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.
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.
Yes that would be great. #1 you expect a service tech to pull out a vacuum pump at every service call? #2 what do you do with the vapor refrigerant left in the hoses when your done?
@@love2hvac Hi, what if I close the high pressure valve while system is running and then the compressor sucks in all the refrigerant from the hoses? After that I open the hp valve again. Is it a god solution?
The high side is simply the hi pressure side. In this example I used the liquid line after the condenser. It is the most commonly used and supplied high side port for most manufactures. We can use the discharge line that is also high pressure on some equipment. It's located between the compressor and the condenser. In that car we don't have to worry about the liquid, however the higher temperature of that line can burn your hand and wear out the rubber gaskets in your hose connections. Also on split system units it's usually not accessible so your more likely to see that used on package units.
@@love2hvac Thank you, so I understand this, is this the preferred method or does it matter other than the heat/gasket damage as mentioned above? Great videos. You should develop a RC troubleshooting training game like simutech did for electrical. Would be awesome.
Keep reviewing this video over and over. If you buy or are using 4 Way/Port Manifold Valve Pressure Gauges to Charge an Air Conditioner, this Video is EXCELLENT instruction on how to UNDERSTAND HOW to use it. Do your DUE DELIGENCE in taking the time to practice what He showing us.
