## Unpacking and inspection

<Steps>
  <Step title="Prepare tools">
    Prepare a knife and scissors, and wear protective gloves.
  </Step>

  <Step title="Remove the packaging">
    Remove the wrapping film and packing belt, then the carton, and take out the air conditioner.
  </Step>

  <Step title="Check the contents">
    Check the accessory list and accessory bags in the carton and confirm the air conditioner model is correct.
  </Step>
</Steps>

<Warning>
  * After unpacking, keep the unit **upright**. Do not lay it horizontally or upside down.
  * Check carefully for damage or oil stains. If the unit shows obvious deformation or oil stains, contact the manufacturer immediately.
</Warning>

* If the product will not be installed right away or must be transported elsewhere, repack it after inspection.
* Recycling the packaging materials is recommended.

## Mechanical installation

**Tool required:** Phillips screwdriver.

<Steps>
  <Step title="Prepare the cutout">
    Choose the cutout location on the cabinet according to the drilling diagram, remove the shaded area and make the mounting hole.
  </Step>

  <Step title="Fix the unit">
    Bring the unit flange against the cabinet door and fix it firmly to the mounting surface with M5 screws.
  </Step>

  <Step title="Check the installation">
    Check that the unit is level and firmly fixed.
  </Step>
</Steps>

<Warning>
  * Check that the condensate drain path is clear and not blocked.
  * When positioning the mounting hole, make sure no internal components block the air inlet and outlet inside the cabinet. Keep a horizontal distance of **more than 150 mm** between them; otherwise return air can short-circuit and cooling becomes poor.
  * Handle the unit carefully to avoid knocks and scratches to its surface coating.
</Warning>
