I’ve searched and have failed to find a definitive answer, what is the safe operating temperature to run the Anycubic Photon?

I have a storage unit on the outside of my apartment that has nothing in it, was considering setting up shop in there. Living in Northern California means hot summers, and the room gets up to 38C.

The other alternative is building an enclosure that vents through the sliding door. (Much more work)

What do you guys think?
