General Installation Considerations:

6. Operating Instructions
The Dometic 8500 is a manual patio awning. Operation involves extending and retracting the awning using a crank handle.
6.1. Extending the Awning:
- Ensure the area around the awning is clear of obstructions.
- Locate the crank mechanism on the awning roller tube or arm.
- Insert the crank handle into the designated opening.
- Turn the crank handle clockwise to extend the awning. The fabric will unroll, and the support arms will deploy.
- Continue cranking until the awning is fully extended or reaches your desired position. Do not over-extend.
- Remove the crank handle and store it securely.
6.2. Retracting the Awning:
- Ensure the area around the awning is clear.
- Insert the crank handle into the designated opening.
- Turn the crank handle counter-clockwise to retract the awning. The fabric will roll up, and the support arms will fold.
- Continue cranking until the awning is fully retracted and secured against the RV. Ensure it is tightly rolled to prevent flapping during travel.
- Remove the crank handle and store it securely.
Important: Always retract the awning before driving your RV or during adverse weather conditions.
7. Maintenance
Regular maintenance will prolong the life and appearance of your Dometic awning.
- Cleaning Fabric: Clean the vinyl fabric regularly with mild soap and water. Use a soft brush or sponge. Rinse thoroughly and allow to air dry completely before retracting to prevent mildew.
- Cleaning Hardware: Wipe down the metal arms and components with a damp cloth to remove dirt and grime.
- Lubrication: Periodically lubricate moving parts of the arms and roller tube with a silicone-based spray lubricant to ensure smooth operation. Avoid lubricating the fabric.
- Inspection: Annually inspect the awning fabric for tears, holes, or excessive wear. Check all mounting hardware for tightness and corrosion. Replace worn or damaged parts promptly.
- Storage: If storing the RV for an extended period, ensure the awning is clean, dry, and fully retracted.
8. Troubleshooting
This section addresses common issues you might encounter with your manual patio awning.
Awning does not extend or retract smoothly:
- Check for Obstructions: Ensure no debris (leaves, branches) is caught in the roller tube or arms.
- Lubrication: Apply silicone lubricant to the moving parts of the arms and roller mechanism.
- Bent Arms: Inspect the support arms for any bends or damage that might impede movement. If damaged, professional repair or replacement is necessary.
Awning fabric sags or collects water:
- Pitch Adjustment: Some awnings allow for pitch adjustment. Consult your specific model's detailed instructions for adjusting the angle to ensure proper water runoff.
- Fabric Stretch: Over time, fabric may stretch. If sagging is severe, consider professional re-tensioning or fabric replacement.
Awning makes unusual noises during operation:
- Lubrication: Lubricate all pivot points and moving parts.
- Loose Hardware: Check all mounting bolts and screws for tightness.
If you cannot resolve an issue, contact Dometic customer support or a certified RV service technician.
