ALL UNITS NOW COME WITH THE NEW VORTECH
* NO GRAVEL IS NEEDED
NOTE: Product Change for MBA-AN-1229 ACID NEUTRALIZER
The brine plug (1030334) was added, and the brine sight glass
connection is plugged with a red cap (TV-6A Red Cap). See
Figure below. DO NOT REMOVE CAPS OR PLUGS.
NOTE: THIS FILTER IS NOT INTENDED TO BE USED FOR TREATING WATER THAT
IS MICROBIOLOGICALLY UNSAFE OR OF UNKNOWN QUALITY WITHOUT
ADEQUATE DISINFECTION WHETHER BEFORE OR AFTER THE SYSTEM
System Description:
The filter tank has a Logix top mounted automatic control valve with
an electronic time clock to initiate regeneration. The Logix Valve is
constructed of non-corrosive Norylmaterial and is rated at a
maximum working water pressure of 100 psi. It uses a 742
microprocessor based timer to actuate regeneration in the following
ways:
a.Manual regeneration button to start an emergency
regeneration
b.Regeneration day setting

3
Filter Positioning:
1. Place Filter in desired position, far enough from walls and other
obstructions to allow for servicing the unit.
2. Place the Filter within reasonable access to a grounded 115V/60
HZ circuit and a legal drain line connection.
Filter Tank Loading:
1. Remove yellow caplug from top of tank. DO NOT CUT white
riser tube. Tube was prefitted at the factory.
2. The distributor is permantly attached to the vortech----centering is
not necessary. The top of the distributor will extend above the
top of the tank (this was prefitted at the factory).
3. Cover the top opening of the distributor pipe before filling the tank
with media.
4. Pour all filter media provided with the unit into the top of the tank.
See page one for your specific model number of unit to determine
the amount of media to load into the mineral tank.
5. Remove the material used to cover the top opening of the
distributor pipe.
Logix Control Valve:
1. When facing the front of the Logix timer, the inlet connection
(Figure 1) is located on the left and the outlet connection is on the
right. The control valve's inlet and outlet connections are either
3/4” copper or PVC equipped with gasket and nut.
Figure 1
Install the 256 bypass valve (See Figure 2) with inlet and outlet
handles facing upward. Place gasket into nut and secure 3/4” copper

4
or PVC tail piece with a nut. Repeat the procedure for the outlet
connection.
DO NOT OVERTIGHTEN THE NUT.
Figure 2
2. The control valve's drain connection is 1/2" npt and is located on
the back of the bypass valve.
3. Turn the control valve upside down and ensure that the control
valve distributor o'rings are in place. Use silicone lubricant on the
o'rings.
4. Fill mineral tank with water before installing control valve.
5. Place the control valve onto the distributor pipe.
6. Thread the control valve hand tight to 20 foot pounds!
DO NOT OVERTIGHTEN!
**DO NOT USE PETROLEUM!**
**USE ONLY SILICONE **
Service and Drain Piping:
1. Pipe Filter into the service lines .The inlet and outlet connections
of the control valve are 3/4” copper or PVC and are located on
the back of the valve body. As you face the timer the inlet is on
the left and the outlet is on the right. Always follow local
plumbing codes when installing our water treatment equipment.
2. If sweat fittings are used, be sure soldering is done in such a
manner as not to allow heat to reach the control valve or bypass.
(If Schedule 80 PVC is used make sure to follow the proper
primer and solvent instructions.)
3. The drain line connection is located on the back of the bypass
valve as you face the timer. It is recommended you install a 1/2”
union on the drain line for servicing. The drain line must be of
adequate size to allow for full regeneration flow.

Figure 3
•The control valve drain connection is 1/2" npt.
•Never decrease the drain piping size to below 1/2”
•Maximum drain line length is 20 feet.
•Maximum drain line height is 6 feet above the
control valve.
•The drain line must be piped to an open air gap
(See Figure 3)
•Always follow local plumbing codes.

Electrical Requirements:
Always follow all local electrical codes when installing our water
treatment equipment.
1. Provide an 120v/60Hz properly grounded dedicated electrical
Outlet. (It’s very important that the polarity be correct)
Avoid using outlets that are switch controlled.
2. Maximum amperage required is 5 amps.

7
3. Make sure the electrical service provides power 24 hours per day.
We recommend installing a surge protector to protect unit from
power surges, which are not covered by warranty.
Logix Control Valve Electrical Connection:
Note: Do not touch the wiring harness between the Logix
timer and the motor, it’s positioning is critical and therefore
already installed at the factory.
1. Remove plastic control valve cover by spreading sides while
lifting.
2. Plug transformer into back of timer following existing wires.
3. Plug transformer into a properly grounded 120V/60 HZ electrical
outlet.
4. The screen will now display “253” then the “Time of Day”.
Filling Filter with Water:
Figure 4
1. Push the FOR REGENERATION button (Figure 4) on the
controller down for 5 seconds. This will initiate a manual
regeneration. You will notice a flashing hour glass during
regeneration.
The controller will indicate that the motor is turning the camshaft

8
to cycle C1 (BACKWASH). The controller will indicate the total
regeneration time remaining. Filling tank in this position allows air
to escape from drain.
Open the bypass inlet valve ¼ turn and allow water to flow into the
mineral tank at a slow rate.
Warning: IF WATER ENTERS THE TANK TOO FAST, ALL THE
MEDIA WILL BE FLUSHED TO DRAIN DURING START UP.
2. When water is running steadily at the drain, open the bypass
valve’s inlet and outlet to their maximum position.
Simultaneously press the SET and UP buttons on the controller for 1
second then release, the motor will advance the cam to C2. Once C2
is displayed simultaneously press the SET and UP buttons on the
controller for 1 second then release, the motor will advance the cam
to C3. Repeat this procedure until the timer enters the C7 (FAST
RINSE) position. The filter will go through the rinsing cycle and then
automatically advance to (REGENERATION COMPLETE) C0 and
Time of Day will be displayed. This is treated water.
Logix Control Valve Timer Settings:
Note: The control valve is preset at the factory. You only need to
set the time of day and number of days to regenerate, which is
preset at 1 am.

1) Press the SET button. The screen will show the Time of
Regeneration in blinking numbers.
2) To change the Time of Regeneration, use the UP or DOWN
arrows.
3) Press the SET button.
Regeneration Frequency Setting (the factory default is 7)
1) Press the SET button. The screen will show the Regeneration
frequency in blinking numbers.
2) To change the number, use the UP or DOWN arrows.
3) Press the SET button.
If you wish to regenerate on certain days ot the week, do
the following:
a. First, do steps above, but set at zero.
b. Press SET button until you reach the day you wish
to regenerate.
c. Press the UP or Down arrows to set the day.
d. Press the SET button to lock the day in.
e. Repeat process to select the next day of
regeneration.
NOTE: The days of Regeneration will be highlighted on the
screen.
Final Check:
1. Inspect the treated water to assure that the media fines (color)
have been flushed from the unit. Make sure the drain line

10
connection meets all plumbing codes and that the drain line size
can handle the backwash flow rate of the filter.
2. Make sure the Inlet and Outlet on bypass valve are open.
3. Make sure the control valve timer is plugged into an electrical
outlet with power 24 hours per day.
4. Check all piping for leaks.
Troubleshooting

11
Symptom: Water conditioner fails to regenerate. Dirty water.
Possible Cause
Solution
Power supply to 742 control has
been interrupted.
Determine reason for power
interruption and correct. Reset time of
day.
Water pressure lost.
Restore water pressure.
Corrupted programming of 742
Logix timer.
Reprogram timer assembly.
Defective 742 Logix timer.
Replace timer assembly.
Manual bypass valve is open.
Close manual bypass valve.
Leak at riser pipe seal.
Insure that riser pipe is properly
sealed at o’ring seal. Inspect pipe for
cracks.
Symptom: Loss of Media to Drain
Possible Cause
Solution
No flow control installed in drain
line.
Install drain line flow control.
Symptom: Leak to Drain
Possible Cause
Solution
No flow control installed in drain
line.
Install drain line flow control.
Insufficient water pressure.
Increase water pressure above 25
psig (172kPa) minimum.
Damaged valve disk or obstruction
in valve disk.
Inspect and if damaged, replace all
valve disks or remove obstruction.
Symptom: Loss of Water Pressure
Possible Cause
Solution
Fouled filter media bed due to iron
accumulation.
Clean control valve and rebed mineral
tank with new media.
Slots in riser pipe or laterals are
filled with media fines.
Inspect and clean distributor pipe slots
as needed.
