WARNING
Wear safety glasses to prevent eye injury
from expelled moisture. Open drain
valves slowly as moisture will be expelled
under high-pressure.
NOTE
Both air tanks have a pressure relief
valve which is set to release at about 130
psi.
Air Fittings
Push-in ttings are used to connect air hoses
between pneumatically operated items. Fittings,
sizes and types vary for different applications.
Threaded ttings adapt the push-in ttings to
connect pneumatically operated items. Parts
include the release ring, locking ring, solid brass
body and special rubber compound O-ring.
Damaged hoses can be repaired by splicing.
To Disconnect Hose:
Push hose into tting.
Push release ring down
against locking ring
portion of the tting
body.
While holding the
release ring down,
pull hose away from
tting.
To Connect Hose:
Push hose into tting
through the release ring and the
O-ring. Use a slight twisting motion to
seat rmly against the internal tube stop.

Pull hose away from tting to expand
and set inner seal. Ensure hose is
properly retained in tting.
NOTE
When putting air hose back into fitting,
be sure that hose is cut as squarely as
possible for an even seal in the fitting.
The cavity of the positive tubing stop
provides support to prevent leakage.
WARNING
DO NOT remove air hoses from fittings
while system is pressurized. Serious
injury may occur.
WARNING
Never place yourself under motorhome
without first properly blocking frame
(jackstands) from coming down in case
of rapid deflation of air system.
AIR SYSTEM CHARGING (EXTERNAL)

The air system on the motorhome can be
charged from an external air
supply source. Located in the
front generator compartment
is a type C automotive male
tting. Caution should be
used when charging the air
system from this tting. The
air supplied from an external
source may contain moisture. Compressed air
introduced into the air system from this tting
is not ltered by the air dryer. The auxiliary air
charge tting 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 regulated to charge the air system
on the motorhome no higher than
120 psi. Damage to the air system or
pneumatically operated items may occur.
Air System Test
Air system integrity is tested at the factory.
The air system is equipped with several safety
features. Periodically test these safety features
for function as well as checking the air system
for possible leaks.
NOTE
These tests can also be found in the
Department of Motor Vehicle (DMV) air
brake certification requirement. Some
tests will require precautions for safety
purposes.
