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

Turbo Air TSF Service Manual

is there two different sized cap tubes and this is the reason for the "sleeve?

can i get a link to the above??

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.

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

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

We typically run a new cap tube up the back wall, drill a hole through the box, and then silicone the penetration afterwards, its actually not too bad. I've done it on several True's but never on a TurboAir.

Another way without penetrating the box: Drill a hole in the suction line by the evaporator. Cut the suction line by the condensing unit. Feed the cap. tube down the suction line. Solder it all back together. New cap tube, better subcooling and no penetration through the box.

heres an update..today i went back to the case,i took a turner torch and heated up the cap tube going into the evaporator and around the sleeve...it still ran in a vacuum..so i cut the sleeve out, and psi tested the cap tube both ways..it blew clear..so i reassembled it, pulled a vacuum and recharged it..its running.
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..

Why would he pay you for the compressor when he can go buy another used freezer from auction for cheaper?

after i did the work i told the customer
to never call ME again on this pile!

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'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!

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

What about the chance of copper shavings getting into the system and causing another restriction?

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

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