Air System Charging (External); Air.coupler; Air Dryer - Monaco Camelot 2007 Owner's Manual

Section 10 — cHaSSiS information
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 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
fitting. 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
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 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 Coupler
Provided for convenience is a remote
air supply coupler located in the generator
compartment. This female fitting will accept
type C automotive connectors. This auxiliary
air fitting may be used to inflate tires, air
mattresses or other pneumatic items. 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.

To use this feature:
• Slide the locking collar back. Using a
firm grip, fully insert the air fitting into
the auxiliary air supply. Release the
locking collar to retain the air fitting after
the fitting is properly inserted.
To remove fitting:
• Firmly grip the air hose near the fitting to
prevent recoil.
• Slide the locking collar back to release
fitting.
NOTE
There are small air pressure restrictions
in the pressure protection valve and
tire stem valve. Due to this restriction,
the maximum amount of tire pressure
achieved when the system is used to fill a
tire is about 95 to 105 psi with air system
on the motorhome charged to 120 psi.
Maximum outlet air pressure is achieved
when the air system completes the fill
cycle indicated by the purge cycle of the

air dryer.

aIr Dryer
The air dryer, located between the frame rails
next to the transmission, removes moisture from
the compressed air system to prevent freezing
of brakes or other pneumatically operated
items. The three functions of the air dryer are
cooling, filtering and drying the system air. This
prevents valve and seal damage or wash away
of lubricants as well as freeze damage to the
system components.

Air Dryer Cycle:
The governor turns the compressor on
when the supply tank pressure drops below
cut-in pressure. Compressed air then passes
into the air dryer at the inlet port. Moisture-
laden air and contaminants pass through the
desiccant. Moisture is retained by the desiccant
and collects in the base of the dryer. When
the compressor reaches cut-out pressure
(approximately 130 psi) the purge valve opens
and the dryer purges and expels water collected
in the dryer base. The regeneration valve opens
sending a small charge of dry system air from
the front air tank back through the dryer. The
backflow dries the desiccant, preparing it for the
next cycle.
