9.9 LUBRICATING OIL FILLING IN THE CIRCUIT
WARNING!
The quantity of lubricating oil necessary for the system to operate must be checked in ALL
units, even those with the oil separator.
Correct lubricating oil charging is crucial for good operation of the direct expansion circuit, in fact, having no lubricating oil
causes problems to the circuit, such as mechanical breakage of the compressor.
