I think an ice pick shoved thru the copper would be best , then shove cap tube into it

On the condenser end , cut the suction pipe in half , drill a hole through a coupler , pull cap tube thru pipe , shove through hole in coupler , put coupler in place.

All theory and sounds easy of course on paper ....

FSE_ that's a weird couple of posts. Have you done either of those things with the drill or torch before

I said drill, but what I would really do is pop a small hole in the suction with my torch

because it was the customers wish to have it replaced..

For replacement I've used a tee at either end to route the cap out of the suction instead of drill before. It was such a PITA on one of these with the tight bends in the wall it is much easier and faster to just run a new suction/cap heat exchanger up

FWIW I believe I saw a small mani ice maker that ran the cap inside the suction

Some vending machine manufacturers do that from the factory. Definitely get good sub cooling that way!

I've never imagined that, but WOW, you must be an smart old man! I like your idea, not for this specific app, but this will be of good use when time calls. I like to make that hole in the wall and run with it. Nevertheless, I like your imagination, that's what I call engineering!

Oh we've all had units gone bad and were married to until it worked right. I can think of a few
I hope I never hear about again ....

i told the customer that was a freebee..but left him the invoice for the original compressor install...im going to light some candles at a catholic church for this thing, at least until i get paid..

So they are trying to make one size fits all cabinets and bolt on specific C/U's ? ....... Good Grief

thanks icemeister..and 76olds, ill buy the unit from my customer before going through all that...

According to this:

http://www.turboairinc.com/Refrigera...sureChart.aspx

It looks like the length that runs through the box ( I believe 90.55 is the length, unable to find any info from our last battle with a TA freezer) is the same id, but the length and id before the sleeve varies depending on the compressor.

The 3 door TA freezer(tsf-72d) that gave my boss all sorts of trouble earlier in the year ended up getting a TXV and a receiver (then we found the defrost heater would intermittanty stick on due to a bad board and may have worked with changing the cap tube from the drier to the sleeve).


Now, I did not care for mounting the sensing bulb to the accumulator, and had to play with the superheat due to excessive txv hunting but,knock on wood, it has been working well.

I have been unable to find any of our notes regarding cap tube sizing or txv info due to someone "just being a little bit cranky" due to all the unbillable hours wasted on this thing.

You might be able to find the cap tube size from the "order online" section and run a new suction line/cap tube up over the top of the box into the evap area.

Good luck.

For what it's worth, here's the manual for the TSF:

Turbo Air TSF Service Manual

no, im working on a up right reach in freezer tsf-49sd/bk4f0302

i talked to a chic this am at turbo air, she said to blow it out, i laughed and asked to be connected to parts..
i listended to elevator music for 10+ minutes and hung up..

also i did change the cap tube from the filter to the "sleeve" some time ago..that part is clear, its warm, where its cool it from the sleeve foreward
to the ice ball at the evaporator..

Well shoot if it a small under counter what is the problem with changing it
I thought it was an upright where they get foamed in the whole way

I don't know about the sizing of the cap tubes, but here's that manual:
