Installing the Air Oil
Separator Tank (AOST)
Dependent upon other installed equipment, it may be necessary to
move the AOST from its intended location. The hoses used in VMAC
compressor systems have a specific inner liner that is compatible
with VMAC compressor oil. Use of hoses other than those supplied
or recommended by VMAC may cause compressor damage and may
void the warranty.
Installing the AOST
Figure 59 — AOST installed
Front of vehicle
The AOST must be level for proper air/oil separation, and to ensure
that the oil level will display accurately in the sight glass.
Apply Loctite 242 (blue) to all fasteners (except nylon lock nuts)
unless otherwise stated.
Prior to proceeding with the AOST installation, review this chapter,
as well as the A700250 accessory instructions (included with this
kit), to determine the AOST mounting location.
Note that the A700250 accessory is not compatible with pickup
trucks or chassis cab applications equipped with a midship fuel tank.
The AOST will either mount in the “mid ship” location (A700250)
or to the passenger side frame rail behind the transmission
crossmember (Figure 59).
