That's the only HVAC vacuum pump I've ever owned or used. Works great -
just silver solder a connection onto the suction line and there you are. I
let it suck a little refrigerant oil on occasion, but I don't think it's
necessary, because I've run my current one for many hours over many years
without trouble. Pulls a great vacuum, and free too. I'm only on my second
one in 30+ years because I threw my first one away when we moved years ago.
