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 ange on the •
compressor.
In case the motor is already installed, the coupling alignment is to be checked •
through the orices on the connection ange. 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.
