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.

2. ABOUT THE UNIT

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 30in.Hg to 768 psi (–0.1 to 5.3 MPa)

and a low pressure display range 30in.Hg to 551 psi (–0.1

to 3.8 MPa).

To increase pressure resistance, the hose material and

Charging hose

base size were changed.

A conventional (R22) vacuum pump can be used by

installing a vacuum pump adapter.

Vacuum pump

Be sure that the pump oil does not backflow into the

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

–755 mmHg (–100.7 kPa).

Gas leakage detector

Special gas leakage detector for HFC refrigerant R410A.

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 to fall,

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.

Do not discard any accessories needed for installation 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

Select installation locations that can properly support the weight of the indoor. Install the

units securely so that they do not topple or fall.
