Before you begin the cover removal process, it’s crucial to ensure that the mini split unit is turned off and the power is disconnected. This step is essential for your safety and to prevent any potential damage to the unit.

Disconnecting the Front Faceplate

Undoing the Hinges

  1. Locate the Hinges: The top of the mini split unit will have two hinges, one on the right and one on the left.
  2. Remove the Hinges: To remove the hinges, you’ll need to push the right hinge over and then lift it out of the hole. Repeat the same process for the left hinge.

Removing the Temperature Sensor

  1. Identify the Temperature Sensor: The temperature sensor is typically located inside the unit, near the front.
  2. Carefully Extract the Sensor: Gently pull the temperature sensor out of its position, taking care not to damage any surrounding components.

Unscrewing the Screws

  1. Locate the Screws: There are typically screws located on the front of the unit, and sometimes at the bottom as well.
  2. Remove the Screws: Using a Phillips head screwdriver, carefully remove all the screws that are securing the cover in place.

Undoing the Clips

  1. Identify the Clips: The cover is held in place by clips on the face of the unit, as well as clips at the top.
  2. Undo the Clips: Carefully release the clips, starting with the ones on the face and then the ones at the top.

Removing the Cover

  1. Lift the Cover: Once all the clips have been undone, you can now pull the cover forward and then lift it up from the top.

To reinstall the Pioneer mini split cover, simply follow the steps in reverse order. Make sure all the components are properly aligned and secured before powering on the unit.
