2. ABOUT THIS PRODUCT
2.1. Precautions for using R410A refrigerant
The basic installation work procedures are the same as conventional refrigerant (R22)
models.
However, pay careful attention to the following points:
Since the working pressure is 1.6 times higher than that of conventional refrigerant (R22)
models, some of the piping and installation and service tools are special. (See the table
below.)
Especially, when replacing a conventional refrigerant (R22) model with a new refrigerant
R410A model, always replace the conventional piping and are nuts with the R410A
piping and are nuts.
Models that use refrigerant R410A have a di󰀨erent charging port thread diameter
to prevent erroneous charging with conventional refrigerant (R22) and for safety.
Therefore, check beforehand. [The charging port thread diameter for R410A is
1/2-20 UNF]
Be more careful that foreign matter (oil, water, etc.) does not enter the piping than with
refrigerant (R22) models. Also, when storing the piping ,securely seal the opening by
pinching, taping, etc.
When charging the refrigerant, take into account the slight change in the composition of
the gas and liquid phases. And always charge from the liquid phase where refrigerant
composition is stable.

2.2. Special tools for R410A refrigerant
Tool name Changes
Gauge manifold
Pressure is high and cannot be measured with a conventional
(R22) gauge. To prevent erroneous mixing of other refriger-
ants, the diameter of each port has been changed.
It is recommended to use the gauge with seals-0.1 to 5.3 MPa
(-1 to 53 bar) for high pressure.
-0.1 to 3.8 MPa (-1 to 38 bar) for low pressure.
Charge hose To increase pressure resistance, the hose material and base
size were changed.
Vacuum pump A conventional vacuum pump can be used by installing a
vacuum pump adapter.
Gas leakage detector Special gas leakage detector for HFC refrigerant R410A.
Copper pipes
It is necessary to use seamless copper pipes and it is desirable that the amount of re-
sidual oil is less than 40 mg/10 m. Do not use copper pipes having a collapsed, deformed
or discoloured portion (especially on the interior surface). Otherwise, the expansion value
or capillary tube may become blocked with contaminants.
As an air conditioner using R410A incurs pressure higher than when using R22, it is neces-
sary to choose adequate materials.

CONNECTION PIPE REQUIREMENT
WARNING
Do not use the existing (for R22) piping and are nuts.
If the existing materials are used, the pressure inside the refrigerant cycle will rise
and cause failure, injury, etc. (Use the special R410A materials.)
When installing and relocating the air conditioner, do not mix gases other
than the specied refrigerant (R410A) to enter the refrigerant cycle.
If air or other gas enters the refrigerant cycle, the pressure inside the cycle will rise
to an abnormally high value and cause failure, injury, etc.

4. SELECTING THE INSTALLATION LOCATION
Decide the mounting position with the customer as follows:
WARNING
Select installation locations that can properly support the weight of the indoor unit
and which will not amplify sound or vibration. If the installation location is not strong
enough, the indoor unit may fall and cause injuries.
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 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 a󰀨ect the equipment, such as
sulphuric 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 bres or
ammable dust, or volatile inammables such as paint thinner or gasoline.
If gas leaks and settles around the unit, it can cause a 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 ammable gas.
Install the unit where drainage does not cause any trouble.
Install the unit where ambient temperature does not reach 60°C or more. Take a
measure such as ventilation for an environment in which heat is retained.
If children under 10 years old may approach the unit, take preventive measures so
that they cannot reach the unit.
Install the indoor unit on the wall where the height from the oors more than 1.8 m.
(1) Install the indoor unit level on a strong wall which is not subject to vibration.
(2) The inlet and outlet ports should not be obstructed: the air should be able to blow all
over the room.
(3) Install the unit at a place near an power outlet or special branch circuit.
(4) Do not install the unit where it will be exposed to direct sunlight.
(5) Install the unit where connection to the outdoor unit is easy.
