repairs.
Case Description / what to check
Operation does not start soon.
•
WhenON/OFFbuttonwaspressed
soon after operation was stopped.
•Whenthemodewasreselected.
• This is to protect the air conditioner.
Youshouldwaitforabout3minutes.
Air does not come out.
 In HEAT operation
• Theairconditioneriswarmingup.Waitforabout1to4minutes.
• Duringdefrostingoperation,hotairdoesnotowoutoftheindoorunit.
 When the air conditioner operates immediately after the circuit breaker is turned on
• Theairconditionerispreparingtooperate.Waitforabout3to20minutes.
The heating operation stops suddenly
and a  owing sound is heard.
• Thesystemistakingawaythefrostontheoutdoorunit.
Youshouldwaitforabout4to12minutes.
The outdoor unit emits water or
steam.
 InHEATmode
• The frost on the outdoor unit melts into water or steam when the air conditioner is in
defrost operation.
 InCOOLorDRYmode
• Moisture in the air condenses into water on the cool surface of outdoor unit piping and drips.
Mist comes out of the indoor unit.
 Thishappenswhentheairintheroomiscooledintomistbythecoldairowduringcooling
operation.
The indoor unit gives out odour.
 This happens when smells of the room, furniture, or cigarettes are absorbed into the unit
anddischargedwiththeairow.
(Ifthishappens,werecommendyoutohavetheindoorunitwashedbyatechnician.
Consult the service shop where you bought the air conditioner.)
The outdoor fan rotates while the
air conditioner is not in operation.
 Afteroperationisstopped:
• Theoutdoorfancontinuesrotatingforanother30secondsforsystemprotection.
 Whiletheairconditionerisnotinoperation:
• Whentheoutdoortemperatureisveryhigh,theoutdoorfanstartsrotatingforsystemprotection.
The operation stopped suddenly.
(OPERATION lamp is on.)
 Forsystemprotection,theairconditionermaystopoperatingonasuddenlargevoltageuctuation.
Itautomaticallyresumesoperationinabout3minutes.
The air conditioner does not
operate.
(OPERATION lamp is off.)
• Hasn’tabreakerturnedOFForafuseblown?
• Isn’titapowerfailure?
• Arebatteriessetintheremotecontroller?
• Isthetimersettingcorrect?
Cooling (Heating) effect is poor.
• Aretheairltersclean?
• Isthereanythingblockingtheairinletortheoutletoftheindoorandtheoutdoorunits?
• Isthetemperaturesettingappropriate?
• Arethewindowsanddoorsclosed?
• Aretheairowrateandtheairdirectionsetappropriately?
Operation stops suddenly.
(OPERATION lamp  ashes.)
• Aretheairltersclean?
• Isthereanythingblockingtheairinletortheoutletoftheindoorandtheoutdoorunits?
CleantheairltersortakeallobstaclesawayandturnthebreakerOFF.ThenturnitON
againandtryoperatingtheairconditionerwiththeremotecontroller.Ifthelampstillblinks,
call the service shop where you bought the air conditioner.
• Areoperationmodesallthesameforindoorunitsconnectedtooutdoorunitsinthemulti system?
Ifnot,setallindoorunitstothesameoperationmodeandconrmthatthelampsblink.
Moreover,whentheoperationmodeisin“AUTO”,setallindoorunitoperationmodesto
“COOL”or“HEAT”foramomentandcheckagainthatthelampsarenormal.
Ifthelampsstopblinkingaftertheabovesteps,thereisnomalfunction.
