1. SAFETY PRECAUTIONS
Be sure to read this Manual thoroughly before installation.
The warnings and precautions indicated in this Manual contain important information
pertaining to your safety. Be sure to observe them.
Hand this Manual, together with the Operating Manual, to the customer. Request the
customer to keep them on hand for future use, such as for relocating or repairing the unit.
After installation, explain correct operation to the customer, using the operating manual.
WARNING This mark indicates procedures which, if improperly performed,
might lead to the death or serious injury of the user.
Never touch electrical components immediately after the power supply has been turned
off. Electrical shock may occur. After turning off the power, always wait 5 minutes or
more before touching electrical components.
Request your dealer or a professional installer to install the indoor unit in accordance
with this Installation Manual. An improperly installed unit can cause serious accidents
such as water leakage, electric shock, or fi re. If the indoor unit is installed in disregard
of the instructions in the Installation Manual, it will void the manufacturer’s warranty.
Do not turn ON the power until all work has been completed. Turning ON the power
before the work is completed can cause serious accidents such as electric shock or fi re.
If refrigerant leaks while work is being carried out, ventilate the area. If the refrigerant
comes in contact with a fl ame, it produces a toxic gas.
Installation work must be performed in accordance with national wiring standards by
authorized personnel only.
During installation, make sure that the refrigerant pipe is attached fi rmly before you run
the compressor.
Do not operate the compressor under the condition of refrigerant piping not attached
properly with 2-way or 3-way valve open. This may cause abnormal pressure in the
refrigeration cycle that leads to breakage and even injury.
When installing and relocating the air conditioner, do not mix gases other than the
specifi 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 breakage, injury, etc.
Do not remove the connection pipe while the compressor is in operation with 2-way or
3-way valve open.
This may cause abnormal pressure in the refrigeration cycle that leads to breakage and
even injury.
For the air conditioner to operate satisfactorily, install it as outlined in this installation
manual.
Connect the indoor unit and outdoor unit with the air conditioner piping and cable
available standards parts.
This installation manual describes the correct connections using the installation set
available from our standard parts.
Also, do not use an extension cable.
Do not purge the air with refrigerants but use a vacuum pump to vacuum the
installation.
There is not extra refrigerant in the outdoor unit for air purging.
Use a vacuum pump for R410A exclusively.
Using the same vacuum pump for different refrigerants may damage the vacuum pump
or the unit.
Use a clean gauge manifold and charging hose for R410A exclusively.
During the pump-down operation, make sure that the compressor is turned off before
you remove the refrigerant piping.
Do not remove the connection pipe while the compressor is in operation with 2-way or
3-way valve open.
This may cause abnormal pressure in the refrigeration cycle that leads to breakage and
even injury.
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 qualifi ed personnel with a capacity certifi cate for handling
refrigerant fl uids. Refer to regulation and laws in use on installation place.
The 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
atmosphere.
This unit contains no user-serviceable parts. Always consult authorized service
personnel to repairs.
When moving, consult authorized service personnel for disconnection and installation
of the unit.
Children should be monitored to ensure they do not play with the device.
This appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concerning use of the appliance by a
person responsible for their safety. Children should be supervised to ensure that they
do not play with the appliance.
2. ABOUT THIS PRODUCT
2. 1. Precautions for using R410A refrigerant
WARNING
The basic installation work procedures are the same as conventional refrigerant 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 fl are nuts with
the R410A piping and fl are nuts.
• Models that use refrigerant R410A have a different 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 UNF 20 threads per inch.]
• Be careful that foreign matter (oil, water, etc.) does not enter the piping than with
refrigerant models. Also, when storing the piping, securely seal the openings 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
Tool name Contents of change
Gauge manifold
Pressure is high and cannot be measured with a conventional
gauge. To prevent erroneous mixing of other refrigerants, the
diameter of each port has been changed.
It is recommended 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 residual
oil is less than 40 mg/10 m. Do not use copper pipes having a collapsed, deformed or
discolored portion (especially on the interior surface). Otherwise, the expansion valve or
capillary tube may become blocked with contaminants.
As an air conditioner using R410A incurs pressure higher than when using conventional
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 that in the table even when it is available on the market.
Thicknesses of Annealed Copper Pipes (R410A)
Pipe outside diameter Thickness
6.35 mm (1/4 in.) 0.80 mm
9.52 mm (3/8 in.) 0.80 mm
12.70 mm (1/2 in.) 0.80 mm
15.88 mm (5/8 in.) 1.00 mm
19.05 mm (3/4 in.) 1.20 mm
2. 3. Accessories
WARNING
For installation purposes, be sure to use the parts supplied by the manufacturer or other
prescribed parts. The use of non-prescribed parts can cause serious accidents such as
the unit falling, water leakage, electric shock, or fi re.
Do not throw away the connecting parts until the installation has been complete.
