Hi guys I know it's an old post but as summer is going on, I still wondering what shall I do in case of a hot day with no APU nor ACU.

I remember this reference but it seems it has disappeared from FCOM a while ago, the only thing I can find now is "An external HP source may be used for air conditioning." FCOM A/C system 36-10-10.
Nevertheless it makes sense to ask if the HP external is free from contamination and certified for it, but how can you check that in real life, you just ask ground staff and believe them ?
Where I work nobody is using HP source for air conditioning purpose, could be a cultural thing as according FCOM nothing prevent you to do it.
I would be glad to here your argument and experience returns in order for me to make up my mind. Thanks a lot.
