2. GENERAL DESCRIPTION [Daily Operating Components]
● Verify that the oil level of the lubricating oil is
between the red lines during operation.
Lubricating oil circulates in the cooler and piping during
operation, so the position of the oil level differs when the
compressor is running and when it is off. The level rises
when the compressor stops running.
