Safety Precautions
WARNING
•Afterconnectingallwiresbesuretoshapethecablessothattheydonotputunduestressontheelectricalcovers,
panelsorterminals.
Installcoversoverthewires.Incompletecoverinstallationmaycauseterminaloverheating,electricalshock,reorequipmentdamage.
•Wheninstallingorrelocatingthesystem,besuretokeeptherefrigerantcircuitfreefromallsubstancesotherthan
thespeciedrefrigerant(R410A),suchasair.
(Anypresenceofairorotherforeignsubstanceintherefrigerantcircuitcausesanabnormalpressurerisewhichmayresultinrupture,resulting
ininjury.)
•Duringpump-down,stopthecompressorbeforeremovingtherefrigerantpiping.
Ifthecompressorisstillrunningandthestopvalveisopenduringpump-down,airwillbesuckedinwhentherefrigerantpipingisremoved,
causingabnormallyhighpressurewhichcouldleadtoequipmentdamageorandpersonalinjury.
•Duringinstallation,attachtherefrigerantpipingsecurelybeforerunningthecompressor.
Iftherefrigerantpipesarenotattachedandthestopvalveisopenduringinstallation,airwillbesuckedinwhenthecompressorisrun,causing
abnormallyhighpressurewhichcouldleadtoequipmentdamageandpersonalinjury.
•Besuretoinstallagroundfaultcircuitinterrupterbreaker.
Failuretoinstallagroundfaultcircuitinterrupterbreakermayresultinelectricallyshocks,orrepersonalinjury.
CAUTION
•Donotinstalltheairconditionerwheregasleakagewouldbeexposedtoopenames.
Ifthegasleaksandbuildsuparoundtheunit,itmaycatchre.
•Establishdrainpipingaccordingtotheinstructionsofthismanual.
Inadequatepipingmaycausewaterdamage.
•Tightenthearenutaccordingtothespeciedtorque.Atorquewrenchshouldbeused.
Ifthearenutistightenedtoomuch,thearenutmaycrackovertimeandcauserefrigerantleakage.
•Donottouchtheheatexchangerns.
Improperhandlingmayresultininjury.
•Beverycarefulaboutproducttransportation.
SomeproductsusePPbandsforpackaging.DonotuseanyPPbandsforameansoftransportation.Itisdangerous.
•Makesuretoprovideforadequatemeasuresinordertopreventthattheoutdoorunitbeusedasashelterbysmall
animals.
Smallanimalsmakingcontactwithelectricalpartscancausemalfunctions,smokeorre.Pleaseinstructthecustomertokeeptheareaaround
theunitclean.
•Thetemperatureofrefrigerantcircuitwillbehigh,pleasekeeptheinter-unitwireawayfromcopperpipesthatare
notthermallyinsulated.
•ElectricalworkmustbeperformedinaccordancewiththeNEC/CECbyauthorizedpersonnelonly.
