Oil charge
Usually, the compressor is delivered without any oil in the crankcase. As a principal rule, the
amount of oil indicated in
should be charged to the compressor.
After a few hours of operation, the compressor must be recharged with oil as part of the oil has
been absorbed by the refrigerant. This particularly applies to HFC and HCFC refrigerants.
Fig. 17: Oil level glass
Oil must be charged or recharged to a level between the middle and the top of the oil level
glass.

Compressor prelubrication
Warning!
Do not start the compressor without prelubricating bearings and shaft seal.
Before starting up the compressor for the first time after a standstill period of several months,
the compressor must be prelubricated. This way the bearings will be lubricated and the oil sys-
tem filled with oil before the compressor is started. Prelubrication is carried out by connecting
an oil pump to the prelubrication branch, which is connected to the pump housing, pos. 4F, on
SMC-TSMC-HPC-HPX compressors.
