First Install

[selfemployed]

Told this Tech College student I'd put his first install on the web. He helped from start to finish on this heat pump to replace an old 76' Trane AC. Replaced plenum, drain line, cleaned old controls off side of furnace, set unit, new line set, replaced duct rap on part of trunk duct, sealed all connections, honeywell 8000 stat, ect. Let him start it, due temp. rise in heating, temp. drop in cooling, adjust charge, check amp. draw and check sub-cooling. All the numbers came out right in line with Mfg. specs. Since it's not proper to pay students, he ended up with several hand tools and a multi meter.

duct rap... is that like better then gangsta rap ? :)

the suction and liquid line ran though plenum, can you do that, im guessing the cooling is sitting ontop the furnace

no cap on the cleanout for the trap

looks good

[jrbenny]

That's a hand made coil box... not the plenum. :D

oh well good tin work then cheers

Why is it not proper to pay students?

[Mr supertech]

Is that old beast a belt drive lowboy

[Wheelbaron]

Looks great to me, just can't believe they would keep that old arse beast of a heater under your nice new split system. Good job getting this guy started right with pride in his work. Tell him he gots my respect:D

[ascj]

Nice job!


For the people commenting on the furnace...that is best oil furnace made. It doesn't look that old either.

I'll show him the pics today. He may be my summer help. While he is out of school for the summer I can pay him. Why ? politics (sp) He leaves during class to get field experience.

The coil is at the mastic tape above the fan control. 6" above the round style heat exchanger. Sectional type it could be less.

Jr. lets say thats a supply plenum with a coil in it feeding 2 supply trunks. But I understand what your saying.

The furnace is an 85,000 btu with a direct drive blower.

I don't put a cap on the vent after the trap. Yes I could put it upstream of the trap with a cap for adding clorox each year but since the end is right outside I'll use a wet vac and block the vent to clean out.

Why Arcoaire ? They offer a 2 ton unit matched with a 2.5 coil, Rheem doesn't. I didn't want to choke the air flow through the furnace and have to raise the blower speed to overcome it. Furnace was on high speed, now on medium low.

i hope you made a coil access on that box for cleaning

[Brian RSES CM]

The install looks good.

ThermoPride and the 13ga heat exchanger, I installed several back in the day. I was never too crazy about the cleanouts terminating behind the access panel, why not have them penetrate the panel to guaranty no soot can get in the ductwork?

I normally make a removable, 1/2" hemmed, cross broken, access cover with slotted penetrations so the coil and drain pan can be inspected and cleaned. It's a nice finishing touch on a job that says quality and pride of workmanship.

[selfemployed]

The front panel was installed after the coil was. Marked cover, drilled holes for drains and refrig. lines. Box and cover are lined too.

Thats a nice start to what looks like a promising career.

Slick job Scott !!

[Mario7]

Looks like the kid is learning how to do the job right.

[kevinf]

they make us strap the outside whips.. also that mastic tape dosent fly in texas.. must be different everywhere though

[Air Tight]

Was wondering about an access for coil cleaning also. Nice job. Looks like the basement gets some water in the winter or spring. water mark on the bricks.

[epacertified]

Nice Job
Something to start doing is strapping the sealtight under the Disconnect.
Our inspecters like that (funny thing called code)

Electrican hadn't finished his work when pic was taken. They allow mastic tape, metal tape or brush on mastic.

Glad to see you doing something.....!!:D

Had to get some help to keep me workin ;) Liz says tell you Hi.

[md-01-11376]

I like the over flow safety that is installed,I will use one on my next job. Cool.

[ernieq]

KEEP UP THE GOOD WORK. HE IS LUCKY TO HAVE A GOOD TECH TO TEACH HIM THE ROPES.

[air j]

Work looks nice and neat but why the t and open pipe after trap over furnace?

[selfemployed]

Drain line vent and place to wet vac out trap during service.

[yorktek37]

Glad to see you doing something.....!!:D

on a different note,,, I just notices your coordinates for your location. Are you located in Vega?

[sline-dawg]

A little south....Hereford..... I adjusted the gps to protect the family....:rolleyes:

[kyservice]

why do all you people put trap on upflow unit it is not needed at all

[yorktek37]

A little south....Hereford..... I adjusted the gps to protect the family....:rolleyes:

I can understand that. I guess you probably know Joel that used to work for the school's there?. Can't wait to get down that way again so I can eat at Mrs Abalos. Love their food!

[sline-dawg]

Yes sir , as a matter of fact I do..... You might try Casa Abelos....her son.... same enchiladas , but nicer place...


You must be north of here.... Dalhart..Pampa...Dumas..??? Welcome and enjoy mi amigo....:)

[yorktek37]

Ama. Tell Joel that the JCI guy said Hi. I used to work on those carrier machines up until they were removed.

I had the same oil furnace in my house when I bought it. I ripped it out and installed a heat pump, and have been saving money ever sence. I think it was only a few years old at the time.

Learn how to pipe a drain line

[nchvac]

I have to wonder about the vent after the trap as well. I have seen them before the trap to relieve the positive pressure so that the unit will drain better and not push the water out of the trap if there is too much pressure. Can you clarify this?

Also Self, I sent you a PM when you have time to check it. Thanks

I,m waitin for this !

[selfemployed]

Vent after the trap is for cleaning with a wet vac and to vent the line so there can be no double traping. If the stand pipe is up stream of the trap it has to have a cap or air will be discharged on positive pressure and water sucked back in on negitive applications ( of course). The code requires a trap on all cooling coil drains. No I don't care for them on positive pressure applications but thats the code. Location may not the best place for it, maybe off to the left side of the furnace would be better. Could not come straight down and over due to access for the fan control.

[nchvac]

"The code requires a trap on all cooling coil drains".
No doubt on the drain traps, but I don't recall the code requiring the air vent or clean out unless the manu requires it. I need to get the dust wiped off of those code books one of these days.
I must have misunderstood this concept when I was doing installation work around 2002-03. If I recall right, Trane was requiring us to put the vents before the trap to relieve the static pressure on the trap. I was thinking it was to relieve the air so that the trap would properly fill up at startup and in the first spring time run. Kind of the put your hand over the end of the drain line to stop the air and get the water flowing thing. I have seen these vents installed in this same way with and without caps. Some of them aren't that old because they have variable speed fans on them. Maybe this is a common area of confusion?
With that being said, and you knowing where I work and the high static pressures that we run, we have units running with the vent before the trap because of concrete floors or roofs limiting the depth of the trap. Without the weight of the proper column of water, the air blows the water right out of the trap. We therefore have to relieve the pressure on the trap in this way in these few cases. The loss of this small amount of air is no big deal when you are talking about 100+ tons of cooling with a minimum of 10% outside air required.

EPACERTIFIED, it is a whole lot more helpful when you leave advise or add some type of factual input on these posts.

Vent and clean-out are not required. I just do it because I'm going to be servicing it. Sounds like your units are positive pressure at the drain if they blow water out of them. You could increase the pipe size and trap to help with that (maybe). Just guessing :D

Probably can, but we are already talking about a 1 1/2 to 2" drain size. Plus, to be quite honest, they aren't that big on actually fixing problems at the school. We seem to be there to put out fires.

[woodsman]

Good to see that fan/limit control below the coil. You wouldn't believe how many I've seen above the coil.:cheers:
