1. Error Codes

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 ﬁ re. 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

ﬁ re.

If refrigerant leaks while work is being carried out, ventilate the area. If the refrigerant

comes in contact with a ﬂ ame, it produces a toxic gas.

Installation must be performed in accordance with the requirement of NEC(National

Electrical Code) and CEC(Canadian Electrical Code) 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.

2. ABOUT THIS PRODUCT

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 gauge. To

prevent erroneous mixing of other refrigerants, the diameter

Gauge manifold

of each port has been changed. It is recommended 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 dis-

play 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 threads per inch.)

A conventional vacuum pump can be used by installing a

vacuum pump adapter.

Vacuum pump

Be sure that the pump oil does not backﬂ ow into the sys-

tem. Use one capable for vacuum suction of 5 Torr, –755

mm Hg (–100.7 kPa).

Gas leakage detector

Special gas leakage detector for R410A refrigerant.

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.
