Remove rubber bumper

The plastic shell is ultrasonically welded shut

I don't have images of the removal process but I used a razor to lightly go along the seam and then spit it apart with a spudger

Lift upwards

Lift up the battery

Use the point part of the spudger to get under the port and pry it up

Remove the PH00 screw

Use the ponty end of the spudger to lift up the airflow sensor

Use flat end of spudger to pry out chamber

Everything should now be come out of the plastic housing

Some close up images of the PCB

Pull on the heater and it should just pop out

Use the spudger to pop off the rubber lid of the chamber

Pull out the foam-like material

Use spudger to push out core
