PRECAUTIONS FOR SAFETY

• Ensure that all Local, National and International regulations are satisfied.

• Read this “PRECAUTIONS FOR SAFETY” carefully before Installation.

• The precautions described below include the important items regarding safety. Observe them without fail.

• After the installation work, perform a trial operation to check for any problem.
Follow the Owner’s Manual to explain how to use and maintain the unit to the customer.

• Turn off the main power supply switch (or breaker) before the unit maintenance.

• Ask the customer to keep the Installation Manual together with the Owner’s Manual.

CAUTION New Refrigerant Air Conditioner Installation

• THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT

DESTROY OZONE LAYER.

The characteristics of R410A refrigerant are ; easy to absorb water, oxidizing membrane or oil, and its pressure is
approx. 1.6 times higher than that of refrigerant R22. Accompanied with the new refrigerant, refrigerating oil has also
been changed. Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating oil
does not enter the refrigerating cycle.

To prevent charging an incorrect refrigerant and refrigerating oil, the sizes of connecting sections of charging port of
the main unit and installation tools are charged from those for the conventional refrigerant.

Accordingly the exclusive tools are required for the new refrigerant (R410A).
For connecting pipes, use new and clean piping designed for R410A, and please care so that water or dust does

not enter. Moreover, do not use the existing piping because there are problems with pressure-resistance force and
impurity in it.

ENGLISH

CAUTION To Disconnect the Appliance from Main Power Supply

This appliance must be connected to the main power supply by means of a switch with a contact separation of at
least 3 mm.

WARNING

• Ask an authorized dealer or qualified installation professional to install/maintain the air conditioner.

Inappropriate installation may result in water leakage, electric shock or fire.

• Turn off the main power supply switch or breaker before attempting any electrical work.

Make sure all power switches are off. Failure to do so may cause electric shock.

• Connect the connecting wire correctly.

If the connecting wire is connected in a wrong way, electric parts may be damaged.

• When moving the air conditioner for the installation into another place, be very careful not to

enter any gaseous matter other than the specified refrigerant into the refrigeration cycle.

If air or any other gas is mixed in the refrigerant, the gas pressure in the refrigeration cycle becomes abnormally
high and it as a result causes pipe burst and injuries on persons.

• Do not modify this unit by removing any of the safety guards or by by-passing any of the safety

interlock switches.

• Exposure of unit to water or other moisture before installation may cause a short-circuit of

electrical parts.

Do not store it in a wet basement or expose to rain or water.

• After unpacking the unit, examine it carefully if there are possible damage.

• Do not install in a place that might increase the vibration of the unit.

• To avoid personal injury (with sharp edges), be careful when handling parts.

• Perform installation work properly according to the Installation Manual.

Inappropriate installation may result in water leakage, electric shock or fire.

• When the air conditioner is installed in a small room, provide appropriate measures to ensure that

the concentration of refrigerant leakage occur in the room does not exceed the critical level.

PRECAUTIONS FOR SAFETY

• Install the air conditioner securely in a location where the base can sustain the weight adequately.

• Perform the specified installation work to guard against an earthquake.

If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.

• If refrigerant gas has leaked during the installation work, ventilate the room immediately.

If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.

• After the installation work, confirm that refrigerant gas does not leak.

If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas might
generate.

• Electrical work must be performed by a qualified electrician in accordance with the Installation

Manual. Make sure the air conditioner uses an exclusive power supply.

An insufficient power supply capacity or inappropriate installation may cause fire.

• Use the specified wires for wiring connect the terminals securely fix. To prevent external forces

applied to the terminals from affecting the terminals.

• Conform to the regulations of the local electric company when wiring the power supply.

Inappropriate grounding may cause electric shock.

• Do not install the air conditioner in a location subject to a risk of exposure to a combustible gas.

If a combustible gas leaks, and stays around the unit, a fire may occur.

2

SELECTION OF INSTALLATION PLACE

WARNING

• Install the air conditioner where there is sufficient strength to weight of the unit.

If strength is insufficient, the unit may fall down resulting in human injury.

• Perform a specified installation work to guard against an earthquake.

An incomplete installation can cause accidents by the units failing and dropping.

CAUTION

• Do not install the air conditioner in a location subject to a risk of exposure to combustible gas.

Should the combustible gas leak and collect near the unit, fire may occur.

Upon approval of the customer, install the air conditioner in a place that satisfies the following
conditions.

• Place where the unit can be installed horizontally.

• Place where a sufficient servicing space can be ensured for safe maintenance and check.

• Place where drained water will not cause any problem.

Avoid installing in the following places.

• Place exposed to air with high salt content (seaside area), or place exposed to large quantities of sulfide gas

(hot spring). (Should the unit be used in these places, special protective measures are needed.)

• Place exposed to oil, vapor, oil smoke or corrosive gas.

• Place where organic solvent is used nearby.

• Place close to a machine generating high frequency.

• Place near door or window where may come to contact with the outside air of high humidity. (Dewing may be caused.)

• Place where special spray is frequently used.

• Place with poor ventilation.

Check method

On the remote controller (Main remote controller, Central control remote controller) and the interface P.C. board of
the outdoor unit (I/F), a check display LCD (Remote controller) or 7-segment display (on the outdoor interface P.C.
board) to display the operation is provided. Therefore the operation status can be known. Using this self-diagnosis
function, a trouble or position with error of the air conditioner can be found as shown in the table below.

Check code list

The following list shows each check code. Find the check contents from the list according to part to be checked.

• In case of check from indoor remote controller: See “Main remote controller display” in the list.

• In case of check from outdoor unit: See “Outdoor 7-segment display” in the list.

• In case of check from indoor unit with wireless remote controller: See “Sensor block display of receiving unit” in the list.

WARNINGS ON REFRIGERANT LEAKAGE

Check of Concentration Limit

The room in which the air conditioner is to be
installed requires a design that in the event of
refrigerant gas leaking out, its concentration will not
exceed a set limit.

The refrigerant R410A which is used in the air
conditioner is safe, without the toxicity or combustibility
of ammonia, and is not restricted by laws to be imposed
which protect the ozone layer. However, since it
contains more than air, it poses the risk of suffocation if
its concentration should rise excessively. Suffocation
from leakage of R410A is almost non-existent. With the
recent increase in the number of high concentration
buildings, however, the installation of multi air
conditioner systems is on the increase because of the
need for effective use of floor space, individual control,
energy conservation by curtailing heat and carrying
power etc.
Most importantly, the multi air conditioner system is able
to replenish a large amount of refrigerant compared with
conventional individual air conditioners. If a single unit of
the multi conditioner system is to be installed in a small
room, select a suitable model and installation procedure
so that if the refrigerant accidentally leaks out, its
concentration does not reach the limit (and in the event
of an emergency, measures can be made before injury
can occur).
In a room where the concentration may exceed the limit,
create an opening with adjacent rooms, or install
mechanical ventilation combined with a gas leak
detection device.
The concentration is as given below.

Total amount of refrigerant (kg)

Min. volume of the indoor unit installed room (m³)

≤ Concentration limit (kg/m³)

The concentration limit of R410A which is used in multi
air conditioners is 0.3kg/m³.

NOTE 1 :

If there are 2 or more refrigerating systems in a single
refrigerating device, the amounts of refrigerant should
be as charged in each independent device.

e.g., charged
amount (10kg)

Room A Room B Room C Room D Room E Room F

For the amount of charge in this example:

The possible amount of leaked refrigerant gas in
rooms A, B and C is 10kg.
The possible amount of leaked refrigerant gas in
rooms D, E and F is 15kg.

Outdoor unit

e.g.,
charged amount (15kg)

Indoor unit

Important

NOTE 2 :

The standards for minimum room volume are as follows.
(1) No partition (shaded portion)

(2) When there is an effective opening with the adjacent

room for ventilation of leaking refrigerant gas
(opening without a door, or an opening 0.15% or
larger than the respective floor spaces at the top or
bottom of the door).

Outdoor unit

Refrigerant piping

Indoor unit

(3) If an indoor unit is installed in each partitioned room

and the refrigerant piping is interconnected, the
smallest room of course becomes the object. But
when a mechanical ventilation is installed
interlocked with a gas leakage detector in the
smallest room where the density limit is exceeded,
the volume of the next smallest room becomes the
object.
