INSTALLATION
Location selection
Location of a water treatment system is important. The following conditions are required :
●Level platform or floor.
●Room to access equipment for maintenance and adding regenerant (salt) to tank.
●Ambiant temperatures over 34°F (1°C) and below 120°F (49°C).
●Water pressure below 120 psi (8.27 bar) and above 20 psi (1.4 bar).
●Constant electrical supply to operate the controller.
●Total minimum pipe run to water heater of ten feet (three meters) to prevent
backup of hot water into system.
●Local drain for discharge as close as possible.
●Water line connections with shutoff or bypass valves.
●Must meet any local and state codes for site of installation.
●Valve is designed for minor plumbing misalignments. Do not support weight of
system on the plumbing.
●Be sur all soldered pipes are fully cooled before attaching plastic valve to the
plumbing.
Water line connection
A by-pass valve system should be installed on all water conditioning systems.
Bypass valves isolate the conditioner from the water system and allow unconditioned
water to be used. Service or routine maintenance procedures may also require that
the system is bypassed. Figure 1 and 2 show the three common bypass methods.

Drain line connection
1. If the backwash flow rate exceeds 5 gpm (22.7 Lpm) or if the unit is located
20-40 feet (6.1-12.2 m) from drain, use 3/4-inch (1.9 cm) tubing. Use appropriate
fittings to connect the 3/4-inch tubing to the 3/4-inch NPT drain connection on
valve.
2. The drain line may be elevated up to 6 feet (1.8 m) providing the run does not
exceed 15 feet (4.6m) and water pressure at the conditioner is not less than
40 psi (2.76 bar). Elevation can increase by 2 feet (61 cm) for each addditional
10 psi (0.69 bar) of water pressure at the drain connector.
3. Where the drain line is elevated but empties into a drain below the level of the
control valve, form a 7-inch (18 cm) loop at the far end of the line so that the
bottom of the loop is level with the drain line connection.This will provide an
adequate siphon trap.
Where the drain empties into an overhead sewer line, a sink-type trap must
be used.
Secure the end of the drain line to prevent it from moving.
NOTE : Standard commercial practices are expressed here. Local codes may
require changes to the following suggestions. Check with local authorities
before installing a system.

WARNING : Never insert drain line directly into a drain, sewer line or trap
(figure 3). Always allow an air gap between the drain line and the wastewater
to prevent the possibility of sewage being back-siphoned into the conditioner.

Overflow line connection
In the event of a mal function, the regenerant tank overflow will direct “overflow”
to the drain instead of spilling on the floor.This fitting should be on the side of the
cabinet or regenerant tank. Most tank manufacturers include a post for the tank
overflow connector.
To connect the overflow line, locate hole on side of tank. Insert overflow fitting into
tank and tighten with plastic thumb nut and gasket as shown (figure 4). Attach
length of 1/2-inch (1.3 cm) I.D. tubing (not supplied) to fitting and run to drain.
Do not elevate overflow higher than overflow fitting.
Do not tie into drain line of control unit. Overflow line must be a direct, separate
line from overflow fitting to drain, sewer or tub.Allow an air gap as per drain line
instructions.
Regenerant line connection
The regenerant line from the tank connects to the valve. Make the connections and
hang tighten. Be sure that the regenerant line is secure and free from air leaks. Even
as small leak may cause the regenerant line to drain out, and the conditioner will
not draw regenerant from the tank. This may also introduce air into the valve
causing problems with the valve operation.

START-UP OF YOUR SOFTENER
Initial start-up step-by-step instructions
Preliminary check of hydraulic parameters of the valve
Step 1 - Program system size
This step may be performed by your system’s OEM manufacturer.
In this case, proceed to step 2.
●Input system size - resine volume - in cubic feet or liters.
●Use UP and DOWN buttons to scroll through resin volume
choices.
●Choose the nearest volume to your actual system size.
●To choose a 3-cycle filter operation - press the DOWN button
until an “F” is displayed.
●Press the SET button to accept the system size you’ve selected.
If incorrect setting is programmed, see “Resetting the control”
on page 15.
1. Remove the cover from the valve. Removing the cover will
allow you to see that the camshaft is turning, and in which
cycle the camshaft is currently positioned.
2. With the supply water for the system still turned off, position
the bypass valve to the “not in bypass” (normal operation)
position.
3. Hold the REGEN button on the controller down for
5 seconds.This will initiate a manual regeneration.
The controller will indicate that the motor is turning the
camshaft to the cycle C1 (backwash) position by flashing an
hourglass. The controller will display the total regen time
remaining.
If you press and hold the SET button, the controller will
indicate the time remaining in the current cycle.
Step 2 - Placing conditioner into operation (conditioner start-up)
After you have performed the previous initial power-up steps, you will need to place the
conditioner into operation. Follow these steps carefully, as they differ from previous
Autotrol valve instructions.
This step must have been done by your OEM. You need to check that there is no mistake. In
fact, every setting stored in the electronic is largely dependant of hydraulic parameters
(injector/backwash) installed on the valve.
Please check that you are using the correct injector and backwash control in accordance with
the used pressure tank (see table page 14).

4. Fill the media tank with water.
A. While the controller is in cycle C1 (backwash), open the water supply valve very slowly to
approximately the 1/4 open position.
B. When all of the air has been purged from the media tank (water begins to flow steadily from
the drainline), open the main supply valve all of the way. This will purge the final air from the tank.
C. Allow water to run to drain until the water runs clear from the drain line. This purges any
refuse from the media bed.
D. Turn off the water supply and let the system stand for about five minutes.This will allow for
any air trapped to escape from the tank.
5. Add water to the regenerant tank (initial fill) - Conditioner only.
A. With a bucket or hose, add approximately 4 gallons (15 liters) of water to the regenerant tank.
B. If the tank has a salt platform in the bottom of the tank, add water until the water level is
approximately 1 inch (25 mm) above the platform.
6. Engage the refill cycle to prime the line between the regenerant tank and the valve
Conditioner only.
A. Slowly open the main water supply valve again, to the fully open position. Be sure not to open
too rapidly as that would push the media out the media tank.
B. Advance the controller to the refill position. From cycle C1 (backwash), press and hold the SET
button. This will display the current cycle.
While pressing the SET button, press the UP arrow to advance to the next cycle. Continue
to advance through each cycle until you have reached cycle C8 (refill).
C. With the water supply completely open, when you arrive at
cycle C8 (refill), the controller will direct water down through
the line to the regenerant tank. Let the water flow through the
line until all air bubbles have been purged from the line.
D. Do not let the water flow down the line to the tank for more
than one to two minutes, or the tank may overfill.
E. Once the air is purged from the line, press the SET button and
the UP button simultaneously to advance to cycle C0 (treated
water) position.
7. Draw water from the regenerant tank.
A. From the treated water position (cycle C0), advance the valve to the draw regenerant
position. Hold the REGEN button down for five seconds.
The controller will begin a manual regen, and advance the control valve to the cycle C1
(backwash). Press the SET and UP buttons to advance to cycle C2 (draw).
B. With the controller in this position,check to see that the water in the regenerant tank is being
drawn out of the tank. The water level in the tank should recede very slowly.
