Installing the air preparation pack
The air preparation pack (see the gure below) features an auto-drain to remove accumulated liquid from
the lter bowls. Once the liquid has reached the oat within each lter bowl, the liquid will be drained. The
drain ports are threaded M5 × 0.8 to facilitate connection to a suitable waste.
If the incoming air supply is grossly contaminated, a suitable pre-lter may be required to maximise the
service life of the air preparation pack.
WARNING: Before starting to install the air preparation pack, ensure that the machine is safe to work on.
Secure the air preparation pack, vertically upright, to a suitable surface using the mounting brackets. This
must be within 25 m (82.02 ft) of the NC4 unit.
NOTE: The membrane dryer features a small vent from which humid air is purged. Air can be heard
venting from this port during operation. It is essential that this port is kept unobstructed.
