InstructionsPCH COMPRESSORS1 | © Danfoss | DCS (CC)| 2018.048510287P01B - FRCC.PI.054.A2.02The compressor must only be used for its designed purpose(s) and wit-hin its scope of application (refer to «operating limits»).Consult Application guidelines and datasheet available from cc.danfoss.comUnder all circumstances, the EN378 (or other applicable local safetyregulation) requirements must be fulfilled.The compressor is delivered under nitrogen gas pressure (between 0.3and 0.7 bar) and hence cannot be connected as is; refer to the «assem-bly» section for further details.The compressor must be handled with caution in the vertical position (maxi-mum offset from the vertical : 15°)This Danfoss scroll compressor motor is protected by an external module protecting against phase loss/reversal, overheating and high current draw.MPMSSSHCCSSLPSUNITCONTROLLERKMLegend :Fuses ...............................................................................

Use thededicated handles in the packaging. Use thecompressor lifting lug and use appropriate andsafe lifting equipment.•Store and transport the compressor in anupright position.•Store the compressor between Ts min and Tsmax values for LP side indicated on compressornameplate.•Don’t expose the compressor and the packa-ging to rain or corrosive atmosphere.3 – Safety measures before assemblyNever use the compressor in a flammableatmosphere.Check before assembly that thecompressor does not show any obvious signs ofdeterioration that could have occurred duringinappropriate transportation, handling or sto-rage•The compressor ambient temperature shallnot exceed Ts max value for LP side indicatedon compressor nameplate during off-cycle.•Mount the compressor on a horizontal flatsurface with less than 3° slope. The compres-sor must be mounted with flexible grommet(single applications). Refer to the PCH guide-line to know the tightening torques that mustbe applied.•Verify that the power supply corresponds tothe compressor motor characteristics (seenameplate).•When installing PCH, use equipment specifi-cally reserved for HFC refrigerants which wasnever used for CFC or HCFC refrigerants.•Use clean and dehydrated refrigeration-gradecopper tubes and silver alloy brazing material.•Use clean and dehydrated system components.•The piping connected to the compressor must beflexible in 3 dimensions to dampen vibrations.ADEFBC
