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 custom-
er.
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.
This mark indicates procedures which, if improperly per-
WARNING
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 fi re.
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-specifi ed parts will cause serious accidents such as falling unit, refrigerant
leakage, water leakage, electric shock, and fi re.
To install a unit that uses the R410A refrigerant, use dedicated tools and piping materi-
als 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.
It will also cause serious accidents such as refrigerant leakage, water leakage, electric
shock, and fi re.
Do not use this equipment with air or any other unspecifi ed 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 fi re, it will create a hazardous gas.
Electrical work must be performed in accordance with this Installation manual by a
person certifi ed under the national or regional regulations. Be sure to use a dedicated
circuit for the unit.
An insuffi cient power supply circuit or improperly performed electrical work can cause
serious accidents such as electric shock or fi re.
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 fi re.
Securely install the electrical box cover on the unit.
An improperly installed electrical box cover can cause serious accidents such as electric
shock or fi re 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 fi re.
After the installation, make sure there is no refrigerant leakage.
If the refrigerant leaks into the room and becomes exposed to a source of fi re 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 specifi ed power cable. Poor connection, poor insulation, and exceeding the
allowable current will lead to electric shock and fi re.
Attach the connecting cables securely to the terminal. Or secure it fi rmly with a "wiring
suppressor".
Loose connection will lead to malfunction, electric shock, and fi re.
Install a breaker (Included with earth leakage circuit breaker) to cut off all AC main cur-
rent at the same time.
If you do not install a breaker, it may cause electric shock and fi re.
During installation, make sure that the refrigerant pipe is attached fi rmly 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.
