5.2 Installation proposal
Notes:
•
All pipes should be installed stress-free to the compressor unit.
•
for more information concerning air nets, cooling systems, etc refer to the compressor installation
manual.
•
For dimensions and air flow directions refer to the AHB dimension drawings.
The dMED unit (1) must be installed on a level floor suitable for taking the weight of the dryer. There
must be a free space of 800mm around the unit.
Make sure that only clean parts come in contact with the outlet of the dMED unit. If not, this may have an
effect on the delivered air quality of the dMED unit. This is also applicable for piping and other parts that
are installed after the dMED unit.
Details about the special requirements concerning the degree of cleanliness can be found in EN7396-1
and the herein mentioned standards and regulations.
Make sure that the air delivered to the dMED unit does not exceed the limitations mentioned in this
instruction book.
2 high efficiency water separators (4) are present in the dMED unit to remove 90% of the water in the
compressed air. Each water separator is followed by inlet filters: a UD filter (5) for particle removal down
to 1micron with a maximum oil carryover of 0.1ppm).
At the outlet of each hoc unit a high efficiency PDp filter (6) is placed for the removal of particles down to
0.01
μ
m.
drain tube (8) must be installed on all water separators and inlet filters. The drain pipes to the drain
collector must not dip into the water. For draining of pure condensate water, install an oil/water
separator.
Consult Atlas Copco customer center.
The preferred and recommended installation sequence is compressor(s) (3) - vessel(s) (2) - dMED unit
(1).
The compressor intake has to be located in an area where there is minimal contamination from internal
combustion engine exhaust, vacuum systems, anaesthetic gas scavenging systems, ventilation systems
discharge and other contaminants (see EN 7396-1 for details).
Check that the correct startup procedure is followed. This procedure is described in detail in the
instruction book.
A detailed log has to be kept of when and by who service was performed.
