Air Drains

Air system tank drains are located in the generator compartment and in
the rear engine compartment. The air tanks should be drained at least once a
month or more often in areas of high humidity and where temperature
fluctuates 40º F. or more daily.

To Drain the Tanks:

• Slowly open the drain valves as moisture will be expelled under
pressure. After all moisture and air is purged from the tanks, the
valves should remain open an additional five minutes to allow
any moisture remaining a chance to drain.
• Close valves and start engine. Check valve for leaks.
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 are set to
release at approximately 130 psi.
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 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 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.
