•
Within the temperature range stated above, the intake temperature must be a
maximum of 20 K higher than the ambient temperature.
If this limitation is
•
NOT observed, the compressor housing must be heated using
appropriate additional methods.
Conversely, within the temperature limits, a warm compressor may take in cold
•
gas without any restrictions.
Alignment
Position the unit perfectly levelled, max. deviation from horizontal is 0,2 mm per
•
meter.
The motor is to be aligned and mounted according to the connecting flange on the
•
compressor.
In case the motor is already installed, the coupling alignment is to be checked
•
through the orifices on the connection flange. Afterwards the coupling guard is to
be closed properly.
ATTENTION! Secure unit against starting.
•
The alignment of compressor towards the drive must be accurate within
•
0,03 to 0,05 mm.
ATTENTION! The dimension of the alignment error affects the lifetime of the ela-
•
stic elements.
In case of initial commissioning the coupling alignment, the unit screws and the
•
lube oil pipes are to be checked again and if necessary retightened after 3 hours
working time.
