Nice job! I'm not sure about that unit, but a lot of times, you can differentiate circuits 1 and 2 by the evaporator. Stage 1 will feed the bottom, otherwise, especially with a slanted coil cold condensate from the top will hit the warmer coil without both stages running and can drip off the coil, causing water leak issues.

What is your opinion on charging a rooftop unit that has removable panels on it that are screwed to the framing that must be removed to work on the unit and to hook up guages to get a reading do you close up the panels as best as you can to get a more accurate reading or not?

When you say the system was overcharged, does that mean it had to much refrigerant?

Great job JMT. What pressure do u run nitrogen at when brazing?
@av7809
@av7809 Год назад
Very little about 5lbs psi. You can tell while you’re brazing if your braze starts bubbling out turn down the psi. Shrader core out.

Thanks for this video! But what was the main problem of such a big difference SC/SH? Clogged system and filter particularly?
@JumpermanTech
@JumpermanTech Год назад
It had too much refrigerant in it causing that high head pressure and back pressure issue. Field mistake. Whenever you open up a system it is good practice to replace the filter drier. Especially knowing that the system is having pressure issues👍

You're very welcome & thanks for watching!
@mikediamond353
@mikediamond353 11 месяцев назад
At 7:20 you say: "It took about... as much as it could take" That's how systems become overcharged. Also, right before you filled it, you say you "purged" using which method?
@ATAKace1
@ATAKace1 Год назад
I heard you have to pay a monthly subscription for some of these wireless gauge apps, is that true with the field piece ones you use? Also does the high vs low side charging and nitrogen flow make a difference with the system being off?
@JumpermanTech
@JumpermanTech Год назад
I haven't heard about any monthly subscription fees but as far as the Fieldpiece ones I'm using, it's all free. The tool itself is pricey though. Well worth it honestly. Don't think it would make a difference but I typically flow through the high side & it's natural direction being this only does cooling. Thanks for watching!
@JP-sd2cw
@JP-sd2cw Год назад
Circuit is written on the drier, also you said it was overcharged but never said how much you got out compared to what the nameplate is asking for, how you gonna know what the charge should be if you don’t know what circuit your working on?
@JumpermanTech
@JumpermanTech Год назад
I wrote that on the drier but it wasn't confirmed which circuit it actually was. I took a screenshot of the pressures the day prior and showed it in this video. It is clearly overcharged and by A LOT. The difference between circuit 1 and circuit 2 was only 8 ounces according to the plate. To be exact, use superheat, subcooling & supply/return temps if you can not find the manufacturers documents. Thanks for watching & stay tuned for new videos every week🔧⚡️

How much refrigerant did you remove from the system to see how overcharged it was
@JumpermanTech
@JumpermanTech Год назад
I didn't scale it out but I did scale it in. Look at the screenshot of the pressures the day prior. The head pressure was double of what it should have been. Once we got the charge right, we were ready to roll👍 Thanks for watching!

@gtpforever Год назад
What was the purpose of changing the filter dryer if all you were doing was recovering/evacuating the system and then adding refrigerant?
@JumpermanTech
@JumpermanTech Год назад
Anytime you open the system, you are exposing the system to air which has moisture and the filter drier must be replaced. It's just the way to do it and its good practice to do so. Some people skip out on it at times but that's just not proper. Thanks for watching!
@gtpforever
@gtpforever Год назад
@@JumpermanTech but you didn't open the system until you cut the old filter dryer out. That's why I had asked
@ramonadecoteau2680
@ramonadecoteau2680 Год назад
I wonder if they (who ever was before y’all) dumped all the refrigerant in one circuit instead of putting the refrigerant in two separate circuits. That’s why one side was overcharged and the other one had nothing.
@JumpermanTech
@JumpermanTech Год назад
It's always a mystery. You really never know. I've seen so many hacks and strange things over the years. I like to start with a clean slate. Cleaned coils & proper vacuum/charge👍

Why cut it instead of sweating off??
@mikediamond353
@mikediamond353 11 месяцев назад
When heat is applied to the dryer, it will release its trapped moisture back into the system. Cutting it off will keep that same moisture trapped in the dryer.
