RESMED S9 HUMIDIFIER

Hello
I am French and I can't find an answer with my technician for my RESMED s9. I 've slimline and humifier but the water is always cold even if the level is on 4, he told me that it 's normal because it's summer, my humidifier is on auto, could I change but how? I have very dry throat, thank you very much for your help but I can't access to the adjustment, I have an open padlock. Sorry for my English

First of all, are you certain that your dry throat is due to a lack of humidity? What kind of mask are you wearing? It is very common for those with nasal masks to open their mouth in the night and air escapes through your mouth, making your mouth and throat very dry.

If you are using the slimline hose, not the climateline, then there is not a setting for auto climate control--so are you sure that you have the right information here? Do you have the climateline hose? If so, you will need to get into the clinical menu to change the setting for auto climate control to manual. Hold the setup and button on top of the knob for 3 seconds and that will give you access to change that setting.

I have the same problem with the S9 not heating, cold plate and water in the morning.

My DME tells me the Pre-heat is the only way to get the humidifier to work. Pre-heat is activated by pressing and holding the round silver button for 3 seconds, then the machine can be turned on.

This doesn't seem proper to me, the need of a two step process to use the Humidifier. First step activating the humidifier pre-heat, then turning on the machine. I'm using the basic slim line hose that was included with my S9. Same problem using an old style large hose.

As pointed out, dry mouth can be caused by mouth breathing. Mouth breathing is bad when using a nasal mask. Ok if you use a full face mask. If you use a nasal mask I highly recommend you do some research. The air leaking out of your mouth is releasing pressure, pressure that keeps your airway open.

Just into my second month of using the S9 Elite, and I haven't noticed that problem. However, I do notice the red light that is supposed to come on when the heater is in use does not automatically come on when the machine comes on. I'm going to talk to my local Resmed rep and ask him about this. Should have an answer in a few days...if I can get in touch with him.

My lights work, rather have the heat working than the fancy lights.

The S9 humidifiers usually run on auto mode which means it only heats up enough to get the desired humidity level. This means that if you live in a humid climate it may not need to heat up very much. This is important to avoid rainout in the tube and mask. Also check to make sure that the two pieces of the machine a securely in place.

I watched the video but unfortunately I didn't see any remedies or solutions to my problem or the OP. I live in a dry climate, the two pieces are securely in place. My DME tested my machine yesterday with a new humidifier and it worked exactly the same. Your video didn't suggest the pre-heat mode needed activation before turning on the machine in order use the humidifier with the standard slim line tubing. Does this suggest I have a defective machine?

I was just thinking about the problem I'm having with my humidifier. DME explained yesterday that a two step process is required, pre-heat, then turn on the machine. This was after testing my S9 with a new humidifier or so they claimed. The RT took my machine and left the room to test it.

So far I have been turning only the machine on, expecting the humidifier to work. After turning the machine off in the morning even though the plate/water is cold, it goes through a cool down cycle. Per the instructions the blower can remain on for an hour, cooling down the humidifier.

If turning on the S9 doesn't turn on the humidifier, why is the cool down cycle necessary? Possible design flaw or is my S9 defective?

Still trying learn how the S9 works.

My old Respironcs turned the humidifier on automatically when the machine was turned on. This new S9 is a lot more sophisticated. I'm still having trouble getting my head around the fact it needs a two step process to use the humidifier.

I hope someone can confirm or deny this two step process my DME claims is necessary.


Thanks in advance for any help or suggestions.

The DME is wrong.

Pre-heat is just that. If you want the water pre-heated (that is, heated before you start the blower), you can optionally use the pre-heat function. If you don't care about pre-heating, just press the Start button and the humidifier will start heating concurrently with the blower.

"Cold" is a relative concept. While it may appear to be cool to the touch, it may still be warmer than the ambient temperature. The "cool down" function is to prevent condensation (from any vapour in the humdifier) occuring in the blower unit.

Are you using a Slimline hose or a Climateline hose with your S9+H5i?

Cheers,

Thanks Bill

I use the Slimline hose.

I was adding water daily to my old Respironics with the heat turned off. During the warm summer months I didn't need to add heat.

The first couple of nights my new S9 didn't use any water so I set the heat at 3 and didn't add water for over a week.

Once I did try using the pre-heat, waited, the water warmed, turned the machine on and went to sleep. I did turn the machine off and on during the night while using the restroom. In the morning the water and humidifier plate were very cold to the touch.

My old Respironics was using more water with no heat.

Could a wrong setting in my S9 cause this type of problem?

I'm trying to determine if something is wrong with my machine. From past experience I learned not to trust my DME. Right now I'm at a loss as to what is going on.

After checking my machine, I found out the lights are indeed working properly. The red light comes on when the humidifier is heating. Still no word from ResMed. It's like pulling teeth to get in touch with my rep. So, if indeed the red light is an indication that the plate is warming, mine is working just fine. I have checked the temperature of the unit after a night's use and it is slightly warmer than ambient air. I have my humidity cranked up pretty high, though, so that could be the reason. I'm using the climate line. This machine is brand-new to me as well, so I'm learning as I go. As soon as I hear from ResMed, I'll reply again.
Good luck and good sleeping!

The humidifier compartment should light up red when heating and turn blue when shut off and cooling down. If you want to check to see if it is working put your mask on and use it while watching tv for a half hour then remove the humidifier tank and feel the aluminium pan on the bottom it should be slightly warm to touch depending on the temp setting.

I have a three week old Resmed S9 and it has already blown out 2 hoses. This is pretty distressing. I had to cash in superannuation to buy it, and I need my sleep.

I am very confused !. I just started using this machine with a full facemask about a week ago and I wake up everynight with a very dry mouth. I took out my manual to see how to turn on the humidifier. On page 6 it shows a option of humidity level with a picture of a water drop. So I go to my machine and it is a different sceen. It says Climate control. Instead of a Humidity level of say 3.0 I get a screen that say 62 degrees and is adjustable up from there. I have turned,pushed,and proded just about every button on this machine and still cannot find a screen for humidity level like the one on page 6 of the users manual...... What am I doing wrong here?
