• Remove the control box cover and insert the cable into the main unit 

through the cable holder located on the side.

• Check the colors of the wires on the terminal board, and secure 

them with screws.

• Secure the outer sheath of the connecting cable with the cord clamp. 
• Reattach the control box cover in its original position.

• Connect the indoor/outdoor connecting cable using the 

prescribed cable, and secure it firmly so that external force from 
the cable is not transmitted to the terminal connectors.

• Lift up the decorative grille from directly below to match it with the main 

unit, and tentatively secure it in place.

• Open the intake grille and the screw caps, and secure the decorative 

grille using the lock screws (4).

• When finishing the ceiling after the air conditioner has been installed, use the pattern       
    8  to indicate the ceiling opening dimensions as shown below. (The protection sheet 

of the pattern is used to prevent the air conditioner discharge vent from becoming 
dirty, so wrap it around the discharge vent as shown in the illustration.)

• Connecting cable between indoor unit and outdoor unit shall be 

approved polychloroprene sheathed 4 

× 1.5 mm

 flexible cord, type 

designation 245 IEC 57(H05RN-F) or heavier cord. 

   • Ensure the color of wires of outdoor unit and the terminal Nos. 

are the same to the indoor’s  respectively.

   • Earth lead wire shall be longer than the other lead wires as 

shown in the figure for the electrical safety in case of the slipping 
out of the cord from the anchorage.

The below operations will be performed by pressing the “AUTO” switch.

1. AUTO OPERATION MODE

1.

The Auto operation will be activated 

immediately once the “AUTO” switch is pressed.

2. TEST RUN OPERATION (FOR PUMP 

DOWN/SERVICING PURPOSE)

     The Test Run operation will be activated if 

the “AUTO” switch is pressed continuously for 

more than 5 sec. to below 8 sec..

1.

A short beep sound will occur at the fifth sec., 

in order to identify the starting of Test Run 

operation.

• When installing two air conditioners in one room, each air conditioner can be 

synchronized to the remote control.
In order to operate separately, open the rear cover of one of the remote control and set 
to “B”.

Setting the air conditioner unit to “B”

1. Press the “AUTO” switch for about 11 to 15 seconds.  When you hear three short beeps,  

release the switch.

1. 

Note: you will hear one short beep in about 5 seconds, and then two short beeps in about 

8 seconds.

2. Press again the  “AUTO”  switch within 60 seconds.  Every press the “AUTO” switch, you 

will hear a short beep.  When you hear eventually a long beep, stop pressing the

 “AUTO” switch , which achieves “B” setting.

1. 

If you stop pressing the “AUTO” switch midway at the short beep, this will achieve 

“A” setting.

3. After 60 seconds or longer of the above setting, use the “B” set remote control to confirm 

successful operation.

Set “B” on the remote control.

This can be achieved by cutting 

the jumper wire of the remote 

control with a cutter.

Required tools for Installation Works

•   Read the following “SAFETY PRECAUTIONS” carefully before installation.
•   Electrical work must be installed by a licensed electrician. Be sure to use the correct rating of the power plug and main 

circuit for the model to be installed.

•   The caution items stated here must be followed because these important contents are related to safety. The meaning of 

each indication used is as below. Incorrect installation due to ignoring of the instruction will cause harm or damage, and the 
seriousness is classified by the following indications.

•   Carry out test running to confirm that no abnormality occurs after the installation. Then, explain to user the operation, 

care and maintenance as stated in instructions. Please remind the customer to keep the operating instructions for future 
reference.

WARNING

This indication shows the possibility of causing death or serious injury.

CAUTION

This indication shows the possibility of causing injury or damage to properties only.

Symbol with background white denotes item that is PROHIBITED from doing.

1)

Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water leakage, 

electrical shock or fire.

2)

Install according to this installation instruction strictly. If installation is defective, it will cause water leakage, electrical 

shock or fire.

3)

Use the attached accessories parts and specified parts for installation. Otherwise, it will cause the set to fall, water leakage, 

fire or electrical shock.

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.

1)

This equipment must be earthed. It may cause electrical shock if grounding is not perfect.

5)

For electrical work, follow the local national wiring standard, regulation and this installation instruction. 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 or 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.

7)

Wire 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.

6)

Use the specified cable (1.5 mm

2

) and connect tightly for indoor/outdoor connection. Connect tightly and clamp the cable 

so that no

 externa

l force will be acted on the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the 

connection.

8)

When carrying out piping connection, take care not to let air substances other than the specified 

refrigerant go into refrigeration cycle.

8)

Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration cycle, explosion and 

injury.

9)

When connecting the piping, do not allow air or any substances other than the specified refrigerant 

(R410A) to enter the refrigeration cycle. Otherwise, this may lower the capacity, cause abnormally high 
pressure in the refrigeration cycle, and possibly result in explosion and injury.

10) Do not modify the length of the power supply cord or use of the extension cord, and do not share the 

single outlet with other electrical appliances. Otherwise, it will cause fire or electrical shock.

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.  

2)

Do not release refrigerant.

3)

Do not release refrigerant during piping work for installation, reinstallation and during repairing a refrigeration parts. Take 

care of the liquid refrigerant, it  may cause frostbite.

3)

Installation work.

4)

It may need two people to carry out the installation work.

4)

Do not install this appliance in a laundry room or other location where water may drip from the ceiling, etc.

1)

Selection of the installation location.

1)

Select a installation location which is rigid and strong enough to support or hold the unit, and select a location for easy 

maintenance.

The items to be followed are classified by the symbols:

Take into consideration the following contents when creating the blueprint.

The location should be strong enough to support the main unit 
without vibration.
There should not be any heat or steam sources nearby.
Drainage should be easy. Avoid locating the drain port close to 
ditches (domestic wastewater).
Avoid locations above entrances and exits.
Do not block the intake and discharge.
Select the location so that the cool and warm air spreads 
throughout the entire room.
Locate the indoor unit at least 1 m or more away from a TV, radio, 
wireless equipment, antenna cables and fluorescent lights, and 2 
m or more away from a telephone.

Note that if the air conditioning unit is installed near an 
electronically lit fluorescent light (inverter, rapid start type, etc.), 
it may not receive the remote control signals.

Signals may not be transmitted and received correctly when 
the remote control is operated while in the holder. Take the 
remote control in your hand to operate the unit.
Mount the holder in a location that is not subject to the 
effects of heat (direct sunlight and stoves, etc.).

1. Insert the piping sleeve to the hole.
2. Fix the bushing to the sleeve.
3. Cut the sleeve until it extrudes 

about 15 mm from the wall.

4. Finish by sealing the sleeve with 

putty or caulking compound at the 
final stage. 

• Prepare the piping set shown in the table 

below or equivalent products for the 
refrigerant piping.
