Ed,
I'd be surprised if 12 psi will hold the door seal under a pressurized
cockpit. My experience was that it tended to "lift away" from the door frame
at lower pressures, allowing an air gap that limited the differential I
could maintain. I still haven't verified that I'm getting the full 5.5 PSI
differential the system is supposed to produce. ...really need to get that
big jack hammer compressor hooked up to my snout to test it all out...

Subject: [LML] Door Seal Test

Hi Jeff,

Got the pictures for you on the door seal test, which we are attaching for
your perusal.

Be sure you test the seal with the door closed and latched!  I left our door
open so you could see how things were hooked up.  The adjustment screw for
adjusting the pressure is located on the pressure switch between the two
terminals.  It will take a flat blade screwdriver to adjust the setting.

Our switch was preset at close to 20 psi and we lowered it down to 12 psi.
We haven't pressurized our plane yet, so I can't determine if that pressure
will seal the door.

Good luck,

Ed Smith
