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,
explaintothecustomerhowtooperateandmaintaintheunit.
• 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.
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 pipe materials
that have been manufactured specifically for R410A use.
BecausethepressureoftheR410Arefrigerantisapproximately1.6timeshigherthan
the R22, failure to use dedicated pipe 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.
Excesspressurecancausearupture.
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.
Ifthereisarefrigerantleakage,makesurethatitdoesnotexceedtheconcentration
limit.
Ifarefrigerantleakageexceedstheconcentrationlimit,itcanleadtoaccidentssuchas
oxygenstarvation.
If a refrigerant leakage occurs during operation, immediately vacate the premises and
thoroughly ventilate the area.
Iftherefrigerantisexposedtofire,itwillcreateahazardousgas.
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
therearenoexternalforcesofthecablesappliedtotheterminalconnections.
Improperly connected or secured cables can cause serious accidents such as overheat-
ing the terminals, electric shock, or fire.
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.
Iftherefrigerantleaksintotheroomandbecomesexposedtoasourceoffiresuchasa
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.
Useonlyaspecifiedpowercable.Poorconnection,poorelectricalinsulation,andexceed-
ing 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.
Install a breaker to cut off all AC main current 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 pipes not attached
properly with the valves 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 before
you remove the refrigerant pipes. Do not remove the connection pipe while the com-
pressor is in operation with the valves open. This may cause abnormal pressure in the
refrigeration cycle that leads to breakage and even injury.
If there is a possibility of touching the fan during maintenance, make sure to turn OFF
the power before implementing the maintenance. Even if operations are suspended,
the fan of outdoor unit sometimes rotates, so if the fan rotates suddenly while in contact
with you may cause serious injury.
