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 performed,

WARNING

might lead to the death or serious injury of the user.

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.

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 controller, converter or external input device

and then cut the breaker.

Make sure to operate through the controller, 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, might

CAUTION

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 3 mm 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 THE UNIT

2.1. Precautions for using 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 leak, make sure that it does not exceed the concentration limit.

If a refrigerant leak 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 leak occurs during operation, immediately vacate the premises and

thoroughly ventilate the area. If the refrigerant comes in contact with a flame, it

produces a toxic gas.

2.2. Special tool for R410A

To install a unit that uses R410A refrigerant, use dedicated tools and piping materials

that have been manufactured specifically for R410A use. Because the pressure

of 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

The pressure in the refrigerant system is extremely 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

Gauge manifold

is recommended to use a gauge manifold with a high

pressure display range of -0.1 to 5.3 MPa and a low pres-

sure display range of -0.1 to 3.8 MPa.

To increase pressure resistance, the hose material and

base size were changed.

Charging hose

(The charging port thread diameter for R410A is 1/2 UNF

20 threads per inch.)

A conventional (R22) vacuum pump can be used by install-

ing a vacuum pump adapter.

Be sure that the pump oil does not backﬂ ow into the sys-

tem. Use one capable for vacuum suction of -100.7 kPa (5

Torr, -755 mmHg).
