Samsung MCU-Y6NEE Installation Manual

155. Select the insulation of the refrigerant pipe. Insulate the gas side and liquid side pipe referring to the thickness according to the pipe size. Indoor temperature of 30°C and humidity of 85% is the standard condition. If install in a high humidity condition, use one grade thickerinsulator by referring to the table below. If installing in an unfavorable conditions,use thicker one. Insulator’s heat-resistance temperature should be more than 120°C.Pipe Pipe sizeInsulation Type(Heating/Cooling)RemarksStandard[30°C, 85%]High humidity[30°C, over85%]EPDM, NBRLiquidpipeø6.35~ø9.52 9t 9tInternal temperatureis higher than 120°Cø12.70~ø50.80 13t 13tGasPipeø6.35 13t 19tø9.5219t25tø12.70ø15.88ø19.05ø22.23ø25.40ø28.5832tø31.75ø38.10ø44.45ø50.80 25t 38tRefrigerant pipe before EEV kit and MCU or without EEV kit and MCU You can contact the gas side and liquid side pipes but the pipesshould not be pressed. When contacting the gas side and gas side pipe, use 1 grade thickerinsulator.Refrigerant pipe after EEV kit and MCU Install the gas side and liquid side pipes, leave 10mm of space. When contacting the gas side and liquid side pipe, use 1 gradethicker insulation.Gas pipeLiquid pipeInsulationInsulationGas pipe10mmLiquid pipe10mm 10mm10mm• Install the insulation not to get wider and use the adhesives on the connection part of it toprevent moisture from entering.• Wind the refrigerant pipe with insulation tapeif it is exposed to outside sunlight.• Install the refrigerant pipe respecting that theinsulation does not get thinner on the bentpart or hanger of pipe.• Add the additional insulationif the insulation plate gets thinner.Additional insulationHangerRefrigerant pipe insulationa×3a
