2. ABOUT THIS PRODUCT

2.1. Precautions for using R410A refrigerant

WARNING

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 tools for R410A

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.

WARNING

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 fire. 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 fire.

If refrigerant leaks while work is being carried out, ventilate the area. If the refrigerant
comes in contact with a flame, 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.

This mark indicates procedures which, if improperly performed,
might lead to the death or serious injury of the user.

WARNING

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
fire.

ants, the diameter of each port has been changed.
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 vacuum pump can be used by installing a
vacuum pump adapter.

• A conventional vacuum pump can be used by installing a
vacuum pump adapter.

• Be sure that the pump oil does not back flow into the
system. Use one capable for vacuum suction of -100.7kPa
(5 Ton, -755mmHg).

3. INSTALLATION WORK

Correct initial installation location is important because it is difficult to move unit after it is
installed.

3.1. Selecting an installation location

Decide the mounting position together with the customer as follows.

WARNING

Select installation locations that can properly support the weight of the indoor unit.
Install the units securely so that they do not topple or fall.

CAUTION

Do not install the indoor 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 filled 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 affect the equipment, such as sulfuric
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 fibers or
flammable dust, or volatile inflammables such as paint thinner or gasoline. If gas leaks
and settles around the unit, it can cause a fire.

• 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 flammable gas.

Install the unit where drainage does not cause any trouble.

Install the indoor unit, power supply cable, transmission cable, and remote controller
cable at least 1 m away from a television or radio receivers. The purpose of this is to
prevent TV reception interference or radio noise. (Even if they are installed more than 1
m apart, you could still receive noise under some signal conditions.)

If children under 10 years old may approach the unit, take preventive measures so that
they cannot reach the unit.

Take precautions to prevent the unit from falling.

(1) Install the indoor unit on a place having a sufficient strength so that it withstands

against the weight of the indoor unit.

(2) The inlet and outlet ports should not be obstructed; the air should be able to blow all

over the room.
(3) Leave the space required to service the air conditioner.
(4) Install the unit where connection to the outdoor unit (or RB unit) is easy.
(5) Install the unit where the connection pipe can be easily installed.
(6) Install the unit where the drain pipe can be easily installed.
(7) Install the unit where noise and vibrations are not amplified.
(8) Take servicing, etc., into consideration and leave the spaces. Also install the unit

where the filter can be removed.
(9) Do not install the unit where it will be exposed to direct sunlight.

3.3.2 Installing the wall hook bracket

• Refer to figure below for the installation hole dimensions of the wall hook bracket.

• Before fastening the wall hook bracket to the wall with the screws, level it by tapping the
hook at the center of bracket to the wall with the handle of a screwdriver.

(1) Fasten the wall hook bracket to the wall with 5 or more screws and anchor bolts

through the holes near the outer edge of the bracket.
(Do not install the wall hook bracket at only 1 place or at an angle.)

(2) For a concrete wall, embed anchor bolts (10 mm dia.) into the wall at the wall hook

bracket holes.
(Allow the anchor bolts to stick out at least 18 mm from the wall. Use 2 bolts for flat

concrete wall and 4 bolts for blister concrete wall.)
(3) Install the nuts to the anchor bolts through the wall hook bracket.
(4) Finally tighten the bolts and wood screws after confirming, using the level indicator,

that the clamp is horizontal.

WARNING

Install the wall hook bracket level, both horizontally and vertically. If the wall hook
bracket is tilted, wa ter will drip to the floor.

As the weight of the indoor unit is 15 to 18 kg, it should be installed after properly exam­ining the place where it is in tended to be in stalled. If the place is not strong enough, a
plank or girder should be used to make the place sufficiently strong so that the wall can
support the weight.

3.3.5 Forming the drain hose and pipe

CAUTION

Insert drain hose and drain cap securely. Drain should slope down to avoid water leak­age.

When inserting the drain hose, no other material than water should be applied. Applica­tion of other material than water will cause deterioration of the hose, and may cause
water leakage.

After you remove a drain hose, be sure to attach the drain cap.
When you secure the piping and drain hose with tape, arrange the drain hose so that it

is at the bottom of the piping.
For drain hose piping in low temperature environment, you need to apply freeze protec-

tion to prevent a frozen drain hose.
After cooling operation is performed in low temperature environment, (when outdoor
temperature under 0 °C,) water in the drain hose could be frozen. Frozen drain water
will block the water flow in the hose, and may cause water leakage at the indoor unit.

[For (A) Rear piping, (B) Right piping and (C) Bottom piping]

(1) Install the indoor unit piping in

the direction of the wall hole
and bind the drain hose and
pipe together with vinyl tape.

(2) Install the piping so that the

drain hose is at the bottom.

(3) Wrap the pipe of the indoor unit

that visible from the outside
with decorative tape.

(4) For right or bottom outlet

piping, cut off the piping outlet
cutting groove with a hacksaw.

4. PIPE INSTALLATION

CAUTION

Be more careful that foreign matter (oil, water, etc.) does not enter the piping than with
refrigerant R410A models. Also, when storing the piping, securely seal the openings by
pinching, taping, etc.

While welding the pipes, be sure to blow dry nitrogen gas through them.

4.1. Selecting the pipe material

CAUTION

Do not use existing pipes from another refrigeration system or refrigerant.

Use pipes that have clean external and internal sides without any contamination which
may cause trouble during use, such as sulfur, oxide, dust, cutting waste, oil, or water.

It is necessary to use seamless copper pipes.
Material : Phosphor deoxidized seamless copper pipes
It is desirable that the amount of residual oil is less than 40 mg/10 m.

Do not use copper pipes that have a collapsed, deformed, or discolored portion (es­pecially on the interior surface). Otherwise, the expansion valve or capillary tube may
become blocked with contaminants.

Improper pipe selection will degrade performance. As an air conditioner using R410A
incurs pressure higher than when using conventional (R22) 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 those indicated in the table even if they are avail­able on the market.
