Can I connect the bottle for charging to the "red port" on the manifold, instead to the "yellow port"? Because I`ve a mini-split and the "red port" is free. I would like to use the "yellow port" only for recovering refrigerant. I have 2 knobs on my bottle, for liquid and gas. This means I wouldt have to change any hoses. Or is there something against doing it this way? Could the SMAN be damaged as a result?
I'd be a liar to say i never used my gauges to pull a vacuum. Thats just how everyone back in the days did it. No micron gauge, no core tools, no large hoses....no cares in the world....we used to use a 2 smoke vacuum....after 2 cigarettes....vacuum was done. Hahahaha. Thankfully it was R22 equipment and is very forgiving of careless install mistakes....410 is not as forgiving. I have since obviously changed my methods of vacuum. Things were simpler back in the days. Started this trade back in 99
I was lucky to get to work with some commercial guys back in the day that where big on Deep vacuum. thus by analog micron gauge. But yes I too would be lying if I said I never cut corners or was in hurry.
A little different than hanging the gauges for 30 minutes to see if the needle moved. Thanks again for the videos. 🥃🥃🍺🍺🍺🏌🏻♀️🎯 Stay safe. Retired (werk'n)keyboard super tech. Wear your safety glasses!
Ball valves are preferred for all manifolds. They provide full flow They are not restrictive They rarely fail They provide more control They are not as affected by contaminants first and debrise.
My job usually does a 10 min decay test if it doesn’t go above a 1000
Thank you so much Mr.Ty keep going you’re in the head of teaching.🌹
2.5 hrs to pull that vac?
How long is that line set?
What cfm is the pump rated to?
Was the pump oil contaminated?

would you clean an oil gauge set and hoses with isopropyl. field piece says you can clean all but the vacuum port with it.
How many pounds of freon we should put while the system is off?
thanks, always good Ty
👍👍

why not charge through the suction after deep vacum?
Liquid will collect in the suction line, when the compressor starts, it will flood it and cause damage.
@@love2hvac so after every vacum you charge it back up through the liquid when its off?
@@love2hvac when should you charge through the suction
Yes especially after vacuum.

I haven't used the 4 port for vacuum in years. I was surprised at how long it took!
What is hvav
😂 one of my endless spelling and keystroke errors! Thank you for the heads up!
Why are ball valves generally preferred when using a 4 port manifold?
Ball valves are preferred for all manifolds.
They provide full flow
They are not restrictive
They rarely fail
They provide more control
They are not as affected by contaminants first and debrise.
@@love2hvac Thats good to know. Thanks for the speedy reply!
