Fleck 5600 capacity numbers

[Sponge bob]

I just installed a 48,000 with a Fleck 5600. The tank came prefilled with resin. The instructions said I should only have to change hardness. I looked at the setup menu just to see what settings they had put in. The valve was set to 30,000 and the associated back wash, brine, etc times were also set for a 30,000 capacity system. I thought maybe they had only given me 1 cubic foot instead of 1 1/2 of resin, ( I am not sure how to check now I have it running). When I contacted the company they said it was more efficient that way running a 48,000 at 30,000 settings. Is this accurate info?

Yes!

To regenerate 30K grains per cycle will require only 9 lbs salt (6 lbs per ft3 resin). (30,000 / 9 = 3,333 grains per lb)

To regenerate 36K grains = 12 lbs salt (8 bs per ft3). (= 3,000 grains per lb)
To regenerate 45K grains = 22.5 lbs salt (15 lbs per ft3). (= 2,000 grains per lb)
To regenerate 48K grains = 30 lbs salt (20 lbs/ft3) (= 1,600 grains per lb)

The usually recommended salt settings for efficiency and water quality are either 6 lbs/ft3 or 8 lbs/ft3.

Which Fleck 5600 controller is your unit equipped with? The most common is the SXT which has a digital display, but there are also other versions.

The controller is the Fleck 5600SXT. The resin tank is 54" x 10"

 

[Bannerman]

That is the appropriate size tank for 1.5 ft3 resin.

There is most likely a label located close to the brine line connection which will specify the Brine Line Flow Control flow rate which is the refill flow rate for water to enter the brine tank. Most 5600SXT valves are equipped with a 0.5 gpm BLFC flow restrictor, but there are other restrictors that are sometimes installed so it is good to verify.

The BLFC flow rate X the Brine Fill setting in minutes, will equal the total quantity of water to enter the brine tank. Each gallon will dissolve 3 lbs salt so to dissolve the 9lbs required for your current 30K grains Capacity setting. then 3 gallons of water will be needed. Assuming a 0.5 gpm BLFC is installed, then for 3 gallons to enter the brine tank, the BF setting will need to be 6 minutes.

The label next to the drain line says "drain flow 2.4 GPM"
The label near the brine fill fitting says "0.5 GPM"

Is this accurate info?

Yes.

The "48000" should not be used for calculations for normal use. Think of it as a convention.

Where can I find a listing of all the recommended settings for a 48,000 grain softener?

I can do that, or your seller will do that.

If you search for "Fleck 5600SXT Settings" in the search box above, you will see a lot of prior examples.

 

[Sponge bob]

The seller gave me these numbers;
hardness 25
SF 20
BW 6
BD 50
RR 6
BF 6
capacity per unit 30,000
drain line flow control 2.4
brine refill rate 1.5
injector size 1

My hardness when tested with a Hach 5B kit was 10 grains per gallon.

If not city water, what are iron and manganese numbers?

If tuning for less salt use or softer water, which way would you lean? Midway?

Not important for settings, but I can throw number of people into the number.

 

[Sponge bob]

It is city water, I don't have iron or manganese numbers.
Lets go midway and tell me what to change to move it either way.
Typically 2 people.

System info (not programmed)
salt lb/cuft = 7 ; A choice ( efficiency vs capacity)
BLFC = 0.5 ; Brine Refill rate GPM
cubic ft resin = 1.5 ; ft3 resin = (nominal grains)/32,000
Compensated hardness = 11 ; including any compensation
People = 2 ; gallons affects reserve calc
Estimated gal/day = 120 ; 60 gal per person typical calc
Estimated days/regen = 25.04 ; Computed days including reserve
Fleck 5600SXT Settings:
DF = Gal ; Units
VT = dF1b ; Downflw/, Single Backwash, black cam
CT = Fd ; Meter Delayed regen trigger
NT = 1 ; Number of tanks
C = 33.9 ; capacity in 1000 grains
H = 11 ; Hardness-- compensate if needed
RS = rc ; rc says use gallons vs percent
RC = 120 ; Reserve capacity gallons
DO = 30 ; Day Override (28 to 30 if no iron)

Revised based on number from https://terrylove.com/forums/index.php?threads/help-for-programming-fleck-5810.82673/#post-595983
BLFC = 0.5
cubic ft resin = 1.5

Alternative C and BF pairs:
lb/cuft ; C= ; BF=
5.000 ; 28.7 ; 5
6.000 ; 31.5 ; 6 ; from dealer
7.000 ; 33.9 ; 7 ; *used above
8.000 ; 36.0 ; 8 ; good choice for a little softer
9.000 ; 37.7 ; 9

The settings are changed, thanks for the help.

I just happen to read this post after just programming my softener and I'm a bit confused. I have same exact setup...5600 with 10x54.
I set the capacity to 48K as it shows in the chart I had seen somewhere else....but the chart on the link above, shows a few possibilities.
I have well water with 6 grains of hardness. I also have neutralizer after the well which I assume adds approx 6 more grains.
5 people in house with low flow faucets/showers and front loading washer/dryer and dishwater that gets used every other day.

How do I determine what I should set mine too?

I"m assuming i can just use sames settings above?

Probably. You should get a Hach 5-B test to measure your hardness out of the neutralizer.

You have a 5600SXT. There is a timed mechanical softener called the 5600 with no suffix.

sorry...one more question.

C = 33.9 ; capacity in 1000 grains
Am i making the setting 33? or 39 (per the chart)

[ditttohead]

10x54 should have 1.5 ft3 of resin. For reasonable efficiency and quality water, set to 36,000 grains and 12 pounds of salt.

 

[Al Garrido]

I'm sorry for the stupid questions as I'm just learning more about this.
So I'll set the setting to "36"
....but you say to set to 12 pounds of salt?...is that a setting I have to set?

I'm using the settings from above:

Fleck 5600SXT Settings:
DF = Gal ; Units
VT = dF1b ; Downflw/, Single Backwash, black cam
CT = Fd ; Meter Delayed regen trigger
NT = 1 ; Number of tanks
C = 33.9 ; capacity in 1000 grains - I'm setting to 36
H = 11 ; Hardness-- compensate if needed
RS = rc ; rc says use gallons vs percent
RC = 120 ; Reserve capacity gallons
DO = 30 ; Day Override (28 to 30 if no iron)
RT = 2:00 ; Regen time (default 2 AM)
BW = 5 ; Backwash (minutes)
Bd = 50 to 60 ; Brine draw minutes (60 typical)
RR = 5 ; Rapid Rinse minutes
BF = 7 ; Brine fill minutes
FM = ____0.7

Because I chose 7 minutes( midway between the more common 6 and 8), you use 7 lbs of salt per cubic ft or 10.5 lb of salt total.

If you select BF=8, you use 8 lbs of salt per cubic ft or 12 lb of salt. Then you would use C=36.0. Those are all nice values balancing salt usage and softness. So let me rephrase that. If you use C=36.0, then use BF=8.

awesome! thanks for the replies!
