Commercial Split System

[young766]

Just finished installing this dude today. Everything went pretty smooth on this one. The boss was very pleased with how it turned out. This was my first 410A install. Let me know what you think.

real good work , but why no package unit?

[deaztrailnutz]

Correct me if I am wrong, but shouldn't the sight glass be installed before the drier instead of after it? Trade school has been a while.
Other than that, an excellent looking install. What brand, size of equiment was installed?

Thats what I was thinking.

[mayguy]

What that large of fresh air, I am wondering if this a make up air unit??? (I do see a new duct supposely a return?)

Other than that, a very nice job.

[Lash]

Nice work.


You don't use standing S-Slips on bigger duct?

You forgot to pound over a drive in the last pic (by the elbow on the bottom).
:D

[Jay 41]

Very nice looking job, your boss should be happy.

[young766]

This is accutally a make-up air unit. It is made by Reznor. This equipment was build specifically for the job. I didn't even think of using standing S-Lock untill you said something about it. The condensing unit is 11 or 12 tons, I can't remember. The instructions that came with the sight glass said to install them after the filter drier.

everything looks nice except for the 17ft of sealtite that runs along the ground. Sorry, i just hate the way sealtite looks when its run over 3-4ft.

still a nice job!

[young766]

I was waiting on somebody to comment on the seal tite. It looked worse than that before i tried to make it look better. The in-house sparky did the high voltage wiring. I was not very happy when i seen what he did. :mad:

[Tech Rob]

I think the piping at the condenser needs to be supported better, but other than that...

It looks like a quality install that will stand the test of time. Service technicians should be thanking you for routing the piping underneath the Air Handler.

Sight Glass goes after the drier.

[kevnew]

Square Throat Elbows are a no no

[nortonma]

I would of used a 3/8 pipe bender rather than brazing in all of those elbows, but still not a bad job overall.

[deaztrailnutz]

Sight Glass goes after the drier.
Thanks

[young766]

The liquid line is not 3/8's it is half inch

[barty]

Is the ducting insulated?

Cheers

[flange]

I assume you get snow in your area, and that leads me to the return duct. I don't really like it running along the ground like that, but otherwise I would say an above average install for sure. Hacks beware!

Square Throat Elbows are a no no

Since when?:confused:

[mayguy]

Since when?:confused:

I was wondering the same thing..

I think may have the elbows mixed up. This one has a radius elbow with a square thoat. Where a square both inside and outside corner with out a turning vane I can understand, the no no part.

I was thinking this to, looks really good though, nice job.

[manny238]

nice job on all the pipe ...duct work looks good too!.:)

[extremezr]

No yellow paint on the outdoor gas line?

[mayguy]

No yellow paint on the outdoor gas line?

Never heard of this.. I've seen it done indoors, but never outdoors.

The outside radius isnt very important it is the square throat that is the killer on elbows. An elbow with a radius throat and a squared outside corner is more efficient than this elbow with a radius corner and a square throat.

You really think so? Got proof of this?

It's not called a corner...it called a heel BTW.

[mayguy]

You really think so? Got proof of this?

I have to agree with this... How so? The air flow is going forward, and it's going to hit the outside part for the most part, than the inside.....

[extremezr]

Never heard of this.. I've seen it done indoors, but never outdoors.

Really? Up here in Canada, all piping installed outdoors must be painted. :)

[jeffe]

Nice work.. I would of used copper driers instead..

[hvac248]

Nice and clean. Paint gas line I hate rust, the only thing I would say is I try to get 1 1/2 blower dia. befor transition. :rolleyes:

[thump_rrr]

In Canada all outdoor gas line must be painted.
I don't see a regulator.
Is it 7" W.C. coming in?
How many btu is the heating section of the unit?
How many feet to the last regulator?

The gas line appears to be 3/4" or 1" at the most.

[mechanicalgsxr]

looks good it just needs a vent after the p trap and a little sealing on the duct joints

[vsba]

Nice. Sure wish more people would produce work like that.

[TAC Service]

I hope somebody else did the line and low voltage wiring.

[C&C]

Your work looks great.

The electrician sure did a hack job though. The sealtite isn't to code and they used set screw fittings on EMT. At the very least it should have been compression fittings to help keep the water out, but really should have been done in rigid. The low voltage wiring on the outside leaves something to be desired too.

[sirjames]

Nice work.. I would of used copper driers instead..

don`t think I`ve ever seen one that size before.:confused:
