Remove Protector Echo front panel or panels to expose the technology and filter
media.
Step 2 – Identify your model
Determine your model number which is a M2 (4'), M3 (5'), M4 (6'), or M5 (8'). A
decal on the front of the control module has your model on it. These numbers are
based on how many stacks of technology that you have on top of your hood from
left to right and the hood width.

 You will have 2, 3, 4, or 5 stacks for 4', 5', 6', and 8' filtered hoods.

your model M2, M3, M4, M5.
