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 THIS PRODUCT
2.1. Precautions for using the R410A refrigerant
1
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.
