HVAC 118 Charging with 4 port Manifold manual valve low loss fittings

A continuation form 116 and 117 now we add a 4 port manifold and demonstrate even more methods for charging. come back for 119 tomorrow, charging with probes

I was super lucky to pick up a Yellow Jacket 4v Titan manifold from a retiring HVAC technician for 60$ this weekend. Have my vac pump coming tonight, prolly order a micron gauge this week so I can start getting ready for my garage minisplit installation. Love learning about trade skills, at the same time I know how important it is to know my limits.

Outstanding instructor and 410a refrigerant charging! Won’t find a better explanation. Take the time to write down these sequence of events to follow! Thank you Ty Banaman, you 'da man on this subject.

Can’t wait to watch this when I get home from work. I always feel like if getting hands on experience because these videos are so good!

Thank you for explaining this with such detail! Very helpful for learning!

Wow, really great explanation!! You are a natural teacher, the highest compliment I think I can provide. So well done and thank you

Right on! There are so many other wrong videos on this topic.

I use a different approach to purging lines without losing any refrigerant to the atmosphere. I do it as follows. Connect the low pressure, high pressure and refrigerant tank hoses just like you did, but keep all the ball valves at the end of the hoses closed. Then attached a vaccum pump to the vacuum pump connection. Now open all the 4 ports on the manifold gauge. Remember, there will be no flow of refrigerant since all the ball valves at the end of each hose are still closed. Now run your vacuum pump. This way you just vacuumed out all the hoses as well as the manifold gauge. Now close off all the ports on the manifold gauge, starting with vacuum. From here on you can open the refrigerant and low pressure ball valves and charge as you describe. The basic difference your approach and the one I suggest is that instead of using the refrigerant to purge the hoses I simply vacuum them out.

Hi, so is the high side port after the condenser? Which port would you use if there is one after the compressor and one after the condenser?
