charge, indicated on the name plate of each compressor.
The oil level check must be done with the unit switched off,
when then suction and discharge pressures are equalised.
The oil level must be visible and above the middle of the
sight-glass in the oil equalisation line. If this is not the
case, there is an oil leak in the circuit. Search and repair the
leak, then recharge oil, so that it reaches a level between
the middle and three quarters of the sight-glass (unit in
vacuum).
ATTENTION: Too much oil in the circuit can cause a
unit defect. Please refer to the oil content in the physical
data table.
NOTE: Use only oils which have been approved for the
compressors. Never use oils which have been exposed to air.
