I find that I favor my left hand when i hold my smart phone... The prolonged grip will make mine flare up! I try to use ear buds or my right hand

Anybody??? Did I use the wrong forum???

While changing a couple of schedules, I accidentally changed my schedule default to "Release".... I've re implemented the schedule ( I think I did any way) but I've Seem to have lost the ability to...

Hey Guys... Your input got me looking into the VAVs and I found one in "test" mode min damper position! I released it back to auto and it appears to be working now.
If it follows tonight setback...

Thanks for the replies guys....
In theory... nobody is supposed to touch the system and I don't show any activity in the security logs but I cant be 100% sure. In the priority array it is being...

For three years years I have had 17 AHU's on an occupied/unoccupied schedule. For some reason an Aug 02, one of the ahu's failed to go unoccupied. I've deleted/erased the schedule, there are no...

Filling in your time with "stds" ouch!

It's important to have the refrigeration system working properly as the syrup will run slower The colder it gets

You're going to want to valve off and relieve the pressure but you shouldn't have to drain the barrel
The sensor comes in direct contact with the water there is no well to speak of, they typically...

I have had success! If you follow the instructions it should work! If you look at a cross-section of the micro channel pass you get a better idea of what is going on when you braze it in a vacuum!...

The older Alco two-piece TXVs had a superheat to turn adjustment ratio! I forget the Ratio but it was something like a turn =.5 deg sh. If you were 2 deg low you would simply turn it in 4 turns and...

Don't want to sound like a parts changer but....... Ignition modules are just not a lot of money! If all of the usual checks come up with nothing, I go for the module and ignition assembly in one...

Sounds like you're working through it, just take an extra look at that oil pressure control. If memory serves me correct an OEM cuts out at six Pounds. In a pinch some guys will use a Ranco/ Penn,...

Carlisle compressors usually run a lower oil pressure if you reference it to a Copeland, 12 psid isn't out of line, Is it actually cutting out on you?

That's a sweet looking set up!

It's hard to believe that you would require a "cold trap" for this application, but try searching for some threads, I was involved in one recently. If you have one that's easily accessible it would...

No heat in master bedroom was the complaint ! Poor airflow coming from floor diffuser, lift grill and feel for damper and found humongous dildo being hidden in the boot! Husband was looking over my...

I mean no offense to my esteemed colleagues with my previous post! All of that information does come into play, Sometimes we forget how we need to be flexible in this industry. There is rarely a...

That's funny Riderman! About a week ago I tried to give a simple answer to a simple question similar to like you're asking and just got railroaded. He asked a simple superheat question that required...

just because we picked this industry doesn't mean we forfeit our summer as well! We have to nut up a little bit this time of year but at the end of the day you deserve a good quality of life and...

One of the other members recently posted a great video from YouTube as to the value of running nitrogen through While brazing! I don't recall which forum it was in, try to search it

Wow, seven calls a day! I can't remember the last time I pulled that off! I think that is an unrealistic expectation and puts a lot of undue stress on the service tech If it is expected daily! That...

Sorry boss, I did not realize I was in the AOP

Check the manufacturer Of the chillers Integrated Part load values, You may be running a lot more efficient than you think When running both machines

Above and beyond the shock value of the capacitor itself, a lot of injuries Occurr with the reaction of pulling your arm back And cutting it on something or jumping back and tripping and falling....

No, in the post you quoted of me I clearly stated that I guess I misunderstood'But for the record in my humble opinion superheat and subcooling to me are just two numbers, what you do with those...

the OP Originally asked a very simple question , Everybody is offering up opinions and charging procedures for equipment that he never asked for, All are valid and differ depending on the equipment...

I would like to see a couple of hard start kiits,filter/dryers, single and dual capacitors, some contactors and a few transformers, And a couple of the bullet style low and high pressure switches

Maybe you got me on a technicality, maybe I've been out of the residential arena for too long! I guess I don't understand how it can be calculated as it is a real-time measurement of the here and now...

The original posters question has distorted throughout the thread is a simple yes or no question as superheat is the temperature above the refrigerant saturation and subcooling is a temperature below...

York has a very specific procedure to clean the coolant side of the heat exchanger, I wouldn't have the stones to do anything less than what they specify, Having said that, a group of us combined...

I don't see where the OP clearly states it will be 60 hertz, Where is he located? What is the voltage and the cycles?

Why do some of us even bother? There's a reason why I only posted 100 times in 10 years!

As mentioned in previous posts, frequency drives are not new to chillers! When used properly they can do some amazing things I would just recommend that you consu lt with the manufacturer They may...

Please confirm if you are talking about the water side or the coolant side of the heat exchanger

I could see a room for a big pissing match between manufacturer of unit ,drive ,installation contractor, and engineer if it's not selected properly Or fails to perform in anyway. All things being...

Double check the pneumatic tubing is installed as per installation instructions, If you're showing a lot of miscellaneous sensor faults, usually it is one bad sensor or transducer Stealing voltage...

I think I read the whole thread, and hope I didn't miss anything, If you change the condensing unit and kept the original evaporator with the appropriate TX valve , All things being equal it is the...

You certainly are correct! I calibrate 0% During Winter service when the machine is static It is definitely a eureka moment when it all comes together and you actually figure out what they were...

My statement is based on two things, the level control was set up properly during commissioning 0% and 100% were actually set properly And also that there is a full charge in the machine. Sometimes...

Other than your target versus actual percent level control, the zone to zone time and percentages are set points The factory default settings for those are usually good but sometimes do need...

There, was that so hard tech Rob! Now I can look smart from the apprentice. I'll tell him 80 foot-pounds, crisscross applesauce

One of the apprentices called and asked me thought I'd be a smart ass and give him a number, Appreciate the sarcasm though

Can somebody please give me the factory torque values for the condensor water box cover on the carrier 19DG. 6564 CP, the cooling tower is at the same level

When you drop down to 1.5 ft./s in a vpf suspended solids can fall out of the chilled water in a close loop system making evaporator tubebrushing and maintenance more frequent

Does a CVHF like 65 deg tower water????? Maybe It's just growling at you a little bit!

Why do I have so much coolant left over???? Been doing alot of "Form 7" Re-assemblys on Yk's of various sizes! After draining, filling, and toping up, I am still left with 2.5 gal of...

had this problem once! the bas would shut the pump down on a sched. therefor opening flow switch and stoping chiller.. BUT>>> the flow switch was stuck closed and it would fault this code

I'll through in my 2 bits... All s/h is really doing is insuring no liquid is coming back to the comp! the lower the s/h the better the nre ( in a truly theoretical sense) true efficiency would be @...

Just got home from this exact call. spent a while troubleshooting the starter before I bumbed my head on the igv arm fully extended out ! ouch that hurt. igv works in manual, will have to...
