5810 SXT Settings

[RSNovi]

Hi,

I have been living with the new softener for a couple of weeks now and we are quite satisfied with the water. I don't know if my settings are optimal. I have only adjusted a few using the simple menu. Please help me make sure everything is correct. Also I have some citric acid to add to the salt, but I haven't done that yet. I plan to with my next refill on salt.

Two adults and two children living in the house.

Here is my initial water test:

• Hardness= 19gpg
• Iron= 1ppm
• Total Dissolved Solids= 304ppm

Here is the meter from the quote that I was sold:

• Softener 2.5 CF Meter 1354Black/5810SXT

I only have accessed the basic settings:

DO = 7 (I found some advice to lower to 7 if you have iron??)
RT = 2:00
H = 24 (I found some advice to increase by 5 for every 1ppm iron??)
SF = 10

I pulled the other settings below from another recent post, but I haven't poked around with them yet.

DF =
VT =
RF =
CT =
C =
RS =
B1 =
Bd =
B2 =
RR =
BF =
FM =

Thanks in advance for your advice.

Chris

BLFC = what? 0.125 and 0.250 are most likely. Look for white label visible near the back after the cover is lifted.

Also provide injector number if available.

If you don't know the BLFC, what are your current C and BF values?

Thanks. I will plan to look for the label this evening.

Fleck has recently started using the color coded stickers on the BLFC, it may be located on a green, blue or black sticker (metallic) near the brine connection.

 

[Reach4]

Oops. I was picturing the injector and DLFC (drain flow) label...

 

[RSNovi]

Is this helpful?

Here are the rest of the settings.

VT = 5810
RF =dF2b
CT = Fd
C = 60.0 x1000
H = 24 (I found some advice to increase by 5 for every 1ppm iron??)
SF = 10
RS = cr
DO = 7 (I found some advice to lower to 7 if you have iron??)
RT = 2:00
B1 = 6
Bd = 60
B2 = 3
BF = 6
FM =t1.2
RE = OFF
VR = OFF

C=60 and BF=6. Wow.... Doesn't quite fit, but it is close to implying more than 1.0 gpm BLFC . C=60 implies 8 pounds of salt per cubic ft of resin.

I would check the BLFC button, if it were mine. Note the marking (250 I think). Don't put it back backwards. They look like just a rubber washer at first glance, but it matters which way the flow goes. The 0.25 is probably correct, and I presume that for these suggested settings below. I also upped the H a little more for high-hardness compensation.

BD at 60 might be enough, but I would go to 80 myself. 89 would be the number for a full 4x times the time it takes to suck out the brine.
I upped the DO to 14 from 7. Do add some citric acid or other rust-handling additive.

System info (not programmed)
salt lb/cuft : 7.8 ; A choice ( efficiency vs capacity)
BLFC : 0.25 ; Brine Refill rate GPM
cubic ft resin : 2.5 ; Same as (nominal grains/32,000)
Raw hardness : 24 ; including iron etc
Estimated gal/day ; 240 ; 60 gal per person prediction (auto-tunes)
Est days/regen ; 9.11 ; presuming days each use estimated

Fleck 5810SXT Settings:
DF = Gal ; Units
VT = 5810 ; Valve type
RF = dF2b ; Downflow, Double Backwash
CT = Fd ; Meter Delayed regen trigger
C = 59.1 ; capacity in 1000 grains
H = 27 ; Hardness grains after comp factor
RS = cr ; Cr = base reserve on recent experience
DO = 14 ; Day Override (typ 30 if no iron/Mn)
RT = 2:00 ; Regen time (default 2 AM)
B1 = 5 ; Backwash 1 (minutes) [3...10]
Bd = 80 ; Brine draw minutes
B2 = 4 ; Backwash 2 (minutes)[3...10]
RR = 6 ; Rapid Rinse minutes
BF = 26 ; Brine fill minutes
FM = t1.2 (usual) ; t1.2 is default flow meter
RE = OFF ; Relay
VR = OFF ; ?

There are alternative combos of C and BF that you could use if you wanted to use less salt.

Thanks. I will check the BLFC fitting. I found it in the parts diagram and will look into it tonight.

 

[RSNovi]

I am sorry Reach4. Typo on my BF. It is currently set to 16.

 

[Reach4]

Expect 250 25 where this one shows 123. (corrected with info from RSNovi)

If you check the #1 injector, expect to see white where the red is under the cover:

 

[RSNovi]

Looks like a 25

Sure does. I am confident that is a 0.250. I just didn't know how they marked them, and I had not thought it out. The 25 makes sense.

0.25 gpm BLFC is exactly as printed on the label shown in the photo attached to post #6.

To regenerate 60K capacity in a 2.5 cuft unit, will require 20 lbs salt. As each 1 gallon entering the brine tank will dissolve 3 lbs salt, to dissolve 20 lbs will require 6.67 gallons. For 6.67 gallons / 0.25 BLFC = 26.67 minutes BF. Because BF is typically whole minutes, always round up.

When a softener is exposed to a substantial quantity of iron, the salt setting needed often cannot be as efficient as when there is no iron. The water's pH can affect the salt dose needed as well as the quantity and frequency for treatment with Iron Out or similar.

 

[RSNovi]

Thanks all. I updated the settings per your recommendations.

Original BD was set to 6. Checking that the BLFC matched the label was worthwhile.

Because BF is typically whole minutes, always round up.

Not always. Capacity setting has great resolution.

There are a lot of good combos of C and BD, especially when the BD time is longer. Below are reasonable choices:

lb/cuft ; C= ; BF=
5.100 ; 45.9 ; 17 --more radical salt savings, but still not to California standards.
5.400 ; 47.2 ; 18
5.700 ; 48.6 ; 19
6.000 ; 50.0 ; 20 --For lower salt use. A common choice for salt economy
6.300 ; 51.5 ; 21
6.600 ; 53.0 ; 22
6.900 ; 54.6 ; 23
7.200 ; 56.1 ; 24 --Moderate choice.
7.500 ; 57.6 ; 25
7.800 ; 59.1 ; 26
8.100 ; 60.5 ; 27
8.400 ; 61.8 ; 28
8.700 ; 63.0 ; 29
9.000 ; 64.2 ; 30 --Less hardness bleed.
