Operation

The oil is separated from the discharge gas in the oil separator. The oil then passes into the separator oil reservoir

section. The oil reservoir section retains enough oil to supply the compressor oil/level regulators under all

conditions. From the oil reservoir section the oil is supplied to the compressor where it is fed to the compresso

through the capillary line.

Changing the Compressor Oil

Refrigeration oil is of bright, transparent appearance even after extended operation. However, various conditions

of the system can affect the oil such as insufficient evacuation of the system on start up, dirt from the pipework on

installation and excessive discharge temperatures. Initial Oil type is stated on the serial plate, for alternatives refer

to Hubbard Technical.

When the oil is seen to be in an unclean condition it should be changed to avoid consequential compressor

damage.
