Passing Gas ... In The Motor Room...

[R12rules]

How do y'all pass gas from one rack into another .... for recovery/ isolation purposes?
And ... how do you recharge a rack or a given system when they need a hundred or two hundred pounds of freon?

I dont have a big problem with getting the gas off my truck. I now carry hundreds of pounds of refrigerant everywhere with me.

It's the part about getting the stuff up into the motor room that about kills me.

It would sure be nice if everyone who built a store did so with Icemeister's specs.
He sugested running copper from the motor room all the way down to the loading dock where your truck could pull up and recharge thru the line to the rack.

None of my stores have such a line.


Personally, I would be happy if there was simply a line that ran down from the motor room to where the landing of the ladder was.


Maybe y'all are just Hearty Men who have special back packs that carry two or three jugs of refrigerant on your back. And going up and down a ladder with 90 pounds of gas is NOT a problem for you.

That's what we have. 100' of 3/8" copper, gate valves at both ends. Just Thursday I was so glad we have those there; added 600# AZ-50. Not only does it save labor but it reduces injuries. Less than $50 of materials too.

The case R-12. Put it in at the case.

Use 100-125 pound cylinders of gas. Instead of those baby A/C cans whenever possible.

If your rack is warm, do to low gas. It will laugh at a thirty pounder.

Run a line yourself couple of rolls of 3/8 and some fittings. or buy a hose and keep it in the truck

link may mot work but ritchie sells up to 100 foot hoses

I think it's some kind of company policy to carry 30's.

I carry over 200# of 22 on the truck. But that's what most of the racks run on. We only have a couple stores in my area that use anything but 22.

This makes it simple, inventory wise.

I do like the large cylinders. Two of those on the truck would work for me.
Dont quite know HOW I would carry one of them tanks inside a shopping cart though ....


So .. what you do is simply pull the product where the TX is located, remove the shraeder core and shoot it up? Sounds like a plan.

I'll give that a try next time.

This wouldnt work though for the A/C units. They dont have any piping that runs downstairs.

Maybe for those .. I would need those hundred foot 3/8" hoses by Yellow Jacket.

hmmm ...if a 25 foot hose cost $98, I wonder how much a 100 foot hose would cost???

If you buy that 100 footer. Do yourself a favor and buy a quarter flare hand valve also. You will be glad that you did.

What did you have to give for the 3/8" 100 foot hose?

[shaun66]

charged it to company, i do all our startups and it is a company tool i need

that story worked with boss lol

I also carry a 1/4 in 50 ft charging hose. I also get the store to pull a case where possible and just gas it there.

i have one long 50 foot black hose, but the only time I used it it was more "critical" than a rack and spent a decent amount of time figuring its volume!

I guess I am lucky. either the rack room has major access, ( nice stairs), or a boom type crane, ( for comp. change outs too) or I just ROPE them on the roof!
Usually the 30's but I have roped the tall containers before and never felt unsafe.
I guess I would feel weird sending it up there from below, without being in the room, and monitoring the lines for frost, the receiver guage, etc...
