NuArc N1500 xenon printer - manual?

[bobbotron]

I have acquired a nuArc N1500 xenon printer, I want to use for making cyanotypes and other UV processes. It's a great machine, but I have no manual to accompany it. I'm looking for guidance on the vacuum settings, and generally how to best use/care for it. From my basic tests, a print takes about 9 minutes. I'm curious on the duty cycle, ie should I run it for shorter intervals with a cool down period or can it go for 9 minutes in one go no problem.

(Edit: sorry, this should be under Darkroom: Equipment)

Email NuArc with the serial number and they will send you a pdf.

I have a same size NuArc vacuum frame only, no lamp or superstructure. I don't need or want the lamp

It has the NuArc pump, in VGC

I think it will run for hours and hours, but my duty cycle is minutes not hours

It is a vane type oil less pump that will wearout vane parts, but is rebuildable. NO OIL EVER

Look at the glass bottle filter for excessive dust, clean as needed, mine was cleaned once when I got it years ago, still clean

Mine had a vacuum hose failure under the mat, new short hose, OK!

I watch my vacuum gauge to see if suction is perfect

Steady over -15 is good enough
