need clean water for modular chillers period. so as long you have some type of strainer system in place should be ok, the maintenance is pretty extensive on the modular plate and frames as well.

Serial 11531c53527467

Chiller was dated 2015 and had danfoss exv customer and installer both say no one from jci contacted them

there is known tech bulletin out on the problem i saw it for chillers made in 2015 i think

THis gets better this chiller was made in 2015 found out JCI had a bulletin "brazed plate HX freeze damage-KDD that required modifications etc. Was never completed. SO customer is asking...

where can we find out if the serial number applies to the bulletin?

They are replacing the danfoss with Copeland scrolls FYI Carrier is recommended this. So if this the case can you mix and match them with danfoss and a Copeland in the same circuit?

guess wjat the factory or any other manufacturer would rather sell you new equipment than test alternative freons so it wont happen. Use common sense here POE oil to replace MIn must be 300...

anyone know where to get a copy of vision plus software to install to access a system via phone modem?

double check the water flow valves sometimes if flow is diverted it can cause the noise as well, I know mine does it once in a while.

Had old 1990's supervision software computer crashed its gone. WHere can you buy new software and license to access ALC system from phone line remote???

Recently had a ignition problem did the factory check out procedure of Robert Shaw inter pilot board check voltage, spark etc numerous times was checking PV to common at ignition module...

Yes ;most of these chillers had the exv on them, we are in process of converting over to regular txv with drop out solenoids. Hope we can bypass this end of the board and get the unit working...

Main boards for these chillers 30gb501... is obsolete. For some reason carrier figured we better stop making them??? So dilemma is we need a new board, the local carrier dealer wants 7k for new...

From what I read the pressure should be highter during unloading. I think using an adjustable oil diff control is the best way, you can set it the way you want it.

Any follow up to this post? Had a prospect ask me to quote retro fitting an old mcquay centr chiller to 3 turbo cores....I said no way! not us....... I would rather see you invest in a new chiller...
