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
 The unit should not be installed by the user. Ask the dealer or
authorized company to install the units.
 If the unit is installed improperly, water leakage, electric shock or fire
may result.
 Mount with the lowest moving parts at least 2.5m above the floor or
grade level. (If applicable)
 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.
 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.
 This appliance is not accessible to the general public. This appliance
should be installed according to the provided installation instruction.
 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.
 If any gas or impurities except R410A refrigerant come into the
refrigerant pipe, serious problem may occur and it may cause injury.
 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.
 Ventilate your room when refrigerant gas leaks during installation.
- Toxic gas may generate when refrigerant gas contacts with heat.

POWER SUPPLY LINE OR CIRCUIT BREAKER
 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.
 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.
 The air conditioner must be installed in accordance with national
wiring regulations and safety regulations wherever applicable.
 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.
 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.
 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.
Safety Precautions (Continued)

 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 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.
 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.

Selecting the Installation Location
Indoor Unit
 Select a convenient location that permits the air to reach every corner of the
area to be cooled.
 Pre-plan for easy and short routing of the refrigerant tubing and wiring to
the outdoor unit.
 There should be no flammable gas, alkaline, substances present in the air.
 Avoid location where obstacles preventing good air circulation are present.
 Noise prevention should be considered in determining the unit's location.
 The structure, where the unit is to be installed should be strong enough to
support the weight of the unit.
 Rigid wall without vibration.
 Where it is not exposed to direct sunshine.
 Where the air filter can be removed and cleaned easily.
Space Requirements for Indoor Unit
Observe the clearances and maximum lengths as seen in the picture below when
installing the air conditioner.
125 mm
or more
300 mm or more
125 mm

Wrap the refrigerant pipes and the drain
hose with the absorbent pad and vinyl
tape. Refer to page 15 for further details.
You can select the direction
of draining. (left or right)
The appearance of the unit may be different from the diagram depending on the model.

Fixing the Installation Plate
Before fixing the installation plate to the wall or window frame, you must
determine the position of the 65mm hole through which the cable, pipe and
hose pass to connect the indoor unit to the outdoor unit.
When facing the wall, the pipe and cable can be connected from the:
 Right
 Left
 Underside (right)
 Rear (right or left)
1
Determine the position of the pipe and drain hose hole as seen in the picture
and drill the hole with an inner diameter of 65mm so that it slants slightly
downwards.
2If you fix the indoor unit to a... Follow step(s)...
Wall 3.
Window frame 4 to 6.
3
Fix the installation plate to the wall giving attention to the weight of the
indoor unit.
 If you mount the plate to a concrete wall with anchor bolts, the anchor
bolts must not project more than 20mm.
4
Determine the positions of the wooden uprights to be attached to the
window frame.
5
Attach the wooden uprights to the window frame giving attention to the
weight of the indoor unit.
6
Attach the installation plate to the wooden uprights using tapping screws as
seen in the picture.

Purging the Unit
On delivery, the indoor unit is loaded with an inert Nitrogen gas.
All this gas must therefore be purged before connecting the assembly piping.
To purge the inert gas, proceed as follows.
1Unscrew the caps at the end of each pipe.
Result: All inert gas escapes from the indoor unit.
Note To prevent dirt or foreign objects from getting into the pipes
during installation, do NOT remove the caps completely until you are
ready to connect the piping.

Connection of refrigerant piping & Insulation
1Insert bot anchors, use existing ceiling supports or construct
a suitable support.
CAUTION
Ensure 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.
2Connect the “IN” refrigerant pipe to the outdoor unit.
3Connect the “OUT” refrigerant pipe to each indoor unit(A, B and C).
The liquid and gas pipes should not be crossed when piping connection.
4Insulate the connection piping. A joint part of pipe needs double
thickness of insulation.
