6.10.2 Trial Operation
1.Measurethesupplyvoltageandmakesurethatitfallswithinthespeciedrange.
2. Trial operation should be carried out in either cooling or heating operation.
3. Carry out the trial operation in accordance with the operation manual to ensure that all functions and parts,
such as louver movement, are working properly.
•Theairconditionerrequiresasmallamountofpowerin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backsupthe
operation mode. The system then restarts operation with the previous operation mode when the
circuit breaker is restored. [details refer to section 2.14 Auto Random Restart]
4.Incoolingoperation,selectthelowestprogrammabletemperature;inheatingoperation,selectthehighest
programmable temperature.
•Trialoperationmaybedisableineitheroperationmodedependingontheroomtemperature.
•Aftertrialoperationiscomplete,setthetemperaturetoanormallevel.
[26-28°C(78.8–82.4°F)incooling,20-24°C(68–75.2°F)inheating]
•Forprotection,thesystemdoesnotstartfor3minutesafteritisturnedoff.

6.10.4 Silicon Grease on Power Transistor / Diode Bridge
Applythespeciedsilicongreasetotheheatradiationpartofapowertransistor/diodebridgewhenyou
replace an outdoor unit PCB. The silicon grease encourages the heat radiation of a power transistor / diode
bridge.
<Details>
1. Wipe off the old silicon grease completely.
2. Apply the silicon grease evenly. See the illustration below for examples of application.
3. Tighten the screws of the power transistor / diode bridge.
4.Makesurethattheheatradiationpartsarermlycontactedtotheradiationn.
Note: smoke emission may be caused by bad heat radiation when the silicon grease is not appropriately applied.
