Step-by-Step Cleaning Instructions
1. Remove Debris
Use the soft-bristled brush to gently remove loose debris, leaves, and dirt from the unit’s exterior.
2. Vacuum Coils
Attach the brush attachment to the vacuum cleaner and thoroughly vacuum the condenser and evaporator coils. This removes dust and other particles that can clog the coils.
3. Clean Coils (Optional)
For heavily soiled coils, apply a mild detergent or commercial coil cleaner. Allow the solution to sit for the recommended time, then rinse thoroughly with the garden hose.
4. Rinse Exterior
Use the garden hose with a spray nozzle to rinse the unit’s exterior, including the fan blades and housing. Avoid using high-pressure water as it can damage the components.
5. Dry the Unit
Allow the unit to air dry completely before turning it back on. This prevents water damage and ensures proper operation.
6. Check and Clean Drain Line
Locate the drain line and check for any clogs or blockages. If necessary, use a wire or pipe cleaner to gently clear the line.
7. Inspect and Tighten Connections
Inspect the electrical connections and ensure they are tight and secure. Loose connections can lead to electrical hazards.
