Disconnecting air con pipe at bulkhead

Hi guys, just attempting to sort my SCU out and it looks like the evaporator has to come out xD no way my hands fitting behind it. How would i go about disconnecting the air con pipes going into the bulkhead? I see a bolt between the two pipes and two smaller round looking ones on the sides
Thanks

The first thing to do is have a Vehicle A/C engineer de-gas the system. Most good companies will do that beforehand if you use them to pressure test, vacuum and re-charge after the work is complete. Cost should be around 70-90
Once the system is de-pressurised, the bolts you see in the engine bay may be removed and the Expansion Valve removed. This will free the pipes and allow the Evaporateor to be removed from beneath the dash.
You may also need to remove the Heater Matrix.
Hope that helps.

Technozen who does Pektron parts & repairs has a website, scroll down this page
to see a removal guide.
If it is not a "peg lift off" bracket you may be extremely lucky to undo the side securing screw with a cranked driver. If you do immediately buy a lottery ticket as it is your lucky day.
I had to undo & seperate the A/C unions by the bulkhead to move the evaporator inboard by a small amount and give sufficient wiggle room to skin knuckles and retrieve the SCU & bracket.
Consider mounting the repaired SCU elsewhere to simplify future access.

Thanks guys that helped a lot, the system was de-gassed already so i went ahead. Just removed the one bolt and the to pipes came straight off got it all out, soldered and back in, in just over 2 hours, not bad i think xD

Finally my rear fogs, drivers window and central locking work so happy, now i can get the air con gassed up! Next job is the exhaust (and to buy the lottery ticket!)
