The recomemded refrigerant pipes sizes by the manufacturer are as followings:
Liquid line 1/2"
suction line 5/8"
the refrigerant pipes which are available have diffrent liquid line 3/8"
is this a problem for the unit.? The problem i have that i can't change the piping in home.
Please advise me.

Re: Liquid line size
If it needs a 1/2 liq line and you only have a 3/8 line then your in trouble.
This tells me ur replacing the system,is the new system suitable for replacement technology,ie daikin rzq or mitsi power inverter?
Best to run new lines whatever the inconvenience,flushing the lines out can have repercussions!

Re: Liquid line size
Your right there twice Paul,
Especially the second, so many hit & runners come here expecting a quick fix & never return to answer the thread questions, which are obviously needed to help them !
Oh, well what do we do Gents ? Ignore the newbies or waste our time trying to help
Its hard not to tar all with the same brush, but the repitative actions are hard to ignore !

Re: Liquid line size
OK, I'm willing to try this again.
You mentioned one make and model of an A/C, what's the other one?
Is the toshiba model you gave the one already fitted, or the one you are looking at getting installed?
What's the other make and model you either have, or are going to fit?
Common sizes in split systems (edit: with 5/8" suction lines), are 1/4" + 5/8", or, 3/8" + 5/8"Last edited by paul_h; 03-09-2011 at 04:32 AM.

Re: Liquid line size
Hi Nike
you missed the bit that made sense mate 'hit & runners' meaning many come here 1 problem, get the info they need & never return
not that they just don't come back to give enough info to get there 1 problem resolved
