To remove fitting:
• With a firm grip hold the air hose near the fitting to prevent
recoil.
• Slide the locking collar back to release fitting. The collar will
lock into the open position when fully retracted.
• Replace the protective dust cap when finished.
This fitting is not designed to charge the air system on the motorhome.
The air supply for the auxiliary air fitting is charged from the front air tank
through a pressure protection valve. Due to the small air pressure restriction
of the pressure protection valve, maximum supply pressure is approximately
95 psi with air system on the motorhome charged to 120 psi.
The air system on the motorhome can be charged from an external
air supply source, which is located in the front electrical bay. Caution
should be used when charging the air system from this fitting. The
air supplied from an external source may contain moisture.
Compressed air introduced into the air system on the motorhome
from this fitting is not filtered by the air dryer. The auxiliary air
charge fitting will charge the front and rear air tanks. A shut-off
valve is installed to prevent air from escaping.
CAUTION: The external air supply source should be regulat-
ed to charge the air system on the motorhome no higher
than 120 psi. Damage to the air system or pneumatically
operated items may occur.
The ride height valves inflate or deflate the air bags keeping the
motorhome at proper suspension height throughout the load range. Three ride
height control valves are used on the motorhome. Two are used on the rear
drive axle, which control rear suspension height and left or right tilt of the
motorhome. Only one valve is used to control front axle suspension height.
The ride height control valves are mounted to the main frame of the
motorhome just above the axles. Each valve has a linkage rod connected the
axle. The valves make small air adjustments to the air springs while traveling.
The amount of system air used depends on the type of road surface and
driving styles.
Should it become necessary to check the suspension ride height, start with
having the air system fully charged and the suspension at a normal height.
The motorhome must be on a flat level surface.
Suspension height distance is measured from the top of the H-Frame to
the bottom of the Main Frame Rail. Specified distances may vary plus or
minus ¼”. Small offset adjustments to the rear valves may be necessary to
