PREPARING FOR
COMMISSIONING
5.1
Piping
Remove all blank flanges, stoppers, caps, and
desiccant bags before installing the piping.
Distributor piping and pipe connections must be
the correct size and designed for the operating
temperatures and pressures.
Label the compressed air and water lines
according to local requirements.
Support all piping appropriately. Pipes must not
bear any loads.
If compressed air hoses are used, they must be
of the correct size and must be suitable for the
operating pressure and temperature. Do not use
worn, damaged, or substandard hoses.
A shutoff valve should be installed in the supply
line, so that the compressor can be isolated for
maintenance purposes.
The drain line running away from the condensate
connection must be pitched at no greater than 5 /
16.4 ft m.
An air tank of sufficient volume should be installed
(as a buffer) between the compressor and the
compressed air network. As a guideline for the
tank capacity, select a size that is 10 % of the
supply volume. For example, a compressor with a
supply volume of 10m³/min / 353 ft³/min requires a
tank with a volume of 1 m³ / 35 ft³.

WARNING
Risk of injury
If incorrectly connected, the connection
can come loose and the open
connection can cause severe personal
injury.
➯
When connecting the compressor
to the compressed air network,
in addition to the operating
temperatures and pressures, the
connection flange requires special
inspection.
➯
When connecting hoses, suitable
measures must be taken to prevent
dangerous "whipping" of a free end.
Check the connection flange
The pressure connection comprises a DIN / ANSI
B16.5 flange.
The connection is indentified by a stamp on the
outside of the flange plate:
DN80, PN16 / 3" 150lbs
1
Read the connection ID.
2
Ensure that the connection and the flange
match each other.
Connect the compressor to the compressed
air network.
The compressor is fully assembled at the factory.
The connection to the compressed air network
should be made with a flexible line, that is, a
compressed air hose or compensator.
Use only hose couplings and connectors of the
correct type and size.
1
Ensure that the supply line can be connected
with no tension.
2
Connect the connection line to the compressed
air connection of the compressor.
3
Secure hose lines.
5.3
Electrical connection
NOTICE
Disturbances in the electrical supply grid
Speed-controlled
(RS)
compressor systems can
cause disturbances in low-voltage grids. For
this reason, this drive system is not intended
for use on the public low-voltage grid that feeds
residential areas.
