GHL KHD Reading Low

[Not an IT guy]

That’s an interesting theory. I’m gonna go test that. It’s a 125 with probably a 30 gallon sump

I have the same size. My sample size is 70ml. Hmmm. I cut V slots at the end of my line just case Head speed but you already confirmed it. On the reagent head speed did you calibrate it at the slow speed or fast speed?

Should I go with the 70 ml sample size?
And slow speed, thats what the video said to do so I just followed it lol

 

[Not an IT guy]

You can try it. I just changed it to 70 because 50 was too small and 80 means I have to refill my saltwater bottle every 5 days.

Cut a V in my line and calibrated my waste water pump one more time, back to 5.3 dkh so, I am out of ideas. Maybe the tubing I am using on the reagent is the wrong kind? Would that even make a difference?

 

[Not an IT guy]

What type of tubing are you using? Not the squishy kind right? It has to be the pvc type and the right diameter.

 

[Cheesus]

I was using the squishy but now the sample and reagent are on the PVC stuff from GHL

 

[Not an IT guy]

Was this a new or second hand unit?

 

[Cheesus]

Yeah it was.

And what’s the manufacturer’s date

Did you open it up as well? Here’s a photo of my inside. See if you see anything out of the ordinary

Verify that white line inside the pinch valve isn’t collapsed. You can remove it and and squish it back. If it stays collapsed that could be the issue. Not enough reagent being allowed in.

 

[Not an IT guy]

There’s two different versions of the tube. If it’s the old version that can be at fault. Ghl confirmed that

December of 20 it looks like, I will take it apart sometime today and look.

I think you’re ok. You got a newer version khd. Mine is from 2018.

 

[Cheesus]

Well it just gave me a 0 reading, thats new. Should I still take it apart or wait for GHL support?

Zero means no sample or no reagent detected. I’ve been through the 0 reading debacle. More than likely if it’s Vinny that’s helping you they will ask to open it. I say go for it. Take pictures inside as they might ask for them. They did with me anyway. And reference the photo I uploaded.

 

[Not an IT guy]

From the reagent bottle to the pump head, is it a short run?

 

[Cheesus]

Yeah its decently short. like 22inches

 

[Cheesus]

How do I take this thing apart?

How do I take this thing apart?

Underneath there are four tx screws on each corner. I forget the size 5 I think. Just be careful popping the top as the led wire is attached to the top.
