Precautions for safety
The manufacturer shall not assume any liability for the damage caused by not observing the description of this
manual.
WARNING
General
Before starting to install the air conditioner, read carefully through the Installation Manual, and follow its instructions
to install the air conditioner.
Only a qualified installer(*1) or qualified service person(*1) is allowed to install the air conditioner. If the air conditioner
is installed by an unqualified individual, a fire, electric shocks, injury, water leakage, noise and/or vibration may result.
Do not use any refrigerant different from the one specified for complement or replacement. Otherwise, abnormally
high pressure may be generated in the refrigeration cycle, which may result in a failure or explosion of the product or
an injury to your body.
When transporting the air conditioner, use a forklift and when moving the air conditioner by hand, move the unit with
4 people.
Before opening the intake grille of the indoor unit or service panel of the outdoor unit, set the circuit breaker to the
OFF position. Failure to set the circuit breaker to the OFF position may result in electric shocks through contact with
the interior parts. Only a qualified installer(*1) or qualified service person(*1) is allowed to remove the intake grille of
the indoor unit or service panel of the outdoor unit and do the work required.
Before carrying out the installation, maintenance, repair or removal work, be sure to set the circuit breaker to the OFF
position. Otherwise, electric shocks may result.
Place a “Work in progress” sign near the circuit breaker while the installation, maintenance, repair or removal work
is being carried out. There is a danger of electric shocks if the circuit breaker is set to ON by mistake.
Only a qualified installer(*1) or qualified service person(*1) is allowed to undertake work at heights using a stand of
50 cm or more.
Wear protective gloves and safety work clothing during installation, servicing and removal.
Do not touch the aluminum fin of the outdoor unit. You may injure yourself if you do so. If the fin must be touched for
some reason, first put on protective gloves and safety work clothing, and then proceed.
Do not climb onto or place objects on top of the outdoor unit. You may fall or the objects may fall off of the outdoor
unit and result in injury.
When working at heights, use a ladder which complies with the ISO 14122 standard, and follow the procedure in the
ladder’s instructions. Also wear a helmet for use in industry as protective gear to undertake the work.
When cleaning the filter or other parts of the outdoor unit, set the circuit breaker to OFF without fail, and place a “Work
in progress” sign near the circuit breaker before proceeding with the work.
When working at heights, put a sign in place so that no-one will approach the work location, before proceeding with
the work. Parts and other objects may fall from above, possibly injuring a person below.
The refrigerant used by this air conditioner is the R410A.
You shall ensure that the air conditioner is transported in stable condition.
Do not modify the products. Do not also disassemble or modify the parts. It may cause a fire, electric shock or injury.
Selection of installation location
If you install the unit in a small room, take appropriate measures to prevent the refrigerant from exceeding the limit
concentration even if it leaks. Consult the dealer from whom you purchased the air conditioner when you implement
the measures. Accumulation of highly concentrated refrigerant may cause an oxygen deficiency accident.
Do not install the air conditioner in a location that may be subject to a risk of expire to a combustible gas. If a
combustible gas leaks and becomes concentrated around the unit, a fire may occur.
When transporting the air conditioner, wear shoes with additional protective toe caps.
When transporting the air conditioner, do not take hold of the bands around the packing carton. You may injure
yourself if the bands should break.
Do not place any combustion appliance in a place where it is directly exposed to the wind of air conditioner, otherwise
it may cause imperfect combustion.
Installation
Install the air conditioner at enough strong places to withstand the weight of the unit. If the strength is not enough,
the unit may fall down resulting in injury.
Follow the instructions in the Installation Manual to install the air conditioner. Failure to follow these instructions may
cause the product to fall down or topple over or give rise to noise, vibration, water leakage, etc.
The designated bolts (M10) and nuts (M10) for securing the outdoor unit must be used when installing the unit.
Install the outdoor unit property in a location that is durable enough to support the weight of the outdoor unit.
Insufficient durability may cause the outdoor unit to fall, which may result in injury.
If refrigerant gas has leaked during the installation work, ventilate the room immediately. If the leaked refrigerant gas
comes in contact with fire, noxious gas may be generated.
