Oskab (Booster Version) - Biber OSKA9563 Instructions De Service

NOTICE
!
!
Risk of compressor damage!
Evacuate the system and flush it once or sev-
eral times with dry nitrogen, if necessary.
Mount pipelines in such a way that the compressor is
protected from flooding with oil or liquid refrigerant dur-
ing standstill. Strictly observe the instructions indicated
in the manual SH-510.
Lines for economiser (ECO) and liquid injection (LI):
The ECO connection is arranged on the top side of the
compressor housing, therefore a bridge for protection
against oil migration is not required. Guide the line hori-
zontally or downwards from the connection. See Tech-
nical Information ST-600.
When retrofitting the ECOshut-off valve:
Information
To increase the corrosion protection, it is recom-
mended to paint the ECO shut-off valve.
4.4.3

OSKAB (booster version)

An external oil pump may be necessary in systems
where a sufficient oil pressure difference cannot be
built up directly after the compressor start. This may
apply, for example, to large parallel compounding sys-
tems with extremely low condensing temperature or to
boosters.
