This manual provides essential information for the safe and effective use of your Den Hartog Ace Roto-Mold SP0020-LC 20 Gallon Sumped Rectangular Applicator Tank. Please read this manual thoroughly before installation, operation, or maintenance to ensure proper handling and longevity of the product.
The SP0020-LC is a 20-gallon rectangular tank designed for various liquid containment applications. It features a sumped bottom for efficient draining, translucent walls for easy level viewing, and is constructed from medium-density polyethylene with U.V. inhibitors for durability. It comes standard with a 3/4" FNPT polypropylene fitting with a Santoprene gasket and a 5" vented lid.
2. Safety Information
Always observe the following safety precautions to prevent injury or damage to the tank:
- Ensure the tank is placed on a flat, stable, and level surface capable of supporting the full weight of the tank and its contents. A 20-gallon tank filled with water weighs approximately 160 lbs (72.5 kg) plus the tank's own weight.
- Do not exceed the tank's maximum capacity of 20 gallons.
- Verify that the liquid being stored is compatible with medium-density polyethylene and does not exceed a specific gravity of 1.7. Incompatible liquids can cause tank degradation and failure.
- Always secure the vented lid properly to prevent spills and contamination, while allowing for necessary air exchange.
- Inspect the tank and all fittings regularly for any signs of damage, cracks, or leaks. Do not use a damaged tank.
- Wear appropriate personal protective equipment (PPE) when handling or filling the tank, especially if storing hazardous liquids.
- Keep the tank away from open flames, excessive heat, and sharp objects.
- Dispose of contents and the tank itself according to local environmental regulations.

5. Operating Instructions
- Filling the Tank:
- Ensure the tank is securely positioned and all outlet fittings are closed or properly connected.
- Unscrew the 5" vented lid from the top opening.
- Carefully pour or pump the desired liquid into the tank. Do not overfill.
- Monitor the liquid level using the translucent tank walls and integrated gallon indicators.
- Once filling is complete, securely re-attach the vented lid.
- Monitoring Liquid Levels: The tank's translucent walls allow for visual inspection of the liquid level. Gallon indicators are molded into the tank surface to provide approximate volume readings.
- Draining the Tank:
- Connect a hose or appropriate plumbing to the 3/4" FNPT fitting in the sump.
- Open the valve or connection to allow the liquid to drain. The sumped design facilitates near-complete drainage.
- Ensure proper containment and disposal of the drained liquid.
6. Maintenance and Care
- Regular Cleaning: Periodically clean the interior and exterior of the tank. For interior cleaning, rinse with clean water. For stubborn residues, use a mild detergent compatible with polyethylene and the stored liquid, followed by thorough rinsing.
- Inspection: Regularly inspect the tank for any signs of wear, cracks, or damage, especially around fittings and seams. Check the lid and gasket for proper sealing. Replace any damaged components immediately.
- Gasket Maintenance: The Santoprene gasket on the fitting should be inspected for deterioration. If it appears cracked or hardened, it should be replaced to prevent leaks.
- Storage: When not in use, store the tank in a cool, dry place, away from direct sunlight and extreme temperatures. If storing outdoors, ensure the lid is securely fastened to prevent debris from entering.
