2. Setup and Installation
Proper setup is crucial for the optimal performance and longevity of your Norwesco Total Drain Tank. Follow these guidelines for installation:

3. Operating Instructions
Operating the Norwesco Total Drain Tank is straightforward. Always ensure safety precautions are followed when handling liquids.
3.1. Filling the Tank

- Pour Contents: Carefully pour the desired liquid into the tank. The wide opening minimizes spills. Do not exceed the 5-gallon capacity.
- Secure the Cap: Once filling is complete, securely screw the 8" cap back onto the tank to prevent contamination and spillage.
3.2. Draining the Tank
- Prepare for Drainage: Ensure a suitable container or system is in place to receive the drained liquid from the 1-1/4" outlet.

4. Maintenance
Regular maintenance will extend the life of your Norwesco Total Drain Tank and ensure its continued performance.

- Inspection: Regularly inspect the tank for any signs of wear, cracks, or damage, particularly around the cap and outlet fitting. Although made from durable one-piece construction, external impacts can cause issues.
- Seal Check: Ensure the seal on the 8" cap is intact and free of debris to maintain a tight closure.
- Storage: When not in use, store the tank in a cool, dry place away from direct sunlight and extreme temperatures to prevent material degradation.
