8.1 BeforeTestRun
Recheckthatthereisnotanyproblemstothe
installation,anddonotperformthetestrununtilall
thefollowingcheckingpointshavebeencleared.
(1) Checktoensurethattherefrigerantpiping
andthetransitionwiringareconnectedtothe
samerefrigerantcyclesystem.Ifnot,itwill
causeanabnormaloperationandbreakage
ofinstruments.
(2) Checktoensurethattheelectricalresistance
ismorethan1megohm,bymeasuringthe
resistancebetweengroundandtheterminal
oftheelectricalparts.Ifnot,doNOToperate
thesystemuntiltheelectricalleakageis
foundandrepaired.Donotapplythehigh
voltagetotheterminalsforthetransmission
(TB2(A,B,1and2)).
8. Test Run
Testrunshouldbeperformedaccordingtothis
manualand“Installation&MaintenanceManual”of
theoutdoorunit.
Donotoperatethesystemuntilallthecheckpoints
havebeencleared.
● Check to ensure that the electrical resistance
is more than 1 megohm, by measuring the
resistance between ground and the terminal
of the electrical parts. If not, do not operate
the system until the electrical leakage is
found and repaired.
● Do not touch any of the parts at the discharge
gas side by hand while the system is running,
since the compressor chamber and the pipes
at the discharge side are heated higher than
90
o
C.
● Checktoensurethatthestopvalvesofthe
outdoorunitarefullyopened,andthenstartthe
system.
● Checktoensurethattheswitchonthemain
powersourcehasbeenONformorethan
12hours,towarmthecompressoroilbythe
crankcaseheater.
(3) Checktoensurethateachwireiscorrectly
connectedatthepowersource.Ifincorrectly
connected,theunitwillnotoperateand
thewiredcontrollerwillindicatethealarm
code“05”.Inthiscase,checkthephase
oftheprimarypowersourceaccordingto
theattachedattentionlabelontherearside
oftheservicecover.Then,performthe
reconnectionworkcorrectlywithturningOFF
thepowersupply.
(4) Checktoensurethatthemainpowersource
hasbeenturnedONformorethan12hours,
towarmthecompressoroilbythecrankcase
heater.
8.2 TestRun
Aftertheinstallationworkiscompleted,testrun
shouldbeperformed.
(1) Checktoensurethatstopvalves(gasand
liquid)oftheoutdoorunitarefullyopened.
(2) Inthecasethatindoorunitsareconnected
totheVRFsystem,performthetestrunof
theindoorunitonebyonesequentiallyand
thencheckaccordanceoftherefrigerant
pipingsystemandtheelectricalwiring
system.(Ifthemultipleindoorunitsare
operatedsimultaneously,thesystemcannot
beinspectedthesystemaccordance.)
(3) Performthetestrunaccordingtothe
followingprocedure.Ensurethatthetestrun
iscarriedoutwithoutanyproblem.
(a) Pressandhold“Menu”and“Back/Help”
simultaneouslyforatleast3seconds.
Thetestrunmenuwillbedisplayed.
1)Thetestrunmenuwillbedisplayed.
