English

Do not install the air conditioner in the following locations: 
1.

Where there is a high concentration of mineral oil spray 
or vapour (e.g. a kitchen). 
Plastic parts will deteriorate, parts may fall off and water 
leakage could result. 

2.

Where corrosive gas, such as sulphurous acid gas, is 
produced. 
Corroding of copper pipes or soldered parts may result 
in refrigerant leakage. 

3.

Near machinery emitting electromagnetic radiation. 
Electromagnetic radiation may disturb the operation of the 
control system and result in a malfunction of the unit. 

4.

Where flammable gas may leak, where there is carbon 
fibre or ignitable dust suspensions in the air, or where vol-
atile flammables such as paint thinner or gasoline are han-
dled.
Operating the unit in such conditions may result in fire.

Do not touch the heat exchanger fins.
Improper handling may result in injury.

Be very careful about product transportation.
Some products use PP bands for packaging. Do not use any 
PP bands for a means of transportation. It is dangerous.

Safely dispose of the packing materials.
Packing materials, such as nails and other metal or wooden 
parts, may cause stabs or other injuries.
Tear apart and throw away plastic packaging bags so that 
children will not play with them. If children play with a plastic 
bag which was not torn apart, they face the risk of suffocation.

Do not turn off the power immediately after stopping operation.
Always wait at least 5 minutes before turning off the power.
Otherwise, water leakage and trouble may occur.

In a domestic environment this product may cause radio 
interference in which case the user may be required to take 
adequate measures.

Follow national standards for installation work.

2. BEFORE INSTALLATION

The accessories needed for installation must be retained in 
your custody until the installation work is completed. Do 
not discard them!

1. Decide upon a line of transport.
2. Leave the unit inside its packaging while moving, until 

reaching the installation site. Where unpacking is unavoid-
able, use a sling of soft material or protective plates 
together with a rope when lifting, to avoid damage or 
scratches to the unit.

When moving the unit at or after opening, hold the unit by 
the hanger brackets. Do not apply force to the refrigerant 
piping, drain piping or flange parts.
Be sure to check the type of R410A refrigerant to be used 
before installing the unit.
(Using an incorrect refrigerant will prevent normal opera-
tion of the unit.)

For the installation of an outdoor unit, refer to the installation 
manual attached to the outdoor unit.

2-1 PRECAUTIONS

Be sure to instruct customers how to properly operate the 
unit (operating different functions, and adjusting the temper-
ature ) by having them carry out operations themselves while 
looking at the operation manual.

Do not install in locations where the air contains high levels of 
salt such as that near the ocean and where voltage fluctuates 
greatly such as that in factories, or in vehicles or vessels.

2-2 ACCESSORIES

Check the following accessories are included with your unit.

2-3 OPTIONAL ACCESSORIES

This indoor unit requires one of the operation remote controls
