PREPARATIONS FOR COMMISSIONING
5.1
Pipelines
Remove all blank flanges, plugs, caps and des-
iccant containing pouches before fitting the
pipelines.
Manifolds and pipe connections must be of the
correct size and be suitable for the operating tem-
peratures and pressures.
Label compressed air and water pipes according
to the local regulations.
Support all pipelines with correctly dimensioned
supports; pipes must not support any loads.
If compressed air hose is used, it must be cor-
rectly dimensioned and be suitable for the oper-
ating pressure and temperature. Do not use any
abraded, damaged or inferior quality hose.
A shut-off valve must be fitted in the supply line
so that the compressor can be isolated for mainte-
nance purposes.
The drain pipe leading away from the condensate
connection must not be designed to rise more than
5 m / 16.4 ft!
An air tank of sufficient volume should be installed
(as a buffer) between the compressor and the
compressed air network. As a guide, the tank ca-
pacity should equal 10 % of the delivery quantity,
e.g. a compressor with a delivery quantity of 10m³/
min / 353 ft³/min requires a tank volume of 1 m³ /
35 ft³.

WARNING
Risk of injury
If an incorrect connection is made, the
connector could come loose and the free
connection result in severe personal in-
jury.
➯
When connecting the compressor
to the compressed air network, the
connecting flange must be checked
in addition to the operating tempera-
tures and pressures.
➯
When connecting hoses, suitable
measures must be taken to prevent
the dangerous "whipping" of a loose
hose end.
Checking the connection thread

The connection label is stamped outside on the
flange plate:
Connecting the compressor to the com-
pressed air network
The compressor is completely assembled in the
factory. The connection to the compressed air net-
work must be made with a flexible line, e.g. a com-
pressed air hose or expansion joint.
Use only hose couplings and connections of the
correct type and size.
1. Ensure that the supply line can be connected
free from tension.
2. Connect the connection line to the compressed
air connection of the compressor.
3. Secure the hose lines.

Electrical connection
NOTICE
Faults in the electrical supply network
In low voltage networks, speed-controlled com-
pressor systems
(RS)
can cause faults. For this
reason, this drive system is not intended for use
in public low voltage networks that also supply
residential areas.
