Brake Back Pressure - BD X-MONITOR Installation Manual

6 November 2006 1085200/5210/5220 Dodge X-Monitor 12

Brake Back Pressure

On the BD Exhaust Brake valve there is a 1/8" NPT plug used for measuring brake
back pressure. Remove this plug and install the tube fitting with 1/8" NPT male
threads. One end of the formed piece of stainless tube has a fitting attached and
other end is bare - Insert the bare end into the fitting on the brake valve.
Secure the stainless tube to one of the manifold studs using the supplied hardware
in the brake pressure kit. Connect the plastic tubing to the fitting on the end of the
stainless tube, run it into the cab and connect it to the filter attached to the RPS
module.
Connect the RPS module to the X-Monitor module as per diagrams and secure all
wires and tubing, keeping them away from heated or moving components.
The plastic filter housing will need to be changed out after 6-12 months of use.
The replacement time is dependant on air humidity and the amount of moisture that
is trapped in the actual filter. The replacement filter part # is 1800135. This filter
should be mounted in a visible, easy to access location.
Because of the moisture accumulating in the line and filter, it is highly recommended
that the RPS unit be mounted at the highest point of the air line causing all the
moisture to run back down the line into the exhaust.
