Fleck 5800 Programming Help

[jaeisber]

I recently installed a new Fleck 5800 Upflow system with 48,000 Grain 10% crosslinked resin. I decided to replace my previous softener (5600SXT / 48,000 grain) after resin failure caused a drop in water pressure. It was an older system, so I decided to replace the system rather than replace the resin. Prior to the resin failure, I had no issues with water softness. My settings were:

RF - dF1b
CT - Fd
C - 30x1000
H - 25
RS - rc
RC - 180
BW - 6
BD - 64
RR - 10
BF - 10
FM - t0.7

The 5800 came unconfigured, so I initially started with similar settings (minus RF, that was set to UFbd). However, water does not appear to soften at all and remains hard. Does not feel slippery like I expect. Tested water hardness is high, ~35gpg. Not looking to get it to 0, but certainly something significantly lower. I've tried adjusting the Hardness up higher, but that did not change anything. Looking for some help to get my settings right. Family of 4 (2 adults, 2 children), ~180gal/day usage.

Any and all help is greatly appreciated!

Any help would be appreciated.

What are the two numbers on the green sticker? Are there some decimal points?

I would expect the second number to be about 3x the first number.

What are the two numbers on the green sticker?

BLFC: 0.125 GPM = 0.375 lbs/minute

 

[jaeisber]

BLFC: 0.125 GPM = 0.375 lbs/minute

Correct, label shows .12 and .37

35 grains is a lot. If that is accurate, you should have gotten a much bigger unit. City water? With the high hardness compensation added, expect to regen about every 3 days. Maybe you should re-measure your hardness with a Hach 5-B kit.

Your back wash rate is lower than usual. I suspect you either have fine grain resin or a turbulator.

The big change in the numbers is for brine fill. Also note that the brine draw is longer, and should be 90 to 100 minutes with your violet 00 injector

Thank you. I will update my settings when I get home from work.

As for 35 grains, yes, I know it is a lot. City reports a low of 20 and a high of 35. City gets the water from a heavy limestone area and is notoriously hard. My previous system was the same size, just with a Fleck 5600. I had no issues with water softness or frequent regen, so I just went with the same size with the new system (hindsight 20/20 now).

Question, is this accurate? My 5800 was ordered as an Upflow, and I confirmed it was upflow based on the Part Number (580006-002).

I currently have RF = UFbd.

 

[jaeisber]

@Reach4 - Any guidance on the RF setting? My controller is an Upflow 5800.

You are correct to spot my error, and the UFbd is the right way for upflow. I edited my earlier post. Thanks.
