The
Fleck model 7000 control valve is unique in that it is rated for
higher flow capacities than most 3/4" and 1" control
valves. The Fleck 7000 is a 1-1/4" control valve designed
for residential use without the cost of a commercial controller
and will work on 3/4", 1" and 1-1/4" plumbing connections.
While it is possible to connect the model 7000 to larger diameter
water pipes, there exist many local ordinances that dictate piping
and connection sizing. Be sure to check yours before proceeding.
Except
for the piping connections, all of our Water Value water softeners
and auto-backwashing filters assemble in the same manner. The
media or resin tank arrives empty and the media or resin is added
with an included funnel. The drain line which is included, connects
the same way for a softener as it does a filter, and in the case
of a water softener, the brine line connects to the brine tank.
All of that pre-assembly and connection information is available
on our Water
Softener - Auto-Backwashing Filter Installation page. Photos
are provided along with detailed descriptions to help make the
job go smoothly. But different control valves require specific
setup and programming procedures which we will address here for
the Fleck 7000.
The
Fleck 7000 water softener/auto-backwashing filter control valve
is an electronic computerized device which needs to be programmed
prior to use. The service manual that comes with the model 7000
does an excellent job of demonstrating and describing the programming
and setup steps but there is more information in the manual than
is required to get the system up and running, such as information
pertaining to the Master Programming Mode which should be avoided.

The
Fleck 7000 conrtrol valve has an LED display with 4 indicator
lights. The "In Service" light means the controller
is operational. The "Program" light indicates
the valve is in program mode. The "Flow" light
flashes when water is flowing through the softener and
the "P.M." light is on when the clock display
is reading afternoon or evening.
|
The
up and down buttons allow you to change values based on which
display mode the control valve is in. If it is in setup time mode,
pressing the up arrow will increment the time of day and pressing
the down button will decrement the time of day. The "Extra
Cycle" button is used during programming to advance to the
next programming mode and will initiate a manual regeneration
when the control valve is in service mode.
There
are 3 different configurations for this control valve. One is
used for either auto-backwashing filter control which can also
work as a time initiated softener or manganese/greensand filter,
meter initiated softener control valve and a metered immediate
regeneration softener. These instructions will deal only with
the metered (on demand) softener control valve in standar programming
mode.
Once
the softener is connected to the water pipes, set the included
bypass valve on the back side of the model 7000 to bypass mode.
Open the water supply line to the rest of the house and open a
nearby faucet to expel any solder or debris left over from the
plumbing process. Once the water from the nearby faucet begins
running clean, shut it off. Plug the control valve into an approved
power source. Put the bypass valve into service position by first
turning the outlet (water out) side of the bypass to service and
then slowly turning the inlet (water in) side of the bypass to
service.
Check
for leaks. Set the time of day. Do not set the time to 12:01 PM
to avoid initiating the Master Programming Mode. Now press and
hold in the Extra Cycle button for 5 seconds which will initiate
an immediate manual regeneration. Step slowly through the regeneration
cycles by pressing the up arrow button until you get to the Brine
Refill cycle #5. Let the softener fill the brine tank and advance
itself to the In Service mode. You may now add salt to the brine
tank.
Once
the time is set and the brine tank has been filled, press and
hold the up and down buttons simultaneously for 5 seconds. After
5 seconds the Program indicator will light up. Release the up
and down arrow buttons. The display should now read "H -
9". This is the feed water hardness programming stage. Using
the up and down arrow buttons, adjust the display until the value
matches your water's hardness rating in grains-per-gallon. For
example, if your water's hardness is 18 gpg, press and release
the up arrow button until the display reads "H - 18".
You will also want to factor in any iron you may have in your
water as well.
A
standard softener can treat up to 2.5 parts-per-million (ppm)
of iron without the need for a seperate iron treatment system
so long as your water contains "clear water" iron. See
this article on how
to identify different types of iron in your water. Basically
add 5 grains per gallon of hardness to your water for every 1
ppm (mg/L) of iron. For example: 18 grain per gallon of hardness
with 2 ppm of iron would equal a compensated hardness of 28 gpg.
Let's
move on to the next programming step. Press the Extra Cycle button
once to advance to the Regeneration Time mode. The display should
now show "2:00" which is 2 AM because the PM indicator
light is not on. To change the time of day or night that you would
like your softener to regenerate (usually the time when no one
is likely to be using water), use the up or down arrow buttons.
Once
the desired time of regeneration is set, press the Extra Cycle
button to advance to the Regeneration Cycle Times display. These
are default durations for each backwashing cycle and should not
be adjusted. The first display is the Backwash Cycle Duration.
Press the Extra Cycle button to advance to the Brine Draw Duration.
Press the Extra Cycle button to advance to the 2nd Backwash Duration.
Press the Extra Cycle button to advance to the Rapid Rinse Duration.
Press the Extra Cycle button to advance to the Refill Duration.
Press the Extra Cycle button once again to advance to the 6th
duration cycle which is not used for the downflow metered configuration.
Pressing
the Extra Cycle button will now display the Extended Diagnostics
mode which will be of little use to a new installation. It displays
the number of days since the last regeneration. Press the Extra
Cycle button to display the gallons used since last regeneration
and the gallons of reserve left before the next regeneration.
Pressing the Extra Cycle button one more time results in the 7000
exiting the programming mode and reverting to the In Service mode.
Your
Fleck 7000 water softener system is now producing treated water.
Because your water heater tank may be holding several gallons
of un-treated water, you might not notice a difference while bathing
or washing laundry until the un-treated water is used up.
