Sena 33HF-OG has no service port on low pressure valve?
Update: Thank you all for the hints and for the explanations.
I was following the diagram in the manual and, tbh, a couple self described "pros' on youtube. Those sources proved to be inaccurate. I assumed the "top" was the high side and the "bottom" was the low side.
Thank you again. I will leave the post up in case someone else needs the info.
Hi all, we're a couple of DIY-er with lots of mechanical experience (welding, metalwork, computer, electronics...). This is our first Heat pump install.
Installing a Aura Mini Split (Sena-33HF-OG). I would like to hook up my manifold gauge and perform a vacuum test and leak check. However, it does not have a service port on the low side valve. How do you keep the gauges connected while running these tests without a service port?
Has anyone else seen this? Any suggestions?
