BENDIX SD-08-187 Manuale Utente

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

®

 system filter and

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

®

 system filter.  Check

that this connection is fully hand-tight before proceeding
with the installation.

3. The head cover of the PuraGuard

®

 system filter has an

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

®

 system

filter head.  Tighten to approx. 15 ft. lbs.

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

®

 system filter as close to the

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

®

 system filter and

depending original vehicle hose arrangement, extra
fittings may be required.

3. To minimize vibration, mount the PuraGuard

®

 system

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

®

 system filter near heat

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

®

 system filter on the vehicle so

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

the PuraGuard

®

 system filter.

7. To permit draining of collected contaminants, at least a

6 inch clearance below the PuraGuard

®

 system filter is

recommended.  Nominal clearance above is required.

1. After positioning the PuraGuard

®

 system filter according

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).
