  1. Check level of lubricating oil in the compressor, add oil if necessary and must be visible in the sight glass.
  2. Start the condenser cooling system and compressor cooling if applicable.
  3. Open compressor discharge stop valve.
  4. Set the capacity regulator to minimum, and to avoid excessive pressure reduction in the compressor when starting-up, the suction stop valve must be opened a couple of turns to prevent the oil foaming.
  5. Open the king valve or liquid valve.
  6. Start the compressor motor - check suction and oil pressure.
  7. Adjust the expansion valve until the suction pressure correspond to the temperature desired for the cooled compartment.
  8. Check to ensure that level of oil is normal, while operation and oil return flow from the oil separator is functioning.
  9. Do not leave the compressor during first 15 minutes of operation until its condition is normal.
