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 2.5 m above the oor 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.
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.
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.
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,
scaolding or any other means of elevation won’t be considered
in-warranty and charged to end user.

replaced by service agent or similarly qualied 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 qualied
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.

 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.
