Trial Operation and Testing
1. Trial operation and testing
1-1 Measurethesupplyvoltageandmakesurethatitfallsinthespeciedrange.
1-2 Trialoperationshouldbecarriedoutineithercoolingorheatingmode.
•Incoolingmode,selectthelowestprogrammabletemperature;inheatingmode,selectthehighestprogrammable
temperature.
1)Trialoperationmaybedisabledineithermodedependingontheroomtemperature.
Usetheremotecontrollerfortrialoperationasdescribedbelow.
2)Aftertrialoperationiscomplete,setthetemperaturetoanormallevel(78°Fto82°F(26°Cto28°C)incoolingmode,
68°Fto75°F(20°Cto24°C)inheatingmode).
3)Forprotection,thesystemdisablesrestartoperationfor3minutesafteritisturnedoff.
1-3 Carryoutthetestoperationinaccordancewiththeoperationmanualtoensurethatallfunctionsandparts,
suchasnmovement,areworkingproperly.
•Theairconditionerrequires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.
Trial operation from remote controller
1)Press“ON/OFF”buttontoturnonthesystem.
2)Press“TEMP”button(2locations)and“MODE”buttonatthesametime.
3)Press“MODE”buttontwice.
(“T”willappearonthedisplaytoindicatethattrialoperationmodeisselected.)
4)Trialoperationterminatesinapprox.30minutesandswitchesintonormalmode.Toquitatrialoperation,press“ON/
OFF”button.
