5 Mounting
5.1 Assembly
The mounting position of the compressor is optional. It must be ensured that there is
no ingress of foreign matter into the connections of the compressor during assembly
(e.g. boring dust during wall mounting). Hence, the blind plugs in the connections of
the compressor should only be removed immediately before fastening the respective
connections.
5.2 Compressed air system
We recommend the use of one of our air control units for compressed air supply. The
units consist of a filter, water separator, shut-off valve, pressure controller, pressure
gauge and, where appropriate, a safety valve. If there is no maintenance unit
employed it must be ensured that the compressed air quality complies with our
specifications.
5.2.1 Compressed air quality
• Solid matter:
o Max. particle size: 5µm
o Max. particle concentration: 5mg/m³
• Dew point
o + 10°C = water content 9.4g/m³
up to +2°C = water content 5.6g/m³
5.2.2 Compressed air oiler
As a rule, a compressed air oiler is not required. All moving parts have been treated
with special grease during assembly.
The grease may become gummy when the compressor is operated for a longer
period of time with extremely dry air. It is recommended to replace the compressed
air oiler in such a case.
Caution! If the compressor has been operated with a compressed air oiler it must not
be later used without an oiler because the oil washes all grease out of the
compressor and thus prevents permanent lubrication. The remedy is re-lubrication
with MAXIMATOR grease.
If a compressed air oiler is used, the oil content of the air should be 1mg/m³ to
5mg/m³.
5.2.3 Line cross-sections
The air supply should not be dimensioned smaller than the threaded connection, a
reduction to a smaller threaded connection may result in performance losses and
malfunctions of the pump. Also excessively long supply lines may cause problems
due to the pressure drop in a small line.
