Hey guys I have a question for yous and a fun little picture that I drew as well !

I am going to be replacing three open/close type actuators on three dampers.
They should have been installed as...

yeah it is :grin2:

restriction right at the inlet of the strainer

okay so i can get the strainer/capillary tube together. thats great info and i dont see why the filter drier wouldnt work. if it's sized for the correct tonnage it shouldn't alter the refrigeration...

Hey guys I'm working on a fujitsu 1.5 ton system which had a restriction right before the strainer into the capillary tube. I suspected the restriction to be within the capillary tube so I cut it out...

ahhh thank you thank you gentlemen !

im sorry for any stress or stupidity/confusion that i may have caused with this thread !

i really like this stuff. it keeps your brain going and its more...

Hmmm I have a low side port and an accumulator ? But no high side anything 0.o

Sooo let's break it down. A compressor that can suck can also blow.... (just how I like em)
The compressor is...

There is no reciever in the system nor is there any high side access port or king valves to perform a pump down. The refrigerant is going somewhere though and being trapped. Its def not in the low...

I felt the discharge right at the outlet of the compressor which was cool to the touch. While the back pressure fell into a vacuum. Capillary tube restriction maybe ?

Lol thank you. +2pts

The compressor is sucking but not discharging. The discharge line does not get hot nor warm. I weighed in the appropiate charge of 4.5. There's no reason I would still read a vacuum on the low side...

ahhhhhh i give up !!! :gah:

i fire up the unit and the low side still goes into a vacuuum !
i have the correct charge for it cause the nameplate calls for 4.4 lbs up to 165ft (sais on the...

Common on the component is in series with line side of the 24V control transformer. here I drew a lil sumtin. thats how i recall it being wired but i took that component out and just wired the line...

i know what the component does i just forgot what the name of what it's called.
i googled different variotions of descriptions for that component and nada.
i remember being taught it in school and...

yeah i recovered and pulled a vacuum. im leaving it in a vacuum overnight since i didnt have time to charge. i tried being a good guy and attempted to install a service valve on the high side (3/8...

Well since I'm in work today (O/T) to do nothing but moniter temeprature I'm gonna evcaute the system and try recharging it again with the scale through the low side. I installed the access port on...

well i was there charging for a while but then i started doubting myself and kinda nervous about overcharging cause it was taking way too long. i dont have a heating blanket. i could use warm water i...

so your telling me i installed the access port on the outlet of the metering device ?! ?!?@ !?? :gah:

makes sense why its reading 0lbs....

hey guys back again and to answer the question about any strainers or filter driers, i saw none in the system.

heres a 3 part video so grab your popcorn lol

part one just an overview of the...

hey im sorry your absolutely right. i forgot that no matter how much the charge, like you said, the refrigerant pressure will correspond to the ambient temperature of the moment. so yes that...

thanks tackerdown, unfortunately the unit you supplied me with in the manual is a 410A. I'm still confused as to why the other technicians are saying that both sides are low. the line where i...

Lol sorry I'm on my phone now. Its getting late now. Ill try making a lil video or get some more information tomorrow at work. Thanks for everythings guys. Btw this unit isn't a priority since the...

Thanks tackerdown for the help. You can send any information to dmcguinness4130@live.com since idk where you sent the manuals to. The system is a/c only and the problem with it andmy original...

lol yeah i only saw one access port but it was on the low side not the high.
thought it'd give me sumtin to do just to add another port on there. its either mess with this unit or look for squeeky...

roughly 40-50ft away. i just checked online and the max distance run is around 150lbs so i am clear and it would be critically charged

well you are right but does the nameplate account for the distance of the line from the condensing unit to the evaporator ?

ahh your right ! sorry about that. ill add that information tomorrow.

and the line is the liquid line. its a 3/8 line right along the unit nearside the suction line. it goes right to the metering...

well i guess that would be a very reasonable explanation why im reading 0 lbs on the high side. i could understand the low side going into a vacuum and if i put the high side on the same line it...

the unit doesnt have a king valve i dont think? i can just put the gauges on without backseating the valve to check the pressures. i recall king valves use a box type wrench to service them. there...

the leak was at a solder joint near the compressor on the high side. i did a quick braze and it was good which tested with nitrogen overnight at 90lbs. i released the nitrogen the next day (today)...

ive recharged a 5 ton split system on site before with no problems. this one is just doing sumtin i havnt encountered before. like as if there's a restriction on the high side or sumtin

hey no worries i did purge the system out with nitrogen a few times and took the schrader out on one port so whatever crap is in there could flow right out.

and its a fujitsu model - ASU24C1...

haha well to be honest i would love another tech on site since i am the only one at the moment. i have to take care of 35 air handlers, 4 package units, 2 boilers, 2 absorbers, and about 10 split...

no i didnt weigh the charge in. in this season im assuming the back pressure should be charged lower than 65lbs. its quite chilly still over here

thanks for the reply ! and yes the ball valves are open on the hoses and the unit does not use king valves. this split system is a/c only. it cools a projection room year round. im assuming that even...

hey guys i'm new to the field and this is my second time ever having to charge a split-system at work. The unit is a 2 ton fujitsu R-22 split system.
it had a leak which i located and repaired, i...

all the piping is right there from the chiller since the condenser is cooled by the chilled water. All I would need to do is stop the supply line from the chiller and just put in the new coil. The...

Hey guys I have a lil project that I may be working on soon. We have a water-cooled R-22 system. The water for the condenser used to come from the hudson river but it was changed yrs back to bring in...

thats a good thing !
at least he knows i really do care bout the job and im trying to learn.
im motivated and i like this stuff !


thanks alot guys for the information ! i was really nervous to...

hey it is a 16JB and thanks I just added mine on my profile as well.
any kinda information to read up on would be valuable

i just found this as well

http://www.faateng.com/pdf/16JB_PD.pdf

hey your right thats exactly it !

all i found was this info

http://www.arvandcorp.com/userfiles/file/Carrier_fa.pdf

its in another language tho :confused:

yeah their main cooling comes from the 2 chillers that they have. 1 runs on a certain time schedule and when that one shuts off, chiller 2 comes on. the main deck underneath the flight deck has about...

nothing but a good ol' fieldpiece meter and a bag with a couple of hand tools and guages.

I will definitly report back tomorrow aftenoon on the model of both chillers.
at this moment i dont know...

haha I was totally honest with everything I said to the man. He knows I'm just comming out of school and I told him I had no field experience but that I'm willing to learn and am motivated to work in...

hmmm maybe not 500 tons but I'ma take my guess at no more than 300tons for the whole ship, I asked the guy myself what he had if it was an absorption system and what tonnage it was and he just kinda...

wellllllllllll the head of the maintenance team stated, "this is a one man gig, I dont have time to come down here to fix sumtin when its supposed to be your job or else you'll be thrown out like the...

Thanks alot you guys for all of the replies!

[QUOTE=GoColts;10354922]I still have alot too learn, but I do ALOT of reading on my own time Google is a very powerful tool [\QUOTE]

i think im going out drinking tonight to get this off my mind aha :cheers:
but thank you! I'm just gonna have to rack up on the awefully good salary that I wasn't expecting and then get fired......

So okay I just graduated from school two weeks ago and I happened to land a job at the Intrepid Museum in Manhattan. I threw my application there because I thought whats the worse that could...

i see nothing wrong with the curriculum to be honest. maybe test wise they should incorporate all segments into the tests up to that class that your in but nothing so far has dissapointed me. I was...
