Struggling with KH Director Setup

[pokesmotrva]

Good morning,

I followed the setup video precisely and ran a test. Test came back a little high, but I was okay with that (10 instead of 7). I ran another test later, and got tritation took to long error. I reran again, and this time a tube shot off. The tube between pump and KHD for waste water.

I tried again the next day (the first day of setup / testing took most of the day). Again problems. I recalibrated all the pumps, ran a test and got nearly perfect results. I left it alone to run it's auto test at midnight.

This morning, the sample line between pump and KHD AND the waste line between KHD and pump were both disconnected, with water all across my garage.

What could be happening? How do I fix it?

Thanks in advance.

you have a photo of the install? how old is the khd??

[pokesmotrva]

I purchased the director 6 months ago. The photos of install are below:

Have you not got the nozzles that connect the lines to the dosers? Like in the picture https://uploads.tapatalk-cdn.com/20200526/aa91f8ac733772da697fc6087af0d01b.jpg

Oh, dear. How silly am I? I'll add them now and try again.

I've added the connectors - I don't know how I missed that, but I think it wasn't mentioned specifically in the instructions and I'm dumb.

Do I need to recalibrate everything now that it's connected correctly or will those impact calibration?

Also, sorry for multiple posts, but would those really have any impact on the hoses shooting off the line?

[Vinny]

No, it will not impact calibration.

[pokesmotrva]

No, it will not impact calibration.

I've run 3 tests in a row; all 3 come back with "Titration too slow". Any advice? At least none of the lines popped off so far!

you have a full tube at pump 2 with the reagenz?

Yes the entire tube is full of reagent. I have tried 5 tests. One successfully completed with expected results (6.9 - manual test was 6.5). The other 4 times it has taken too long.

Is your vent tube setup properly? Not submerged or connected anywhere

this wars also my dea, an the question, how old the khd is. the first version has a silencer in the vent tube, you have to remove.

The khd was purchased 6 months ago. I have no idea which version or how to tell. The vent tube (which isn't referred as a vent tube on the setup video) is run outside since the setup is in my garage right next to the door.

I just realized that the setup video I followed mentioned nothing about venting internal reagent tube. The PDF guide I'm reading has this listed as step 1. I guess I'll try that and rerun the test?

I followed the PDF guide I found, and vented the reagent line. I ran a test and it succeeded, but gave 0.0 dkh result. I ran it again and got 7. This is relatively in-line with expectations, as the manual test I did yesterday was 6.5.

I will run another test, and if it's successful call this matter closed.
