Trane XL 16i 5 Ton installed yesterday

[Wabey]

I just had a Trane XL 16i 5 Ton installed yesterday, and I don't think my installer used the right vapor line size. The installation manual says to use 1-1/8 vapor line and I have what I think is a 3/4 inch line. Will this make any difference in performance, efficiency?

Should I ask him to use the correct vapor line size?

Thanks for your reply

1- 1/8 for what length of run..... 10 feet different than 60 ...

[Wabey]

I think it is probably somewhere between 10-15 feet.

Thanks for your help

I would of installed 7/8 ..you will be fine in my opinion

[Wabey]

ok. Thank you. Do you think the smaller line would compromise my new systems ability to cool the house? I paid more $ for a 16 SEER and want to be sure I get what I paid for.

Also, do you know what temperature the air coming into my house should be (about)?

Thanks - you have been very helpful.

your suction line is fine.... you should have between 15 and 18 degrees difference from return to supply.....

Your line size should be 7/8th and 3/8th

with a maximum length of 80 feet and a max vertical lift of 25 feet.

What is the document # that you read 1/1/8th for the suction?

Its in the Installer's guide (Trane) 18-AC86D1-4 for Condensing units 4TTx6.

Ok. A dumb question...how can I easily measure vapor line diameter (for a newbie)?

THanks

[carmon]

measure the o.d. of the pipe .... callipers come to mind

to answer the op question
you will lose btu output of the unit i tend to think about 3 to 4 thou but
you eff will be the same for the most part

i would recomend you have them increase the size of the lines to 1 1/8 / 3/8
so you will get the most of your unit when all of its output is needed

[Wabey]
