition that front panel, cabinet, top cover, control box
cover are removed or opened.
- Otherwise, it may cause fire, electric shock, explosion or death.
Operation
• Do not share the outlet with other appliances.
- It will cause an electric shock or a fire due to heat generation.
• Do not use the damaged power cord.
- Otherwise, it may cause a fire or electrical shock.
• Do not modify or extend the power cord randomly.
- Otherwise, it may cause a fire or electrical shock.
• Take care so that the power cord may not be pulled during operation.
- Otherwise, it may cause a fire or electrical shock.
• Unplug the unit if strange sounds, smell, or smoke comes from it.
- Otherwise, it may cause electrical shock or a fire.
• Keep the flames away.
- Otherwise, it may cause a fire.
• Take the power plug out if necessary, holding the head of the plug and do not touch it with wet
hands.
- Otherwise, it may cause a fire or electrical shock.
• Do not use the power cord near the heating tools.
- Otherwise, it may cause a fire and electrical shock.
• Do not open the suction inlet of the indoor/outdoor unit during operation.
- Otherwise, it may electrical shock and failure.
• Do not allow water to run into electrical parts.
- Otherwise, it may cause the failure of machine or electrical shock.
• Hold the plug by the head when taking it out.
- It may cause electric shock and damage.
• Never touch the metal parts of the unit when removing the filter.
- They are sharp and may cause injury.
ENGLISH

Fixing Installation Plate
The wall you select should be strong and solid
enough to prevent vibration.
1
Before installation, confirm the chassis name
on the box of indoor unit.
2
Mount the installation plate on the wall
with type "A" screws. If mounting the unit
on a concrete wall, use anchor bolts.
- Mount the installation plate horizontally
by aligning the centerline using Horizontal
meter .
3
Measure the wall and mark the centerline.
It is also important to use caution concern-
ing the location of the installation plate.
Routing of the wiring to power outlets is
through the walls typically. Drilling the hole
through the wall for piping connections
must be done safely.

Flaring Work
Main cause for gas leakage is due to defect of
flaring work. Carry out correct flaring work in
the following procedure.
Cut the pipes and the cable
1
Use the piping kit accessory or the pipes
purchased locally.
2
Measure the distance between the indoor
and the outdoor unit.
3
Cut the pipes a little longer than measured
distance.
4
Cut the cable 1.5m longer than the pipe
length.

1. Completely remove all burrs from the cut
cross section of pipe/tube.
2. While removing burrs put the end of the
copper tube/pipe in a downward direction
while removing burrs location is also
changed in order to avoid dropping burrs
into the tubing.
Putting nut on
- Remove flare nuts attached to indoor and
outdoor unit, then put them on pipe/tube
having completed burr removal.
(not possible to put them on after finishing
flare work)
Flaring work
1
Firmly hold copper pipe in a bar with the di-
mension shown in below table table
below.
2
Carry out flaring work with the flaring tool.
Check
1
Compare the flared work with the figure
by.
2
If a flared section is defective, cut it off
and do flaring work again.

Installation of Indoor Unit
1
Hook the indoor unit onto the upper por-
tion of the installation plate.( engage the
three hooks at the top of the indoor unit
with the upper edge of the installation
plate) Ensure that the hooks are properly
seated on the installation plate by moving
it left and right
2
Unlock the tubing holder from the chassis
and mount between the chassis and instal-
lation plate in order to separate the bottom
side of the indoor unit from the wall.
* The feature can be changed according to a
type of model.
Piping
1
Insert the connecting cable through the
bottom side of indoor unit and connect the
cable (You can see detail contents in 'Con-
necting the cables' section)
<Left side piping>
<Right side piping>
2
Secure the cable onto the control board
with the cable retainer.
3
Tape the tubing pipe, drain hose and the
connection cable. Be sure that the drain
hose is located at the lowest side of the
bundle. Locating at the upper side can
cause overflow from the drain pan through
the inside of the unit.

CAUTION
According to the confirmation of the
above conditions, prepare the wiring as
follows.
1
Never fail to have an individual power
circuit specifically for the air condi-
tioner. As for the method of wiring, be
guided by the circuit diagram posted
on the inside of control cover.
2
The screw which fasten the wiring in
the casing of electrical fittings are li-
able to come loose from vibrations to
which the unit is subjected during the
course of transportation. Check them
and make sure that they are all tightly
fastened. (If they are loose, it could
cause burn-out of the wires.)
3
Specification of power source.
4
Confirm that electrical capacity is suffi-
cient.
5
See that the starting voltage is main-
tained at more than 90 percent of the
rated voltage marked on the name
plate.
6
Confirm that the cable thickness is as
specified in the power source specifi-
cation.
(Particularly note the relation between
cable length and thickness.
7
Always install an earth leakage circuit
breaker in a wet or moist area.
8
The following would be caused by volt-
age drop.
- Vibration of a magnetic switch, which
will damage the contact point, fuse
breaking, disturbance of the normal
function of the overload.
9
The means for disconnection from a
power supply shall be incorporated in
the fixed wiring and have an air gap
contact separation of at least 3mm in
each active(phase) conductors.
!
Checking the Drainage
To check the drainage.
1
Pour a glass of water on the evaporator.
2
Ensure the water flows through the drain
hose of the indoor unit without any leak-
age and goes out the drain exit.
