Safety Precautions
The following safety precautions must be taken when using your air conditioner.
WARNING
• Risk of electric shock can cause injury or death. • Disconnect all remote electric power
supplies before servicing, installing or cleaning.
• Installation must be done by the manufacturer or service agent or a similar qualified
person in order to avoid a hazard.
Installing the unit
f The unit should not be installed by the user. Ask the dealer or authorized company to install the units.
f If the unit is installed improperly, water leakage, electric shock or fire may result.
f Mount with the lowest moving parts at least 2.5m (8.2 ft) above the floor or grade level. (If applicable)
f The manufacturer does not assume responsibility for accidents or injury caused by an incorrectly installed air conditioner.
If you are unsure about installation, contact an installation specialist.
f When installing the built-in type air conditioner, keep all electrical cables such as the power cable and the connection
cord in pipe, ducts, cable channels e.t.c to protect them against liquids, outside impacts and so on. The air conditioner
should be used only for the applications for which it has been designed: the indoor unit is not suitable to be installed in
areas used for laundry.
f This appliance is not accessible to the general public. This appliance should be installed according to the provided
installation instruction.
f When installing the air conditioner in a small room, the measure not to exceed the dangerous density is needed.
- When refrigerant leaks and exceeds the dangerous density, suffocation may occur.
f If any gas or impurities except R410A refrigerant come into the refrigerant pipe, serious problem may occur and it may
cause injury.
f Use only rated accessories and install the air conditioner with rated equipments.
- If you dont’t use the rated accessories, the air conditioner may drop from its place, water may leak or electric shock or
fire may occur.
f Ventilate your room when refrigerant gas leaks during installation.
- Toxic gas may generate when refrigerant gas contacts with heat.
f Our units must be installed in compliance with the spaces indicated in the installation manual to ensure either
accessibility from both sides or ability to perform routine maintenance and repairs. The units’components must be
accessible and that can be disassembled in conditions of complete safety either for people or things.
For this reason, where it is not observed as indicated into the Installation Manual, the cost necessary to reach and repair
the unit (in safety, as required by current regulations in force) with slings, trucks, scaffolding or any other means of
elevation won’t be considered in-warranty and charged to end user.

Safety precautions
Power supply line or circuit breaker
f If the power cable of this air conditioner is damaged, it must be replaced by service agent or similarly qualified persons in
order to avoid a hazard.
f The unit must be plugged into an independent circuit if applicable or connect the power cable to the auxiliary circuit
breaker. An all pole disconnection from the power supply must be incorporated in the fixed wiring with a contact
opening of >3mm (0.12 inch).
f The air conditioner must be installed in accordance with national wiring regulations and safety regulations wherever
applicable.
f The electric work must be done by service agent or similarly qualified persons according to national wiring regulations
and use only rated cable.
- If the capacity of the power cable is insufficient or electric work is not properly completed, electric shock or fire may
occur.
f Install the cables with supplied cables firmly. Fix them securely so that external force is not exerted to the terminal board.
- If the connection or fixing is incomplete, heat generation, electric shock or fire may occur.
f Connect the power cable between the indoor and outdoor unit properly so that the electrical component box cover is
not get loosen and attach the cover securely.
- If the the cover is attached incompletely, heat generation, electric shock or fire of the terminal board may occur.
• Make sure that you earth the cables.
- Do not connect the earth wire to the gas pipe, water pipe, lighting rod or telephone wire. If earthing is not
complete, electric shock or fire may occur.
• Install the circuit breaker.
- If the circuit breaker is not installed, electric shock or fire may occur.
• Make sure that the condensed water dripping from the drain hose runs out properly and safely.
• Install the power cable and communication cable of the indoor and outdoor unit at least 1m (3.28 ft) away from
the electric appliance.
• Install the indoor unit away from lighting apparatus using the ballast.
- If you use the wireless remote control, reception error may occur due to the ballast of the lighting apparatus.
• Do not install the air conditioner in following places.
- Place where there is mineral oil or arsenic acid. Resin parts flame and the accessories may drop or water may
leak. The capacity of the heat exchanger may reduce or the air conditioner may be out of order.
- The place where corrosive gas such as sulfurous acid gas generates from the vent pipe or air outlet. The copper
pipe or connection pipe may corrode and refrigerant may leak.
- The place where there is a machine that generates electromagnetic waves. The air conditioner may not
operate normally due to control system.
- The place where there is a danger of existing combustible gas, carbon fiber or flammable dust.The place
where thinner or gasoline is handled. Gas may leak and it may cause fire.

Indoor Unit
f There must be no obstacles near the air inlet and outlet.
f Install the indoor unit on a ceiling that can support its weight.
f Maintain sufficient clearance around the indoor unit.
f Make sure that the water dripping from the drain hose runs away correctly and safely.
f The indoor unit must be installed in this way, that they are out of public access. (Not touchable by the users)
f After connecting a chamber, insulate the connection part between the indoor unit and the chamber with t10mm(3/8") or
thicker insulation. Otherwise, there can be air leak or dew from the connection part.
f Rigid wall without vibration.
f Where it is not exposed to direct sunshine.
f Where the air filter can be removed and cleaned easily.
Space requirements for installation & service
Unit Width(W)
“A”=W+100mm(3.94 inch)
“B”=500mm(19.69 inch)
Unit Depth(D)+50mm (1.97 inch)

20mm(0.79 inch) or more
f You must have 20mm(0.79 inch) or more space between the ceiling and the bottom of indoor unit. Otherwise, the noise
from the vibration of indoor unit may bother the user. When the ceiling is under construction, the hole for check-up must
be made to take service, clean and repair the unit.
f It is possible to install the unit at an height of between 2.2(7.22 ft) ~ 2.5m(8.20 ft) from the ground, if the unit has a duct
with a well defined lenght[300mm(0.98 ft) or more], to avoid fan motor blower contact.

Indoor Unit Installation
It is recommended to install theY-joint before installing the indoor unit.
1. Place the pattern sheet on the ceiling at the spot where you want to install
the indoor unit.
Concrete
Suspension bolt(Φ9.52(3/8") or M10)
Hole in anchor
Hole in plug
Insert
Ceiling support
Rubber
Drain hose port

• Since the diagram is made of paper, it may shrink or stretch slightly
due to temperature or humidity. For this reason, before drilling the
holes maintain the correct dimensions between the markings.
NOTE
2. Insert bolt anchors, use existing ceiling supports or construct a suitable
support as shown in figure.
3. Install the suspension bolts depending on the ceiling type.
• Ensure that the ceiling is strong enough to support the weight of
the indoor unit. Before hanging the unit, test the strength of each
attached suspension bolt.
• If the length of suspension bolt is more than 1.5m(4.92ft), it is
required to prevent vibration.
• If this is not possible, create an opening on the false ceiling in order
to be able to use it to perform the required operations on the indoor
unit.
CAUTION
4. Screw eight nuts to the suspension bolts making space for hanging the
indoor unit.
• You must install the suspension bolts more than four when
installing the indoor unit.
CAUTION
5. Hang the indoor unit to the suspension bolts between two nuts.
• Piping must be laid and connected inside the ceiling when
suspending the unit. If the ceiling is already constructed, lay the
piping into position for connection to the unit before placing the
unit inside the ceiling.
NOTE
6. Screw the nuts to suspend the unit.
7. Adjust level of the unit by using measurement plate for all 4 sides.
• For proper drainage of condensate, give a 1° slant to the left or right
side of the unit which will be connected with the drain hose, as
shown in the figure. Make a tilt when you wish to install the drain
pump, too.
