Heaters crankcase of the compressor and oil separator Heaters crankcase and the oil separator can prevent the dissolution of the oil with the refrigerant during the compressor stops, which could lead to a froth, and as a consequence, reduce the supply lubricating oil to moving parts. Meals served heaters during idle compressor. When conducting maintenance test the crankcase heaters and heating oil separator.Warning: Before starting the unit in the cold season, make sure that the heaters worked for at least 12 hours.DE-COMMISSIONINGStandstill Keep the compressor crankcase heater switched on until dismantling the compressor! This prevents increased refrigerant pollution in the compressor oil.Disassembling the unit or dismantling its components In case of disassembling, dismantling or replacement of electrical or pressure-bearing components:Warning! Electrical components may be live! Severe injuries are possible. Disconnect power supply voltage! Remove fuses!
