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.
This mark indicates procedures which, if improperly
WARNING
performed, might lead to the death or serious injury of the
user.
Request your dealer or a professional installer to install the unit in accordance with
this Manual.
An improperly installed unit can cause serious accidents such as water leakage,
electric shock, or fi re.
If the 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.
Except for EMERGENCY, never turn off main as well as sub breaker of the indoor
units during operation. It will cause compressor failure as well as water leakage.
First, stop the indoor unit by operating the control unit, converter or external input
device and then cut the breaker. Make sure to operate through the control unit,
converter or external input device. When the breaker is designed, locate it at a place
where the users cannot start and stop in the daily work.
En-1
This mark indicates procedures which, if improperly performed,
CAUTION
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 earthed (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.
Never touch electrical components immediately after the power supply has been turned
off. Electric shock may occur. After turning off the power, always wait 5 minutes before
touching electrical components.
This unit contains no user-serviceable parts. Always consult authorized service person-
nel to repairs.
When moving, consult authorized service personnel for disconnection and installation
of the unit.

2. ABOUT THIS PRODUCT

2.1. Precautions for using the R410A refrigerant

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.
Tool name
Pressure is huge and cannot be measured with a conventional
(R22) gauge. To prevent erroneous mixing of other refrigerants,
the diameter of each port has been changed.
Gauge manifold
It is recommended to use a gauge manifold with a high pressure
display range -0.1 to 5.3 MPa and a low pressure display range
-0.1 to 3.8 MPa.
To increase pressure resistance, the hose material and base

size were changed.
A conventional (R22) vacuum pump can be used by installing
a vacuum pump adapter. Be sure that the pump oil does not
