Suction Line Inverted Loop

I recently had my split system AC unit replaced. I purchased and set the equipment myself and hired an AC technician to do the rest. In reading the instructions for the condensing unit, it calls for an inverted loop in the compressor suction line when the evaporator coil is above the condenser, which mine is. The installer did not do this, and I'm wondering how important it might be. I checked with the company that sold me the equipment and asked them if this would void my warranty. The said no, but I didn't feel that the person who told me really knew.

Thank you for your comments.

We cannot assist with DIY advice. Call your installing contractor back and ask them. What is "an iverted loop"?

I've already talked to him about it. He said he doesn't normally put them in. I assume they are to keep liquid out of the suction line to the compressor, so I was wondering if someone here could tell me.

Normally you put in an oil trap if the condenser is above the evaporator. But I've never heard of this and I've been around the block at least twice.

If you read my original post, you would know that I did not actually install this equipment.

The manufacturer did not say in their literature what the purpose of the line is, but I'm assuming it's to keep liquid from slugging the compressor. They show the trap for the type of installation you describe also. I'm not going to worry about it any more.

OMG...they didn't install an inverted loop???? We do it on every install we provide the equipment for!!! Cause we are warrantying the equipment!!! :lilhelp:

If you know how an indoor A (evap) coil is constructed, you'd realize most systems have a "built in" trap in suction line.

P.S. Actually most experienced professionals know this already......(had to add that!).

I guess the people that built it must know that too, eh? If so, why are they recommending installing another loop in the suction line outside of the coil? I never represented myself as a professional installer, so that's why I'm asking the question. As a professional, aren't you supposed to be helping people?

We don't have to help anybody, some were just being nice.
The people who sold you the equipment don't no JACK.
If I were you I would worry about the future breakdowns you are about to experience, but you might get lucky.

Here is some more helpfull info that you may allready know- Units warranties purchased online have allready been voided, of course you will find that out when you need to use it.

There is a contractor locator on this site. Call a local professional, pay their fee, and they'll "help" you. We cannot assist with DIY, and this kinda sounds like DIY to me. Toocool has already hinted at the problems heading your way with this "install" job. Go ahead and call the "company" you bought this from and demand they supply an "inverted loop" for this job. I dare you.....Aw heck, I DOUBLE DOG DARE YOU......(loved that show..)
