1. SAFETY PRECAUTIONS

• Be sure to read this Installation manual thoroughly before installation.

• The warnings and precautions indicated in this Installation manual contain important

information pertaining to your safety. Be sure to observe them.

• After installing the unit, perform a test run to make sure the unit operates normally. Then,

explain to the customer how to operate and maintain the unit.

• Please pass this Installation manual together with the Operating manual to the customer.

Please ask the customer to keep the Operating manual and Installation manual at hand

for future reference during the moving or repair of the main unit.

WARNING This mark indicates procedures which, if improperly per-

formed, might lead to the death or serious injury of the user.

Consult the retail store or professional technicians to install the main unit according to

the Installation manual.

Improper installation will cause serious accidents such as refrigerant leakage, water

leakage, electric shock, and fire.

Manufacturer's guarantee will be invalid when instructions in the Installation manual are

ignored during installation.

For installation purposes, be sure to use the parts supplied by the manufacturer or other

prescribed parts.

Using non-specified parts will cause serious accidents such as falling unit, refrigerant

leakage, water leakage, electric shock, and fire.

To install a unit that uses the R410A refrigerant, use dedicated tools and piping materi-

als that have been manufactured specifically 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.

It will also cause serious accidents such as refrigerant leakage, water leakage, electric

shock, and fire.

Do not use this equipment with air or any other unspecified refrigerant in the refrigerant

lines.

Excess pressure can cause a rupture.

Be sure to install the unit as prescribed, so that it can withstand earthquakes and

typhoons or other strong winds.

Improper installation can cause the unit to topple or fall, or other accidents.

Ensure that the outdoor unit is securely installed at a place that can withstand the

weight of the unit.

Improper installation will cause injuries caused by falling unit.

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.

If a refrigerant leakage occurs during operation, immediately vacate the premises and

thoroughly ventilate the area.

If the refrigerant is exposed to fire, it will create a hazardous gas.

Electrical work must be performed in accordance with this Installation manual by a

person certified under the national or regional regulations. Be sure to use a dedicated

circuit for the unit.

An insufficient power supply circuit or improperly performed electrical work can cause

serious accidents such as electric shock or fire.

For wiring, use the prescribed type of cables, connect them securely, making sure that

there are no external forces of the cables applied to the terminal connections.

Improperly connected or secured cables can cause serious accidents such as overheat-

ing the terminals, electric shock, or fire.

Securely install the electrical box cover on the unit.

An improperly installed electrical box cover can cause serious accidents such as electric

shock or fire through exposure to dust or water.

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.

After the installation, make sure there is no refrigerant leakage.

If the refrigerant leaks into the room and becomes exposed to a source of fire such as a

fan heater, stove, or burner, it will create a hazardous gas.

Use a wall hole pipe. Otherwise, it may cause a short circuit.

Do not place the outdoor unit near the handrail of the balcony.

Children may climb onto the outdoor unit, lean over the handrail and fall over.

Use only a specified power cable. Poor connection, poor insulation, and exceeding the

allowable current will lead to electric shock and fire.

Attach the connecting cables securely to the terminal. Or secure it firmly with a “wiring

suppressor”.

Loose connection will lead to malfunction, electric shock, and fire.

Be sure to install an earth leakage breaker that can shut down all power supplies within

the system at the same time.

If you do not install a breaker, it may cause electric shock and fire.

During installation, make sure that the refrigerant pipe is attached firmly before you run

the compressor.

Do not operate the compressor under the condition of refrigerant piping not attached

properly with 2-way or 3-way valve open. This may cause abnormal pressure in the

refrigeration cycle that leads to rupture and even injury.

During the pump-down operation, make sure that the compressor is turned off be-

fore you remove the refrigerant piping. Do not remove the connection pipe while the

compressor is in operation with 2-way or 3-way valve open. This may cause abnormal

pressure in the refrigeration cycle that leads to breakage and even injury.
