On both inlet filters a drain tube must be installed. The drain tubes (8) to the drain collector
must not dip into the water.
Install an oil/water separator to drain pure condensate water. Consult your supplier.
• A dust filter (6) (delivered with the dryer) at the dryer outlet removes particles down to 1
micron.
Should oil vapor and odors be undesirable, a carbon filter can be installed downstream the
outlet dust filter.
• It is advisable to install bypass pipes with ball valves over the filters in order to isolate the
filters during service operations without disturbing the compressed air delivery.
• It is recommended to install a ball valve (7) after the dryer. This valve should be closed at
startup to ensure pressure is built up. The valve can be left open when the pressure remains
in the dryer.
• If the maximum pressure of the compressor is higher than the design pressure of the dryer,
a full flow safety valve must be installed between the compressor and the dryer in order to
blow off the excessive pressure.
Refer to the images below for the references used.
Never overload the dryer as a too high air speed may damage the desiccant. It is
recommended to install the air dryer upstream of the air receiver to prevent overload
(e.g. after extending the dry air circuit). Consult your supplier if in doubt. See section
Operating instructions for the correct operation procedure.
Depending on whether compressor synchronization contact (connector X2 on the controller) is
used (see also section Operation), there are two possibilities for dryers equipped with the DC1
controller:
Installation in case X2 is not connected
If the freeze contact X2 is not used, the correct order of installation is compressor - air
receiver - dryer.
The entire compressed air flow from the compressor is stored in an air receiver. Only the
air that needs to be dried passes the dryer.
In case the air receiver is installed upstream the dryer and the load/unload contact of the
compressor is connected to X2, the dryer may get overloaded by the air receiver's air
volume when it is in freeze mode.
An external contact may only be connected to the X2 contact of the dryer when the
air receiver is placed downstream of the dryer.
