Thank you for this advice: my CPAP can not start; when I press the start button: the screen lights up but it seems that loop without passing the startup stage ..that you advise me to do ??

It looks like the honeycombed 'airflow baffle' in step number 8 is reversed in direction in the elite victim relative to PR's linked pictures of a v-auto victim. But somehow I doubt that it matters.....

it doesn't... I've checked. internally, the structure is the same in either direction, a smooth bore tube with a honeycomb baffle in the center between the two taps for the flow meter.

get your power supply checked.

WOW Thank you! You cant know how much this helped me out of a jam my new insurance company cant help whats so ever , I'm having some difficult time locating a new filter housing or holder for this . thank you again. Phil

Hey nashbridges those instructions are spot on. Fixed my wife's s9 in a matter of minutes. Don't take any guff from those that can't appreciate proper advise or instruction they could not give or write themselves. One question though does the board need to be powered up while replacing battery I have heard conflicting info about this 50% say just replace, 50% day must have power applied during replacement so you don't lose keep alive voltage? Thanks

Hi everybody!
I did the disassembly, and found my S9 loose on expiratory after assembly, but I tested on barometer and the pressure is OK. I disabled EPR too. Anyone ever noticed the same? Any help?

I'm afraid I'm not following exactly what you mean, but I haven't noticed any differences before or after reassembling an S9.

make sure the pcb is seated properly on the three air ports, and that the blower assembly is back together properly, snugly screwed together, and the wires from the blower are exiting the assembly properly (as shown in the disassembly pics)

Hi palerider and everybody!
I disassembled and reassembled again. I noticed that the board is 1-2 milimeters up, I think is because of the baffle rubber, when I tighten the screw board, it gets normal. I washed this rubber, I think it needs some oil, silicone to fit better. or something that can fit the rubber on flow sensor better. I think my rubber is like a folded hose now, but I is impossible to see or check after screwed. Any Help?

I'm not clear what parts you're talking about.

"baffle rubber" is the rubber that connect baffle to air flow sensor. I think this rubber is like a folded hose after screwed, but I can't see to check. I think it needs some oil, to fully connection, but what a kind of oil?

the flow sensor, or the pressure sensor?

I wouldn't use any lubrication *at all* on there, because if you get any liquid fouling the sensors, then that's game over.

The flow sensor. This rubber that I told is the tunnel rubber of baffle.
I'll just spread oil too thin, not drip.
But what kind of oil will not deteriorate the tunnel rubber?

there are two tubes on the flow sensor, again, I wouldn't put *ANY* oil of any sort on there. it never had oil on it, it shouldn't have oil on it. that's all I'm going to say on the matter.
