This installation manual deals with an indoor unit installation only. For an outdoor unit installation, refer to page 18.
SAFETY PRECAUTIONS
• Before installation, read the “SAFETY PRECAUTIONS” carefully and strictly follow it during the installa-
tion work in order to protect yourself.
•
The precautionary items mentioned below are distinguished into two levels,
WARNING
and
CAUTION
.
WARNING
Indicates a potentially hazardous situation which, if not avoided, can result in serious con-
sequences such as death or severe injury.
CAUTION
Indicates a potentially hazardous situation which, if not avoided, can result in personal in-
jury or property damage.
Both mention the important items to protect your health and safety. Therefore, strictly follow them by any means.
• Be sureto conrmnooperationproblemon theequipment aftercompletingtheinstallation.If unusual
noise can be heard during the test run, consult the dealer.
• Be sure to explain the operating methods as well as the maintenance methods of this equipment to the
user according to the user’s manual.
• Be sure to keep the installation manual together with user’s manual at a place where it is easily accessi-
ble to the user any time. Moreover, ask the user to hand the manuals to a new user, whenever required.
WARNING
• Be sure to use only for residential purpose. If this unit is installed in inferior environment such as machine shop, vehicle (like ship), warehouse,
etc., it can malfunction.
• Installationmustbecarriedoutbythequaliedinstallercompletelyinaccor-
dance with the installation manual.
 Installationbynonqualiedpersonorincorrectinstallationcancauseserioustroublessuchaswater
leak,electricshock,reandpersonalinjury.
•
Be sure to wear protective goggles and gloves while performing installation work.
 Impropersafetymeasurescanresultinpersonalinjury. • Usetheoriginalaccessoriesandthespeciedcomponentsfortheinstallation.  Usingpartsotherthanthoseprescribedmaycausewaterleak,electricshock,reandpersonalinjury. •
Donotinstalltheunitnearthelocationwhereleakageofammablegasescanoccur.
 Ifleakedgasesaccumulatearoundtheunit,itcancausereresultinginpropertydamageandper-
sonalinjury.
• When installing the unit in small rooms, make sure that refrigerant density
does not exceed the limit (Reference: ISO5149) in the event of leakage.
If refrigerant density exceeds the limit, consult the dealer and install the ventilation system. Otherwise lack of oxygen can occur resulting in serious accident. • Install the unit in a location where unit will remain stable, horizontal and free
of any vibration transmission.
 Unsuitableinstallationlocationcancausetheunittofallresultinginmaterialdamageandpersonalinjury. • Do not run the unit with removed panels or protections.  Touchingrotatingequipments,hotsurfacesorhighvoltagepartscancausepersonalinjurydueto
entrapment, burn or electric shock.
• ThisunitisdesignedspecicallyforR410A.  Usinganyotherrefrigerantcancauseunitfailureandpersonalinjury. • DonotventR410Aintoatmosphere. R410AisauorinatedgreenhousegaswithaGlobalWarningPotential(GWP)=2088. • Make sure that no air enters the refrigerant circuit when the unit is installed
and removed.
If air enters the refrigerant circuit, the pressure in the refrigerant circuit will become too high, which
cancauseburstandpersonalinjury.
• Besuretousetheprescribedpipes,arenutsandtoolsforR410A. Usingexistingparts(forR22orR407C)cancauserefrigerantcircuitburstresultinginunitfailureand
personalinjury.
• Be sure to connect both liquid and gas connecting pipes properly before op-
erating the compressor.
Do not open the liquid and gas service valves before completing piping work,
and evacuation.
If the compressor is operated when connecting pipes are not connected and service valves are open,
air can be sucked into the refrigerant circuit which can cause anomalous high pressure resulting in burstorpersonalinjury.
• Besuretotightenthearenutstospeciedtorqueusingthetorquewrench.  Tighteningarenutswithexcesstorquecancauseburstandrefrigerantleakageafteralongperiod.
• During pump down work, be sure to stop the compressor before closing ser-
vice valves and removing connecting pipes.
If the connecting pipes are removed when the compressor is in operation and service valves are
open, air can be sucked into the refrigerant circuit which can cause anomalous high pressure result- inginburstorpersonalinjury.
• In the event of refrigerant leakage during installation, be sure to ventilate the
working area properly.
Iftherefrigerantcomesintocontactwithnakedames,poisonousgaseswillbeproduced.
• Electricalworkmustbecarriedoutbythequaliedelectrician,strictlyinac-
cordance with national or regional electricity regulations.
 Incorrectinstallationcancauseelectricshock,reorpersonalinjury. • Make sure that earth leakage breaker and circuit breaker of appropriate ca-
pacities are installed.
 Circuitbreakershouldbeabletodisconnectallpolesunderovercurrent.Absenceofappropriate
breakerscancauseelectricshock,personalinjuryorpropertydamage.
• Be sure to switch off the power source in the event of installation, mainte-
nance or service.
 Ifthepowersourceisnotswitchedoff,thereisariskofelectricshock,unitfailureorpersonalinjury. • Be sure to tighten the cables securely in terminal block and relieve the ca-
bles properly to prevent overloading the terminal blocks.
Looseconnectionsorcablemountingscancauseanomalousheatproductionorre. • Do not process, splice or modify the power cable, or share the socket with
other power plugs.
 Improperpowercableorpowerplugcancausereorelectricshockduetopoorconnection,insuf-
cientinsulationorover-current.
• Do not perform any change in protective device or its setup condition yourself.  Changingprotectivedevicespecicationscancauseelectricshock,reorburst. • Be sure to clamp the cables properly so that they do not touch any internal
component of the unit.
 Ifcablestouchanyinternalcomponent,itcancauseoverheatingandre. • Be sure to install service cover properly.  Improperinstallationcancauseelectricshockorreduetointrusionofdustorwater. • Be sure to use the prescribed power and connecting cables for electrical work.  Usingimpropercablescancauseelectricleak,anomalousheatproductionorre. • This appliance must be connected to main power source by means of a cir-
cuit breaker or switch with a contact separation of at least 3mm.
 Improperelectricalworkcancauseunitfailureorpersonalinjury. •
Whenpluggingthisunit,aplugconformingtothenormIEC60884-1mustbeused.
 Usingimproperplugcancauseelectricshockorre. • Be sure to connect the power source cable with power source properly.  Improperconnectioncancauseintrusionofdustorwaterresultinginelectricshockorre.
