I just got a Haier HPAC7M portable AC w/no manual. I opened it up and didn't
see where to add freon. I know each unit is different. I'm just looking for
a general idea of what to look for and where.

Once you get the required license to do that type of work, you can get the
diagram that shows you where.

Refrigeration is no longer a DIY job.

Most window and portable type units do not have service ports in
them. A licensed HVAC man can install ports so that gauges can be
used. Without gauges and knowledge there is virtually nothing for
DIY's to try beyond cleaning the coils.

The very fact you asked what you did says you do not have the
gauges or the knowledge.

This is a sealed system and is not equipted with service valves.
Process tubes are Installed in Compressor Housings during
manufacture for dehydration and charging and these are adapted
by service technicians by the addition of an access valve.
Access valves can be of various types frome line tap to a brazed
schrader access port.
Out of curiosity why do you want to add refrigerant to this Unit

You use a piercing valve on the process stub, or the suction line. I've
recharged AC for myself, and for friends. It's not dificult if you have the
EPA certificate, and some specialized tools and training.
