Oil Trap?

This is actually something I run into fairly often. Line sets for an Ice machine condensor. How hard would it have been to cut the lines to length and pull a vacuum? This just looks second rate.

It would only take like an extra 20 minutes when installing it to make it look nice. Now its a problem child and your headache. Installer doesnt care he got paid, owner feels he got a deal since they left the extra copper. Everybodys happy.

I agree that it a sad looking mess. The even sadder part is if "Jethro" had shortened up the lines with the same eye to quality work, the machine probably wouldn't have lasted this long beacuse of the contamination, non-condensibles, copper oxides and moisture introduced into a clean system 'cause he doesn't own a vacuum pump.

Maybe it was the boss idea, had one similiar install but I actually shortened the pipe, and my ex-boss suggested that I should've never cut it and left the eccess pipe be. Too bad I've allready made it look good.

lets see 20mn more to do the job = 1/3hr x your rate of pay ($75) = $24.75
less profit for your x-boss. Is that why you dont work there anymore?

The sad part is I have seen to many Companies ( Not just Jethro's) do this type of install.
Yuma,

Perhaps not fired but quit...Talked to the boss staight out that I did not agreed with alot of his Ideas..
example: He believed that notching into a plenim for branch is better and easier than using atts. He called it ear dogging it. I called it discumbubulationing it...
By the way I tripple evac that line and working like a charm.This was at a new sonic restaurant we did all the refrigeration, heat and air work.

Yuma,

I agree and have seen it done more often this way than correctly. Manufacturers never should have started producing equipment with quick-connect pre-charged linesets. It's like a magnet for cheap, unqualified and/or lazy installers.

I learned recently that Manitowoc is getting away from the quick-connectors. Too many feild problems.

Since its on the roof most customers will never have the opportunity to view the quality workmanship they paid for.
As to why the lines were not cut to length, they are probably aeroquip lines, meaning they come charged with refrigerant. To cut them, you have to first recover the charge in the lineset. An alternative is to by aeroquip adapters, make your own set of lines, evacuate the lies BEFORE connecting them, and then tighten the aeroquip fittings.

Looks like something I've seen on the roofs of 7-11's that we were just taking care of but we lost the contract Amen

A number of ice machine manufactures that use pre-charged lines state it's OK to leave the exta lines BUT they are suppose to be inside so they won't pick up any extra heat which will be on the hot roof. And they are suppose to be laid down in a flat hoop shape.

[markwolf]

you would think that if they were going to be cheap & not cut the lineset down they would at least leave the lineset in a nice neat coil-oh well I suppose why bother trying to figure out what some dumb*ss was thinking lol!hmmmmmm I wonder if it was "two little kids mechanical service company"those guys seem to get alot of work lol!

[selfemployed]

Rolled up behind the machine or above the ceiling. It's not that hard when you want to do the job right. Scares me when I'm on a job and hear someone say ( can't see it from my house ). If you go see their house it all makes sense. Nice pic Doc.

Hey why not just set the condenser in a location on the roof where the line set will be used up in the horizontal run.

Yikes, that's just nasty...
