During installation the following points must be observed:
Prior to delivery, rotary piston machines are treated and packaged to allow for a
•
12-month storage period. If they are to remain in storage following this 12-month
period, they will need to be retreated; see storage and mothballing guidelines
TN0 1175.
Whilst the units are in storage, please ensure that they are correctly preserved,
•
packaged and, if necessary, that they undergo nitrogen replenishment in accord-
ance with TN0 1175. They must be checked every six weeks.
You must eliminate any adverse influences immediately to ensure ongoing preser
-
•
vation of the units.
Intermediate storage in dry, clean rooms that are free of vibrations.
•
The oil chambers have been sufficiently preserved for one year.
•
In the case of belt-driven machines, the V-belts should be slackened during stor-
•
age.
If the unit is to be taken out of operation for longer than six weeks, the conveying
•
chamber, piston and bright work must be preserved.
The compressor must be installed on an even foundation that does not vibrate or
•
incline.
One armature screw per machine foot/mounting hole is sufficient for this purpose.
There must be a sufficient amount of space on the installation site for mainte
-
•
nance and/or repair work. Please observe the information relating to this on the
installation drawing.
Remove all packaging material. If your machine features an acoustic hood, ensure
•
that the inlet and exhaust air louvre profiles can be accessed.
Ensure that the installation site is adequately ventilated.
•
Check that the rotary piston machine can run easily. Sluggishness indicates the
•
presence of distortion or foreign bodies.
To avoid electrostatic charging of the units, the motor, acoustic hood and base
•
frame must be earthed via the connections provided.
Fasten the piping on the discharge side and the piping on the intake side sepa-
•
rately to ensure a stable connection.
The compensator must be used for the connection to the pipeline system.
•
No forces and/or moments are permitted to act on the flange and connections.
•
Take noise protection into consideration. Piping and foundations may be stimu-
•
lated into producing natural vibrations and the associated sound emissions.
If you are planning the system in-house, the safety information, maintenance
•
information and technical documentation provided by your component suppliers
must also be observed.
The compressor unit must be carefully aligned and positioned horizontally. Opera-
•
tional safety will be affected depending on the extent of any misalignments.
Check the oil level prior to commissioning and correct if necessary.
