Rubber Seal; Torsion - Dometic A&E 8500 Series Installation Manual

DIAGNOSTIC SERVICE MANUAL
The roller tube is a 3-1/2 inch diameter tube. It has three
symmetrical grooves to retain the poly ropes of the awning
fabric.
If the fabric appears to have more than normal sag, the
roller tube deflection must be taken into consideration.
Depending on the length of the awning, the roller tube can
deflect from one to five inches with the awning in the open
position.
Installing a tension rafter will usually remove 80 per cent of
sag and roller tube deflection. All awnings 22 feet and
longer should be installed with heavy duty hardware which
includes a center tension rafter, a center supporter, and
heavy duty adjustable arm assemblies.
If the roller tube is bent, it will bounce up and down when
opening and closing the awning. On the 9000 Series this
can cause the aluminum guard to leak, because the guard
assembly may not be tight.

2.7 RUBBER SEAL

On the 9000 Series awning(see Section 2.5), an ex-
truded black rubber seal is located at the awning rail of
the coach. The seal slides into the metal hinge which
connects the aluminum guard to the awning rail. This
seal is designed to prevent water from running down the
side of the coach.
To check, inspect the full length of the seal for proper
positioning, and for cuts, tears or wrinkles. If any of
these problems are found, the seal should be repaired or
replaced.
On some units it may be necessary to silicone seal the
lips of the rubber seal to the awning rail and the top slat
of the aluminum guard as shown , to prevent water from
running down the side of the RV.

provides tension on the roller tube to roll the awning up
into the travel position.
The right hand torsion end cap contains a cam assem-
bly which prevents the awning from billowing or unroll-
ing during travel. It also allows one-person set-up of
the awning by preventing rollback.
When difficulties are experienced in rolling the awning
up, the tension on the torsion should be checked. In

most cases adding a few turns of torque to each end
will correct the problem. If all tension has been lost,
refer to the following chart and apply the specified
number of turns as indicated. This must be done with
the awning extended two feet away from the coach.
