2. ABOUT THE UNIT
2.1. Precautions for using the R410A refrigerant
1
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 fl ame, it produces a toxic gas.
2.2. Special tool for R410A
To install a unit that uses the R410A refrigerant, use dedicated tools and piping
materials that have been manufactured specifi 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
fi re.

3.1. Selecting an installation location
WARNING
Select installation locations that can properly support the weight of the indoor. Install
the units securely so that they do not topple or fall.
CAUTION
Do not install the unit in the following areas:
• Area with high salt content, such as at the seaside.
It will deteriorate metal parts, causing the parts to fail or the unit to leak water.
• Area fi lled with mineral oil or containing a large amount of splashed oil or steam,
such as a kitchen.
It will deteriorate plastic parts, causing the parts to fail or the unit to leak water.
• Area that generates substances that adversely affect the equipment, such as sulfuric
gas, chlorine gas, acid, or alkali.
It will cause the copper pipes and brazed joints to corrode, which can cause
refrigerant leakage.
• Area that can cause combustible gas to leak, contains suspended carbon fi bers or
fl ammable dust, or volatile infl ammables such as paint thinner or gasoline.
If gas leaks and settles around the unit, it can cause a fi re.
• Area where animals may urinate on the unit or ammonia may be generated.
Do not use the unit for special purposes, such as storing food, raising animals, growing
plants, or preserving precision devices or art objects.
It can degrade the quality of the preserved or stored objects.
Do not install where there is the danger of combustible gas leakage.
Do not install the unit near a source of heat, steam, or fl ammable gas.
Install the unit where drainage does not cause any trouble.
Install the indoor unit, power supply cable, transmission cable, and remote controller
cable at least 1 m away from a television or radio receivers. The purpose of this is to

4. PIPE INSTALLATION
CAUTION
Be more careful that foreign matter (oil, water, etc.) does not enter the piping than with
refrigerant R410A models. Also, when storing the piping, securely seal the openings
by pinching, taping, etc.
While welding the pipes, be sure to blow dry nitrogen gas through them.
4.1. Selecting the pipe material
CAUTION
Do not use existing pipes from another refrigeration system or refrigerant.
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
incurs pressure higher than when using conventional (R22) refrigerant, it is necessary
to choose adequate materials.
Thicknesses of copper pipes used with R410A are as shown in the table.
•
Never use copper pipes thinner than those indicated in the table even if they are
•
available on the market.
Thicknesses of Annealed Copper Pipes (R410A)
Pipe outside diameter [mm (in.)] Thickness [mm]
6.35 (1/4) 0.80
9.52 (3/8) 0.80
12.70 (1/2) 0.80
