As JayGuy said collect vibration data to see whats going on.:grin2:

:ditto:
Very seldom can you run a centrifugal machine very far from factory design parameters

Pulling a vacuum on a drum while draininig oil out of chiller into the drum is one way to do it, but is more time consuming

Maybe missing something here, but I always use a small gear pump to remove the oil & put it back in on low pressure machines, never pressurized system just to remove oil. Just be sure you turn off...

You told that right:eek:

:ditto:

Are you sure you said what you meant to say?? If so please explain to me what takes place as far as contactor sequencing in the wye configeration to start chiller.

The installation manual comes with the new seal on the ones I have done.

I have never seen a chart, but called Pueblo once when I had some odd megger readings on a similiar machine, & was told I was o.k. to start compressor as long as I was above 1 megohm. Do you have any...

We send all of our Carrier rotors, wheels, & etc. to Carrier in Houston, TX to be repaired or a new part fabricated.

Check Valve it is.:bsing:

As you said, what you are hearing is probably gas flow noise, it takes a second or two for the disharge check valve to close and stop that gas flow.

Thanks for all of the replies.:CU:

WHAT IF??? We just used air cooled equipment:LOL:

I was wondering if there was a good rule of thumb on much revenue a tech should produce in say a year. I understand this is probally not the best forum to post this question in, but was interested in...

Dry Run, if I understand your question correctly, is used to troubleshoot starter components with high voltage de-energized & 115 volt test power connected.

If you dont mind me asking what kind of process is this chiller used for?

We use a dry ice tote & a 1000lb. recovery cylinder with a short dip tube when pulling vacuum to eliminate moisture from getting to vac. pump, but never thought of pumping liquid refrigerant through...

Thanks for the reply but, I already have a redi controls oam pot, this moisture must be removed while machine is offline due to cold operating temps 5-10*F leaving subcooler & -30*F or so evap. temp.

Suction pressure runs about 10"-15" vac., water cooled oil coolers, & water cooled condenser which will all be checked out during repairs.

I will be changing the oil as well, all 15 gallons.

We get parts all the time from Syracuse, we dont have a whole lot of trouble with back orders, they are very proud of their parts though.:yes:

I am going to be making repairs on an open-drive process cenrtifugal machine, & need to dry the refrigerant out, per refrigerant analysis, while making repairs. I will recover about 12,000lbs. of...

I have replaced pumps, motors, & float switches five or six times over the years. I have an account with 4-17S30 & 1-17MA40 Carriers. We removed the internal micro switch & toilet bowl float &...

If Carrier has the parts I can get them for you, (email in profile)if you cant find any other alternatives. We get 17 series parts from Carrier.

I just use a ball pein & a blunt/dull chisel to loosen or tighten.

Like yourself I prefer troubleshooting over teardowns, but overhauls haven't got old yet. It does seem like everytime I turn around here lately they have sold another overhaul. Whatever pays the...

What about renting the hose & victalic couplings from Trane Chiller Source, just pass the cost on to the customer then you are not stuck with the hose at the end of the job. Just an idea.

As you know the info on carrier.com is only iom's, I was looking for some kind of step by step detailed teardown guide for the newer guys coming in, as is it is my responsibility to bring everyone up...

I was wondering if anyone was willing to share any literature on 17S30 or 17MA40 Carrier compressors. I have all the literature from carrier.com. I also have quite a bit of on-the-job experience...

I have an account that has 2 RTHDs that need the modulating cond. water valves. I completely forgot all about them. Thanks for the reminder, I think I'll turn in a tech lead.:)

TRANE!!!

Trane is the only way to go.:payattention:

If you were talking to me, no I do not have any 19DH literature. Try carrier.com more than likely the literature is there just tough to find on thier site sometimes.

Just wanted to say thanks for everyone's input. I told the customer about changing dip switch on ccp1 to disable ground fault, they changed compressor has running fine for three days now. We are...

Been trying to send email for 20 minutes now, my outlook is not working.

The shaft shoulder measurement has everything to do with the contact seal. In other words thats the main reason for this measurment.

Just wondering, have there been any seal problems with the machine. The email is on the way, sorry its taking so long to get back to you, these 12-14hr. days are begining to wear on me.

There is a spacer on the thrust end that can be machined to get your shaft shoulder to casing measurment correct. Did you have to replace the rotor assembley, if so your new rotor is probably a...

Hey ChillerWisperer did your quote/signature come from Dave at LaCrosse?

I have qite a bit of literature, all from carrier.com which you probably already have. If you have any questions I could probably help. I have done 2 17ma40 rebuilds & probably 10-15 17s30 rebuilds...

Thank you kind sir.:D I had the literature already just didn't see the note about the dip switch setting. I must of had my head up my butt. Thanks Again

[QUOTE=thegoodlistener;3859022]The info to disable the ground fault is in the literature , I honestly have never had to do it.

I could not find anything on disabling the ground fault in the...

The literature says "detected current to ground 2.5 amps +/- 2 amps" = ground fault alarm.

[QUOTE=thegoodlistener;3859022]The info to disable the ground fault is in the literature , I honestly have never had to do it.

I will read up on that thanks for the info. If you think of anything...

Thanks for the info, and yes I megged motor all six leads to ground and all leads to each other just to be sure.

No I have not, I was not aware I could do that. Do you happen to have any literature on the chiller. I downloaded what I could off of the carrier site.

The version 26 board is for the compressor that is tripping.

Chiller#2 M/N 30HXC206RY-540BA S/N 0702Q01190

CCP board 1 for compressors a1 & b1 which was recently changed is rev. 26
CCP board 2 for compressor a2 which came on machine from factory is rev.23
