I have an old Airflow unit from 1996 that has a Dataguard 4.0 microprocessor on it. Have not seen a Airflow unit in years. Looking to see if anyone knows or remembers the passcodes? I used to use the...

Got a 06ET299360 in a Carrier 38AKS044---500 that I ran a call for the compressor going off on loss of oil. The AHU is built up so not a Carrier. There was no oil level in the compressor sight glass....
The company I work for is doing similar job right now. It is a data center with 20 year old Carrier RTU's. They wanted to replace their aging equipment and reduce the risk of water leaks/condensate...
I do not think Dakin will be going out of business anytime soon. They are the 2nd biggest manf of HVAC equipment, only outdone by Carrier. They were huge in Europe, Asia, and Australia etc. then not...
In my area, distributors are already getting away from stocking/selling R22 equipment. Have been since before the beginning of summer. According to the EPA's clean air act, after Jan 1, 2010, R22...
The "A" circuit only has one compressor. When I had all the heads off I looked at all of the plates very carefully and the all looked good. Pushed on the pistons to see if they would move freely but...
Was getting ready to head out to the site Monday mid-morning (had to switch out my cell phone, company changed cell phone carriers) to do some more investigating of the compressor and called the...
I am looking for any help I can get at this point. I was failing on oil when the relief was opening. But I already replaced the relief and have a new problem. Running the low head and high suction,...
It is suction cut off and only one head unloads. I have thought about unwiring the solenoid valve to see if it would stay running loaded all the time. The new problem has only arose since I replaced...
Hoping someone here can help me or give me a direction to go in or what to look at cause I am stumped.
The 06ET is compressor is the A1 on a Carrier model # 30GT050 air cooled chiller. I am the...
I think I can help you, I am always dealing with raising low concentrations and having to figure out how much pure to add to get the concentration to where it is supposed to be. Is your current loop...

I was trying more to see if someone could come up with a good reason or knew why engineers spec expansion tanks to be at the highest point in the system. I have seen this on more then one set of...
An old Carrier air cooled chiller, 30 ton
I have a question I am hoping those of you with vast more knowledge then myself can help with. I was having a discussion with my boss about the proper location of an expansion tank in a glycol...
Yeah, the unit I need one for is a small 1 1/2 ton water source heat pump for a conference room.
Thanks for the info. I talked to Metrex yesterday and they gave me the info on one they make...
I know I have seen head pressure water regualting valves on small water source heat pumps that modulate water flow thru the water coil to maintain head pressure during cooliing operation and when in...
Honestly I am not sure. The company I work for was putting in a 36 RTU's (can not remember the size now but they were big, had 50hp blower motors) and they had MircoTech II controllers in them (had...
Call McQuay at 763-553-5462 and ask for their technical support department. Better yet I would ask to talk to Paul Hollingsworth.
The company I work for belongs to the Unified Group. I have attended several of their seminars over the last two years. What did you want to know about them?
There are really only two ways to charge an a/c system thru the high side. First is if you have pulled a unit into a vacuum because of a repair or new install or something. If the unit is in a...
Alot of companies in my area already have them. I have heard good and bad about it. I have mixed emotions about it myself. The VP of the company came to me and asked me to price up systems. I can see...
Try renting a electric stair climber. Looks like a hand truck but it climbs the stairs with minimal effort using an electric slider mounted on the back of it to lift the load to the next step instead...
Trying to figure out why I came out of the field to be the service manager. Still have not figured it out.
This was suppose to be a replay to another post where a guy asked if you were allowed to take anything in when you take the test but I hit new topic by mistake. Not all my guys passed on the first...
I am a service manager of a company and have sent 20 techs through. None were allowed to take anything in with them except maybe a pencil.
Upgrades and additions to the Maxwell system can cost anywhere from $5000 to $10,000 depending on what you want. And if you want something custom think higher $$$
Stay away from a program for accounting and dispatching called Maxwell. The general program is limited and does not provide much and if you want the program to do more it will cost big bucks. If you...
Used it in a piece of lab equipment that had R12 in it. This high vacuum chamber needed to be held at -10F and the Hotshot worked well.
Glad to hear it. Just make sure that since the company is moving you up that you get the rest of the guys on board with you recovery. Congradulations again.
Did not dream up the company ripping people off. All I can say is at the company I work for we, pass the charge along for refrigerant disposal. Maybe they don't, but if they charge the customer for...
I am not trying to bash anyone but telling some one "if you can not go with the low of the place" just to leave the job and not turn them in for violating the law is the WRONG attitude. I guess there...
Best of luck.

In you first post I took your attitude as "been there, done that". I know you said the mistkes you make are from never running across the problem before and basically makeing a best guess...
Are you sure in of the EXV are bad and not just a sensor. I have seen one to many replaced just to find out that it still did not work and that a sensor was bad. The pc bord takes readings from two...
I have never seen or heard of a ladder crane. I hate when I have to send a helper or an apprentice with a tech to pull a 3 to 5 ton compressor up on a roof. I know how hard it is. Used to do it all...
Scrapper,
I used to have a guy thay worked for me that had the same attitude you do. I am not trying to be rude by real world truth is you should not be in a van and out on your own after 10...
I would not spend my hard earned money to buy a recover machine to work on their equipment. That is an excellant attitude that you want to do things the right way. If you keep that attitude and don't...
Unless the unit was purchased with a phase monitor or one was installed in the unit when the unit was installed then no there is no type of protection. The compressors will go off on internal...
I would find a new job. If they do not want to follow the guidelines set forth by the EPA what else are they doing that is agaist the law or not up to code. You can be fined and/or go to jail and...
I have been a service tech for the last 16 years, the last 9 with the same company. All my co-workers and myself had complained about the service manager since he was hired, about 5 years ago. Word...
Penny,
I would ask to see a compressor tear down report on the compressors that were installed and failed. In order for the compressor re-manufacturer to give your contractor a credit on the failed...
If this is a package unit and not a split, on a Liebert that old, a high pressure switch trip also locks out the entire unit. Also check to make sure the condensate drain is not double trapped. Not...
