System Description:
The combination unit has a Logix top mounted automatic control
valve with an electronic timer 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

2
Combination Unit Positioning:
1. Place combination unit in desired position, far enough from walls
and other obstructions to allow for servicing the unit.
2. Place the combination unit within reasonable access to a
grounded 115V/60 HZ circuit and a legal drain line connection.
Combination Unit Tank Loading:
1. Remove yellow caplug from top of tank.DO NOT CUT white
riser tube. Tube was prefitted at the factory.
2. Center the distributor and make sure it is resting on the bottom of
the tank. The top of the distributor pipe 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
1” copper or pvc equipped with gasket and nut.
Figure 1
Install the 268 bypass valve (See Figure 2) with inlet and outlet
handles facing upward. Place gasket into nut and secure 1” copper
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 3/4" npt and is located on
the back of the control 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. Place the control valve onto the distributor pipe.
5. Thread the control valve hand tight to 20 foot pounds!
DO NOT OVERTIGHTEN!
**DO NOT USE PETROLEUM!**
**USE ONLY SILICONE **

4
Service and Drain Piping:
1. Pipe combination unit into the service lines .The inlet and outlet
connections of the control valve are 1” 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 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 valve as
you face the timer. It is recommended you install a ¾” 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 3/4" npt.
•Never decrease the drain piping size to below ¾”
•Maximum drain line length is 30 feet.
•Maximum drain line height is 6 feet above the
control valve.
•The drain line must be piped to an open airgap
(See Figure 3)
•Always follow local plumbing codes.
UNDER NO CIRCUMSTANCES SHOULD THERE BE A DIRECT
CONNECTION WITH SANITARY SEWAGE FACILITIES.

Electrical Requirements:
Always follow all local electrical codes when installing our water
treatment equipment.
1. Provide an 115v/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.
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.
Brine Tank:
1. The brine tank should be located directly beside the Combination
Unit mineral tank.
2. Connect the 3/8" poly tubing to the 3/8” white elbow compression
fitting located on the right side of the Logix control valve.
See Figure Below.
The 464 brine shutoff valve contains a float that controls the water
level in the brine tank. The float height was preset at the factory.

7
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 the existing wires.
3. Plug transformer into a properly grounded 120V/60 HZ electrical
outlet.
4. The screen will now display “268” then the “Time of Day”.
Filling Combination Unit 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
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.

8
Warning: IF WATER ENTERS THE TANK TOO FAST, ALL THE
RESIN 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.
3. 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 softener will go
through the rinsing cycle and then automatically advance to
(BRINE REFILL) C8 and fill the brine tank with the proper amount
of water.
4. The control valve will advance to C0 (REGENERATION
COMPLETE) and Time of Day will be displayed. This is
treated water.
Logix Control Valve Timer Settings:
Note: The control valve is set at the factory. You only need to set
the time of day and regeneration time if required, which is preset
at 2 am.

Res-Up (one quart is provided).
2. Make sure the drain line connection meets all plumbing codes
and that the drain line size can handle the backwash flow rate of
the softener.
3. Make sure the Inlet and Outlet on bypass valve are open.
4. Make sure the control valve timer is plugged into an electrical
outlet with power 24 hours per day.
5. Check all piping for leaks.
