whenthesystemisincoolingoperationor
atastop.
Whenthedrainpump(optionalaccessories)
isinoperation,thisnoiseisheard.
• Alow“sah”,“choro-choro”soundisheard
whiletheindoorunitisstopped.
Whentheotherindoorunitisinoperation,
thisnoiseisheard.Inordertopreventoiland
refrigerantfromremaininginthesystem,a
smallamountofrefrigerantiskeptowing.
• A“pishi-pishi”squeakingsoundisheardwhen
thesystemstopsafterheatingoperation.
Expansionandcontractionofplasticparts
causedbytemperaturechangemakethis
noise.
2 Indoorunit,outdoorunit
• Acontinuouslowhissingsoundisheard
whenthesystemisincoolingordefrost
operation.
Thisisthesoundofrefrigerantgasowing
throughbothindoorandoutdoorunits.
• Ahissingsoundwhichisheardatthestart
orimmediatelyafterstoppingoperationor
defrostoperation.
Thisisthenoiseofrefrigerantcausedby
owstoporowchange.
3 Outdoorunit
• Whenthetoneofoperatingnoisechanges.
Thisnoiseiscausedbythechangeof
frequency.
9.8 Dust comes out of the unit
• Whentheunitisusedforthersttimeinalongtime.
Thisisbecausedusthasgottenintotheunit.
9.9 The units can give off odours
• Theunitcanabsorbthesmellofrooms,
furniture,cigarettes,etc.,andthenemititagain.
9.10 The outdoor unit fan does not spin
• Thespeedofthefaniscontrolledinorderto
optimiseproductoperation.
9.11 The display shows “ ”
• Thisisthecaseimmediatelyafterthemain
powersupplyswitchisturnedonandmeans
thattheuserinterfaceisinnormalcondition.
Thiscontinuesforoneminute.
9.12 The compressor in the outdoor unit
does not stop after a short heating
operation
• Thisistopreventoilandrefrigerantfrom
remaininginthecompressor.Theunitwillstop
after5to10minutes.
9.13 The inside of an outdoor unit is warm
even when the unit has stopped
• Thisisbecausethecrankcaseheateris
warmingthecompressorsothatthecompressor
canstartsmoothly.
