Step-by-Step Guide to Fixing a Rusted Swamp Cooler

Materials Needed

• Anode (available from cooler suppliers)
• Rust converter (aerosol or liquid form)
• Epoxy-based sealer and/or paint
• Fiberglass mat replacement materials or sheet metal for a new pan
• Wax paper
• Wire brush
• Vinegar
• Salt
• Soap
• Water

Step 1: Assess the Rust Damage

First, examine your swamp cooler for rust damage, especially in the bottom pan. Identify rust holes and areas that need attention.

Step 2: Install Anode

Place an anode in the pan to slow down future rusting. Anodes are available at cooler suppliers and serve as effective preventative measures.

Step 3: Apply Rust Converter

Spray the rust converter (aerosol or liquid) on the rusted areas of the pan. Ensure thorough coverage. If using a rust converter in liquid form, use a brush for application.

Step 4: Explore Epoxy-Based Sealers and Paint

Consider using epoxy-based sealers and/or paint for durable protection against rust. Be cautious of overspray, as epoxy is challenging to remove once it sets.

Step 5: Fiberglass Repair or New Pan Fabrication

For extensive rust damage, consider fiberglass repair or fabricating a new pan from sheet metal or rigid plastic. To prevent adhesion during repair, use wax paper.

Step 6: Check Front Screen Cover

Inspect the front screen cover for rust and scale buildup. If needed, replace the pad or distributor housing to address leaks.

Step 7: Set Up Drip Collector Pan

As a preventive measure, set up a drip collector pan with a drain outside the unit to avoid water damage. Consider using plastic pans suitable for hot water heaters or washing machines.

Step 8: Roof Coating (Optional)

Explore the possibility of using a self-adhesive roofing membrane inside the pan for additional protection. Ensure compatibility with swamp cooler materials.

Step 9: Thorough Cleaning

Take the unit outside and clean it thoroughly with soap and water. Use a wire brush to remove the remaining rust.

Step 10: Vinegar and Salt Solution

Create a solution of vinegar and salt to clean the unit further. Apply the solution and scrub the surfaces with the wire brush.

Step 11: Rinse and Return

Rinse the unit thoroughly with water to remove any cleaning solutions. Once cleaned, return the swamp cooler inside.
