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 refrigerants,

the diameter of each port has been changed. It is recom-

Gauge manifold

mended to use a gauge manifold with a high pressure

display range of 30 in.Hg to 768 psi (–0.1 to 5.3 MPa)

and a low pressure display range of 30 in.Hg to 551 psi

(–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 inch.)

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

ing a vacuum pump adapter.

Be sure that the pump oil does not backflow into the

Vacuum pump

system. Use one capable for vacuum suction of 5 Torr,

–755 mmHg (–100.7 kPa).

2.3. Accessories

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.

• The following installation parts are furnished. Use them as required.

• Keep the Installation Manual in a safe place and do not discard any other accessories

until the installation work has been completed.

3. INSTALLATION WORK

Correct initial installation location is important because it is difﬁ cult to move unit after it is

installed.

3.1. Selecting an installation location

Decide the mounting position together with the customer as follows.

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.

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 ﬁ lled 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 ﬁ bers or

ﬂ ammable dust, or volatile inﬂ ammables such as paint thinner or gasoline. If gas

leaks and settles around the unit, it can cause a ﬁ re.

• 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 ﬂ ammable gas.

Install the unit where drainage does not cause any trouble.

Install the indoor unit, outdoor unit, power supply cable, transmission cable, and

remote controller cable at least 40 in. (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 40 in. (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.
