Vacuum Function
Display Message: PRESSURE TOO HIGH
BeforethemachinebeginsevacuatingtheA/Csystem,
itchecksforpressureinthesystemthatmightdamage
thevacuumpump.Ifpressuregreaterthan0.7baris
detected,themachinedisplays
PRESSURETOOHIGH
CHECKCONNECTIONS
SelectOK,andrecoverrefrigerantbeforeproceeding.
Display Message: VACUUM TIME X:XX MIN
Ifaleaktestwasprogrammed,andaleakisdetected,
themachinedisplays

LEAKTESTRESULTNEGATIVE
PressESCtoexittheautomaticsequenceandperform
neededrepairs.PressOKtocontinuetheautomatic
sequencedespitethefailedleaktest.
Toensureanaccurateleaktest,itisimperativethat
athoroughrecoveryandevacuationofthesystembe
performed.Duringtherecoveryprocess,coldspotscan
developintheA/Csystem.Pocketsofrefrigerantin
desiccantandinsystemoilwillcontinuetovaporizeas
theA/Csystemtemperatureequalizestowardambient.
Asthisoccurs,A/Csystempressurewillincrease,
whichmaybeinterpretedbythemachineasaleak.
Thiswillvarysomewhatwithambienttemperature
conditions.
