CHASSIS INFORMATION
DIPLOMAT 2004
The pneumatically operated items are divided into two categories: brakes
and accessory air. Brakes have full use of supplied air pressure. Accessory air
items, such as air horns, receive air through pressure protection valves
(PPV). The PPV will not allow compressed air flow until approximately 60
psi. In the event of an air system problem, the pressure protection valve will
leave a reserve air charge for braking. Pressure protection valves are installed
for safety.
The air governor, located in the engine
compartment, regulates the air compressor to
cut-in and cut-out, keeping the air system in the
specified operating range of 105 to 120 psi, then
sends an air "purge" signal to the Air Dryer.
Cut-in pressure of approximately 105 psi is
factory preset from the governor manufacturer
and is not adjustable. Cut-out pressure is
calibrated to 120 psi. When cut-out pressure is
reached, the governor will send an air purge
signal to the Air Dryer. This opens the purge
port of the Air Dryer, expelling moisture. The
purge action of the Air Dryer is identified by the
short release of air at the rear of the motorhome.
The front and rear air tanks should be manually drained
once a month, or more, depending on operating conditions
where humidity is high. Open the drain valves until all air is
purged from the tanks, allowing five extra minutes for
moisture to be expelled. Remember to close the tank
drain valves.
