Take you injected a dye?

I take used information technology once in the 19 years I have been in the field. Seems to make more of mess than it is worth. It did work all the same.

Does anyone know of a product that takes the dye off? You lot will never know if you have a leak at your schraider because pulling yous gauge off shoots information technology all over the place.

I know it has a purpose. I accept used it one time in the 35 - 40 years its been bachelor, it did confirm a leak in a not-repairable location in a coil.

How long take you ran the organization? Information technology may accept a mean solar day or two for the leak to show. The leak could very likely be in place yous tin't come across. Like where a tube rubs on a tube support ii or iii rows in. Leak could be into a pressure activated device, seen leaks at compressor terminals; both are areas not typically looked at

I take to question why would anyone desire to utilise dye? It contaminates your service manifold (with the dye) and anything else you connect to it. You contaminate every other techs tools who comes after yous. Do you label the schrader valves that dye has been injected into the system for the side by side tech who comes forth. You tin potentially contaminate several other systems as you go, unless y'all have a set of tools simply for machines with dye in them.

I have removed the dye with Brake Cleaner, Contact Cleaner, Alcohol, Acetone before, just be carefull what yous spray the cleaner on you could finish upwardly with a worse problem if what you are spraying is not compatible and or flamable.

Practiced Luck

R22? 410?
Had someone put dye in a system once. Was leaking for years and nobody could find information technology until one twenty-four hours it was found at the Schrader. Guys kept missing it when they put the gauges on and off. I hate dye.

The spray cans of no rinse coil cleaner takes it right off. And soap and h2o will. Information technology's only colored oil.

Dye is a mess. I've plant many people use too much, and it gets all over. Leak finding can exist aggravating. Normally what I'll do is divide up the sections and make certain I don't miss annihilation.
How much is it losing at a time? What brand leak detector are you using? What refrigerant? Some leak detectors work improve on some refrigerants than others.

Define contaminate. Running refrigerant through your gauges volition clean them. NU Boom will clean it. If I can't notice a leak with bubbling or my H10in 30 minutes I add Dye.

Like where a tube rubs on a tube support ii or 3 rows in. Leak could exist into a force per unit area activated device, seen leaks at compressor terminals; both are areas not typically looked at

I have to question why would anyone want to utilize dye? It contaminates your service manifold (with the dye) and anything else y'all connect to it. You lot contaminate every other techs tools who comes after you lot. Do you label the schrader valves that dye has been injected into the arrangement for the next tech who comes along. Yous tin can potentially contaminate several other systems as you go, unless you accept a set up of tools just for machines with dye in them.

I accept removed the dye with Brake Cleaner, Contact Cleaner, Alcohol, Acetone earlier, merely be carefull what you spray the cleaner on you could end up with a worse problem if what you are spraying is not compatible and or flamable.

Good Luck

Don't utilize it on a ductless system, or kiss those eev's goodbye.

I use the yellow jacket 4-in-1 ball valve tool to inject the dye and information technology is not messy at all this style. Get-go go ride of the core removal tool and so connect the female finish of the 4-in-ane ball valve to the manifold low side, the male person connector of the valve connects to my hose and obviously the hose goes to the suction of the A/C valve, then I employ the side port of the four-in-1 valve to hook up my dye injector. Once done with the injection, circulated refrigerant from the high to depression, this washes all the dye out of your manifold and hose and so disconnect.

to the manifold low side, the male connector of the valve connects to my hose and apparently the hose goes to the suction of the A/C valve, then I use the side port of the

to claw up my dye injector. One time done with the injection, circulated refrigerant from the high to low, this washes all the dye out of your manifold and hose and then disconnect.

I like that idea. Thanks!

Practise yous accept documents backing this up?

Manufacturers service recommendations, yes. Both Diaken and Mitsubishi will not allow dye to exist used in thier systems. I will see if I can pull them up and mail service them.

are you wearing the gay looking glasses and using the OEM specific UV light? information technology makes a departure.

Truthful dat.

Yep. Dorsum when the dye kickoff came out there was a 120v overflowing light and no glasses.

Dye is actually colored oil. It should not cause a problem with whatever part.

If you bought the kit there were UV googles

My all-time tip for using dye is "dark". It seems like every time I have used it the darker I could get it in the surface area I was searching the more than pronounced the dye was in the surface area of the leak. This is hard to practise exterior in the middle of summer.

I am looking through the literature, only my filing system is a fiddling chaotic, i.e. a agglomeration of books scattered throughout my shop. I emailed daiken, when I become an reply I will share it.

Daikin does not recommend using UV Dye on the VRV systems, please apply the electronic detection device or use nitrogen to pressurize the system to assist in located the possible leak.
