Air Filtration and Regulator (FR)
A filter regulator unit, located in the systems locker on the left hand side of the body, filters the air for the

of the Operator’s Guide, it will be necessary to remove it from the locker by first draining the vehicle air
system, then disconnecting the supply pipes and releasing the fixing bolts.
