Question

Postby racermpn » Tue 05 Aug, 2008 17:42

I am not sure if it is reverse polarity or not. It seems as though the 10 amp charger cant keep up with the pump. When the unit was working you could see the chlorine coming out. Now with just the charger hooked up all you can see is tiny little bubbles. Show I use a 15 amp charger. Does anyone know how many amps the original intex unit puts out to make the chlorine???

first check if you have the correct polarity

blind guess would be that it needs 20-25 amps
you can estimate if you know what's the unit's power rating is, although manual should have how many amps/volts the output is

Well, it seems that there is definitely a problem with this unit design. My unit has only about 30 hrs on it but is not under warranty any longer as I bought at the end of summer 2006. I set up the pool last weekend and got the code 91 right away. This is only the second time this unit has been in service. I shut the unit off and on few times to see if that would clear it, it didn't. I did all the other cleaning things to. I left the unit off for a day but it was still plugged in and the power unit was pretty warm to the touch the next day but I went and turned it on anyway. The LED comes on with code 88 and when I try to enter the system I get rapid beeps from pressing the up arrow key ( the down arrow key beeps only once after 5 seconds as discussed in the manual ) and nothing else happens so I can't enter in any operational hours or anything. I unplugged it and let it sit for a few hours and tried again but no change.

Does anyone have any ideas about this problem, could it be the power unit?

I discussed this issue with Intex and since it is out of warranty they won't replace the unit but they also said that their trouble shooting tech thought it was an internal malfunction and since they don't sell internal replacement parts the unit needed to be trashed.

Looks like I need to follow some of the "fixes" outlined in this thread.

Would like to follow up on the battery charger thing so if anyone has any more info on that it would be appreciated.

intex

Postby racermpn » Thu 07 Aug, 2008 10:16

Here are the specs for the intex machine

Power 110-120 volt AC
Amperage 2.5A
Wattage 250W

Is a 10 or 20 amp charger going to be too much. I am not an electrician so I just don't know.

you should have roughly 20-25 amps

Thx for the responses guys.

Now, to show my ignorance of electrical stuff. From a previous post the poster measured the volts at the cell from the Intex transformer to be 18V. I presume that this means that the transformer is converting the 120VAC down to 18VDC which then is used by the cell to generate chlorine. If the Intex power unit is using 2.5 amps to generate 18VDC why does it take a 25 amp charger to provide 12VDC?

Just an update to my problems. I gave the 8110 a try again last night an to my surprise it actually allowed me to program a run mode. So I programed a 4 hr period and after about 2 min it code 90'd low flow, which was a crock, so now I know that this thing is definitly screwed up and I have no problem with getting in there and trying these fixes to limp through the next 4 to 6 weeks of pool time.

Cheers

If the cell voltage is 18V - you will need around 15 A. I was assuming voltage of 12V.

The transformer takes 120 VAC to 18 VAC, which will end up ~13.5Vdc after it is rectified. This is a self cleaning unit, it reverses the polarity to the cell on a regular cycle. You could bypass the internal controls if you get a heavy duty rectifier, connect the transformer output to it, then to the cell. If you put a DC ammeter in line you have a quasi salt level meter! I don't think that the flow meter is rated for 120 V, 2.5 amps, but if it is, it could be wired into the transformer input - no water flow would mean no power flow. Plug it into a timer and you're all set for automatic operation, just remember to reverse the cell polarity to clean it every so often.

Uh, did you put a meter on it? I got 16.8VAC out of the Transformer, which rectified to 22.8 VDC coming off of the big honkin' Capacitor. The transformer also sends 9.4VAC to the control board for 12VDC timer and stuff. The rectifier fan should be powered whenever there is load on it, or a great big ol' heat sink should be installed.

I tried the R1 pot adjustment I turned it 1/4 turn CC it stopped the 91 alarm, I have had 3 of these units and they all have had cell problems. It would always happen after winter storage they would work all summer after winter no go.But it was cheaper to buy the whole unit than it was to buy just the cell.

What's the fix? My Intex keeps giving me the 91 (low salt/no salt) error code???

My 8110 has been terrific for several years now. Startin up this year I am getting the 91 code even though I know there is plenty of salt in the pool. I would be interested in the "fix".

Man, what a crap this intex chlorine generator
also have this annoying code 91 problem...at my very first use, tonight
i put inside my pool 75 kg of salt, where the manual says 55 kg.
and i keep getting this code...
the led pass to the green then the cell unit seems to work for 1 minute, i can see the chlorine mist going inside the pool, so i think there's enough salt inside...then it sudenly stop...and beep

it seems that changing the system using the warranty, is no longer a seals of hope to answer the problem.
i will try the hour modification fix.

This has been the most helpful site. I thought we were the only ones having trouble with our chlorinator from intex. Our problem is that the unit goes on for a few minutes after it's plugged in then it completely shuts off. We've had our unit for two years, so we are no longer under warranty. My husband called customer service and some lady said we had a two year warranty, so he faxed the information with receipt only to be told what we already knew-we are no longer under warranty. Anyway, I came across this site and I told my husband to start messing with it - he's an electrician- so I'm hoping he gets it to work. Thanks!
