Outline the procedure for adding oil to a semi-hermetic compressor without opening the compressor
What will be an ideal response?
The oil line must have a manual valve to control flow through the oil line. One end of the oil hose is connected to the suction service valve; the other is submerged in the oil container.
Purge the air from the oil line by blowing a small amount of refrigerant vapor through it into the oil.
Frontseat the suction service valve and operate the compressor long enough to create a slight vacuum.
Oil is added by opening the control valve in the oil line.
Close the control valve in the oil line when the correct amount of oil has been added.
Backseat the suction service valve and remove the oil hose.
