CAUTION!
This mark indicates procedures which, if improperly performed,
might possibly result in personal harm to the user, or damage to
property.
Read carefully all security information before use or install the air conditioner.
Do not attempt to install the air conditioner or a part of the air conditioner by yourself.
This unit must be installed by qualified personnel with a capacity certificate for handling
refrigerant fluids. Refer to regulation and laws in use on installation place.
Th
e installation must be carried out in compliance with regulations in force
in the place
of installation and the installation instructions of the manufacturer.
This unit is part of a set constituting an air conditioner. It must not be installed alone or
with non-authorized by the manufacturer.
Always use a separate power supply line protected by a circuit breaker operating on all
wires with a distance between contact of 3mm for this unit.
The unit must be correctly grounded and the supply line must be equipped with a
differential breaker in order to protect the persons.
The units are not explosion proof and therefore should not be installed in explosive

the unit.
2. ABOUT THE UNIT
2.1. Precautions for using the R410A refrigerant
WARNING
• Do notintroduceanysubstance other than the prescribed refrigerant into the
refrigeration cycle.
If air enters the refrigeration cycle, the pressure in the refrigeration cycle will become
abnormally high and cause the piping to rupture.
• Ifthereisarefrigerantleakage,makesurethatitdoesnotexceedtheconcentration
limit.
If a refrigerant leakage exceeds the concentration limit, it can lead to accidents such
as oxygen starvation.
• Do nottouch refrigerant thathas leaked fromthe refrigerant pipe connections or
other area. Touching the refrigerant directly can cause frostbite.
• If a refrigerant leakage occurs during operation, immediately vacate the premises
and thoroughly ventilate the area.
 Iftherefrigerantcomesincontactwithaame,itproducesatoxicgas.
2.2. Special tool for R410A
WARNING
• To install a unit that uses the R410Arefrigerant, use dedicated toolsand piping
materialsthathavebeenmanufacturedspecicallyforR410Ause.
 BecausethepressureoftheR410Arefrigerantisapproximately1.6timeshigherthan
the R22, failure to use dedicated piping material or improper installation can cause
rupture or injury.
Furthermore, it can cause serious accidents such as water leakage, electric shock, or
re.

• While brazing the pipes, be sure to purge with dry nitrogen gas.
4.1. Selecting the pipe material
CAUTION
• Do not use existing pipes.
• Use pipes that have clean external and internal sides without any contamination
which may cause trouble during use, such as sulfur, oxide, dust, cutting waste, oil, or
water.
• It is necessary to use seamless copper pipes.
Material:Phosphordeoxidizedseamlesscopperpipes
Itisdesirablethattheamountofresidualoilislessthan40mg/10m.
• Do not use copper pipes that have a collapsed, deformed, or discolored portion
(especiallyontheinteriorsurface).Otherwise,theexpansionvalveorcapillarytube
may become blocked with contaminants.
• Improperpipeselectionwilldegradeperformance.AsanairconditionerusingR410A
