Author Topic: No flow error in kinoton DCP70L projector Peter Fagan Film Handler Posts: 17 From: Letterkenny, donegal, Ireland Registered: Aug 2012 posted 02-07-2019 02:09 PM                        Hi Guys. I'm having a bit of an issue here with one of my series one kinoton projectors.this last while i have been getting a flow error message.once i bleed it it is fine for another day or 2 but i ordered a new pump from kinoton.installed it today but now i cant get the flow to go once i have everything connected up.if i bleed it out the light goes green again but once i connect the pipe to the light engine again & complete the loop again I'm getting the flow error message again.Any body come across this or have any ideas what to try as I'm kind of at a loss here now at the minute.Cheers.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

I noted on the coolant change that it really wasn't drawing the new coolant in as fast as normal. I had to flush out the lines real well and then BOY did I have flow and a bazillion air bubbles. Took about 40 minutes to get them all out and it has been fine. Perhaps have something similar. Also, don't discount the possibility of a bad flow meter (not knowing the type they are using).  |  IP: Logged Michal Matys Film Handler Posts: 70 From: Prague, Czech Republic Registered: Nov 2014 posted 02-08-2019 02:01 AM                    Hi, Had this few times on Kinotons, probably air is stuck in the engine. You can try to "flush" it with high preasure with destilated water, or just dont use original Kinoton pump since those are rather weak and buy new stronger garden pump and connect it to the projector, will work fine for several years after that for you. We have 30L projectors but I guess that should not make a difference.  |  IP: Logged Marcel Birgelen Film God Posts: 3357 From: Maastricht, Limburg, Netherlands Registered: Feb 2012 posted 02-08-2019 01:42 PM                     If you bleed it and it's fine afterwards, but builds up over a short period again, it seems you've got a leak somewhere, that allows air to enter the system at a higher rate than usual. But usually, where this happens, there is also a leak where you're losing a bit of coolant. Have you checked the inside of your machine for buildups of coolant residues? I've never tried this myself, let alone on a projector, but I've head about people using colored UV activated dyes on all kinds of machinery together with UV spotlights, often used to find leaks in cooling systems of automobiles to locate coolant leaks.  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 02-08-2019 02:01 PM                     Kinoton S1 coolant flow. Make sure the pump is turned to full speed. As said above, bleed, bleed and bleed again. Replace the QD connectors, they age and restrict flow. There is/was some sort of modified flow sensor for these, but I'd have thought they'd all have been changed by now. We have been researching a chemical flush for these aging systems, not ready with it yet though.  |  IP: Logged
