Preparing for the Cleaning Process

  1. Turn off Power: Before beginning the cleaning process, ensure that the Trane mini split is turned off and disconnected from the power source. This is a crucial safety measure to prevent any accidents or electrical hazards.

  1. Remove the Front Cover: Begin by unscrewing the screws that hold the front cover of the Trane mini split in place. Carefully slide out the horizontal vanes and remove the plastic clips on the bottom to expose the Phillips-head screws. Unscrew these screws to take off the face of the unit.

  2. Lower the Drain Pan: Gently lower the drain pan and let it angle downward. Ensure that any water present in the pan is removed before proceeding.

  3. Expose the Blower Wheel: To access the blower wheel, you will need to remove the set screw and the screws along the side to move the coil out of the way. Once the coil is out of the way, you can pull the blower wheel out.

Cleaning the Blower Wheel

  1. Inspect the Blower Wheel: Carefully inspect the blower wheel for any visible dirt, debris, or mold buildup. This will help you determine the extent of cleaning required.

  2. Use a Mild, Safe Cleaner: Apply a small amount of the Refrigeration Technologies Viper EVAP+ cleaner to the blower wheel, ensuring that it covers the entire surface. This cleaner is specifically designed for HVAC systems and will effectively remove any buildup without causing damage to the components.

  3. Scrub the Blower Wheel: Using a soft-bristled brush or a clean cloth, gently scrub the blower wheel to loosen and remove any stubborn dirt or debris. Be careful not to apply too much pressure, as this could potentially damage the delicate blower wheel.

  4. Rinse the Blower Wheel: After scrubbing, use the hose to thoroughly rinse the blower wheel, ensuring that all the cleaner and debris are washed away.

  5. Dry the Blower Wheel: Allow the blower wheel to dry completely before reassembling the unit. This is crucial to prevent any moisture-related issues, such as mold growth, that could compromise the performance and lifespan of your Trane mini split.

Reassembling the Unit

  1. Insert the Blower Wheel: Once the blower wheel is completely dry, carefully insert it back into the unit, ensuring that it is properly aligned and secured in place.

  2. Reinstall the Coil: Reposition the coil and secure it with the screws you removed earlier.

  3. Reattach the Drain Pan: Carefully lift the drain pan back into its original position, making sure it is properly aligned and secured.

  4. Replace the Front Cover: Reattach the front cover of the Trane mini split, securing it with the screws you removed at the beginning of the process.

  5. Restore Power: Finally, reconnect the Trane mini split to the power source and turn it on, ensuring that it is functioning correctly.

Remember to dispose of any cleaning materials and debris properly, and always wear protective gear, such as gloves and safety glasses, during the cleaning process to ensure your safety.

By following this comprehensive guide, you can effectively clean the blower wheel on your Trane mini split, maintaining its optimal performance and extending the lifespan of your HVAC system.
