5. Setup and Installation

- Prepare the Connection Points: Ensure that the plumbing connection on your RV's Sani-Con Turbo system and the nozzle for the RV dump station are clean and free of debris.
- Attach the Hose to RV Plumbing: Connect one end of the 32-foot hose to the plumbing outlet of your RV's Sani-Con Turbo system. Secure it firmly using one of the provided metal clamps. Tighten the clamp sufficiently to prevent leaks, but do not overtighten.

- Inspect Connections: Before operation, visually inspect all connections to ensure they are tight and properly seated.

6. Operating Instructions
Once the hose kit is properly installed, follow your RV's Sani-Con Turbo system's operating instructions for wastewater discharge. Observe the following guidelines for optimal performance and hose longevity:
- Avoid Sharp Bends: To extend the life of the discharge hose, avoid creating sharp bends or kinks in the hose during use.
- Support the Hose: Minimize stress on the hose cuffs by supporting the hose within 2 to 5 inches of the cuff connections when in use.
- Ensure Complete Discharge: After each use, lift the hose gradually from the pump-machine connection towards the nozzle. This action helps ensure that all wastewater and residue are completely discharged from the pipe, preventing potential clogging.

7. Maintenance
Regular maintenance is crucial for the longevity and effective operation of your Drkerr 97521 Hose Kit:
- Regular Inspection: Periodically check the condition of the entire hose, including the connections and clamps. Look for any signs of damage, wear, aging, cracks, or leaks.
- Timely Replacement: If any damage or significant aging is observed, the hose kit should be replaced promptly to prevent system failures or environmental contamination.
- Cleaning: After each use, ensure the hose is thoroughly flushed to remove any remaining waste and residue. This helps prevent odors and blockages.
- Storage: When not in use, store the hose in a clean, dry place, protected from extreme temperatures and direct sunlight. The retractable nature of the hose allows for compact storage.
8. Troubleshooting
This section addresses common issues you might encounter with your Drkerr 97521 Hose Kit. For problems not listed here, please contact customer support.
8.1. Leaks at Connections
- Cause: Loose clamps or improper seating of the hose/coupler.
- Solution: Ensure clamps are securely tightened. Disconnect and re-seat the hose/coupler, then re-tighten the clamps. Inspect for any damage to the hose ends or coupler that might prevent a proper seal.
8.2. Reduced Flow or Clogging
- Cause: Incomplete drainage after previous use, or debris accumulation.
- Solution: Ensure the hose is lifted and fully drained after each use. If a blockage is suspected, carefully disconnect the hose (ensuring safety precautions are taken) and inspect for obstructions. Never attempt to clear a blockage with high pressure if the hose is connected to a macerator pump, as this could cause damage.
8.3. Hose Damage (Cracks, Punctures)
- Cause: Abrasion, sharp objects, or prolonged exposure to harsh conditions.
- Solution: A damaged hose should be replaced immediately to prevent leaks and ensure proper sanitation. Attempting to repair a damaged macerator hose is not recommended for safety and hygiene reasons.
