New Micron Guage

[Texas-Tech]

A few weeks ago I purchased a new micron gauge since my Supco VG quite working right. This time I picked up a YJ 69075 and it's taught me that I really never owned a good micron gauge before now. From 760,000 to 1 scale and it's quite impressive. I have even seen how moisture is pulled through your rubber hoses but it sure does. Trying to pull down a split system with a 2" suction and 5/8 liquid line of about 140 feet. After 4 or 5 hours I'm still rising back up to 15,000 microns from a low of maybe 4000. Finally flared some 1/4 tubing and used it in place of my regular manifold and brought it all down to 455. So far I've been able to dry out 3 of these 15ton systems with one more to go. 2 pumps running together with just the 1/4 tubing on each pump, one on the high and one on the low side.

Anyone looking to purchase a good micron gauge should take a serious look at this one. Not overly expensive either.

that is one nice gauge. i want to get that one.

i have the model just below that one, the 69086, and it works great for me.

i don't use a manifold when pulling a vacuum either

All this time I thought I was doing everything the right way but now I realize just what is involved with removing moisture. Them pesky molecules just don't wanna come out of there.

Using these hoses solves that problem.

I used to own some of those Black Beauties years ago, they are pretty stout indeed. I find the solid copper works great and until the system is down I don't need the manifold, just the micron gauge.

Using these hoses solves that problem.

i use the black hoses during vacuum, but i still don't use the manifold

vacuum tree, yellow jacket makes it, and two 3/8"s hoses that have a 45° 1/4" on then end to attach to the equipment service valves (schrader port)

also i use 1/4 turn ball valve schrader core removal tool and pull system down without the schraders slowing me down any

Actually I have one of those trees, guess I'll dig it out of the garage and see If i can put it back in service. Thanks for reminding me Beachy.

I use the Y/J tree also but in transport we don't have to worry much about schrader valves. But do need a 4 valve manifold to do a 3 point evacuation.

Reeferman How do you get those Digi-Cools to stick on the wall like that ?

Is that the shower with your Digi-Cools test ?

It is laying on a floor.

Thats the micron gage I have, I love it.

YJ Tee Black line 3/8" Core Pullers and to the unit.

Thats great I'm getting one. I smashed my piece of crap supco VG that I have only owned for 6 months into a hundred little pieces today. I went to use it and all it would show was 0, new battery, 0. Supco makes crap as far as I'm concerned.
