ASSEMBLY
1. Coat the drain valve threads with a liquid pipe thread
sealant. Install the drain valve using two wrenches -
one at the base of the PuraGuard
one on the drain valve, using a maximum final torque of
130-170 in. lbs.
2. The threaded top of the sump housing is pre-installed
into the head of the PuraGuard
that this connection is fully hand-tight before proceeding
with the installation.
3. The head cover of the PuraGuard
arrow symbol showing the direction that the air must
be supplied into the head (see Figure 1). Align the
PuraGuard
system filter correctly (the label may not
®
be facing outwards) and then insert the four bolts through
the mounting bracket holes into the PuraGuard
filter head. Tighten to approx. 15 ft. lbs.
RETROFIT: LOCATING THE PURAGUARD
SYSTEM FILTER ON THE VEHICLE
1. The PuraGuard
system filter must be mounted vertically
®
(±5° ) and must not be exposed to direct wheel splash
(located behind axle mud flap is acceptable).
2. Locate the PuraGuard
first (Supply) reservoir as possible.
(a) For vehicles with air dryers, mount the
PuraGuard
system filter upstream of the supply
®
reservoir (see Figure 3).
(b) For vehicles without air dryers, install the
PuraGuard
system filter downstream of the supply
®
reservoir (wet tank) (see Figure 4). Both the primary
and secondary reservoirs will receive their air supply
from the discharge of the PuraGuard
depending original vehicle hose arrangement, extra
fittings may be required.
3. To minimize vibration, mount the PuraGuard
filter on a frame rail. If the vehicle requires the
PuraGuard
system filter to be directly mounted to the
®
reservoir, be sure to only use a high strength nipple
fitting. (See further notes under Connecting the Air
Hoses.)
4. Do not locate the PuraGuard
producing components such as the vehicle exhaust and
provide adequate clearance from moving components
e.g. drive shaft, suspension, pitman arm, etc.
5. Locate the PuraGuard
that a minimum of 12 inches clearance horizontally (90°
minimum arc) to allow servicing. This will permit, for
example, a strap wrench to be used when replacing the
filter.
6. Be sure that there is sufficient room to attach hoses to

MOUNTING THE PURAGUARD
FILTER
®
1. After positioning the PuraGuard
to the installation requirements, mark the position of
the mounting holes on the frame rail. Note: Check the
vehicle manual before drilling a frame member.
2. Use vehicle manufacturer guidelines for mounting
hardware (use at least grade 5 hardware).
