Trial Operation and Testing
1� Trial operation and testing
• TrialoperationshouldbecarriedoutineitherCOOLorHEAToperation.
1-1� Measure the supply voltage and make sure that it is within the specifi ed range.
1-2� In COOL operation, select the lowest programmable temperature;
in HEAT operation, select the highest programmable temperature�
1-3� Carry out the trial operation in accordance with the operation manual to ensure
that all functions and parts, such as fl ap movement, are working properly.
• Forprotection,thesystemdisablesrestartoperationfor3minutesafteritisturnedoff.
1-4� After trial operation is complete, set the temperature to a normal level (78°F
to 82°F (26°C to 28°C) in COOL operation, 68°F to 75°F (20°C to 24°C) in HEAT
operation)�
• WhenoperatingtheairconditionerinCOOLoperationinwinter,
orHEAToperationinsummer,setittothetrialoperationmodeusing
thefollowingmethod.
1)Press
, and atthesametime.
2)Press
,thenselect ,press .
3)Press
or toturnonthesystem.
• Trialoperationwillstopautomaticallyafterabout30minutes.
Tostoptheoperation,press
.
• Someofthefunctionscannotbeusedinthetrialoperationmode.
HEATPUMPmodel COOLINGONLYmodel
• Theairconditionerdrawsasmallamountofpowerinitsstandbymode.Ifthesystemisnottobeusedforsometime
afterinstallation,shutoffthecircuitbreakertoeliminateunnecessarypowerconsumption.
• Ifthecircuitbreakertripstoshutoffthepowertotheairconditioner,thesystemwillrestoretheoriginaloperationmode
whenthecircuitbreakerisopenedagain.
