ESIE11-05 Test RunCommissioning and Test Run 2091.2 Procedure and OutlineFollow the following procedure to conduct the initial test operation after installation.1.2.1 Check Work Prior to Turn Power Supply OnCheck the stop valves forconditions.TerminalDryer(1000W)Check on piping / insulationmaterialsCheck the below items.• Power wiring• Control transmission wiringbetween units• Earth wire Is the wiring performed as specified? Is the designated wire used? Is the wiring screw of wiring not loose? Is the grounding work completed? Is the insulation of the main power supply circuit deteriorated?Use a 500V megger tester to measure the insulation. (*1)• Do not use a megger tester for other circuits than 200V (or240V) circuit.*1:Measure to be taken against decreased insulation resistance inthe compressor.If the compressor is left to stand foran extended period of time after therefrigerant charge with the stop valveopen and the power supply OFF, therefrigerant may be mixed in thecompressor, thus decreasing theinsulation resistance.Heat the compressor as shown onthe right and then recheck theinsulation. Is the pipe size proper? Is the pipe insulation material installed securely? Check to be sure the stop valves are under the followingconditions.Liquid-side stop valveOpenGas-side stop valveOpen
