CAUTION

While following the instructions in this installation man-
ual, insulate piping in order to prevent condensation.

Improper piping insulation may result in water leakage and 
property damage.

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 suffoca-
tion. 

Do not turn off the power immediately after stopping 
operation. 

Always wait at least five minutes before turning off the power. 
Otherwise, water leakage and trouble may occur.

NOTE

Install the indoor and outdoor units, power supply wir-
ing and connecting wires at least 3.5ft. away from televi-
sions or radios in order to prevent image interference or 
noise.

(Depending on the radio waves, a distance of 3.5ft. may not 
be sufficient enough to eliminate the noise.)

Remote controller (wireless kit) transmitting distance 
can result shorter than expected in rooms with elec-
tronic fluorescent lamps. (inverter or rapid start types)

Install the indoor unit as far away from fluorescent lamps as 
possible.

This unit is a class A product.

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

Dismantling of the unit, treatment of the refrigerant, oil 
and eventual other parts, should be done in accordance 
with the relevant local and national regulations. 

2. BEFORE INSTALLATION

When moving the unit while removing it from the packing 
case, be sure to lift it without exerting any pressure on 
other parts, especially, the refrigerant piping, drain pip-
ing, and other resin parts.

• Be sure to check the type of R410A refrigerant to be used 

before installing the unit. (Using an incorrect refrigerant will 
prevent normal operation of the unit.)

• The accessories needed for installation must be retained in 

your custody until the installation work is completed. Do not 
discard them!

• Decide upon a line of transport.
• Leave the unit inside its packaging while moving, until reach-

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

• For the installation of an outdoor unit, refer to the installation 

manual attached to the outdoor unit.

• Do not install or operate the unit in rooms mentioned below.

Laden with mineral oil, or filled with oil vapor or spray 
like in kitchens. (Plastic parts may deteriorate which 
could eventually cause the unit to fall out of place, or 
could lead to leaks.)

Where corrosive gas like sulfurous gas exists. (Cop-
per tubing and brazed spots may corrode which could 
eventually lead to refrigerant leaks.)

Where exposed to flammable gases and where vola-
tile liquids like thinner or gasoline is used. (Gas in the 
vicinity of the unit could ignite.)

Where machines can generate electromagnetic 
waves. (Control system may malfunction.)

Where the air contains high levels of salt such as that 
near the ocean and where voltage fluctuates greatly 
such as that in factories. 
Also in vehicles or vessels.

• This unit, both indoor and outdoor, is suitable for installation in a 

commercial and light industrial environment.
If installed as a household appliance it could cause electro-
magnetic interference.

NOTE

• Be sure to read this manual before installing the indoor unit.
• Entrust installation to the place of purchase or an authorized 

serviceman. Improper installation could lead to leaks and, in 
worse cases, electric shock of fire.

• Use only parts provided with the unit or parts satisfying 

required specifications. Unspecified parts could cause the 
unit to fall out of place, or could lead to leaks and, in worse 
cases, electric shock or fire.
