[Equipment] What to look out for in a used machine?
#1
What to look out for in a used machine?
I appreciate the help I have received with steering me away from an ASV machine for my wife in this thread.  

Now I have found a good candidate for her, a Resmed Airserve 10 Autoset.  According to the seller the machine is fairly new with 208 use hours, and the seller wants $300. 

I'd like to know if there is anything in particular to look for, or to watch out for.

Thanks again or all of the help in this forum.

Jerry

Ask for an image of the machine Run Hours. 20,000 is near end of life on ResMed 10s, and unless really cheap I'd pass if it's close to that.

Make absolutely certain what machine the seller actually has. The gold front name and maybe the back label images would be helpful.

You will want to avoid the machine from a smoker in the house. Yes there's ways to clean it, but I'd avoid that.

You're going to want to run it before buying, assuming your picking it up. Strange noises would be a warning flag to me.

That sounds good.  The ad actually says it has 204 hours.  I will look at it tomorrow, and I will be able to turn it on and see the different screens.  Does it need water in the tank to turn it on, or will it run the motor without water?

Here are a couple of the machine from the ad including the hours screen:

I'd put a moderate amount of water in the clear tub on the right side. That is the humidifier tub, and either that tub or a block plate needs inserted in that recess for air to flow through the hose.

To get the tub out: from the front and using right hand, squeeze the top and bottom of that tub a bit, you may need to lift the bottom edge some as well, then pull straight to the right end.

To open the tub, look along the far right edge, there's locking tabs in the middle. Pull out a bit till the top lid is released. It'll hinge from there.

those run hours are accurate, and very low. there are codes on the bottom that you can determine where it was manufactured as well as the date it was assembled. you can google the codes.

if that's local to you, i'd certainly go look at it. just check it to see if it's excessively loud. it shouldn't be. also just look for physical damage (cracked plastic, etc).

it will run without water. i never humidify my air. you can also get another end cap (sans water tank) that makes the machine smaller. i have that.

good luck. that's a decent price.

Good price and practically new. The only thing I would absolutely verify is non-smoking household. It looks like you found a winner.

The SN can tell you manufacture date and factory.

example: 231512xxxxx

this example shows country code 23 (singapore), 22 would be australia.
15 is the year (2015)
12 is the month (december).

I bought the machine.  It looks perfect.  It runs very quiet.  It's clean.  It doesn't smell, and is from a non-smoking home. 

Now we need to get a mask.  

She would like to try nasal pillows, and she has a very small nose.  I'm guessing something in the XS size, but is there a way to measure anything to get an idea of size to start with? 



The S/N is interesting because if the advice above is correct it would have been built in the 13th month of 2015.  I guess they have more months in Singapore.

I was under the impression it was the week of the year and not the month.

I would guess that you're correct.  I've seen that on a lot of other serial numbers.
