How to Attach the Front Cover of an Air Handler Unit:

1. 🔌 Turn Off Power

   • Always turn off power to the unit at the breaker to avoid injury or damage.

2. 📦 Locate the Cover

   • Make sure you have the correct front panel. Most air handler covers are shaped to fit snugly and only go on one way.

3. 🧼 Inspect the Edges & Gasket

   • Check that the mounting surface is clean and that any foam gasket (if present) is intact for proper sealing.

4. 📍Align the Cover

   • Align the top edge or tabs with the corresponding slots or hooks on the unit. Many covers will have small hooks or tabs that catch first.

5. 🔩 Secure the Screws

   • Use a screwdriver to fasten the screws at the corners or along the edges. Usually 4–6 screws are used. Be careful not to overtighten — just snug enough to secure.

6. 🔍 Check for Gaps

   • Ensure the panel is flush against the unit with no visible gaps.

7. 🔛 Restore Power

   • Once everything is back in place, turn the power back on and make sure the unit operates normally.

📌 Tips:

• Check the manual — some MRCOOL or ducted units have specific clips or foam seals that need to be placed in a certain way.

• If it’s not fitting properly, don’t force it — check for wiring or tubing getting in the way.

• If the panel includes an access window or filter door, make sure that’s latched too.
