WARNING
Read the follow SAFETY PRECAUTIONS carefully before installation.
Electrical work must be installed by a licensed electrician. Be sure to use the correct rating and
main circuit for the model to be installed.
Incorrect installation due to ignoring of the instruction will cause harm or damage, and the seri-
ousness is classified by the following indications.
This symbol indicates the possibility of death or serious injury.
The items to be followed are classified by the symbols:
Symbol will background white denotes item that is PROHIBITED from doing.
!
CAUTION
This symbol indicates the possibility of injury or damage to property.
WARNING
!
1) Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water
leakage, electrical shock fire.
2) Install according to this installation instructions strictly. If installation is defective, it will cause water
leakage, electrical shock fire.
3) Use the attached accessories parts and specified parts for installation. otherwise, it will cause the set to fall,
water leakage, electrical shock fire.
4) Install at a strong and firm location which is able to withstand the set s weight. If the strength is not enough
or installation is not properly done, the set will drop and cause injury.
,
5) For electrical work, follow the local national wiring standard, regulation and this installation instructions. An
independent circuit and single outlet must be used. If electrical circuit capacity is not enough or defect found
in electrical work, it will cause electrical shock fire.
6) Use the specified cable and connect tightly and clamp the cable so that no external force will be acted on
the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the connection.
7) Wiring routing must be properly arranged so that control board cover is fixed properly. If control board cover
is not fixed perfectly, it will cause heat-up at connection point of terminal, fire or electrical shock.
8) When carrying out piping connection, take care not to let air substances other than the specified
refrigerant go into refrigeration cycle. Otherwise, it will cause lower capacity, abnormal high pressure
in the refrigeration cycle, explosion and injury.
9) Do not modify the length of the power supply cord or use of extension cord, and do not share the
single outlet with other electrical appliances. Otherwise, it will cause fire or electrical shock.
!
CAUTION
1) This equipment must be earthed and installed with earth leakage current breaker. It may cause electrical
shock if grounding is not perfect.
2) Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and
accumulates at surrounding of the unit, it may cause fire.
3) Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water
may enter the room and damage the furniture.
SAFETY PRECAUTIONS

Selecting installation place
Read completely, then followstep by step.
Indoor unit
Do not expose the indoor unit to heat or steam.
Select a place where there are no obstacles
in front or around the unit.
Make sure that condensation drainage can
be conveniently routed away.
Do not install near a doorway.
Ensure that the space on the left and right
of the unit is more than 12cm.
Use a stud finder to locate studs to prevent unnecessary damage to the wall.
The indoor unit should be installed on the wall at a height of 2.3 metres or more from the floor.
The indoor unit should be installed allowing a minimum clearance of 15cm from the ceiling.
Any variations in pipe length will/may require adjustment to refrigerant charge.
Outdoor unit
If an awning is built over the outdoor unit to
prevent direct sunlight or rain exposure,
make sure that heat radiation from the
condenser is not restricted.
Ensure that the clearance around the back
of the unit is more than 30cm and left side is
more than 30cm. The front of the unit should
have more than 200cm of clearance and the
connection side (right side) should have more
than 60cm of clearance.
Do not place animals and plants in the path of the air inlet or outlet.
Take the air conditioner weight into account and select a place where noise and vibration
will not be an issue.
Select a place so that the warm air and noise from the air conditioner do not disturb neighbors.
If the outdoor unit is installed on a roof structure, be sure to level the unit.
Ensure the roof structure and anchoring method are adequate for the unit location.
Consult local codes regarding rooftop mounting.
If the outdoor unit is installed on roof structures or external walls, this may result in excessive
noise and vibration, and may also be classed as a non serviceable installation.

1. Pass the piping through the hole in the wall.
2. Put the upper claw at the back of the indoor unit on
the upper hook of the installation plate, move the
indoor unit from side to side to see that it is securely
hooked.
3. Piping can easily be made by lifting the indoor unit
with a cushioning material between the indoor unit
and the wall. Get it out after finish piping.
4. Push the lower part of the indoor unit up on the wall,
Then move the indoor unit from side to side, up and
down to check if it is hooked securely.

5. Piping and wrapping
Bundle the tubing, connecting cable, and
drain hose with tape securely,
evenly as shown in Fig.10.
Because the condensed water from rear
of the indoor unit is gathered in ponding
box and is piped out of room. Do not put
anything else in the box.

Connect the indoor unit first, then the outdoor unit.
Do not allow the piping to let out from the back of the indoor unit.
Be careful not to let the drain hose slack.
Heat insulated both of the auxiliary piping.
Be sure that the drain hose is located at the lowest side of the bundle. Locating
at the upper side can cause drain pan to overflow inside the unit.
Never intercross nor intertwist the power wire with any other wiring.
Run the drain hose sloped downward to drain out the condensed water smoothly.
CAUTION
Install the outdoor unit on a rigid base to prevent increasing noise level and vibration.
Determine the air outlet direction where the discharged air is not blocked.
In the case that the installation place is exposed to strong wind such as a seaside,
make sure the fan operating properly by putting the unit lengthwise along the wall
or using a dust or shield plates.
Specially in windy area, install the unit to prevent the admission of wind.
If need suspending installation, the installation bracket should accord with technique
requirement in the installation bracket diagram. The installation wall should be solid
brick, concrete or the same intensity construction,
or actions to reinforce, damping supporting should
be taken. The connection between bracket and
wall, bracket and the air conditioner should be
firm, stable and reliable.
Be sure there is no obstacle which block
radiating air.

Settlement of outdoor unit
Anchor the outdoor unit with
a bolt and nut 10 or 8 tightly
and horizontally on a concrete
or rigid mount.
Fit the seal into the drain elbow, then insert
the drain joint into the base pan hole of
outdoor unit, rotate 90 to securely assemble
them. Connecting the drain joint with an
extension drain hose (Locally purchased),

Burr
Main cause for refrigerant leakage
is due to defect in the flaring work.
Carry out correct flaring work
using the following procedure:
A: Cut the pipes and the cable.
1. Use the piping kit accessory or pipes
purchased locally.
2. Measure the distance between the indoor and the outdoor unit.
3. Cut the pipes a little longer than the 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. Put the end of the copper tube/pipe in a
downward direction as you remove burrs in
order to avoid dropping burrs into the tubing.

Electric safety regulations for the initial Installation
1. If there is serious safety problem about the power supply, the technicians should refuse
to install the air conditioner and explain to the client until the problem is solved.
2. Power voltage should be in the range of 90%~110%of rated voltage.
3. The creepage protector and main power switch with a 1.5 times capacity of Max. Current
of the unit should be installed in power circuit.
4. Ensure the air conditioner is grounded well.
7. An individual branch circuit and single receptacle used only for this air conditioner must be
available. See the following table for suggested wire sizes and fuse specifications:
5. According to the attached Electrical Connection Diagram located on the panel of the outdoor
unit to connect the wire.
6. All wiring must comply with local and national electrical codes and be installed
by qualified and skilled electricians.
