This is the CAD drawing of the air conditioner. I don't know which is which. Who can tell me what the above part is, thank you.

From left to right, the zigzag is the filter screen, then the fan, then a section is empty, and then it looks like a surface cooler, a filter screen and a surface cooler.

Inclined is the access door (half-open state)

Water and hot water should be near the surface cooling part of the access door. The picture shows two protruding pipes.

It should be like this. The most correct thing is to read the manufacturer's instructions.
