Installation Procedure (cont’d)
Figure 6
- Two examples of condensation trap mounting.
Step 4 - Mount the Condensation Trap
Mount the condensation trap at a location higher than the exhaust system so that excess condensation drains to
the exhaust. The condensation trap should be installed below the BPM to prevent any moisture from entering the
BPM. Make sure it is away from all moving parts and excessive heat. The flow direction will be marked by an
arrow or small triangle pointing in the direction of flow. The exhaust sample should flow from the exhaust stream
towards the BPM.
a.
Remove the condensation trap bracket from the box and use it to mark the holes
b.
Drill two mounting holes on the vehicle for the bracket
c.
Fasten the bracket to the condensation trap using the two screws provided. Make sure the outlet is
facing the correct direction.
d.
Mount the condensation trap to the vehicle using the drilled holes.
e.
Measure and cut the appropriate length of clear plastic tube
f.
Push the clear plastic tube onto the barbed fittings at the condensation trap and BPM
Step 3 - Assemble the Condensation Trap
Locate the condensation trap, 1/4” NPT to 1/4” barbed fitting, and 1/4” swage to 1/4” NPT brass fitting.
a.
Apply anti-seize compound to the NPT threads of each fitting
b.
Remove the condensation trap from the box. Be careful not to lose the two small crews in the box that
fasten the bracket to the trap.
c.
Thread the barbed fitting into the outlet marked with a square and tighten.
d.
Thread the swage fitting into the inlet marked with a triangle and tighten.
ATTENTION
The flow direction is marked on the condensation trap by an arrow or small triangle pointing in the
direction of flow. The exhaust sample should flow from the exhaust stream towards the BPM.
