And yes, they are adjustable from the keypad on the front.

Something else to remember about using a VFD on a DX system, they are difficult to keep from icing up. I would recommend bypass option.

Also, if you have an open plenum you can't have wood...

Or some of that beer you mentioned in the other post Crab...... LOL

I think you can float the delta P lower than 100# if it has a balanced port expansion valve.

What tune is it humming?

Yellow Jacket.

Mello Yellow or Mt Dew?

VFD's waste a small amount of electricity internally so it would be slightly less expensive to run bypassed. I think the number is like 3%. They will run forever a 100%.

Yikes, better work on that tonight. Beer and Tequila I say!! Straight up, no lime or salt. I don't need training wheels.....LOL

Your HVAC back ground will get you into pro. Sign up.

BTW, I think Crabmaster has his feet in the sand somewhere! He is quicker than this..LOL

The latest version does work with Windows 7. The first releases didn't support Win 7 but now it does. I don't know of any issues with Inet under win 7. Could be wrong.

JJ

I think the latest is Inet 7.

I have been selling too long, my brain is mush.... :(

I love Walleye! Have fun...... :)

I was recently told to add up the sum of the FLA on all motors, not just the sum of the HP. And I think he is talking about back draft dampers in case a fan motor goes down you down have a path for...

It is mid afternoon and i am ready for a few cold ones! I am supprised this thread is still on.. might have a shot or two as well. Cheers to all.

Just remember that it is relative to the local cost of living as other guys have mentioned. Seattle is a pretty expensive place to live. Washington in general taxes our asses off! I know a union guy...

I think Hotrodrob is real accurate.

What I would say is make a list of the worst breakdown units and worst condition and start replacing them slowly or as quickly as really necessary. They have...

I wish you the best Delta. I am in Eastern WA and the paperwork is starting to make me insane. Especially the stimulus money related crap!! What a crock!! Have an awesome trip dude.

JJ

Do you mean like a generic economizer wiring diagram?

Watch out.... Crabmaster is typing!!

LOL,,,,,, JJ

I am lurking...

Since you have been to Whistler you would like lots of others in the NW. There are tons in southern BC and Alberta as well. NE WA, N Idaho and NW Montana are lousy with awesome ski resorts. I think...

Must be a foreign job!

:bump:

31K?? Can anyone say WTF??

Seriously, if they are not paying into the general fund they are not paying! Period.

It is probably also a double negative effect in that they are getting that piece of POOP Earned income tax...

We are talking about solder and money...LOL

As far as money goes with the investment topic, the last time this happened was I believe oil shortage driven. Back then we did not have a... wait for...

If you aren't buying silver as an investment yet I would recommend it highly. You can PM me if you want some information about buying. I have been buying myself for a long time. Wish I had started...

It is much more important to use nitrogen with 400 series refrigerants. We always should have been with R-22 as well but the 400 gases are more susseptable to moisture issues so haul the cylinder and...

HERE HERE!!! We miss you brother!! :cheers:

JJ

No more ryming, I mean it!

Definitely a huge loss for us HVAC geeks!! Carnak will be missed.

JJ

When you are an HVAC tech and you see a leak drain or have a service call about a leaky drain, you will not put your gauges on.

You don't have any credibility from that point forward.

JJ

I love the responses!! For her sake I hope it was more than 10 seconds! Otherwise, give her my name..... hahaha

This tread of larger companies buying their own equipment is a crock of SH**!! They are not the only ones doing it, the list goes on an on. I hope all of you charge accordingly and add more labor. If...

You said back in the beginning of the post that the discharge is an opening force for the valve.

The valve (TEV) actually works on the following;

BULB
Spring|Evap

The spring and evap...

Something to be cautious about with TEV versus cap tube, orifice or some other fixed restriction metering. If you install a TEV from the other pressure drop device you will need to add hard start if...

I have heard of blending in the WAY old days to get better oil return I think on R-502 if I remember correctly. I think they added some 22 for that purpose.

What the heck, you aren't out...

Here's my 2 cents.

I use a torque wrench every time.

I also bought some fancy connecting rod bolts for a high performance engine a while back and read the instructions on the bolt package. It...

I am sure JP can defend himself but I bet he is going to fire one over your bow based on that last comment!!

When the LP switch won't make I am sure may have heard of the delay on break bypass...

Why don't you call your "senior friend JJ" with questions like this? LOL :angel: I might be able to offer some reasons.

Later,
JJ

You know where I am.......

You know what else the wife and I discovered lately? Dole Pine, orange, bananna (or many other flavors) with Grey Goose Vodka!! It was way nice drinking!

JJ

I am in for sure! It has been a Bi### of a week! I will tip them till it no longer hurts. :couch:

Remember, normally engineers are far beyond listening to a LOWLY HVAC guy!! I have not see many instances where an engineer will take information from someone with less education than them and...

Typical server room humidity would be above 35% and below about 60%.

Best way to introduce humidity is a steam generating canister. This is the most clean way to produce steam and you can throw...

Here is a place to start, I know it is silver but he has a lot of gold friends too. www.silver-investor.com

Another thing to consider is, how low is the superheat? Copeland wants 20 at the compressor. That will also ensure that your refrigerant is not so dense that is carrying away too much oil.....

JJ

Keep duty cycle in mind as well. They are not usually rated to be at 100% load forever!! I would bet it has about a 30% load rating on it, that means it can run at full load for 30% of the time. Many...

Sounds like quality control is out the window on those parts. Are they in fact made in China? China is a huge polluter of the environment and now they are causing more refrigerant to leak I guess. ...

I have not seen it but I wouldn't say it's not possible. We are moving away from oil in the west so you just don't see it very often anymore.

With Hydro dams being everywhere around here it is...

If you are talking natural gas or propane,,, heating water, then yes. Steam or alternative fuels,, I don't think so.... I have been known to be wrong before too.

They need to be able to condense...

Be extremely careful not to get pneumaticuted!!! It is very painful. :eek2:
