Please don't cut-n-paste Google searches, it's like that joke about teaching pigs to sing.

Anyway, the closer a filter is to the fan intake, the cleaner your system will be; less...

Did you reboot the JACE? Changes won't take if you don't reboot. Also it might be the DNS. Use the host's IP address or you can set up the JACE with a DNS server.

Where do you live, or want to work? What city & state?

You can buy a new, warrantied, properly engineered Donaldson brand for anywhere from $1500 to $6,000. 'Plug-n-Play'.

"Hello, I'm Rick" probably would have been a better introduction. Plus:

1)What you do for a living.

Follow Chiller Man's directions. But here's a tip for the older (mid 90's) chillers: the first 30GXs didn't have O-rings on the oil level sensor fittings and tended to leak there (among other...

Brilliant!

You've just sold me. I'm going to try SG for everything now.

I did a quick search and it looks like your plan to use simple green is a good one. I didn't think it would dissolve dried ink, but many people have used it with success.

I've heard "Gonzo" works...

What type of ink? You'll probably need some kind of solvent.

Nice clean removal BTW

That's very cold, even for a data center. Despite what the IT guys say, the best environment for electronics is a steady 70° - 72°f at about 50% RH. Too cold and you can get condensation forming...

What is the nature of the noise? Is it a 'sound', or is it vibration felt inside the building? Is it a mechanical or an 'air' sound? Is it steady, rythmic, rattling, rumbling, thumping, whooshing,...

Yes to the traverse. Can you see condensation overflowing the pan and running down the duct, or condensation being pulled off the coil by high air velocity?

What it is design CFM and what are the...

I can never remember the exact wording of all those alarms, anyway, glad to you got it worked-out.

The software for the touch screen should be on the cpu's flashdrive. A quick way into the system without using the touch screen is to get a regular keyboard: with either a usb or the old PS2...

I haven't seen any lit on this either, but if you're familiar with the machine you should be able to discern whether or not you're leaking-by by reading the line pressures at the lube box while you...

Drivers for the Windows CE OS touch screen can be found here. Or you can get them from McQuay. Is your chiller a new MicroTech II or has it been upgraded with a new MicroTech II control panel with...

I don't recommend bypassing the oil level switch; if there isn't enough oil to maintain lubrication the damage to an 06N can be catastrophic, and compressor replacement is inevitable. Carrier's...
