Maintenance instructions
The Sabroe hand-operated oil pump, part no. 3141-155, is recommended as prelubrication
pump, see Table 14. For prelubrication: use clean fresh refrigeration oil of the same type as
the one in the compressor, and pump as follows:

The heating rod in the crankcase must be switched on for at least 6-8 hours before compressor
start-up in order to boil out any refrigerant from the compressor oil. At the same time, the suc-
tion stop valve must be open.
Check the oil level in the crankcase. The oil level must always be visible in the oil sight glass.
A hand-operated oil pump connected to the oil charging valve, pos. B, can be used for the
first as well as the following oil charges. See 3.8 Valves for operation of compressor.
Fig. 18: Hand-operated oil pump
Note: When the evaporating pressure (P
E
) is higher than 2 bar, the pressure must be relieved
before oil charging. On HPC and HPX compressors, P
E
is always higher than 2 bar.
4.13 Shaft seal
The rotating sealing surface on the mechanical shaft seal is made of a soft material, which will
tend to wear during operation. Therefore, the shaft seal must be checked regularly for tight-
ness and wear in accordance with the service intervals applying to the compressor.
