To remove the old filter in the supply vent (A):
- Shut down the product;
- Open the door of the enclosure;
- Locate and hold the heat exchanger (H) firmly with one hand;

To reinsert the supply vent (A):
- Clean the vent (A) with a paper towel that is moistened with isopropyl alcohol;
- Use one hand to hold the heat exchanger (H) and ensure that it lines up with the port of the supply vent (A) at the top of the enclosure;
- Use the other hand to insert the supply vent (A) into the port until it is flush with the top surface of the enclosure.

Duct
A damaged duct can be replaced by using a similar duct with a diameter of 4 in (~10.2 cm).

The following steps can be followed when changing a duct:

Shut down the product;
Loosen the nuts of the clamp of the damaged duct;
