WARNING

Do not install, remove and reinstall the unit by yourself.

Improper installation will cause water leakage, electrical shock,

or fire. Please consult authorized dealer or specialist for the

installation work. Please note fault caused by improper

installation is not covered by warranty.

Safety precautions

WARNING

Do not install it yourself.

Install the unit securely in a place which

can bear the weight of the unit.

Use the specified wires to connect the

indoor and outdoor units securely and

attach the wires firmly to the terminal

board connecting sections so the stress

of the wires is not applied to the sections

Incorrect installation could cause injury due to fire,

electric shock, the unit falling or leakage of water.

Consult the dealer from whom you purchased the

unit or special installer

When installed in an insufficiently strong place,

the unit could fall causing injury.

Incorrect connection and fixing could cause a fire.

If the capacity of the power circuit is insufficient

or there is incomplete electrical work, it could

result in a fire or an electric shock.

The use of defective parts could cause an injury

due to a fire, electric shock, the unit falling, etc.

Incorrect installation could cause a personnel

injury due to fire, electric shock, the unit falling

or leakage of water.

If the electrical part covers of the indoor unit

and/or the service panel of the outdoor unit

are not attached securely, it could result in a

fire or electrical shock due to dust, water, etc.

Perform electrical work according to the

installation manual and be sure to use an

exclusive circuit.

Be sure to use the part provided or

specified parts for the installation work.

Perform the installation securely referring

to the installation instruction.

Check that the refrigerant gas does not

leak after installation is completed.

Attach the electrical part cover to the indoor unit and

the service panel to the outdoor unit securely.

Be sure to read the following WARNING before installing the air

conditioner.

Be sure to observe the cautions specified here as they include

important items related to safety.

After reading this instructions, be sure to keep it together with the

owners manual in a handy place for future reference.

SAFETY PRECAUTIONS

The following should be always observed for safety:

CAUTIONS

Do not install the unit in a place where

a flammable gas leaks.

If gas leaks and accumulates in the area

surrounding the unit, it could cause a

explosion.

If there is a defect in the drainage/piping work,

water could leak from the unit and household

goods could get wet and be damaged.

Perform the drainage/piping work according to the

installation instruction.

Installation Instruction

INSTALLATION OF INDOOR AND OUTDOOR UNITS

Read completely, then follow step 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.

A minimum pipe run of 3 metres is required to minimise vibration & excessive noise.

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.

Note:

Fit the Installation Plate

1. Fit the installation plate horizontally

on structural parts of the wall with

spaces around the installation plate.

2. If the wall is made of brick, concrete or

the like, drill eight (8) 5mm diameter holes

in the wall. Insert Clip anchor for appropriate

mounting screws.

3. Fit the installation plate on the wall with eight

(8) type “A” screws.

Correct orientation

of Installation Plate

Fit the Installation Plate and drill holes in the wall according to the wall structure

and corresponding mounting points on the installation plate.

(Dimensions are in “mm” unless otherwise stated)

1. Determine hole positions according to

the diagram detailed in Fig.5. Drill

one (1) hole ( 65mm) slanting slightly

to outdoor side.

2. Always use wall hole conduit when

drilling metal grid, metal plate or the like.

Installation Instruction

1. For the left-hand and right-hand piping, remove the pipe cover from the side panel.

Explain to clients that the pipe cover must be kept as it may be used when relocate the

air conditioner to any other place.

2. For the rear-right-hand and rear-left-hand piping, install the piping as shown. Bend the

connective pipe to be laid at 43mm height or less from the wall.

3. Fix the end of the connective pipe. (Refer to Tightening Connection in REFRIGERANT

PIPING CONNECTION)

Connective pipe

Indoor unit outline

Connective pipe

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.

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.

B: Burr removal

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.

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
