I have never worked on anything that utilizes this particular burner, but you sparked my curiosity and appears as you probably already know that there is manual concerning how to upgrade from the...

Oh this crazy woke generation searching the web and losing their mind enough to join this site and go Karen over some 20 year old thread....LMAO....as my brother and I always say "all bitches be...

Where is Pecmsg when you need him....LOL

Thanks DAWG

For cross referencing, maybe to an Embraco, see page 4 for the compressor's specifications and then page 16 for dimensional drawings.

:munching:

Read through manual and agree manufacturer (Nortek) does not describe these terminals

Clue is in the specifications where it gives a specific number of relays, thus thinking...

I implore you to take a moment to apply for PRO membership, there is so much more in the PRIVATE area than in the public side of this site. And the Pros in that area are much more...

I sent a message to one of our members, pacnw, he just posted about a similar issue in the private PRO forum area. I am not sure if he can assist or not, but he seems to be fresh off of the exact...

Found that thread, from 2013, great read and supporting attachments.

I never paid much attention to the listed rating, that is more of a rating to tell you what to expect you are going to get new out of the box. I rely on a 10% rule on all capacitors...just me. There...

A decent FLIR may give you insight on how things are flowing when you turn that mystery stem. We have a lot of new construction for stuff going on and God forbid if anyone can pipe in a 3-way...

I am very much loving the history through photography of our trade, most especially from the early era. I for one, am in awe of the ingenuity of our forefathers and I am enjoying this journey.

Appears they were acquired originally by American Air Filter (AAF) in 1950, then AAF was acquired by Snyder General, who was then acquired by McQuay, and then Mcquay by Daikin.

We usually stay with WIKA for most of our gauges. Not saying they are the best, but seem to be the more rugged.

It was busy as hell last night and I did not get a chance to look, I will tonight.

I will look through our stuff this evening.

Happy for you buddy.

Freexicor, welcome to our site. Appreciate your input. Curious what about this thread generated enough interest for you to take the time to join and post your experience? I hope you do not become a...

Well then best head on to your local AutoZone, O'Reilys, Napa, etc. A check of their R134a supplies at random Knoxville and Tampa locations, show they have plenty cans available.

I have been using Appions for quite some time. Looking at these FP versions, I will say that I like the dual valve idea to isolate the accessory port and pretty ingenious to be able to swap from the...

I see, VirTis was a manufacturer of a Freeze-Dryer and they purchased these controllers and re-branded them with their Logo. Got it.

Learned something new, too....I always thought the 4000 series...

That Vertis controller? That controller was made by Omega, model 4002AKF...wonder if this Vertis company rebranded it? Those Omega 4002's and 4001's were bullet proof, once Omega was acquired by...

If you are just looking to program one actuator, may not be worth the cost of buying the programmer. Call your distributor and they probably will have one that either they can rent/borrow to you, or...

Here are some basic reads I found while looking into this for you.

Appears Rheem is utilizing a Sanhua JYQ series compensator, Copeland/Emerson have their version, the ACC series, etc.

Here is the patent info with description and drawings.

Figure it may be easier to find the controller itself than trying to go through True?

Is this the specific controller you are looking for?

History shows that 99% of the time new members never come back after their initial post. And 99% of the time I say this they do, so see what happens here.

Good info, but the original post was from 2011, pretty sure the guy who posted this is retired and out playing golf.

Looks like the OP is talking about a little portable process chiller maybe for a medical device, x-ray, or some laboratory process?

Here is a link to the IOM for this chiller, the Kodiak, made by...

Just a bit of information, a bit off the main subject. If you are to read up on the minimum return air temperature across a gas burning furnace (LP or Natural Gas) most major manufacturers do not...

Happy that you have the ability and aptitude to do your own work on your own home. Be careful though with performing work for other people without some form of liability insurance. God forbid there...

I have been a long-time member here and I am trying to learn how people find this site, obviously through the Googler, but more interested what about this particular thread, from 3 years ago, made...

What is the make and model?



In addition, you probably read the rules of this site that, we as members, are bound by which is that we are not allowed, no matter how bad we wish too, to assist...

Is there economization on this unit?

No.

You are over thinking all of this. UL or not UL is honestly not a huge deal.

[/QUOTE I don’t know if they used mastic too but I see a lot of tape. Since the tape is everywhere and it is sealing ductwork, can the chemicals (if any) from the tape off gas into the...

99% of residential installation companies have no clue about UL listed tape, they are not cutting corners or purposely being deceptive, they just do not know any better. Most of us in the industry...

Back when they painted the blower assembly. I was working on a Lennox G9 or maybe a G8 from this era for an old guy, his furnace was immaculate, but the blower finally gave up, he was so worried...

I agree the link was no good. I was excited to see some pics of this furnace...appreciate you taking the time to try again.

I have a few old Mars placards I pulled off of furnaces I have ripped out in the past to be replaced. Most are from the 50's. Most of the Mars units that I tore out were all considered "Low-Boy"...

On the GP1 board you have the two dip switches. You will need to figure out the accessories and options of the actual unit. You will see surrounding the dip switches abbreviations of VAV, GP, and...

Cool pic, lucky that you barely had enough side clearance!

As stated above, if all goes well, three normal days (two if burning the midnight oil), minimum three guys, and need a crane. If brave can get by with 2 guys.

I went through the top one of mine,...

I forgot to add that there are a few types of GP expansion boards, need to see exactly what you have there. GP just means, General Purpose. See page 6 section 1.1 for further explanation..
